KEY TAKEAWAYS Environmental consulting services, including the preparation of an Environmental Impact Statement (EIS), can frequently qualify as "related goods and services" under Queensland’s security of payment laws. If a developer refuses payment on the basis that your EIS was rejected by regulators or is "unfit for purpose", they must formally document this reasoning in a payment schedule within a strict 25-business-day window. A developer who misses this statutory deadline may become liable for the full invoice amount, regardless of their contractual grievances about the environmental assessment. Contractual clauses attempting to circumvent, delay, or restrict your statutory right to claim payment are likely void and unenforceable under the Building Industry Fairness (Security of Payment) Act 2017. The email from the developer's project manager is blunt: they are withholding your $80,000 milestone payment because the Department of Environment, Tourism, Science and Innovation (DETSI) rejected your Environmental Impact Statement (EIS). They allege your methodology was flawed, deem the report "unfit for purpose", and demand you rewrite the entire submission on your own dime before they release a single cent. While the client attempts to trap you in a drawn-out dispute over regulatory expectations and scoping boundaries, your firm is left carrying the financial risk of unpaid wages and operational overheads. This article outlines the precise statutory mechanism you can deploy to bypass these contractual delay tactics and enforce payment using Queensland’s security of payment laws. The 25-Day Window: Your Immediate Decision Sequence for an Unpaid EIS You have just been notified by the developer that they will not pay your milestone invoice because DETSI knocked back your EIS. The clock is ticking, and you need to know exactly how to force payment using a strict statutory timeframe before the project budget evaporates. What follows is the 25-business-day procedural sequence that escalates your payment claim and strips the developer of their ability to withhold funds indefinitely. Statutory BIF Act Rights vs Contractual Fee Recovery for Consultants When a developer refuses to pay for an environmental assessment, consultants typically assume their only option is to initiate a general breach of contract claim. However, security of payment in Queensland provides a parallel, much faster statutory recovery pathway. Suing for a breach of contract often drags your firm into a protracted debate over environmental methodology, scope of services, and whether the deliverable met regulatory standards. By contrast, the statutory mechanism is designed to temporarily sideline these complex contractual arguments about whether the EIS was defective, focusing instead on rapid cash flow recovery. The two pathways are not mutually exclusive, and this is where consultants often misread their position. Running a statutory claim does not extinguish the developer's contractual arguments about a defective EIS; it simply forces the money to move first and parks the merits fight for later. In practice, a developer who has lost on the statutory timeline will frequently pay, then immediately commence separate proceedings to claw the funds back on the "unfit for purpose" allegation. That is the system working as intended, "pay now, argue later", so the real question is not which mechanism is correct but whether your firm can hold the cash through a subsequent contractual challenge. This is why the statutory win is best treated as leverage rather than a final result. The developer's appetite to fund a clawback action over an $80,000 fee, once they are already out of pocket, is usually far lower than their appetite to simply withhold. In environmental disputes, developers frequently use the threat of a contractual counterclaim to starve a consultant of cash, making the statutory pathway a critical tool for neutralising that leverage. Because electing the correct pathway can significantly impact your leverage, you should consider obtaining construction law advice early to determine which mechanism best suits your commercial position. Activating the Law: EIS Preparation as "Related Goods and Services" In Queensland, environmental consulting services such as preparing an Environmental Impact Statement for a development project can, depending on their connection to the physical site works, fall within the definition of 'related goods and services' under the Building Industry Fairness (Security of Payment) Act 2017. Whether a particular engagement qualifies is a fact-specific question rather than an automatic entitlement. Many environmental professionals mistakenly believe these laws only protect civil contractors and tradespeople. However, under section 66 of the Building Industry Fairness (Security of Payment) Act 2017 (Qld), the definition of "related goods and services" extends to specified professional services relating to construction work, including architectural, design, surveying and quantity surveying services, as well as building, engineering, interior or exterior decoration and landscape advisory services. Whether a given environmental assessment falls within one of these limbs — most plausibly the engineering or landscape advisory limbs — is a fact-specific question that turns on the nature of the work and its demonstrable connection to construction work as defined in the Act. Each limb in section 66 is expressly confined to services "relating to construction work", so the strength of that nexus will often be decisive. Section 75 of the Building Industry Fairness (Security of Payment) Act 2017 (Qld) provides that a claimant who is entitled to a progress payment for these construction-related services may issue a statutory payment claim to the liable party. Note that the "liable party" is whoever is obliged to pay you under your contract — so if you are engaged not by the developer directly but through a head consultant, project manager, or principal contractor, your payment claim is directed at that counterparty, not the developer. Mapping the correct contractual chain before you serve is essential, because a claim served on the wrong party is wasted time against the clock. Because the application of this definition can be nuanced, whether a specific ecological survey or contamination monitoring program triggers this statutory protection may depend heavily on its direct, demonstrable nexus to the physical site development. Be aware, too, that section 75(2) imposes a longstop on when a payment claim can be made: generally the longest of the period worked out under the contract or six months after the construction work was last carried out, or the related goods and services were last supplied. Different, longer periods apply under section 75(3) where the claim relates to a final payment. A consultant sitting on an old unpaid EIS invoice should confirm which limb applies and that the window has not closed before serving. The 25-Business-Day Statutory Deadline for Developers Warning: Once you serve a valid statutory payment claim, a strict legal countdown begins. Under section 76 of the Building Industry Fairness (Security of Payment) Act 2017 (Qld), a client receiving a payment claim must respond with a formal payment schedule before the end of the response period. Section 76(4) defines that response period as the shorter of the period provided for in a written construction contract or 25 business days after the day the payment claim is given. A contract can shorten this period, but it cannot lengthen it. This is a rigid procedural mechanism that the developer cannot unilaterally pause, extend, or ignore simply because they are unhappy with the regulator's response to your environmental reporting. Defeating the "Unfit for Purpose" Contractual Defence The developer’s lawyers are likely pointing to a fitness for purpose clause in your consulting agreement, arguing the defective EIS breaches the contract and justifies withholding your funds. At this stage, you must rely on the statutory protections that override these contractual delay tactics. This section details how the BIF Act empowers you to cut through these aggressive legal threats and demand a formal payment schedule. Why a Rejected EIS Must Be Detailed in a Payment Schedule Expert insight: The most common developer error is treating correspondence as if it were a schedule. A project manager fires off an email saying the EIS was "knocked back" and payment is "on hold pending rectification", believing that puts the ball back in your court. It does not. Under section 69 of the Building Industry Fairness (Security of Payment) Act 2017 (Qld), a valid payment schedule must identify the payment claim to which it relates, state the amount the developer proposes to pay (often nil), and, where that amount is less than the claimed amount, state why — and if the withholding is because of a dispute, give the reasons for withholding — in enough detail that you can understand and respond to the basis for withholding. The second recurring mistake is vagueness dressed up as substance. A schedule that says the report was "deficient" or "did not meet the brief" without tying the deficiency to a specific scope item or contractual obligation gives an adjudicator very little to work with. Developers who cannot articulate exactly which methodology failed, and against which agreed requirement, routinely find their reasons given less weight. The tactical point for consultants is the reasons rule. Because section 69 requires the developer to state its reasons for withholding in the schedule itself, a respondent is generally confined at adjudication to the reasons raised in that schedule, so a developer who omits or under-pleads the "unfit for purpose" argument may be shut out from running it later. That is why a thin or late schedule is often more valuable to you than no schedule at all: it locks the developer into a weak position of their own making. The "No Contracting Out" Protection for Environmental Consultants Developers frequently try to rely on bespoke dispute resolution or set-off clauses to delay your cash flow when a regulatory submission is rejected. While these clauses are intended to permit the developer to withhold fees pending rectification, their effectiveness is directly limited by the BIF Act's anti-avoidance provisions. Under section 200 of the Building Industry Fairness (Security of Payment) Act 2017, a developer cannot rely on a contractual clause to restrict or delay a Queensland environmental consultant's statutory right to claim payment. The legislation explicitly provides that the Act's provisions have effect despite any provision to the contrary in an agreement. This works alongside section 74, which renders "pay when paid" provisions of no effect — a point of real significance where a developer attempts to make your payment contingent on a regulatory outcome, a third-party approval, or payment it receives from another party. If a client attempts to enforce a clause that contradicts the statutory payment mechanism, that provision is of no effect to the extent that it is contrary to the Act, purports to or does exclude, limit or change the Act's operation, or may reasonably be construed as an attempt to deter a person from taking action under the Act. Because this statutory pathway overrides contractual exposure and prevents contracting-out schemes, it is often necessary to engage a commercial lawyer in Queensland to assert your rights rather than accepting the developer's stonewalling. If you are staring at a withheld milestone payment right now, the fastest way to know where you stand is to send us the invoice and the developer's refusal email: to assert your rights rather than accepting the developer's stonewalling. If you are staring at a withheld milestone payment right now, the fastest way to know where you stand is to send us the invoice and the developer's refusal email: we run these security of payment claims for environmental consultants and can tell you whether the schedule window has lapsed and which enforcement route fits your position. Your right to payment is protected by Building Industry Fairness (Security of Payment) Act 2017 (Qld) s 200, which ensures the statutory process continues regardless of what the contract attempts to dictate. Weaponising Your Invoices as BIF Act Payment Claims Having the law on your side is meaningless if your administrative practices sabotage your claim before it even begins. You must now audit your internal invoicing procedures to ensure they strictly align with statutory requirements and withstand scrutiny in an adjudication forum. The steps below transform your standard milestone invoices into valid, legally binding payment claims under the BIF Act. Overcoming Generic Accounting Software Flaws in Consulting Invoices Expert insight: The problem almost always starts with the default line item your software drops in. Xero and MYOB will happily generate an invoice reading "Consulting Services, Stage 2" against a lump sum, and that single line tells an adjudicator nothing about whether the work connects to construction. When the developer disputes the nexus, that empty description becomes their best argument, not yours. The fix is to write the line items as if a stranger will have to decide the point in twenty minutes with no background. Reference the project, the site, and the construction-related purpose of the work: a line reading "Preparation of Environmental Impact Statement for proposed [project] development, [site] — ecological assessment and contamination monitoring in support of development approval" does far more work than "Environmental Advice". A practical habit that helps is pulling the description language straight from your scope of works or engagement letter, so the invoice, the contract, and the deliverable all speak the same vocabulary. Where consultants come unstuck is bundling genuinely construction-related work with unrelated advisory time under one vague heading, which invites the developer to argue the whole claim is out of scope. Itemise the construction-connected work separately so the valid portion can stand even if part of the claim is challenged. To ensure a milestone invoice qualifies as a valid payment claim under section 68 of the Building Industry Fairness (Security of Payment) Act 2017 (Qld), an environmental consultant must clearly identify the construction work or related goods and services to which the claim relates, state the amount claimed, and request payment of that amount. The 2020 Legislative Amendments to Implied Payment Claims The procedural mechanics for issuing a payment claim were significantly simplified following the passage of the Building Industry Fairness (Security of Payment) and Other Legislation Amendment Act 2020. These amendments systematically removed complex "reference date" hurdles that previously complicated the billing cycle for contractors and consultants. Furthermore, the legislative update removed the former requirement that a payment claim expressly state it is made under the Act. Under section 68(3) of the Building Industry Fairness (Security of Payment) Act 2017 (Qld), a written document bearing the word "invoice" is taken to satisfy the requirement that the document request payment. This means that a standard invoice for environmental consulting work is now generally capable of functioning as one of the Payment claims that trigger the statutory response timelines, provided it still identifies the construction-related work and states the amount claimed as required by section 68(1), without requiring specialised legal terminology on the document itself. Should You Still Endorse Your Environmental Invoices? Because the 2020 amendments removed the requirement to endorse a payment claim, a compliant invoice now functions as a payment claim whether or not it carries any reference to the Act. Endorsement is therefore no longer a condition of validity, and you should not assume that adding or omitting a BIF Act notation changes whether your invoice "counts" — that question turns on whether the document identifies the construction-related work, states the amount, and requests payment, as required by section 68(1). Some consultants nonetheless choose to add a short line noting that the invoice is a payment claim given under the Building Industry Fairness (Security of Payment) Act 2017 (Qld). The practical value of doing so is modest and is mainly about reducing later argument: it makes it harder for a developer to claim they did not appreciate the document started the statutory response clock. It does not, however, enlarge your rights, cure a defective invoice, or prevent a developer from raising a fitness for purpose or other contractual defence in a properly drafted payment schedule. Whether endorsement is worth adopting as a standing practice is a judgement call best made with construction law advice tailored to your contracts and billing systems, rather than treated as a universal rule. Enforcing the Debt When the Developer Misses the Deadline When the 25-business-day window closes without the delivery of a valid payment schedule, the commercial leverage shifts decisively in your favour. The next decision you face is choosing the fastest, most effective legal mechanism to recover your unpaid fees. This section details the distinct enforcement pathways available to secure your funds once the developer commits this critical procedural error. Automatic Liability for Failing to Provide a Payment Schedule If a developer fails to provide a valid payment schedule within 25 business days of receiving a payment claim, they become statutorily liable under Queensland law for the full amount claimed. This procedural failure triggers the consequence directly under the BIF Act. According to Building Industry Fairness (Security of Payment) Act 2017 (Qld) s 77, if a respondent given a payment claim does not respond as required by giving a payment schedule, they are liable to pay the amount claimed to the claimant on the due date for the progress payment. It is worth distinguishing the two provisions that operate here: section 77 fixes the amount owed (the full claimed amount) once the schedule window has lapsed, while section 78 is engaged by the separate failure to actually pay that amount by the due date, and it is section 78 that opens your enforcement options. It is important to keep two separate timeframes in mind: section 76 governs the window for giving a payment schedule, while section 73 fixes the due date on which payment becomes payable (where the contract is silent, 10 business days after the payment claim is given). The entitlement to the progress payment itself arises under section 70, while the definition of "progress payment" in section 64 expressly includes final payments, single or one-off payments, and milestone payments of the kind environmental consultants typically invoice. The legislation effectively converts the unpaid invoice into an actionable debt, superseding the developer's ability to raise ordinary contractual disputes as a preliminary reason for non-payment. Summary Judgment vs Statutory Adjudication Strategies Under Building Industry Fairness (Security of Payment) Act 2017 (Qld) s 78, when a client fails to pay the owed amount under a statutory payment claim, the consultant is entitled to pursue recovery through one of two primary procedural mechanisms: Initiating civil proceedings to recover the unpaid portion as a debt owing in a court of competent jurisdiction (frequently pursued via a summary judgment application under the Uniform Civil Procedure Rules 1999 (Qld)), with interest recoverable at the rate applied under section 73 of the Building Industry Fairness (Security of Payment) Act 2017 (Qld) and the Civil Proceedings Act 2011 (Qld). Applying for rapid BIF Act adjudication to secure a binding determination outside the traditional court system. Selecting the appropriate enforcement route depends heavily on the complexity of the matter, which is why considering formal dispute resolution strategies early is crucial. For a clean $80,000 claim where the developer has simply missed the schedule deadline, summary judgment is often the sharper tool. Once the right to a schedule has lapsed, the debt is owing by operation of the statute, and the developer's contractual grievances about the EIS are generally not a defence to the debt itself, which is exactly the kind of matter summary judgment is built for. Adjudication is fast and avoids the court list, but it carries adjudicator fees and still produces a determination the developer can seek to resist or unwind on jurisdictional grounds. The practical trade-off is that adjudication gets you a decision quickly but may invite a second round, whereas a well-run summary judgment application on a missed deadline can dispose of the matter in one hit. The decision usually turns on how cleanly the developer defaulted. A total failure to provide any schedule points towards summary judgment; a late or defective schedule that still raises arguments often points towards adjudication, where those arguments can be tested and dismissed on the merits. Suspending Environmental Fieldwork for Non-Payment Warning: While section 98 of the Building Industry Fairness (Security of Payment) Act 2017 (Qld) does permit a claimant to suspend ongoing construction-related services for non-payment, the decision to down tools carries significant legal risk and must be heavily qualified by strict adherence to statutory notice procedures. If you are considering suspending work for non-payment, you must strictly follow the written warning requirements outlined in the legislation and the QBCC Security of Payment Guide. Under section 98, you may suspend only after the amount owed has not been paid by the due date, you have given the respondent written notice of your intention to suspend, and at least two business days have passed since that notice was given. Note also that under section 98 the respondent remains liable for any loss or expense you incur if work is removed from the contract, and you are generally protected from liability for loss suffered by the respondent during a properly executed suspension. A failure to execute the statutory notice procedure correctly can expose your consulting firm to allegations of contractual repudiation. Before suspending environmental fieldwork, such as critical contamination monitoring, you should carefully consider whether the suspension might independently trigger breaches of environmental authority conditions. Conclusion That $80,000 milestone invoice for your rejected Environmental Impact Statement does not have to become a bad debt just because the developer prefers to litigate your methodology. When a client attempts to use a regulatory rejection to starve your firm of cash flow, the balance of power can shift the moment you recognise that environmental consulting work may, depending on its nexus to the construction work, fall within Queensland’s security of payment legislation. The statutory framework is specifically designed to prevent developers from using drawn-out contractual disputes as an excuse to withhold progress payments. You now know that your environmental assessments and ecological surveys can, where they are sufficiently connected to construction work, qualify as "related goods and services", potentially granting you the same statutory enforcement rights as a civil contractor. You also know that developers cannot simply hide behind "fitness for purpose" clauses; they must formally articulate their reasons for withholding funds in a payment schedule within a strict 25-business-day window. If they miss this deadline, section 77 of the BIF Act operates to make them liable for the entire debt, bypassing their contractual grievances altogether. Your immediate next step should be to audit your current accounts receivable and standard invoice templates. Ensure your accounting software clearly identifies the construction-related services provided and explicitly endorses the BIF Act on every milestone invoice. If you are currently sitting on an unpaid invoice where the 25-business-day window has expired without a valid payment schedule, the developer may already be liable for the full amount — and the sooner you move, the stronger your position. Send us the invoice, the engagement letter, and the developer's correspondence, and we will assess whether the schedule window has lapsed and prepare the documentation to pursue summary judgment or statutory adjudication. FAQs Does the BIF Act apply to environmental consulting services in Queensland? Yes, environmental consulting services such as preparing an Environmental Impact Statement typically qualify as "related goods and services" under the BIF Act. This classification allows environmental consultants to issue statutory payment claims and pursue rapid debt recovery for unpaid construction-related work. What happens if a developer misses the 25-business-day deadline to respond to my invoice? If a developer fails to provide a valid payment schedule within 25 business days of receiving a payment claim, they become statutorily liable for the full amount claimed. You can then typically pursue debt recovery by applying for summary judgment in court or commencing statutory adjudication. Can a developer use a "fitness for purpose" clause to withhold payment for a rejected EIS? While a developer may attempt to rely on a fitness for purpose clause, section 200 of the BIF Act generally voids any contractual provision that attempts to restrict or delay your statutory right to claim payment. The developer must still detail any contractual grievances in a formal payment schedule within the strict statutory timeframe to legally withhold funds. Do I need to explicitly state "this is a claim under the BIF Act" on my environmental invoices? Under the 2020 legislative amendments, an invoice does not strictly need this endorsement to be considered a payment claim in Queensland. However, best practice suggests you should still explicitly endorse your invoices to clearly notify the developer of their statutory obligations and limit evidentiary risks during disputes. Can I suspend my environmental fieldwork if the developer refuses to pay? You may have a statutory right to suspend construction-related services for non-payment, provided you strictly follow the written warning procedures required by the BIF Act. However, suspending work carries significant legal risk and can expose your firm to liability if the cessation of work triggers a breach of environmental authority conditions. What should I do if a developer sends an email refusing payment instead of a formal payment schedule? An informal email stating they will not pay often fails to meet the strict legal requirements of a statutory payment schedule. If the developer does not provide a compliant schedule within 25 business days, they are likely liable for the full debt, which may allow you to commence adjudication or seek summary judgment. What if I was engaged through a head consultant or project manager rather than the developer directly? Your statutory payment claim is directed at the party contractually obliged to pay you, which may be a head consultant, project manager, or principal contractor rather than the developer. The BIF Act process still applies, but you must identify the correct "liable party" in your contractual chain before serving, as a claim served on the wrong entity will not start the statutory clock. This is a common structure in environmental work and is worth confirming early, particularly for sole practitioners and small firms where adjudicator fees and cash flow pressure make a mis-served claim especially costly.

KEY TAKEAWAYS The Electrical Safety and Other Legislation Amendment Act 2024 (Qld) introduced a "negligence" fault element for Category 1 offences under the Work Health and Safety Act 2011 (Qld) from 30 August 2024, which can significantly lower the prosecution threshold for inherited site hazards. Section 272A expressly prohibits builders from using insurance policies to indemnify against monetary WHS penalties, meaning regulatory fines are likely to be paid directly from your own pocket. The prohibition commenced in stages, with the bans on entering into and providing such arrangements applying from 28 September 2024 and the ban on taking the benefit of an existing arrangement applying from 28 September 2025. Company officers may face personal liability under section 272B if they authorise or permit their building company to hold or benefit from prohibited WHS penalty insurance arrangements. Before assuming control of a delayed site, incoming builders should formally audit and document the absence of Safe Work Method Statements (SWMS) to help establish a baseline for section 27 due diligence defences. You have just signed the contract to take over a half-finished residential build in Brisbane after the original contractor went into liquidation — a scenario that carries its own web of insolvency and completion-cost exposures beyond the safety issues covered here. You walk onto the site on day one and see the previous builder’s roofing trades still working—without edge protection and without a signed Safe Work Method Statement (SWMS) in sight. At that exact moment, the financial pressure of the delayed schedule collides with the reality that you are now the Person Conducting a Business or Undertaking (PCBU) in charge. Under Queensland's newly amended WHS legislation, ignoring those missing documents because it is "not your mess" is no longer just a regulatory risk—it can expose you to criminal negligence. Immediate Triage: Halting Work and Auditing the Inherited Site You have just walked onto a delayed, half-built site taken over from a previous builder, only to find trades actively working without SWMS for high-risk activities. At this exact moment, you face a critical decision: immediately halt the non-compliant work to protect your licence, or allow it to continue and risk inheriting the previous supervisor’s safety liabilities. This section outlines the immediate triage steps required to secure the site and draw a hard procedural line between the previous builder's breaches and your tenure. Suspending non-compliant trades in the first 48 hours The immediate priority upon taking over a site is to formally suspend any trades who cannot produce a valid SWMS for high-risk construction work. While an incoming builder may be eager to get the project moving, pausing work limits the new PCBU's exposure to inherited risks and manages the transition of safety duties. The WHS duty a builder owes in respect of subcontractor workers on site does not wait for a new subcontract to be signed — as a person with management or control of the workplace under section 20 of the WHS Act, your duty attaches the moment those trades are working under your control. A Queensland PCBU assuming control of a construction site must verify that all high-risk construction work is supported by a valid SWMS before allowing trades to commence or continue work. For the site supervisor who is physically first on the ground, this is a first-hour task, not a first-week one: walk the site, identify every high-risk activity in progress, and stand down any trade who cannot hand you a current, signed SWMS on the spot. The supervisor's contemporaneous note of who was stood down and when becomes part of the builder's due diligence record. It is a common mistake for incoming site managers to let "minor" trades finish out the day to avoid conflict or keep the client happy. Doing so can inadvertently transfer liability for that non-compliant work directly to your company. If trades refuse to supply updated safety documentation or comply with your site rules, you may need to consider your options for terminating a construction contract or subcontract, depending on the terms of your engagement. Documenting existing site hazards before assuming PCBU control Before allowing any work to resume under your control, you must establish a clear administrative and physical baseline of the site's condition. This evidence is critical to separating the previous builder's safety breaches from your own WHS obligations as a builder in Queensland. Photograph the physical environment: Capture images of existing unsafe scaffolding, missing temporary fencing, and unprotected penetrations before any of your staff or trades touch them. Audit the paperwork: Formally record the absence of safety documentation, induction logs, and SWMS left by the previous contractor. Issue formal notices: Send written directives to all inherited trades stating that previous safety approvals are void and new SWMS must be submitted and approved before re-entry. Treat this internal stop as seriously as a regulator-issued prohibition notice or improvement notice in Queensland — if SafeWork attends and issues one, your own documented directive shows you were already managing the hazard under the WHS Act. Distinguishing Statutory WHS Liabilities from Contractual Delay Exposure When managing a distressed site takeover, you must separate your statutory duty to halt unsafe work under the WHS Act from your contractual exposure for delaying the project. While pausing the build to rectify missing SWMS or unsafe scaffolding will cause timeline pressures, statutory WHS obligations generally take priority over contractual schedules, and a contractual deadline is not a defence to a safety breach. The commercial pressure to reach practical completion quickly does not legally excuse a PCBU from their primary duty of care. Courts and tribunals do not accept contractual deadlines or client frustration as a defence to safety breaches. A builder who allows unsafe work to continue simply to avoid liquidated damages risks trading a manageable commercial dispute for a statutory prosecution. That trade is rarely rational once the figures are compared: liquidated damages on a stalled residential build typically run to a capped daily rate, whereas a Category 1 or industrial manslaughter conviction reaches into the millions and, for officers, personal imprisonment. The delay is recoverable; a conviction is not. The 2024 Category 1 Trap: Why "Negligence" Changes the Legal Threshold The days of requiring regulators to prove a builder acted with flagrant "recklessness" to secure a Category 1 conviction are over. With the introduction of the negligence standard, failing to enforce basic site safety protocols—like verifying SWMS on a site you just took over—is a statutory liability pathway that can now directly expose you to the most severe penalties under the WHS Act 2011. How the section 31 amendment removes the "recklessness" requirement Introduced by the Electrical Safety and Other Legislation Amendment Act 2024 (Qld) and commencing on 30 August 2024, the amendment fundamentally lowers the prosecution threshold by introducing "negligence" as a fault element for a Category 1 offence — a change builder operating in Queensland should treat as current law, not a proposal on the horizon. Historically, establishing this offence required proof of reckless conduct, which often proved difficult for regulators to demonstrate in complex residential building scenarios. Under the Electrical Safety and Other Legislation Amendment Act 2024 (Qld), a builder's failure to do what is reasonably practicable—within the meaning of section 18 of the WHS Act—amounting to gross negligence, may now be sufficient to trigger severe penalties. Under section 31 of the WHS Act, builders commit a Category 1 offence if they expose any individual owed a health and safety duty to a risk of death, serious injury, or illness without reasonable excuse. Courts may consider the failure to rectify an inherited site hazard as negligent conduct, which can increase the likelihood of conviction if an incident occurs. Under the 2024 amendments to the Queensland WHS Act, a Category 1 offence can be established by proving negligence, removing the previous burden of proving reckless conduct. Expanding liability to sub-trades, site visitors, and clients Expert insight: In practice, the people who get hurt on a residential takeover are rarely the roofers everyone is watching. They are the homeowner who "just popped in" to see progress, the concrete truck driver reversing up a churned-up driveway, or the client's teenage kid wandering the frame on a Saturday. These are exactly the individuals a builder assumes are someone else's problem — and exactly the ones the primary duty of care under section 19 of the WHS Act does not carve out. On a residential job, the client feels a sense of ownership over the site and will let themselves in unannounced. That is the single most common blind spot on handovers. A worker refusing to enter an unsafe zone will usually make noise about it; a roaming homeowner will walk straight under an unguarded penetration without a second thought. The primary duty under section 19(2) extends to persons other than workers, and the amended section 31 sharpens this because you no longer need to have been reckless about that visitor's safety. If you knew clients were wandering the site and took no reasonable steps — no signage, no induction, no controlled access — a failure to guard against a foreseeable visitor injury can now be framed as negligence rather than mere oversight. Tactically, the fix on day one is simple and worth documenting: lock down access with perimeter fencing and a single controlled entry point, put a standing written direction to the client that inspections happen by appointment and escorted only, and add delivery drivers to your traffic management and induction process rather than treating them as passing traffic. If you are unsure how these expanded duties impact your site handover protocols, consider obtaining advice from a WHS lawyer or Queensland building and construction lawyers. The industrial manslaughter exposure of inherited missing SWMS Example: Suppose you assume control of a residential project and allow the previous builder's roofing contractor to finish laying sheets for the afternoon without first verifying their SWMS or ensuring edge protection is compliant. If that roofer falls, your failure to halt work and verify safety documentation can be relied on as evidence of gross negligence under the new statutory framework. A fall from height builder prosecution is one of the most common enforcement scenarios in residential construction, and inheriting the hazard does not soften the regulator's approach. With 188 Australian workers losing their lives at work in 2024, regulators remain focused on site fatalities, and inheriting another builder's hazard without acting may significantly elevate your WHS prosecution risk. The numbers on conviction are not abstract: a Category 1 offence exposes an individual to a maximum penalty in the hundreds of thousands of dollars and up to five years' imprisonment, and a body corporate to a maximum in the millions—penalties being expressed in penalty units and converted to dollar figures under section 181B of the Penalties and Sentences Act 1992 (Qld) — while an industrial manslaughter conviction under Part 2A of the Work Health and Safety Act 2011 (Qld)—section 34C for a PCBU and section 34D for a senior officer—carries a maximum of 20 years' imprisonment for an individual and, for a body corporate, a maximum of 100,000 penalty units (in the order of $10 million or more, depending on the prevailing penalty unit value). Under these circumstances, courts may assess your inaction as directly exposing the worker to a risk of death or serious injury, satisfying the elements of a Category 1 or industrial manslaughter charge. The Section 272A Insurance Prohibition: Fines Paid from Your Own Pocket If you are assuming your Management Liability or D&O insurance policy will simply cover the cost of a regulatory fine if a site handover goes wrong, you are mistaken. Section 272A voids any policy purporting to indemnify you against WHS penalties, transferring the cost directly to the company — and potentially to you personally via section 272B. The statutory ban on indemnifying against WHS monetary penalties The section 272A prohibition creates three distinct offences: it is an offence, without reasonable excuse, to enter into, to provide, or to take the benefit of an insurance contract or other arrangement that purports to indemnify a person for all or part of a monetary penalty under the WHS Act, each carrying a maximum penalty of 500 penalty units. It is an offence for a builder or an individual to hold, enter into, or benefit from an insurance policy that covers monetary fines imposed under the WHS Act. This prohibition means that any existing insurance policies are void to the extent that they offer this specific cover, as reinforced by WorkSafe Queensland’s guidance on the prohibition on insurance. Why your Management Liability policy is void for regulatory fines Expert insight: The conversation with a principal usually goes the same way. They forward the broker's summary, point to the "statutory liability" or "WHS defence costs" line, and treat it as proof they are covered. What they have actually bought is a lawyer to run the defence — not a cheque to pay the fine if the defence fails. That distinction is where the pain lands. Defence costs cover keeps the meter running on your representation during the investigation and prosecution. The monetary penalty on conviction is a separate line item, and s272A voids any part of the policy that purports to pick it up. The trap is that both sit in the same policy schedule, often under headings that read as if they are one product. Principals see a healthy limit against "statutory liability" and assume the whole outcome is insured. When the penalty is handed down, they discover the insurer will fund the fight but not the fine. Two practical steps are worth taking now. Ask your broker in writing to confirm, clause by clause, which parts of the policy respond to defence costs versus any monetary penalty — and expect the penalty response to be nil or void in Queensland. And do not restructure the policy to disguise a penalty indemnity as something else, because holding or benefiting from that arrangement is itself the s272A offence. If you are uncertain about how this affects your specific coverage, it is prudent to seek advice from a commercial lawyer in Queensland. Section 272B personal liability for officers authorising prohibited cover The prohibition on insurance also creates a separate exposure channel for company executives. Under the section 272B officer liability provisions, company officers of a building company—an "officer" taking the meaning given by the Corporations Act 2001 (Cth) as applied by the dictionary to the WHS Act—can be held personally liable if they authorise or permit the company to enter into a prohibited insurance arrangement for WHS fines. As outlined in the Review of the Work Health and Safety Act 2011 Final Report, if the body corporate commits an offence against section 272A, courts may determine that directors or senior managers who permitted the conduct are also guilty of the offence. Working With a WHS Lawyer to Activate Your Due Diligence and "Reasonable Excuse" Defences Assuming control of a compromised site does not mean you are automatically guilty of the previous builder's sins—provided you act immediately. By establishing clear administrative boundaries and fulfilling your officer obligations from day one, you can map out a solid procedural mechanism for defending against regulator scrutiny. Establishing a "reasonable excuse" position against inherited safety breaches Documenting the state of an inherited site and immediately halting unsafe work serves as a critical evidence factor if the regulator intervenes. If a SafeWork Queensland builder investigation occurs shortly after you take control, comprehensive day-one documentation can help establish that any exposure occurred with "reasonable excuse", an element the prosecution must exclude under section 31 of the WHS Act. This evidence demonstrates that the hazard was pre-existing and that you were actively managing the risk according to your statutory duties. A Queensland builder may rely on the "reasonable excuse" element within section 31, together with evidence of due diligence, if they can evidence that they took all reasonable, immediate steps to rectify inherited safety hazards upon assuming site control. Meeting section 27 officer due diligence obligations on a newly taken-over site Officer duties under WHS law for builders are proactive, not passive: officers of a building company must exercise due diligence under section 27 of the WHS Act, and this duty is acute when acquiring an active project. Satisfying this obligation requires you to direct the new site supervisor to conduct an immediate safety audit, verify the licences of all inherited trades, and demand updated SWMS before allowing tools to be picked back up. Courts typically look for evidence of these immediate, system-driven actions to assess whether an officer took reasonable steps to understand and mitigate the hazards associated with the newly acquired site. Why subcontract indemnity clauses cannot shield builders from primary WHS duties Incoming builders often require existing trades to sign new subcontracts containing strong subcontract indemnity clauses designed to transfer liability. While the intended function of an indemnity clause is to protect the head contractor from a subcontractor's failures, this protection may be limited by statutory prohibitions against contracting out of WHS duties, namely section 14 (which provides that a duty cannot be transferred to another person) and section 272 of the WHS Act (which renders any term of an agreement purporting to exclude, limit or modify a WHS duty void). A subcontract indemnity might cover commercial losses or property damage, but it cannot legally transfer a PCBU's primary duty of care. If a court assesses that a builder relied on paper indemnities while failing to physically verify SWMS or site safety, the builder may still face direct prosecution under the WHS Act, rendering the contractual clause ineffective against regulatory fines or Category 1 charges. Conclusion Standing on that delayed residential build in Brisbane and watching roofers work without edge protection or valid Safe Work Method Statements might feel like a purely commercial problem left behind by the previous contractor. It is not. Under the amended Queensland WHS legislation, inheriting and ignoring another builder's safety hazard is a direct legal exposure issue. The Electrical Safety and Other Legislation Amendment Act 2024 (Qld) means that regulators no longer need to prove you were "reckless" to pursue a Category 1 offence—a failure to take reasonable care that exposes an individual to risk can now trigger negligence charges. Furthermore, the section 272A insurance prohibition ensures that if you are fined for turning a blind eye to those missing SWMS, your Management Liability policy cannot legally cover the penalty. Those fines may ultimately come directly out of your company’s capital or your personal assets. Do not let the commercial pressure of a delayed schedule dictate your safety compliance. Before any trade picks up a tool on an inherited site, formally suspend high-risk work, photograph the existing hazards, and demand updated SWMS. By drawing a hard procedural line on day one, you establish the baseline required for your section 27 due diligence defence and protect your licence from the previous builder's mistakes. The Electrical Safety and Other Legislation Amendment Act 2024 (Qld) introduced a "negligence" fault element for Category 1 offences under the Work Health and Safety Act 2011 (Qld) from 30 August 2024, which can significantly lower the prosecution threshold for inherited site hazards. Section 272A expressly prohibits builders from using insurance policies to indemnify against monetary WHS penalties, meaning regulatory fines are likely to be paid directly from your own pocket. The prohibition commenced in stages, with the bans on entering into and providing such arrangements applying from 28 September 2024 and the ban on taking the benefit of an existing arrangement applying from 28 September 2025. Company officers may face personal liability under section 272B if they authorise or permit their building company to hold or benefit from prohibited WHS penalty insurance arrangements. Before assuming control of a delayed site, incoming builders should formally audit and document the absence of Safe Work Method Statements (SWMS) to help establish a baseline for section 27 due diligence defences. You have just signed the contract to take over a half-finished residential build in Brisbane after the original contractor went into liquidation — a scenario that carries its own web of insolvency and completion-cost exposures beyond the safety issues covered here. You walk onto the site on day one and see the previous builder’s roofing trades still working—without edge protection and without a signed Safe Work Method Statement (SWMS) in sight. At that exact moment, the financial pressure of the delayed schedule collides with the reality that you are now the Person Conducting a Business or Undertaking (PCBU) in charge. Under Queensland's newly amended WHS legislation, ignoring those missing documents because it is "not your mess" is no longer just a regulatory risk—it can expose you to criminal negligence. Immediate Triage: Halting Work and Auditing the Inherited Site You have just walked onto a delayed, half-built site taken over from a previous builder, only to find trades actively working without SWMS for high-risk activities. At this exact moment, you face a critical decision: immediately halt the non-compliant work to protect your licence, or allow it to continue and risk inheriting the previous supervisor’s safety liabilities. This section outlines the immediate triage steps required to secure the site and draw a hard procedural line between the previous builder's breaches and your tenure. Suspending non-compliant trades in the first 48 hours The immediate priority upon taking over a site is to formally suspend any trades who cannot produce a valid SWMS for high-risk construction work. While an incoming builder may be eager to get the project moving, pausing work limits the new PCBU's exposure to inherited risks and manages the transition of safety duties. The WHS duty a builder owes in respect of subcontractor workers on site does not wait for a new subcontract to be signed — as a person with management or control of the workplace under section 20 of the WHS Act, your duty attaches the moment those trades are working under your control. A Queensland PCBU assuming control of a construction site must verify that all high-risk construction work is supported by a valid SWMS before allowing trades to commence or continue work. For the site supervisor who is physically first on the ground, this is a first-hour task, not a first-week one: walk the site, identify every high-risk activity in progress, and stand down any trade who cannot hand you a current, signed SWMS on the spot. The supervisor's contemporaneous note of who was stood down and when becomes part of the builder's due diligence record. It is a common mistake for incoming site managers to let "minor" trades finish out the day to avoid conflict or keep the client happy. Doing so can inadvertently transfer liability for that non-compliant work directly to your company. If trades refuse to supply updated safety documentation or comply with your site rules, you may need to consider your options for terminating a construction contract or subcontract, depending on the terms of your engagement. Documenting existing site hazards before assuming PCBU control Before allowing any work to resume under your control, you must establish a clear administrative and physical baseline of the site's condition. This evidence is critical to separating the previous builder's safety breaches from your own WHS obligations as a builder in Queensland. Photograph the physical environment: Capture images of existing unsafe scaffolding, missing temporary fencing, and unprotected penetrations before any of your staff or trades touch them. Audit the paperwork: Formally record the absence of safety documentation, induction logs, and SWMS left by the previous contractor. Issue formal notices: Send written directives to all inherited trades stating that previous safety approvals are void and new SWMS must be submitted and approved before re-entry. Treat this internal stop as seriously as a regulator-issued prohibition notice or improvement notice in Queensland — if SafeWork attends and issues one, your own documented directive shows you were already managing the hazard under the WHS Act. Distinguishing Statutory WHS Liabilities from Contractual Delay Exposure When managing a distressed site takeover, you must separate your statutory duty to halt unsafe work under the WHS Act from your contractual exposure for delaying the project. While pausing the build to rectify missing SWMS or unsafe scaffolding will cause timeline pressures, statutory WHS obligations generally take priority over contractual schedules, and a contractual deadline is not a defence to a safety breach. The commercial pressure to reach practical completion quickly does not legally excuse a PCBU from their primary duty of care. Courts and tribunals do not accept contractual deadlines or client frustration as a defence to safety breaches. A builder who allows unsafe work to continue simply to avoid liquidated damages risks trading a manageable commercial dispute for a statutory prosecution. That trade is rarely rational once the figures are compared: liquidated damages on a stalled residential build typically run to a capped daily rate, whereas a Category 1 or industrial manslaughter conviction reaches into the millions and, for officers, personal imprisonment. The delay is recoverable; a conviction is not. The 2024 Category 1 Trap: Why "Negligence" Changes the Legal Threshold The days of requiring regulators to prove a builder acted with flagrant "recklessness" to secure a Category 1 conviction are over. With the introduction of the negligence standard, failing to enforce basic site safety protocols—like verifying SWMS on a site you just took over—is a statutory liability pathway that can now directly expose you to the most severe penalties under the WHS Act 2011. How the section 31 amendment removes the "recklessness" requirement Introduced by the Electrical Safety and Other Legislation Amendment Act 2024 (Qld) and commencing on 30 August 2024, the amendment fundamentally lowers the prosecution threshold by introducing "negligence" as a fault element for a Category 1 offence — a change builder operating in Queensland should treat as current law, not a proposal on the horizon. Historically, establishing this offence required proof of reckless conduct, which often proved difficult for regulators to demonstrate in complex residential building scenarios. Under the Electrical Safety and Other Legislation Amendment Act 2024 (Qld), a builder's failure to do what is reasonably practicable—within the meaning of section 18 of the WHS Act—amounting to gross negligence, may now be sufficient to trigger severe penalties. Under section 31 of the WHS Act, builders commit a Category 1 offence if they expose any individual owed a health and safety duty to a risk of death, serious injury, or illness without reasonable excuse. Courts may consider the failure to rectify an inherited site hazard as negligent conduct, which can increase the likelihood of conviction if an incident occurs. Under the 2024 amendments to the Queensland WHS Act, a Category 1 offence can be established by proving negligence, removing the previous burden of proving reckless conduct. Expanding liability to sub-trades, site visitors, and clients Expert insight: In practice, the people who get hurt on a residential takeover are rarely the roofers everyone is watching. They are the homeowner who "just popped in" to see progress, the concrete truck driver reversing up a churned-up driveway, or the client's teenage kid wandering the frame on a Saturday. These are exactly the individuals a builder assumes are someone else's problem — and exactly the ones the primary duty of care under section 19 of the WHS Act does not carve out. On a residential job, the client feels a sense of ownership over the site and will let themselves in unannounced. That is the single most common blind spot on handovers. A worker refusing to enter an unsafe zone will usually make noise about it; a roaming homeowner will walk straight under an unguarded penetration without a second thought. The primary duty under section 19(2) extends to persons other than workers, and the amended section 31 sharpens this because you no longer need to have been reckless about that visitor's safety. If you knew clients were wandering the site and took no reasonable steps — no signage, no induction, no controlled access — a failure to guard against a foreseeable visitor injury can now be framed as negligence rather than mere oversight. Tactically, the fix on day one is simple and worth documenting: lock down access with perimeter fencing and a single controlled entry point, put a standing written direction to the client that inspections happen by appointment and escorted only, and add delivery drivers to your traffic management and induction process rather than treating them as passing traffic. If you are unsure how these expanded duties impact your site handover protocols, consider obtaining advice from a WHS lawyer or Queensland building and construction lawyers. The industrial manslaughter exposure of inherited missing SWMS Example: Suppose you assume control of a residential project and allow the previous builder's roofing contractor to finish laying sheets for the afternoon without first verifying their SWMS or ensuring edge protection is compliant. If that roofer falls, your failure to halt work and verify safety documentation can be relied on as evidence of gross negligence under the new statutory framework. A fall from height builder prosecution is one of the most common enforcement scenarios in residential construction, and inheriting the hazard does not soften the regulator's approach. With 188 Australian workers losing their lives at work in 2024, regulators remain focused on site fatalities, and inheriting another builder's hazard without acting may significantly elevate your WHS prosecution risk. The numbers on conviction are not abstract: a Category 1 offence exposes an individual to a maximum penalty in the hundreds of thousands of dollars and up to five years' imprisonment, and a body corporate to a maximum in the millions—penalties being expressed in penalty units and converted to dollar figures under section 181B of the Penalties and Sentences Act 1992 (Qld) — while an industrial manslaughter conviction under Part 2A of the Work Health and Safety Act 2011 (Qld)—section 34C for a PCBU and section 34D for a senior officer—carries a maximum of 20 years' imprisonment for an individual and, for a body corporate, a maximum of 100,000 penalty units (in the order of $10 million or more, depending on the prevailing penalty unit value). Under these circumstances, courts may assess your inaction as directly exposing the worker to a risk of death or serious injury, satisfying the elements of a Category 1 or industrial manslaughter charge. The Section 272A Insurance Prohibition: Fines Paid from Your Own Pocket If you are assuming your Management Liability or D&O insurance policy will simply cover the cost of a regulatory fine if a site handover goes wrong, you are mistaken. Section 272A voids any policy purporting to indemnify you against WHS penalties, transferring the cost directly to the company — and potentially to you personally via section 272B. The statutory ban on indemnifying against WHS monetary penalties The section 272A prohibition creates three distinct offences: it is an offence, without reasonable excuse, to enter into, to provide, or to take the benefit of an insurance contract or other arrangement that purports to indemnify a person for all or part of a monetary penalty under the WHS Act, each carrying a maximum penalty of 500 penalty units.

FAQs What is a Category 1 offence under the Queensland WHS Act 2011? A Category 1 offence occurs when a person with a health and safety duty exposes an individual to a risk of death or serious injury without reasonable excuse. Following the Electrical Safety and Other Legislation Amendment Act 2024 (Qld), which took effect on 30 August 2024, this offence can now be triggered by negligence, rather than requiring the regulator to prove reckless conduct. This means Queensland builders may face severe penalties for failing to take reasonable care on site. Can my building company use insurance to pay for WHS fines in Queensland? No, section 272A of the Queensland WHS Act strictly prohibits entering into or benefiting from insurance policies that indemnify against monetary penalties. Policies are void to the extent they offer this cover, meaning any regulatory fines must typically be paid from company or personal assets. However, depending on the specific policy wording, insurance may still cover legal defence costs incurred during an investigation. Can company directors be personally liable if the business has prohibited WHS insurance? Yes, company officers can face personal liability under section 272B if they authorise or permit their building company to hold prohibited insurance for WHS fines. If the body corporate commits an offence under section 272A, directors who permitted the arrangement are likely to be deemed to have also committed the offence. This may create a significant personal financial risk for Queensland builder principals. Do I need a SWMS before taking over high-risk work from a previous builder? Yes, a Queensland PCBU must ensure a valid Safe Work Method Statement (SWMS) is in place before any high-risk construction work commences or resumes. Inheriting a site does not remove your primary duty of care, and allowing trades to continue without documentation may be relied on as evidence of negligence. Halting work to verify safety paperwork can help establish a due diligence defence if the regulator investigates. Will a subcontract indemnity clause protect me from WHS prosecution in Queensland? A subcontract indemnity clause cannot legally transfer a head contractor's primary statutory WHS duties to a subcontractor. While these clauses are often used to allocate commercial risk, statutory prohibitions against contracting out of safety duties severely limit their effectiveness in regulatory matters. Courts may still hold the head contractor directly liable if they fail to physically manage site safety, regardless of the paper indemnity. Does my duty of care extend to site visitors and delivery drivers? Yes, the WHS duties of a Queensland builder extend to any individual whose health and safety may be put at risk by the construction work, including visitors, clients, and delivery drivers. The Category 1 and industrial manslaughter provisions apply to exposing any owed individual to risk, not just direct employees. Builders must enforce site safety compliance strictly across all parties to effectively manage this exposure. This guide is for informational purposes only and does not constitute legal advice.

KEY TAKEAWAYS The Environmental Protection (Efficiency and Streamlining) and Other Legislation Amendment Act 2026 (Qld) creates a framework for Environmentally Relevant Activity (ERA) codes, which are standard, non-negotiable conditions made by regulation. Where a code applies, or where environmental authority conditions are imposed or amended after tender, the required water management methodology may significantly exceed tender pricing assumptions. Contractors who must upgrade their dewatering or discharge systems to meet these statutory requirements should urgently assess their entitlement to a variation claim under the legislative change provisions of their contract. Amendments to section 497 of the Environmental Protection Act 1994 (Qld) give the Queensland Department of the Environment, Tourism, Science and Innovation (DETSI) two years to commence most summary proceedings. For more serious offences, including environmental harm offences and breaches of environmental authority conditions, it has three years, creating long-tail exposure. A head contractor that holds the environmental authority commits an offence if a subcontractor breaches its conditions, unless it can make out the statutory defence in section 431(4). Generic flow-down clauses may not provide sufficient contractual protection. You have just received the final environmental conditions for a new regional pipeline project, and the margin has evaporated before the first excavator tracks onto the site. At tender, your estimating team priced a standard settlement pond methodology for trench dewatering. Now, the conditions that will govern the works, whether set by an ERA code or by an environmental authority issued or amended after tender, mandate a sophisticated flocculation and zero-discharge water treatment setup. The principal expects you to absorb the upgrade, arguing it is merely a compliance cost of doing business. The project manager needs an immediate strategy to bridge the gap between statutory compliance and commercial recovery without inadvertently accepting the cost or breaching the law. The Disconnect Between Tender Pricing and DETSI's ERA Codes You are looking at a regulator-mandated site methodology that can cost several times what you priced at tender, and the commercial pressure is real. The way out is to separate what you must do from what you can recover: satisfy the regulator on site, then run the commercial mechanism that lets you claim the cost back. Separating Statutory DETSI Compliance from Your Contractual Variation Entitlement A critical error water infrastructure contractors make when hit with unexpected site rules is conflating their regulatory obligations with their commercial entitlements. These are two separate systems, and confusing them costs money in both directions. The requirement to adhere to water management standards is a regulatory duty enforced by the State; it does not automatically grant you a right to claim those compliance costs from the principal. Compliance with Queensland's Environmental Protection Act 1994 (Qld) is a strict statutory duty, while recovering the cost of that compliance from a principal depends entirely on the specific legislative change clauses within the construction contract. If you attempt to withhold compliance on the site until the principal agrees to pay for the upgraded methodology, you risk facing immediate regulatory enforcement. Conversely, executing the new methodology without first triggering the correct contractual notice procedures may forfeit your commercial entitlement to a variation. Identifying the Methodology Gap Between Tendered Dewatering and Final ERA Codes The regulatory baseline for water infrastructure projects is shifting under the Environmental Protection (Efficiency and Streamlining) and Other Legislation Amendment Act 2026 (Qld). The Act establishes the ERA code framework and amends the limitation periods in section 497 of the Environmental Protection Act 1994 (Qld). The ERA code provisions commence on a date fixed by proclamation, so before relying on them, check that they are in force and that a code has actually been made for your activity. This legislation allows a regulation to declare an activity a code-managed ERA. The activity can then be carried out in compliance with a standard ERA code instead of under a bespoke environmental authority, which bypasses the lengthy application process for site-specific conditions. However, the trade-off for this streamlined approval process is the imposition of rigid, standard-form conditions on activities like trench dewatering, spoil management, and temporary extraction. Of the roughly 9,300 environmental authorities administered by DETSI, more than 30% have been identified as potentially suitable for conversion to code-managed ERAs. For Queensland water infrastructure contractors, this standardisation creates an immediate methodology gap. A cheaper, site-specific extraction and discharge methodology that was historically acceptable may now be non-compliant under the blanket terms of a new ERA code, leaving the contractor to absorb the difference between the tendered methodology and the one actually required. This risk is best managed at the estimating stage, not discovered on site. When you price water management at tender, qualify the assumption you are pricing to. State the specific methodology and discharge standard your rate is based on, and expressly exclude the cost of complying with any ERA code or environmental authority condition made or amended after the tender date. A clear qualification does two things: it protects your margin if the standard shifts, and it strengthens any later variation by putting a documented tender baseline on the record. Be careful about who made the regulatory choice. The scheme is elective: a proponent may carry out a code-managed ERA under the code or apply for an environmental authority instead. If the contractor chose the code pathway after tender, the principal will argue that the resulting cost flows from the contractor's own choice rather than a change in legislation. The strongest variation position arises where the code or its conditions were made or amended by regulation after the relevant contract date, or where the principal made the choice and directed the contractor to work under the code. Why You Cannot Ignore or Negotiate an Inflexible ERA Code Condition A tempting shortcut, when a restrictive ERA code collides with your civil methodology, is to proceed with the tendered dewatering plan and negotiate with the regulator later. That shortcut is likely to trigger severe statutory penalties. While opting into an ERA code saves upfront approval time, the Queensland Department of the Environment, Tourism, Science and Innovation typically treats these standard-form conditions as non-negotiable baselines. Because the code conditions are rigid, physically deviating from the prescribed water treatment or discharge parameters can be an immediate offence. Once the relevant provisions commence by proclamation, contravening an ERA code is an offence under the new section 435A of the Environmental Protection Act 1994 (Qld), inserted by the 2026 amendments. Until then, confirm the current reprint, because the section 435A presently in force deals with a different subject matter. Contravening an environmental authority condition is an offence under section 430, with a maximum penalty of 4,500 penalty units, rising to 6,250 penalty units or five years' imprisonment if the contravention is wilful. If the discharge also causes harm, separate offences apply. Unlawfully causing serious environmental harm (section 437) carries up to 4,500 penalty units, or 6,250 penalty units or five years' imprisonment if wilful. Material environmental harm (section 438) carries up to 1,665 penalty units, or 4,500 penalty units or two years' imprisonment if wilful. Environmental nuisance (section 440) carries up to 600 penalty units, or 1,665 penalty units if wilful. Serious environmental harm is defined in section 17 and material environmental harm in section 16; serious harm includes harm causing property loss or remediation costs above the statutory threshold amount, which is set at $100,000 for the financial year ending 30 June 2023 and indexed to the consumer price index each subsequent financial year under section 17. The exposure from a single non-compliant discharge event can dwarf the cost you were trying to save. Regulators are also unlikely to retroactively approve a cheaper methodology once site works have commenced. Expert Insight: The conflict usually surfaces at the discharge point, not the treatment train. A code or environmental authority condition will often fix a hard numeric trigger— a turbidity or pH release limit, or a "no visible discharge to waters" standard — that assumes continuous monitoring and a fully closed treatment loop. Your tendered settlement pond methodology was built around batch testing and gravity release, and those two things are simply incompatible. Even where no condition is breached, sediment-laden discharge can trigger a standalone offence. Section 440ZG of the Environmental Protection Act 1994 (Qld) prohibits unlawfully depositing a prescribed water contaminant in waters, a roadside gutter or stormwater drainage, or anywhere it could reasonably be expected to move into them. It also prohibits unlawfully releasing stormwater run-off that results in a build-up of earth in those places. The Act's own example is a building site where soil may be washed into an adjacent roadside gutter. The maximum penalty is 600 penalty units, or 1,665 penalty units if the deposit or release is wilful. Prescribed water contaminants are listed in schedule 10 of the Environmental Protection Regulation 2019 (Qld). A similar trap appears with temporary extraction, although it usually arises under a different statute. Under the Water Act 2000 (Qld), taking or interfering with water without authorisation is an offence under section 808(1) and (2). Taking water while contravening the measurement requirements attached to an authorisation is an offence under section 808(3). Each carries a maximum of 1,665 penalty units, and executive officers can be liable under section 828. An authorisation to take water may cap take volumes and impose metering requirements, where the civil program assumed opportunistic dewatering into an existing drainage line. Once you read the conditions and authorisations against the earthworks sequence, the gap is rarely a "top-up" — it is a different water management system. Attempting to negotiate the code after issue tends to fail for a structural reason, not an attitudinal one. When you opt into a code-managed ERA, the regulator is not exercising discretion over your site; it is applying a standard instrument. There is usually no delegated officer with power to soften a code condition for one project, so the "negotiation" you are seeking does not exist within that pathway. In practice, the only genuine flexibility sits in reverting to a site-specific approval, which reintroduces the full assessment timeline you opted into the code to avoid—a delay that can run to months on a project where the earthworks sequence cannot wait. That is the trade-off to weigh honestly: the code buys speed at the cost of rigidity, and the site-specific pathway buys flexibility at the cost of time. Formulating the Variation Claim to the Superintendent for Unforeseen Water Management Costs The regulator's mandate is non-negotiable, and the site team must implement the upgraded water treatment system to avoid prosecution—but you cannot afford to absorb the cost. What follows is the practical sequence: ground the claim in the right clause, hit the deadlines that keep your rights alive, and know your next move when the superintendent says no. Grounding Your Claim in the Contract’s Legislative Change Clauses When the methodology you priced at tender becomes illegal due to new regulatory conditions, you must select the correct contractual mechanism to claim the difference in cost. Contractors frequently attempt to claim unexpected regulatory impositions as latent conditions. However, latent condition clauses generally apply to physical site variations—such as unexpected rock or contaminated soil—not to changes in the rules governing how the work must be performed. In Queensland construction contracts, contractors may often seek cost recovery for newly imposed environmental conditions by relying on legislative or statutory change clauses, provided the change occurred after the date the clause specifies (often the tender closing date or the date of contract). Standard forms such as AS 4000–1997 deal with this through a change in legislative requirements clause (clause 11.2), read with the definition of Legislative Requirements in clause 1. That definition extends beyond Acts to regulations and to the requirements of organisations having jurisdiction. This matters because ERA codes are made by regulation and environmental authority conditions are imposed by DETSI. To ground a claim successfully, you must show three things: that the ERA code or condition falls within the contract's definition of Legislative Requirements, that it was made or changed after the date the clause specifies, and that complying with it directly increases your cost of performing the work. Heavily amended contracts often narrow this clause or delete it altogether, so read the version you signed rather than the standard form. The Danger of Missing Contractual Time Bars for Environmental Variations and the Limits of the prevention principle Failing to adhere to strict contractual notice periods is the most common reason legitimate variation claims for regulatory changes are defeated. Under most commercial contracts, you must notify the superintendent of the legislative change and the anticipated cost impact within a tightly defined window. Unamended AS 4000 requires notice under the change clause and a written claim within 28 days under clause 41.1. Amended government and council contracts commonly shorten these windows, in some cases to five to seven business days. Crucially, the clock for these time bar clauses typically starts ticking from the moment you become aware (or ought reasonably to have become aware) of the new ERA code or environmental authority condition, not from the date you physically commence the upgraded dewatering works. Courts generally enforce time bars according to their terms, so your entitlement depends on strict compliance with the notice provisions. Arguments such as the prevention principle may help where the principal's own conduct caused the delay, but they are uncertain and no substitute for a timely notice. If you hold your variation claim until the end of the month, you run a severe risk that the principal will rely on the time bar to reject the claim entirely, forcing you to absorb the regulatory costs. What to Do When the Superintendent Rejects the Environmental Variation Superintendents frequently reject variations based on new ERA codes by asserting that the contractor bore the risk of environmental compliance at tender. This is especially common in Queensland council and government contracts, where principals often run heavily amended standard forms that push environmental risk downstream. When faced with this scenario, you must immediately trigger the contract's dispute resolution framework while continuing to perform the works. If you are challenging the superintendent's assessment, the first step is usually issuing a formal notice of dispute in strict compliance with the contract's specified timeframe. You must clearly separate the regulatory necessity of the work from the commercial liability for its cost. Before the matter escalates to formal litigation, executing a well-structured dispute strategy can often resolve the issue through executive negotiation, mediation, expert determination, or arbitration, depending on the dispute resolution pathway your contract prescribes. Consider obtaining construction law advice early to ensure your notices are contractually compliant and preserve your commercial leverage. Alongside the contractual process, the Building Industry Fairness (Security of Payment) Act 2017 (Qld) offers a faster statutory pathway. You can include the disputed variation in a payment claim under section 75, within the time limits in section 75(2). The principal must respond with a payment schedule within the period set by the contract or 15 business days, whichever ends first (section 76(1)). If the scheduled amount is less than the amount claimed, you may apply for adjudication within 30 business days after receiving the payment schedule (section 79(2)(b)(iii)). Head contractors must also attach a supporting statement about subcontractor payments to each payment claim (section 75(7)). Adjudication does not finally decide the entitlement, but it can put money in your hands while the contractual dispute runs its course. Your Prosecution Risk Under the EP Act While the Variation is Disputed While you battle the principal over who pays for the new dewatering system, you are likely acutely aware that you cannot afford to halt the physical site works. The enforcement reality of the EP Act is unforgiving: the regulator has years to prosecute, and liability can reach past the company to you personally. Both points are set out below. The Two- and Three-Year Limitation Periods for Environmental Offences Contractors can face significant long-tail exposure under the amended Environmental Protection Act 1994 (Qld), which extends the time regulators have to pursue non-compliance. Under section 497(1), most summary proceedings must now start within two years after the offence is committed. Under section 497(2), a relevant summary proceeding must start within three years. Section 497(3) defines a relevant summary proceeding as a summary proceeding for any indictable offence against the Act, or for one of 12 listed offences. The listed offences include breaching the general environmental duty (section 319(2)), carrying out an ERA without an environmental authority (section 426(1)), contravening an environmental authority condition (section 430(3)), an EA holder's failure to ensure compliance (section 431(2)), unlawfully causing serious or material environmental harm (sections 437(2) and 438(2)) and causing an environmental nuisance (section 440). Offences outside that definition, such as depositing prescribed water contaminants under section 440ZG, remain subject to the two-year limit. Where an enforceable undertaking has been given, proceedings must start within two years after the undertaking is contravened or its withdrawal is agreed under section 509. Three further qualifications matter. First, section 497 limits only summary proceedings. It does not apply where an indictable offence is prosecuted on indictment. Under section 494, an indictable offence is any offence carrying two years' imprisonment or more, such as wilfully contravening a condition or wilfully causing serious or material environmental harm. Second, the new periods apply only to offences committed after the amendments commenced. Under the transitional provision in section 846, the former section 497 continues to govern earlier offences. Third, time runs from when the offence is committed, and a harm offence is committed when the harm actually occurs, not when the act that caused it was done (R v Dumble [2021] QCA 161). This creates a latent risk trap, because enforcement action may occur long after the physical works have finished and the project has moved into the defects liability phase. Expert Insight: The practical difficulty with a three-year window is that your defence evidence is generated daily on site and then quietly lost. The records that decide these matters — pH and turbidity readings, pump run logs, weather and rainfall observations, disposal and tanker dockets, and the calibration certificates for the monitoring instruments themselves — tend to live in a site office that demobilises at practical completion. Twelve months later, the laptop has been wiped and the field books are in a skip. The retention decision most contractors get wrong is treating these as project records rather than defence records. A disposal docket is not just proof you paid the waste contractor; it is often the only contemporaneous evidence of where contaminated spoil actually went and in what volume. If the docket is gone, you are left arguing from memory against a regulator holding a sample result. The tactical move is to set retention against the limitation window, not the defects liability period. A harm offence is not committed until the harm occurs, and indictable offences prosecuted on indictment are not caught by section 497 at all. So treat three years from the last relevant works as an absolute floor rather than a safe harbour, hold records longer where there is any risk of delayed harm, capture the monitoring data in a form that survives the site handover, and make sure whoever calibrated the meters can still be identified. The contractors who defend these matters comfortably are the ones who preserved the boring paperwork before anyone alleged a breach. Why Executive Officers May Face Personal Liability for Project Breaches The corporate structure of a contracting firm may not shield its leadership from the consequences of severe environmental breaches on a project site. Section 493 of the EP Act explicitly extends liability to the executive officers of corporations. Under section 493(2), if a corporation commits an offence against any provision of the Act, each of its executive officers also commits an offence. Schedule 4 defines an executive officer as a person who is concerned with, or takes part in, the management of the corporation, whether or not the person is a director. The net therefore extends well beyond the board to senior managers. Under section 493(3), evidence that the corporation committed the offence is evidence that each executive officer did too. Former officers are not safe either. Under section 493(5) and (6), where the corporation's act or omission happens before the offence is committed, the provision extends to officers who were in office when the act or omission happened. An example is a discharge decision that causes serious environmental harm months later. Liability can also chain upward. If a subcontractor breaches an environmental authority condition (section 430), the EA holder commits an offence under section 431(2). The holder's executive officers can then be charged under section 493(2). Two further provisions complete the picture. Under section 492(2), acts or omissions of the company's employees and agents within the scope of their actual or apparent authority are treated as the company's own, unless the company proves it took all reasonable steps to prevent them. That is how a site team's illegal discharge methodology becomes a corporate offence and, through section 493, a leadership problem. An independent subcontractor will not usually be a representative under section 492(4); exposure for its conduct arises under section 431 instead. On the other side, section 493(4) gives an executive officer a defence if they prove either that they took all reasonable steps to ensure the corporation complied with the provision, or that they were not in a position to influence the corporation's conduct in relation to the offence. The officers who can rely on that defence are the ones who can point to board-level environmental reporting, properly resourced compliance systems and documented responses to warning signs. The General Environmental Duty Under Section 319 and the Defence in Section 493A Section 319(1) of the EP Act imposes a general environmental duty. A person must not carry out an activity that causes, or is likely to cause, environmental harm unless the person takes all reasonably practicable measures to prevent or minimise the harm. The duty cuts both ways. Under section 319(2), breaching it is itself an offence where the breach causes, or is likely to cause, serious or material environmental harm. But complying with it is also the basis of the main defence to the harm offences. Under section 493A(3), it is a defence to certain charges to prove that the act was done while carrying out an activity that is lawful apart from the Act, and that you complied with the general environmental duty. Those charges are unlawfully causing serious or material environmental harm or an environmental nuisance, and unlawfully depositing a prescribed water contaminant. The defence has limits. It applies only to the relevant acts listed in section 493A(1). It does not answer a charge of contravening an environmental authority condition under section 430, which is often the charge that matters most on a regulated site. Separately, an act authorised by an environmental authority is not unlawful at all (section 493A(2)(d)). A defendant who complied with an applicable code of practice is taken to have complied with the general environmental duty (section 493A(5)). A code of practice is a different instrument from an ERA code, and the two should not be confused. Relying on this defence requires robust, contemporaneous documentation, and the burden of proof is on you. In deciding what measures were reasonably practicable, the court must consider matters including the nature of the harm, the sensitivity of the receiving environment, the current state of technical knowledge, the likelihood of the measures succeeding and their financial implications (section 319(4)). It may also consider whether you did the following (section 319(5)): installed, used and maintained plant and systems to minimise risk; maintained systems to identify, assess and control risks; handled substances appropriately; and provided adequate information, instruction, supervision and training. You must show that the systems in place on site were reasonable given the specific risks, even if they ultimately failed to prevent a discharge event. In practice, inspectors are persuaded far more by a documented decision trail than by the hardware itself. What tends to satisfy the standard is evidence that you identified the risk in advance, considered the available controls, and can show why the control you chose was reasonable at the time — a signed water management plan, toolbox records, and a maintenance and inspection log that runs continuously up to the discharge event. The evidence that repeatedly falls short is the after-the-fact reconstruction: a plan dated the week of the incident, or photographs of controls with no record they were ever checked. A control you installed but never monitored is often treated as no control at all. The distinction the inspector is drawing is between a system that was genuinely operating and one that merely existed on paper. Shielding the Head Contractor from Subcontractor EA Breaches You are likely frustrated that despite investing heavily in a compliant water management plan, a subcontractor taking a shortcut could expose your entire operation to regulatory penalties. This section explains how statutory strict liability flows upward and why standard subcontracts often fail to insulate the head contractor, offering actionable steps to quarantine your business from downstream negligence. The Statutory Trap of "Acting Under" an Environmental Authority The EP Act creates a dual liability structure that captures both the subcontractor physically carrying out the work and the party holding the overarching approval. Section 430 applies to "a person who is the holder of, or is acting under, an environmental authority". Under section 430(2), that person must not wilfully contravene a condition of the authority (maximum 6,250 penalty units or five years' imprisonment). Under section 430(3), the person must not contravene a condition of the authority (maximum 4,500 penalty units). Crucially, section 431(1) provides that "the holder of an environmental authority must ensure everyone acting under the authority complies with the conditions of the authority." Under section 431(2), if another person acting under the authority, such as a subcontractor, commits an offence against section 430, the holder also commits an offence. Under section 431(3), the subcontractor's conviction is evidence against the holder. So if your subcontractor breaches a condition, for example by disposing of contaminated spoil contrary to the authority, DETSI may prosecute your company directly as the EA holder. Illegal dumping may also attract separate offences under the Waste Reduction and Recycling Act 2011 (Qld). The liability is not absolute. Under section 431(4), the holder has a defence if it proves three things: it issued appropriate instructions and used all reasonable precautions to ensure compliance; the offence was committed without its knowledge; and it could not have stopped the offence by exercising reasonable diligence. That defence, not the subcontract indemnity, is the head contractor's main protection against prosecution, and it is won or lost on paperwork. The records that matter are written instructions setting out the EA conditions, site inductions, supervision and audit records, and evidence of how non-compliance was detected and corrected. Before relying on any of this, confirm who actually holds the environmental authority. On many water infrastructure projects, the holder is the principal or asset owner, not the head contractor. In that case, the head contractor's exposure arises under section 430 as a person acting under the authority, not under section 431. And where the activity is carried out under an ERA code rather than an environmental authority, sections 430 and 431 do not apply at all; the relevant offence is contravening the ERA code. The same provision cuts the other way for subcontractors. If you are engaged to work under someone else's environmental authority, section 430 makes you personally exposed to the conditions in an instrument you may never have seen. Before you sign, ask for the actual EA conditions that will govern your scope, price the water management obligations they impose rather than the ones you assumed at quote, and refuse to carry open-ended compliance risk for a methodology the head contractor controls. A subcontractor who treats the EA as the principal's problem is the one most likely to be standing beside the holder when the regulator brings proceedings. Why Generic "Comply with All Laws" Flow-Down Clauses May Fail To mitigate this upward flow of statutory liability, head contractors frequently rely on back-to-back subcontract provisions, often inserting a generic clause requiring the subcontractor to "comply with all laws." However, relying on these broad statements can leave you exposed. The effectiveness of a flow-down clause depends heavily on how specific it is. Indemnities are construed strictly, and any ambiguity is resolved in favour of the party giving the indemnity (Andar Transport Pty Ltd v Brambles Ltd (2004) 217 CLR 424). A generic compliance clause is therefore unlikely to provide a robust indemnity against the holder's liability under section 431. To secure adequate contractual protection, the subcontract should explicitly attach the specific EA conditions and tie the indemnity directly to a breach of those exact provisions. Expert Insight: The drafting that survives is specific about three things: what the subcontractor must comply with, what triggers the indemnity, and what the indemnity actually covers. A "comply with all laws" clause fails on all three because it never names the environmental authority, so the subcontractor can plausibly argue it never agreed to carry the specific conditions that were breached. The technique that works is to append the actual EA conditions as a schedule to the subcontract and impose them as an express obligation, rather than folding them into a general compliance covenant. Tie the indemnity to a breach of those scheduled conditions, and draft it to respond to the head contractor's own liability as EA holder, including legal costs, investigation and clean-up costs, and rectification, not merely to third-party claims. Take specific advice before drafting the indemnity to cover fines themselves. An indemnity against a criminal penalty may be unenforceable on public policy grounds, particularly where the indemnified party's own conduct contributed to the offence. A generic indemnity often only answers claims by others, which is not what happens when the regulator prosecutes you directly. Two practical points decide whether the indemnity is worth anything. First, back it with insurance and financial capacity requirements, because an indemnity from an insolvent subcontractor after a serious spill is a piece of paper—subcontractor insolvency in Queensland is common enough that the covenant is only as good as the entity standing behind it. Second, understand the limits of the proportionate liability regime. The proportionate liability provisions in chapter 2, part 2 of the Civil Liability Act 2003 (Qld) cannot be contracted out of (section 7(3)). However, they apply only to apportionable claims as defined in section 28, which broadly means claims for economic loss or property damage arising from a breach of a duty of care. They will rarely affect recovery of your own regulatory costs, but they can reduce what you recover where the claim is framed in negligence. Treat the clause as recovering your exposure where it can, not as a guarantee that you walk away whole. Conclusion That sudden realisation that your tendered dewatering plan is now non-compliant under the new DETSI conditions is a defining moment for your project's profitability. The requirement to install a complex flocculation and zero-discharge treatment system is not just a site hurdle; it is a critical intersection of statutory enforcement and commercial risk. The regulator expects strict adherence to the applicable ERA code or environmental authority conditions, and the principal will expect you to absorb the financial fallout unless you actively protect your position. As we have covered, your obligations to the State and your commercial entitlements under the contract are entirely separate mechanisms. DETSI has two years to commence most summary proceedings and three years for the more serious offences. An EA holder also commits an offence when a subcontractor breaches its conditions, unless it can prove the section 431(4) defence. Both points highlight the danger of treating this as a simple administrative issue. You must quarantine your business from downstream negligence using precise subcontract flow-downs while simultaneously executing a flawless legislative change variation to recover the upgrade costs. Do not wait for the superintendent to question your upgraded water management setup or for the regulator to issue an infringement notice. Review your project's specific environmental authority conditions against your tendered methodology today. If a methodology gap exists, draft a legislative change notice to the superintendent before your contractual time bar expires and your right to a variation is forfeited. If you are facing a DETSI-driven cost blowout, a rejected variation or a subcontractor compliance issue, contact Merlo Law to have your notices, contract and EA conditions reviewed before the deadline passes. FAQs Can I claim a variation if a new DETSI ERA code increases my dewatering costs? Yes, you may be able to claim a variation if three conditions are met: your Queensland construction contract includes a legislative change clause, the ERA code or condition falls within the contract's definition of legislative requirements, and it was made or changed after the date the clause specifies. The claim is weaker if your side chose the code pathway after tender. Recovery also depends on strictly complying with the contract's time bar notice provisions. If you fail to notify the superintendent within the prescribed window, you may forfeit your commercial entitlement. What happens if my subcontractor breaches a condition of the site's environmental authority? Under section 431 of the Environmental Protection Act 1994 (Qld), the holder of the environmental authority commits an offence if a subcontractor acting under that authority breaches its conditions. The holder has a defence under section 431(4) if it proves it issued appropriate instructions, used all reasonable precautions, did not know of the offence and could not have stopped it with reasonable diligence. Subcontracts should also include explicit flow-down clauses tied directly to the EA conditions to provide commercial protection. How long does DETSI have to prosecute a contractor for an environmental offence? Under section 497 of the Environmental Protection Act 1994 (Qld), most summary proceedings must start within two years after the offence is committed. Relevant summary proceedings must start within three years; these cover indictable offences and listed serious offences such as environmental harm and breaches of environmental authority conditions. Offences committed before the amendments commenced remain subject to the former limits, and the time limits do not apply to indictable offences prosecuted on indictment. Contractors should retain compliance records, such as disposal dockets and dewatering logs, well beyond the standard defects liability period. Can company directors be held personally liable for environmental breaches on a Queensland construction site? Yes. Under section 493 of the Environmental Protection Act 1994 (Qld), if a corporation commits an offence, each executive officer also commits an offence, and the corporation's offence is evidence against them. An executive officer is anyone concerned with or taking part in the corporation's management. An officer has a defence if they prove they took all reasonable steps to ensure compliance, or were not in a position to influence the corporation's conduct in relation to the offence. Can I ignore a standard-form ERA code condition if it contradicts my tendered civil methodology? No. Once the ERA code provisions commence by proclamation, contravening an ERA code is an offence under the new section 435A of the Environmental Protection Act 1994 (Qld), as inserted by the 2026 amendments. Contravening an environmental authority condition is an offence under section 430. Regulators generally treat these standard-form conditions as non-negotiable baselines, so any operational deviation can trigger enforcement action, regardless of the commercial impact on your project's budget. Does a generic "comply with all laws" clause protect a head contractor from subcontractor environmental breaches? A generic compliance clause often fails to provide a robust contractual indemnity against the liability imposed on EA holders under the Environmental Protection Act 1994 (Qld). Because indemnities are construed strictly, subcontracts should explicitly incorporate the specific environmental authority conditions and tie indemnities directly to a breach of those exact terms. The holder's main protection against prosecution remains the statutory defence in section 431(4). This guide is for informational purposes only and does not constitute legal advice.

KEY TAKEAWAYS The Electrical Safety and Other Legislation Amendment Act 2024 (Qld) introduced a "negligence" fault element for Category 1 offences under the Work Health and Safety Act 2011 (Qld) from 30 August 2024, which can significantly lower the prosecution threshold for inherited site hazards. Section 272A expressly prohibits builders from using insurance policies to indemnify against monetary WHS penalties, meaning regulatory fines are likely to be paid directly from your own pocket. The prohibition commenced in stages, with the bans on entering into and providing such arrangements applying from 28 September 2024 and the ban on taking the benefit of an existing arrangement applying from 28 September 2025. Company officers may face personal liability under section 272B if they authorise or permit their building company to hold or benefit from prohibited WHS penalty insurance arrangements. Before assuming control of a delayed site, incoming builders should formally audit and document the absence of Safe Work Method Statements (SWMS) to help establish a baseline for section 27 due diligence defences. You have just signed the contract to take over a half-finished residential build in Brisbane after the original contractor went into liquidation — a scenario that carries its own web of insolvency and completion-cost exposures beyond the safety issues covered here. You walk onto the site on day one and see the previous builder’s roofing trades still working—without edge protection and without a signed Safe Work Method Statement (SWMS) in sight. At that exact moment, the financial pressure of the delayed schedule collides with the reality that you are now the Person Conducting a Business or Undertaking (PCBU) in charge. Under Queensland's newly amended WHS legislation, ignoring those missing documents because it is "not your mess" is no longer just a regulatory risk—it can expose you to criminal negligence. Immediate Triage: Halting Work and Auditing the Inherited Site You have just walked onto a delayed, half-built site taken over from a previous builder, only to find trades actively working without SWMS for high-risk activities. At this exact moment, you face a critical decision: immediately halt the non-compliant work to protect your licence, or allow it to continue and risk inheriting the previous supervisor’s safety liabilities. This section outlines the immediate triage steps required to secure the site and draw a hard procedural line between the previous builder's breaches and your tenure. Suspending non-compliant trades in the first 48 hours The immediate priority upon taking over a site is to formally suspend any trades who cannot produce a valid SWMS for high-risk construction work. While an incoming builder may be eager to get the project moving, pausing work limits the new PCBU's exposure to inherited risks and manages the transition of safety duties. The WHS duty a builder owes in respect of subcontractor workers on site does not wait for a new subcontract to be signed — as a person with management or control of the workplace under section 20 of the WHS Act, your duty attaches the moment those trades are working under your control. A Queensland PCBU assuming control of a construction site must verify that all high-risk construction work is supported by a valid SWMS before allowing trades to commence or continue work. For the site supervisor who is physically first on the ground, this is a first-hour task, not a first-week one: walk the site, identify every high-risk activity in progress, and stand down any trade who cannot hand you a current, signed SWMS on the spot. The supervisor's contemporaneous note of who was stood down and when becomes part of the builder's due diligence record. It is a common mistake for incoming site managers to let "minor" trades finish out the day to avoid conflict or keep the client happy. Doing so can inadvertently transfer liability for that non-compliant work directly to your company. If trades refuse to supply updated safety documentation or comply with your site rules, you may need to consider your options for terminating a construction contract or subcontract, depending on the terms of your engagement. Documenting existing site hazards before assuming PCBU control Before allowing any work to resume under your control, you must establish a clear administrative and physical baseline of the site's condition. This evidence is critical to separating the previous builder's safety breaches from your own WHS obligations as a builder in Queensland. Photograph the physical environment: Capture images of existing unsafe scaffolding, missing temporary fencing, and unprotected penetrations before any of your staff or trades touch them. Audit the paperwork: Formally record the absence of safety documentation, induction logs, and SWMS left by the previous contractor. Issue formal notices: Send written directives to all inherited trades stating that previous safety approvals are void and new SWMS must be submitted and approved before re-entry. Treat this internal stop as seriously as a regulator-issued prohibition notice or improvement notice in Queensland — if SafeWork attends and issues one, your own documented directive shows you were already managing the hazard under the WHS Act. Distinguishing Statutory WHS Liabilities from Contractual Delay Exposure When managing a distressed site takeover, you must separate your statutory duty to halt unsafe work under the WHS Act from your contractual exposure for delaying the project. While pausing the build to rectify missing SWMS or unsafe scaffolding will cause timeline pressures, statutory WHS obligations generally take priority over contractual schedules, and a contractual deadline is not a defence to a safety breach. The commercial pressure to reach practical completion quickly does not legally excuse a PCBU from their primary duty of care. Courts and tribunals do not accept contractual deadlines or client frustration as a defence to safety breaches. A builder who allows unsafe work to continue simply to avoid liquidated damages risks trading a manageable commercial dispute for a statutory prosecution. That trade is rarely rational once the figures are compared: liquidated damages on a stalled residential build typically run to a capped daily rate, whereas a Category 1 or industrial manslaughter conviction reaches into the millions and, for officers, personal imprisonment. The delay is recoverable; a conviction is not. The 2024 Category 1 Trap: Why "Negligence" Changes the Legal Threshold The days of requiring regulators to prove a builder acted with flagrant "recklessness" to secure a Category 1 conviction are over. With the introduction of the negligence standard, failing to enforce basic site safety protocols—like verifying SWMS on a site you just took over—is a statutory liability pathway that can now directly expose you to the most severe penalties under the WHS Act 2011. How the section 31 amendment removes the "recklessness" requirement Introduced by the Electrical Safety and Other Legislation Amendment Act 2024 (Qld) and commencing on 30 August 2024, the amendment fundamentally lowers the prosecution threshold by introducing "negligence" as a fault element for a Category 1 offence — a change builder operating in Queensland should treat as current law, not a proposal on the horizon. Historically, establishing this offence required proof of reckless conduct, which often proved difficult for regulators to demonstrate in complex residential building scenarios. Under the Electrical Safety and Other Legislation Amendment Act 2024 (Qld), a builder's failure to do what is reasonably practicable—within the meaning of section 18 of the WHS Act—amounting to gross negligence, may now be sufficient to trigger severe penalties. Under section 31 of the WHS Act, builders commit a Category 1 offence if they expose any individual owed a health and safety duty to a risk of death, serious injury, or illness without reasonable excuse. Courts may consider the failure to rectify an inherited site hazard as negligent conduct, which can increase the likelihood of conviction if an incident occurs. Under the 2024 amendments to the Queensland WHS Act, a Category 1 offence can be established by proving negligence, removing the previous burden of proving reckless conduct. Expanding liability to sub-trades, site visitors, and clients Expert insight: In practice, the people who get hurt on a residential takeover are rarely the roofers everyone is watching. They are the homeowner who "just popped in" to see progress, the concrete truck driver reversing up a churned-up driveway, or the client's teenage kid wandering the frame on a Saturday. These are exactly the individuals a builder assumes are someone else's problem — and exactly the ones the primary duty of care under section 19 of the WHS Act does not carve out. On a residential job, the client feels a sense of ownership over the site and will let themselves in unannounced. That is the single most common blind spot on handovers. A worker refusing to enter an unsafe zone will usually make noise about it; a roaming homeowner will walk straight under an unguarded penetration without a second thought. The primary duty under section 19(2) extends to persons other than workers, and the amended section 31 sharpens this because you no longer need to have been reckless about that visitor's safety. If you knew clients were wandering the site and took no reasonable steps — no signage, no induction, no controlled access — a failure to guard against a foreseeable visitor injury can now be framed as negligence rather than mere oversight. Tactically, the fix on day one is simple and worth documenting: lock down access with perimeter fencing and a single controlled entry point, put a standing written direction to the client that inspections happen by appointment and escorted only, and add delivery drivers to your traffic management and induction process rather than treating them as passing traffic. If you are unsure how these expanded duties impact your site handover protocols, consider obtaining advice from a WHS lawyer or Queensland building and construction lawyers. The industrial manslaughter exposure of inherited missing SWMS Example: Suppose you assume control of a residential project and allow the previous builder's roofing contractor to finish laying sheets for the afternoon without first verifying their SWMS or ensuring edge protection is compliant. If that roofer falls, your failure to halt work and verify safety documentation can be relied on as evidence of gross negligence under the new statutory framework. A fall from height builder prosecution is one of the most common enforcement scenarios in residential construction, and inheriting the hazard does not soften the regulator's approach. With 188 Australian workers losing their lives at work in 2024, regulators remain focused on site fatalities, and inheriting another builder's hazard without acting may significantly elevate your WHS prosecution risk. The numbers on conviction are not abstract: a Category 1 offence exposes an individual to a maximum penalty in the hundreds of thousands of dollars and up to five years' imprisonment, and a body corporate to a maximum in the millions—penalties being expressed in penalty units and converted to dollar figures under section 181B of the Penalties and Sentences Act 1992 (Qld) — while an industrial manslaughter conviction under Part 2A of the Work Health and Safety Act 2011 (Qld)—section 34C for a PCBU and section 34D for a senior officer—carries a maximum of 20 years' imprisonment for an individual and, for a body corporate, a maximum of 100,000 penalty units (in the order of $10 million or more, depending on the prevailing penalty unit value). Under these circumstances, courts may assess your inaction as directly exposing the worker to a risk of death or serious injury, satisfying the elements of a Category 1 or industrial manslaughter charge. The Section 272A Insurance Prohibition: Fines Paid from Your Own Pocket If you are assuming your Management Liability or D&O insurance policy will simply cover the cost of a regulatory fine if a site handover goes wrong, you are mistaken. Section 272A voids any policy purporting to indemnify you against WHS penalties, transferring the cost directly to the company — and potentially to you personally via section 272B. The statutory ban on indemnifying against WHS monetary penalties The section 272A prohibition creates three distinct offences: it is an offence, without reasonable excuse, to enter into, to provide, or to take the benefit of an insurance contract or other arrangement that purports to indemnify a person for all or part of a monetary penalty under the WHS Act, each carrying a maximum penalty of 500 penalty units. It is an offence for a builder or an individual to hold, enter into, or benefit from an insurance policy that covers monetary fines imposed under the WHS Act. This prohibition means that any existing insurance policies are void to the extent that they offer this specific cover, as reinforced by WorkSafe Queensland’s guidance on the prohibition on insurance. Why your Management Liability policy is void for regulatory fines Expert insight: The conversation with a principal usually goes the same way. They forward the broker's summary, point to the "statutory liability" or "WHS defence costs" line, and treat it as proof they are covered. What they have actually bought is a lawyer to run the defence — not a cheque to pay the fine if the defence fails. That distinction is where the pain lands. Defence costs cover keeps the meter running on your representation during the investigation and prosecution. The monetary penalty on conviction is a separate line item, and s272A voids any part of the policy that purports to pick it up. The trap is that both sit in the same policy schedule, often under headings that read as if they are one product. Principals see a healthy limit against "statutory liability" and assume the whole outcome is insured. When the penalty is handed down, they discover the insurer will fund the fight but not the fine. Two practical steps are worth taking now. Ask your broker in writing to confirm, clause by clause, which parts of the policy respond to defence costs versus any monetary penalty — and expect the penalty response to be nil or void in Queensland. And do not restructure the policy to disguise a penalty indemnity as something else, because holding or benefiting from that arrangement is itself the s272A offence. If you are uncertain about how this affects your specific coverage, it is prudent to seek advice from a commercial lawyer in Queensland. Section 272B personal liability for officers authorising prohibited cover The prohibition on insurance also creates a separate exposure channel for company executives. Under the section 272B officer liability provisions, company officers of a building company—an "officer" taking the meaning given by the Corporations Act 2001 (Cth) as applied by the dictionary to the WHS Act—can be held personally liable if they authorise or permit the company to enter into a prohibited insurance arrangement for WHS fines. As outlined in the Review of the Work Health and Safety Act 2011 Final Report, if the body corporate commits an offence against section 272A, courts may determine that directors or senior managers who permitted the conduct are also guilty of the offence. Working With a WHS Lawyer to Activate Your Due Diligence and "Reasonable Excuse" Defences Assuming control of a compromised site does not mean you are automatically guilty of the previous builder's sins—provided you act immediately. By establishing clear administrative boundaries and fulfilling your officer obligations from day one, you can map out a solid procedural mechanism for defending against regulator scrutiny. Establishing a "reasonable excuse" position against inherited safety breaches Documenting the state of an inherited site and immediately halting unsafe work serves as a critical evidence factor if the regulator intervenes. If a SafeWork Queensland builder investigation occurs shortly after you take control, comprehensive day-one documentation can help establish that any exposure occurred with "reasonable excuse", an element the prosecution must exclude under section 31 of the WHS Act. This evidence demonstrates that the hazard was pre-existing and that you were actively managing the risk according to your statutory duties. A Queensland builder may rely on the "reasonable excuse" element within section 31, together with evidence of due diligence, if they can evidence that they took all reasonable, immediate steps to rectify inherited safety hazards upon assuming site control. Meeting section 27 officer due diligence obligations on a newly taken-over site Officer duties under WHS law for builders are proactive, not passive: officers of a building company must exercise due diligence under section 27 of the WHS Act, and this duty is acute when acquiring an active project. Satisfying this obligation requires you to direct the new site supervisor to conduct an immediate safety audit, verify the licences of all inherited trades, and demand updated SWMS before allowing tools to be picked back up. Courts typically look for evidence of these immediate, system-driven actions to assess whether an officer took reasonable steps to understand and mitigate the hazards associated with the newly acquired site. Why subcontract indemnity clauses cannot shield builders from primary WHS duties Incoming builders often require existing trades to sign new subcontracts containing strong subcontract indemnity clauses designed to transfer liability. While the intended function of an indemnity clause is to protect the head contractor from a subcontractor's failures, this protection may be limited by statutory prohibitions against contracting out of WHS duties, namely section 14 (which provides that a duty cannot be transferred to another person) and section 272 of the WHS Act (which renders any term of an agreement purporting to exclude, limit or modify a WHS duty void). A subcontract indemnity might cover commercial losses or property damage, but it cannot legally transfer a PCBU's primary duty of care. If a court assesses that a builder relied on paper indemnities while failing to physically verify SWMS or site safety, the builder may still face direct prosecution under the WHS Act, rendering the contractual clause ineffective against regulatory fines or Category 1 charges. Conclusion Standing on that delayed residential build in Brisbane and watching roofers work without edge protection or valid Safe Work Method Statements might feel like a purely commercial problem left behind by the previous contractor. It is not. Under the amended Queensland WHS legislation, inheriting and ignoring another builder's safety hazard is a direct legal exposure issue. The Electrical Safety and Other Legislation Amendment Act 2024 (Qld) means that regulators no longer need to prove you were "reckless" to pursue a Category 1 offence—a failure to take reasonable care that exposes an individual to risk can now trigger negligence charges. Furthermore, the section 272A insurance prohibition ensures that if you are fined for turning a blind eye to those missing SWMS, your Management Liability policy cannot legally cover the penalty. Those fines may ultimately come directly out of your company’s capital or your personal assets. Do not let the commercial pressure of a delayed schedule dictate your safety compliance. Before any trade picks up a tool on an inherited site, formally suspend high-risk work, photograph the existing hazards, and demand updated SWMS. By drawing a hard procedural line on day one, you establish the baseline required for your section 27 due diligence defence and protect your licence from the previous builder's mistakes. FAQs What is a Category 1 offence under the Queensland WHS Act 2011? A Category 1 offence occurs when a person with a health and safety duty exposes an individual to a risk of death or serious injury without reasonable excuse. Following the Electrical Safety and Other Legislation Amendment Act 2024 (Qld), which took effect on 30 August 2024, this offence can now be triggered by negligence, rather than requiring the regulator to prove reckless conduct. This means Queensland builders may face severe penalties for failing to take reasonable care on site. Can my building company use insurance to pay for WHS fines in Queensland? No, section 272A of the Queensland WHS Act strictly prohibits entering into or benefiting from insurance policies that indemnify against monetary penalties. Policies are void to the extent they offer this cover, meaning any regulatory fines must typically be paid from company or personal assets. However, depending on the specific policy wording, insurance may still cover legal defence costs incurred during an investigation. Can company directors be personally liable if the business has prohibited WHS insurance? Yes, company officers can face personal liability under section 272B if they authorise or permit their building company to hold prohibited insurance for WHS fines. If the body corporate commits an offence under section 272A, directors who permitted the arrangement are likely to be deemed to have also committed the offence. This may create a significant personal financial risk for Queensland builder principals. Do I need a SWMS before taking over high-risk work from a previous builder? Yes, a Queensland PCBU must ensure a valid Safe Work Method Statement (SWMS) is in place before any high-risk construction work commences or resumes. Inheriting a site does not remove your primary duty of care, and allowing trades to continue without documentation may be relied on as evidence of negligence. Halting work to verify safety paperwork can help establish a due diligence defence if the regulator investigates. Will a subcontract indemnity clause protect me from WHS prosecution in Queensland? A subcontract indemnity clause cannot legally transfer a head contractor's primary statutory WHS duties to a subcontractor. While these clauses are often used to allocate commercial risk, statutory prohibitions against contracting out of safety duties severely limit their effectiveness in regulatory matters. Courts may still hold the head contractor directly liable if they fail to physically manage site safety, regardless of the paper indemnity. Does my duty of care extend to site visitors and delivery drivers? Yes, the WHS duties of a Queensland builder extend to any individual whose health and safety may be put at risk by the construction work, including visitors, clients, and delivery drivers. The Category 1 and industrial manslaughter provisions apply to exposing any owed individual to risk, not just direct employees. Builders must enforce site safety compliance strictly across all parties to effectively manage this exposure. This guide is for informational purposes only and does not constitute legal advice.

KEY TAKEAWAYS Receiving a QBCC direction under section 72 of the Queensland Building and Construction Commission Act 1991 (Qld) does not automatically establish civil liability for a failed pipeline pressure test, but failing to comply is likely to constitute a statutory offence. If third-party site machinery damaged the underground pipeline after installation, the contractor's strongest regulatory argument is generally that it would be unfair to give the direction under section 72(5) of the Queensland Building and Construction Commission Act 1991 (Qld), and that the contractor did not carry out the defective work within the meaning of section 71I — not the narrow section 74 defence, which is confined to cases where a contractor's licence details were used on a contract without authority. Merely lodging an internal review does not pause the compliance clock; pipeline contractors typically require a QCAT stay to legally suspend the enforcement of the direction. Rectifying under protest can help mitigate the risk of licence suspension, but the protest must be carefully documented to preserve potential variation claims for the repair work. You are staring at a failed hydrostatic pressure test on a newly laid sewer main, knowing your crew bedded, laid, and tested the pipe perfectly before site handover. But another trade just drove a 20-tonne excavator over the shallow trench, crushing the alignment. Now, the Queensland Building and Construction Commission (QBCC), acting under the Queensland Building and Construction Commission Act 1991 (Qld) (the Act), has sent a formal direction to rectify, dropping the problem squarely onto your lap with a ticking compliance deadline. If you ignore the notice, you risk a statutory offence, demerit points, and potential licence suspension right when your business has active pipeline contracts running across the state. But if you immediately dig up the trench and fix the pipe without a strategy, the head contractor is likely to use your compliance as proof that the defect was your fault all along, leaving you to foot the bill for someone else's damage. This article breaks down exactly how to handle the regulator's demands while legally quarantining your right to pursue commercial recovery for the repair work. The Immediate Crisis: Pause the Compliance Clock or Mobilise the Crew? With a QBCC direction sitting on your desk and the deadline approaching, your primary focus must shift from arguing over who caused the damage to managing the regulator's timeline. This section breaks down the immediate procedural levers you must pull to pause the statutory clock before you face regulatory penalties or licence suspension. Do Pipeline Operations Qualify as Regulated "Building Work" — and Do You Even Need a Licence? This question cuts two ways, depending on who you are. Licensed plumbers and drainers already know they sit squarely under the regulator, but many civil contractors wrongly assume their underground infrastructure projects fall entirely outside the jurisdiction of the Queensland Building and Construction Commission. Both assumptions can be costly. If a large pipeline or main is in fact "building work" under the Act, a civil contractor who carried it out without the appropriate licence is not just exposed to a direction to rectify — they may have been contracting unlawfully in the first place. So before you argue about who caused the failure, you need to know whether the work was regulated "building work" at all, and whether you were licensed to do it. Regulated plumbing and drainage work falls within the statutory definition of building work under Queensland law, and much civil pipeline and main work can too — which both gives the QBCC jurisdiction to issue a direction to rectify and, for an unlicensed civil contractor, may expose them to a separate unlicensed-contracting offence. This means that if a pressure test fails on work that is "building work," the regulator has authority to step in, and the same statutory mechanics apply whether the job is a major civil pipeline or a smaller plumbing and drainage installation. A licensed plumbing or drainage contractor facing a direction to rectify a defective plumbing work claim is governed by the identical section 71H to section 74 rectification framework of the QBCC Act. For plumbers and drainers, this is familiar territory: they are licensed, they are already the subject of QBCC regulation, and the rectification framework in this article applies to them directly. The critical question for them is strategic — how to respond to the direction — not whether they are captured by it. For civil contractors, there is a prior and more dangerous question. Many operators laying large pipelines or mains have never turned their mind to whether that work is "building work" requiring a QBCC licence at all. The position is not automatic in either direction. Item 11 of Schedule 1 to the Queensland Building and Construction Commission Regulation 2018 (Qld) excludes work for water reticulation systems, sewerage systems and stormwater drains from "building work" — but only where the work does not connect a particular building to a main of the system. Where a pipeline or main does connect, or is undertaken to connect, a particular building or proposed building to the main, the exclusion falls away and the work can be regulated "building work." The Queensland Supreme Court has grappled with exactly this line, holding sewer and water reticulation works on unregistered lots to be outside "building work" in one matter while treating other civil installations as caught in others. The stakes of getting this wrong are not confined to a direction to rectify. Carrying out "building work" without the appropriate licence is an offence under section 42 of the Act, and an unlicensed contractor can be left unable to recover any consideration for the work — meaning a contract can effectively be rendered void with no entitlement to payment. So a civil contractor who receives a QBCC direction over a failed pipeline may face a double exposure: the rectification demand under section 72, and the discovery that they were performing unlicensed building work all along. Where that risk is live, the first priority is often to confirm the licensing position before responding to the direction, because the two problems interact. For Queensland building and construction lawyers dealing with these disputes, the first step is therefore often to clarify two things at once: whether the specific pipeline or main is regulated "building work," and whether the contractor held the licence required to perform it — because the answers dictate both the exposure and the response. Why an Internal Review Does Not Stop the Section 73 Statutory Offence Clock Expert insight: The trap that catches contractors again and again is treating the QBCC internal review as if it buys them time. It does not. A QBCC direction to rectify specifies a compliance period on the face of the notice. Under section 72(4) of the QBCC Act, that period must be the period prescribed by regulation — in most cases 35 days under the Queensland Building and Construction Commission Regulation 2018 — unless the commission is satisfied a shorter period is warranted on safety or substantial-loss grounds. That period runs from the date of the direction rather than from the date you lodge any challenge. The compliance date on the direction keeps running while the review sits in the queue, and section 73 makes non-compliance by that date an offence in its own right — the review being "on foot" is no answer to it. Non-compliance under section 73 carries a maximum penalty of 250 penalty units (currently up to $43,175 for an individual and $215,875 for a company on prosecution), and the regulator may also apply demerit points to your licence. Separately, section 72C makes it an offence, also carrying a maximum penalty of 250 penalty units, to delay rectifying the work or to obstruct another person carrying out the rectification required by the direction. Where this bites hardest is timing. Internal review outcomes are not instant, and a contractor who waits for the result before acting can find the compliance date has already passed by the time the review is decided. By then the offence has crystallised and the demerit exposure is live, regardless of how the review ultimately lands. This matters commercially because demerit points accumulate against your licence under Part 3E of the QBCC Act. Once the commission considers that an individual has accumulated 30 demerit points in a three-year period (section 67AZD), it may cancel the licence and treat the person as not fit and proper for a term of three years for a first occasion, or for life on a second or subsequent occasion (sections 67AZF and 67AZM) — the practical end of your ability to hold pipeline contracts across the state. The practical fix is to run two tracks at once: lodge the internal review to challenge the merits, and file the Queensland Civil and Administrative Tribunal (QCAT) application together with a stay request under section 22 of the Queensland Civil and Administrative Tribunal Act 2009 (Qld) (the QCAT Act) to freeze the clock. Treat them as separate tools doing separate jobs — one attacks the direction, the other protects your position while that fight plays out. On the stay itself, the tribunal is weighing the balance of convenience and whether you have an arguable case, so give it something concrete to hold onto. In a third-party damage scenario that means front-loading the evidence that the defect may not be yours — the passed pre-handover test certificate, the handover record, and any early indication of intervening machinery damage — rather than a bare assertion that the direction is wrong. A stay is discretionary and never guaranteed, so the stronger the causation material you can put up early, the better your prospects of holding the line while the true cause is investigated. Applying for an Extension Under Section 72B to Investigate Intervening Damage If a QCAT stay is not immediately viable, another procedural mechanism is to request more time directly from the regulator. Section 72B of the Act states that a person given a direction to rectify or remedy may apply to the commission for an extension of the period for compliance. When applying for this extension to investigate intervening damage, your submission should typically include: Formal written request before expiry: The application must be submitted prior to the original compliance deadline expiring. Evidence of third-party investigation: Provide proof that you are actively seeking third-party evidence, such as pending CCTV pipeline inspection reports. Scheduling joint independent inspections: Show correspondence proving you have requested the head contractor and an independent engineer attend the site to inspect the crushed pipe. Timeline for resolution: Offer a clear, revised timeline detailing exactly when the investigation will conclude and when any necessary repair works could realistically commence. Separating Regulatory Directives from Commercial Liability for the Pipeline Failure At this stage, the head contractor is likely using the regulator's intervention as proof that you are entirely liable for the defective work under the subcontract, threatening back-charges and withholding payments. This section untangles your statutory obligation to satisfy the regulator from your commercial right to dispute financial liability for the pipe failure. Untangling Section 72 of the QBCC Act Regulatory Powers from Subcontract Defect Liability A critical point of confusion arises when contractors conflate the regulator's statutory power with their own commercial liability. Section 72 of the Act provides that the commission may direct the person who carried out the building work to rectify the building work. This is a powerful regulatory tool designed to ensure non-compliant work is fixed promptly to protect public health and safety. A QBCC direction to rectify under section 72 of the Act is a regulatory enforcement tool, which operates separately from a contractor’s civil liability for defects under a commercial subcontract. Complying with a direction to rectify defective work satisfies the regulator under the Queensland Building and Construction Commission Act 1991 (Qld) and the Queensland Building and Construction Commission Regulation 2018 (Qld), but it does not dictate who ultimately pays for that work. You can satisfy the regulatory demand to repair the pipeline while separately pursuing the head contractor for the costs if their site management caused the failure. The commercial claim runs on its own clock, and it is important not to confuse the two limitation regimes at play. On the regulatory side, section 72A(4) provides that the commission cannot give a direction to rectify more than six years and six months after the building work was completed or left in an incomplete state, unless QCAT extends that time. Separately, on the civil side, a latent defect pipeline claim can surface long after handover because underground failures are often hidden until a later inspection or failure, so the limitation period for defective work under the Limitation of Actions Act 1974 (Qld) is a live risk you must diarise the moment a dispute emerges. Satisfying the regulator quickly does not stop that commercial limitation period from running, and a recovery claim left too long can become time-barred even where the causation evidence is strong. Preserving Evidence: Demanding a Joint Independent Hydrostatic Re-Test Warning: Destroying the accident scene by prematurely excavating the failed pipeline without independent oversight is likely to severely compromise your ability to prove third-party damage. If you immediately dig up the crushed pipe, the head contractor can often argue that the failure was caused by your poor bedding or jointing techniques, and without the undisturbed site as evidence, defending against that allegation becomes exceedingly difficult. Before any rectification work begins, contractors should formally demand a joint independent hydrostatic re-test and CCTV inspection, ensuring all parties are present to document the exact location and nature of the damage. Engaging a Queensland Building and Construction Commission lawyer before you excavate can ensure the joint re-test is properly demanded, the inspection is attended by the right parties, and the evidence is captured in a form that will hold up if the head contractor later disputes causation. Resisting the Direction to Rectify Under Section 72 of the QBCC Act: When Site Machinery Causes the Pressure Drop You know your crew bedded, laid, and tested the pipe perfectly before site handover, only for another trade to run a 20-tonne excavator over the shallow trench. This section breaks down the specific legal defence available when you can prove another party is responsible for the defective state of the work, shifting the focus from your installation to their site management. The "Unfairness" Discretion Under Section 72 of the QBCC Act and the Limited Section 74 Defence If the regulator issues a direction, you are not entirely without options if the defect wasn't your fault. The common misconception is that section 74 provides a general defence of not being responsible for the defect. It does not. Section 74 is a narrow defence available only to a licensed contractor whose name, licence number or address was included on the contract or insurance notification form without the contractor's authority, and it does not assist a contractor who installed the work and later says a third party damaged it. The correct regulatory levers for a third-party damage scenario sit in section 72. Under section 72(3), the commission may take into account all the circumstances it considers reasonably relevant and is not limited to the terms of the contract; and under section 72(5), the commission is not required to give the direction if it is satisfied it would be unfair to give it. Section 71I, which defines who is taken to have "carried out" the building work, is also central, because a contractor who can show the failure resulted from intervening third-party conduct after handover may argue the defective state should not be sheeted home to them. This typically involves persuading the commission, before it decides whether to give the direction, that an intervening event broke the chain of causation after your work was completed — in plain terms, that something happened after you finished which caused the failure and severed the link back to your installation. If you can demonstrate that third-party machinery caused the failure, proportionate liability for Queensland contractors under the Civil Liability Act 2003 (Qld) becomes central to the subsequent commercial dispute over who bears the cost of the damage. Where several parties contributed to the loss — for example the contractor, the head contractor and the design engineer — they may be treated as concurrent wrongdoers, with liability apportioned between them, and a contributory negligence argument may further reduce your share where another party's conduct helped cause the defect. Proving Intervening Damage: CCTV, Trench Compaction Logs, and Site Diaries Example: Consider a scenario where a pipeline contractor finishes installing a sewer main, passes the initial pressure test, and formally hands the trench back to the head contractor. Two days later, heavy machinery traverses the alignment, crushing the pipe. To resist the direction under section 72(5) and rebut responsibility under section 71I, the contractor presents the initial successful pressure test certificate, time-stamped daily site diaries detailing the handover, and compaction logs proving the bedding met the required specifications. Furthermore, they cross-reference the Code of Practice for Excavation Work and safety protocols mandated by Workplace Health and Safety Queensland to show the head contractor failed to restrict heavy plant access over the newly backfilled trench. They then produce post-incident CCTV footage showing the pipe is crushed from above, not separated at the joints, strongly supporting the argument that intervening surface weight, rather than poor workmanship, caused the defect. In a contested matter, this documentary record is typically supported by expert evidence on the pipeline defect — an independent engineer's opinion interpreting the CCTV and failure mode — which carries far more weight than the contractor's own assertion about how the pipe failed. The Subcontractor's Dilemma: Flawed Engineering Designs vs. Execution Failures Expert insight: Not every failed pressure test comes down to physical damage. Sometimes the pipe was built exactly to the drawing, and the drawing was the problem. An argument that the failure traces to a defective design rather than defective installation can reach these cases, but the evidentiary bar is higher than contractors expect, because "I only did what I was told" is easy to assert and hard to prove after the fact. The distinction that matters is between installing to a defective design and installing defectively. If the workmanship is sound and the failure traces back to the design — inadequate grades, wrong bedding specification, undersized pipe — then the argument that the failure was not caused by your workmanship has real teeth. If the install itself was sloppy, no amount of design blame will save it. What tends to carry weight is a contemporaneous paper trail, not a reconstruction built once the dispute is running. A request for information querying the design, a written response or site instruction directing the subcontractor to build it as drawn, and a dated record of the concern being raised before the pipe went in are far more persuasive than a statement prepared for the hearing. The common failure is the verbal warning. Contractors routinely raise design doubts on site, in the shed, or over the phone, and none of it survives if it was never put in writing. If you flagged a design concern and the head contractor waved you on, get that exchange into an email or an RFI the same day — that document is often the difference between wearing the direction and shifting it back up the chain. Bear in mind that even a strong position resisting the direction on the regulatory front does not automatically resolve who pays commercially. The design responsibility question, and where it sits under the subcontract, is a separate fight that runs alongside the QCAT process rather than being decided by it. Executing "Rectification Under Protest" to Secure Future Variation Claims If QCAT refuses a stay, or if commercial realities dictate that you must fix the pipe immediately to keep the project moving, you face a critical choice. This section explains how to mobilise your crew to perform the repairs while legally quarantining your right to claim the costs back from the party who actually caused the damage. The Legal Mechanics of Responding "Under Protest" Without Admitting Fault When faced with an immovable regulatory deadline and a head contractor who refuses to concede fault, contractors often feel trapped between risking their licence and paying for someone else's mistake. In these scenarios, proceeding "under protest" is a critical strategic tool, but it requires highly precise communication to ensure the head contractor cannot argue that your willingness to repair the pipe is an admission of defective workmanship. Rectifying defective pipeline work "under protest" in Queensland involves complying with a statutory direction to avoid regulatory penalties, while formally reserving all contractual rights to pursue compensation for the repair work. Executing this strategy successfully allows you to comply under protest or seek a QCAT stay while keeping your commercial claim alive. The written communication must explicitly separate your regulatory compliance from your contractual obligations. Drafting the Notice: Reserving Rights for Quantum Meruit and Variation Recovery Before mobilising your crew to dig up the crushed sewer main, you must issue a formal "Notice of Rectification Under Protest" to the head contractor. A variation clause is designed to provide a structured mechanism for a contractor to claim additional payment for changes in the scope of work. However, the enforceability of this clause depends heavily on the contractor issuing the correct notices at the correct time. Because these clauses are conditional, their effectiveness turns on strict compliance with time-bar notice periods. Your notice should typically include: Explicit purpose of work: A clear statement that the excavation and repair works are being performed strictly to mitigate regulatory risk under the QBCC direction, and not as an admission of civil liability for the defect. Invocation of the variation clause: A formal notification under the subcontract's variation provisions, treating the repair work as a directed change in scope. Framing the repair as outside your original scope of works turns a potential scope of works dispute to your advantage and guards against the head contractor later characterising the work as an unapproved variation you must absorb. Reservation of equitable rights: A documented reservation of your right to pursue a variation claim or seek reasonable remuneration for construction work under quantum meruit principles once the repair is complete. Notice of delay: A formal warning that the repair works may impact the critical path of the project, establishing grounds for a potential extension of time claim. Navigating Back-Charges When the Head Contractor Rectifies the Pipeline Warning: Outright refusing to rectify the pipeline without first securing a QCAT stay can expose your business to severe financial retaliation. If you abandon the defective work, the head contractor is likely to step in, engage a third party to perform the repairs, and deduct those costs from your next progress payment. These deductions often manifest as an inflated rectification cost dispute, forcing you onto the defensive in a complex security of payment battle. Where the head contractor withholds or back-charges against a certified amount, your fastest route to recovering cash flow is often a payment claim and adjudication application under Chapter 3 of the Building Industry Fairness (Security of Payment) Act 2017 (Qld), which runs on strict statutory timeframes of its own. If you find yourself facing imminent back-charges while trying to navigate a regulatory direction, you should obtain advice from a construction lawyer to assess your options for preserving cash flow. Conclusion That crushed sewer main and the ticking compliance deadline on the regulator's letterhead do not have to dictate a complete commercial loss for your business. By understanding the distinct boundary between a statutory direction and your subcontract liability, you can strategically navigate the crisis without unnecessarily forfeiting your right to payment. You now know that an internal review will not pause the statutory offence clock on its own, and that resisting a direction on the basis of third-party damage — through the unfairness discretion in section 72(5) — requires meticulous evidence preservation. More importantly, you understand how to execute repair works under protest to satisfy the regulator while keeping your variation claims alive. The two things that decide these matters — the compliance clock and the undisturbed evidence in the trench — are both lost by waiting. Before the compliance date passes or a single piece of machinery breaks ground, the notice of rectification under protest and the demand for a joint independent inspection need to be drafted and served. Merlo Law acts for Queensland pipeline and civil contractors in exactly these situations: contact us to have your protest notice, stay strategy and evidence-preservation demands prepared while there is still time to protect both your licence and your right to recover the cost. FAQs Does a QBCC direction to rectify mean I am legally at fault for the pipeline defect? No, a direction under section 72 does not automatically establish civil liability under your subcontract. It is a regulatory enforcement tool used to ensure non-compliant work is addressed, which operates separately from determining who bears the ultimate financial responsibility for the damage. Can I just lodge an internal review with the QBCC to stop the compliance deadline? No, lodging an internal review does not pause the statutory clock under section 73 of the Act. To legally suspend the enforcement of the direction and mitigate the risk of a statutory offence, contractors typically need to file a concurrent application to QCAT for a formal stay. How do I resist a direction to rectify when a third party caused the failure? Section 74 is a narrow defence confined to cases where a contractor's licence details were used on a contract without authority, so it will not usually assist a third-party damage scenario. The correct approach is to persuade the commission, before it decides whether to give the direction, that it would be unfair to give it under section 72(5), supported by evidence that an intervening event, such as a head contractor's heavy machinery driving over a backfilled trench, caused the pipeline to fail after installation. How do I rectify pipeline work under protest in Queensland? Rectifying under protest involves complying with a statutory direction to avoid regulatory penalties, while formally reserving all contractual rights to pursue compensation. This typically requires issuing a precise written notice to the head contractor before commencing repair work, explicitly stating that the repairs are not an admission of liability. Will a variation clause protect me if I fix the damaged pipe? A variation clause is designed to provide a mechanism to claim additional payment for scope changes, but it does not offer absolute protection. The enforceability of this clause depends heavily on strict compliance with notice periods, meaning failure to submit your claim on time can result in forfeiture of the payment. What happens if I ignore the QBCC direction without a QCAT stay? Failing to comply with a direction to rectify without a valid extension or a QCAT stay is likely to constitute a statutory offence. The consequences can include severe regulatory penalties, accumulation of demerit points, and potential suspension or cancellation of your contractor licence.

Key Takeaways Suing is worth it only if the judgment can be turned into money. Check the counterparty's assets, security and insurance before the statement of claim is filed, not after judgment. Value the claim on a recovery-adjusted basis. Start with the likely award, take off the costs you will not get back, then discount for the chance of actually collecting. Costs ordered on the ordinary basis are usually less than what you pay your own lawyers. Look beyond the builder company itself. Recovery often comes from retention, bank guarantees, personal guarantees, insurers, money the builder is owed on other projects, or (for residential work) the Home Building Compensation Fund. Litigation may be the wrong first step if something faster reaches the same money. That includes security of payment adjudication, recourse to security you already hold, or a statutory demand on a genuinely undisputed debt. The builder has gone quiet. The defects report is in, the rectification quote is bigger than the retention you hold, and someone has said it: we should sue. The real question is not whether you would win. It is whether construction litigation in NSW would put money back in your account. That depends on four things: proof, a reachable source of payment, a margin after costs, and no faster tool reaching the same money. If any one of those fails, you are likely to pay for a judgment rather than a recovery. This article is for directors, principals and commercial managers of NSW businesses weighing commercial disputes with a builder, subcontractor or other counterparty. The procedure behind each step is covered in our guide to commercial litigation in NSW. Is it worth suing a builder in NSW? The short answer Suing is worth it when the expected recovery is still higher than what negotiation, security you already hold, or a statutory shortcut would deliver, even after you allow for costs you won't get back and the risk of not being paid. It is usually not worth suing yet in three situations: the builder has no reachable assets and no guarantor, insurer or upstream money behind it the claim depends on witnesses who have left and records that no longer exist a limitation period or contractual time bar has already run Commercial litigation in NSW commonly takes between twelve months and three years from commencement to judgment. A builder that is struggling today is rarely in better shape by the end of that period. Delay favours the party that does not intend to pay. The four gates to clear before construction litigation in NSW Gate 1: Can you prove each element from records you already hold? Breach of contract claims require a binding contract, the relevant term, a breach, and loss caused by that breach. Each element needs a document: the instruction, the inspection report, the photographs, the cost of rectification. If the case relies on a site supervisor who has left the industry, discount it. Check the clocks as well: Most contract and tort claims must be brought within six years from accrual under s 14 of the Limitation Act 1969 (NSW). Residential statutory warranty claims run for six years for a major defect and two years otherwise, under s 18E of the Home Building Act 1989 (NSW). A contractual notice clause may already have closed the claim. Gate 2: Is there money at the end, and where exactly? Run the searches before you send the letter of demand: an ASIC company search, which shows status, directors and former names, and can reveal phoenix patterns insolvency notices and court lists a Personal Property Securities Register (PPSR) search title searches a bankruptcy search, if a director gave a personal guarantee You are looking for a named source of payment you can actually reach, not a general sense that the builder "does big jobs". Practice note: In construction, the asset that most often pays a judgment is not the builder's plant or land. Plant is usually financed and land is usually mortgaged. The asset that pays is money principals owe the builder on other live projects, which can be reached with a garnishee order after judgment. If you cannot name who owes the builder money, you have not answered Gate 2. Gate 3: Does the margin survive costs and time? The court's power to award costs is in s 98 of the Civil Procedure Act 2005 (NSW), and costs ordinarily follow the event under r 42.1 of the Uniform Civil Procedure Rules 2005 (NSW) (UCPR). But costs assessed on the ordinary basis only approximate the reasonable cost of work reasonably required, and they are usually less than what you actually pay. You carry that gap. Expert fees on defects, delay and quantum rise with technical complexity, not with the size of the claim. Security for costs works against claimants that look unable to pay an adverse costs order (r 42.21 of the UCPR; s 1335 of the Corporations Act 2001 (Cth) (Corporations Act)). If you are suing a builder that is already failing, there is no equivalent protection for your own costs. The forum also affects the margin: Local Court: General Division to $100,000 Small Claims Division to $20,000, with very limited costs District Court: To $1,250,000 NCAT: Home building claims to $500,000 (s 48K of the Home Building Act 1989 (NSW)), with restricted costs Supreme Court: No limit Gate 4: Is there a faster tool for the same money? If you are owed a progress payment, adjudication under the Building and Construction Industry Security of Payment Act 1999 (NSW) runs on business days, not court lists. The respondent generally has 5 business days after receiving the application to respond (s 20(1)), the adjudicator generally has 10 business days after that to decide (s 21(3)), and the adjudicated amount is payable within 5 business days of service (s 23). If it goes unpaid, the adjudication certificate can be filed as a judgment debt (ss 24–25), often within days. Adjudication fees are governed by s 29, and if the claimant pays the respondent's share and is not reimbursed, that amount can be added to the certificate (s 24(5)). The determination is interim (s 32), and the window to apply is generally only 10 or 20 business days (s 17(3)), so take early security of payment advice. If you hold retention or a bank guarantee, the contract may let you have recourse to it without going to court. If the debt is liquidated and undisputed, a statutory demand under s 459E of the Corporations Act requires the company to pay, secure or compound within 21 days, or face a presumption of insolvency. Warning: Do not issue a statutory demand to pressure a builder over a live defects or variation dispute. A demand is an insolvency tool, not a collection letter. On a genuinely disputed debt it is likely to be set aside under s 459G of the Corporations Act, with costs against you. See our guide to statutory demands in NSW construction. Where recovery actually comes from Source What to check first NSW mechanism Retention or bank guarantee you hold The recourse clause; whether the guarantee is unconditional Contractual recourse, without a court if the clause permits Money owed to the builder on other projects Who the builder's principals are Garnishee order after judgment You are a subcontractor; the principal owes your contractor Debt certificate and notice of claim Contractors Debts Act 1997 (NSW), ss 5–7 A director's personal guarantee Signed guarantee; the guarantor's assets Judgment against the guarantor; bankruptcy notice (requires a judgment of at least $10,000) A developer or head contractor responsible for the whole of the works Whether the defects arise from delegated work ss 37 and 39 of the Design and Building Practitioners Act 2020 (NSW) (DBP Act). See Pafburn Pty Limited v The Owners – Strata Plan No 84674 [2024] HCA 49 The builder's liability insurer Policy type; notification s 4 of the Civil Liability (Third Party Claims Against Insurers) Act 2017 (NSW) (Third Party Claims Act) Home Building Compensation Fund (residential work) Whether a certificate was issued Fund claim with its own notice requirements. See our Home Building Compensation Fund guide Pafburn matters for recovery as well as liability. In Pafburn, a 4:3 majority of the High Court held that a party responsible for the construction work as a whole cannot use proportionate liability to shift loss from work it delegated. So an owner can usually pursue the solvent head contractor or developer for the whole of that loss, rather than chasing each subcontractor. Our guide to the statutory duty of care after Pafburn explains who owes the duty and where apportionment can still be pleaded. The Building (Approvals and Practitioners) Act 2026 (NSW) (BAP Act) was assented to on 14 August 2026. It will repeal the DBP Act and carry both the statutory duty and the non-delegable duty rule into Part 8 of the BAP Act (ss 179 and 181) from dates still to be proclaimed. In Parliament, the Government said the Bill seeks to uphold the existing operation, application and interpretation of the duty, which indicates an intention not to disturb Pafburn. The BAP Act does not itself say how causes of action that have already accrued under s 37 of the DBP Act will be treated. Schedule 1 leaves savings and transitional arrangements to regulations, which may be made up to two years after the relevant provision commences. As at 1 October 2026, Part 8 of the BAP Act has not commenced and s 37 of the DBP Act remains in force. Confirm which provisions are in force, and whether any transitional regulations have been made, when you assess the claim. Claims against directors for insolvent trading under s 588G of the Corporations Act are ordinarily brought by a liquidator, and directors may rely on the safe harbour in s 588GA. Treat them as a possibility, not a plan. Practice note: Budget for enforcement Budget for enforcement as part of the claim. After judgment, an examination tells you where the money is and a garnishee order takes it. Businesses that budget only up to judgment often stop at exactly the point where the recovery work begins. When the answer is no A "no" at Gate 2 or Gate 3 does not mean giving up the claim. It means not paying for court proceedings yet. The options are: Preserve the evidence and monitor the counterparty's solvency, while keeping track of the limitation clock. Negotiate from leverage, using a properly framed offer of compromise or Calderbank offer, so that rejecting it carries costs consequences. If the builder enters liquidation, lodge a proof of debt. Be careful with recent payments from a failing builder. A liquidator may recover them as unfair preferences under ss 588FA, 588FE and 588FF of the Corporations Act. What to ask a lawyer to quantify before you file Ask for three figures in writing: the realistic award, not the amount claimed the costs you won't get back, to judgment and through enforcement the chance of collecting, after other creditors are accounted for Also ask which forum fits and what the single next step is. Bring the contract and its amendments, the dispute correspondence, the project records, your search results and a short chronology. Conclusion A judgment is a means to an end. Before you sue a builder or counterparty in NSW, clear the four gates: proof, a reachable source of payment, a margin after costs, and no faster tool. If the answer is still unclear, have an independent litigation lawyer in NSW test those figures against your file before anything is filed. This guide states the law in New South Wales as at 1 October 2026. FAQ Is construction litigation in NSW worth it if the builder has no assets? Usually not against the company alone. Check for guarantors, insurers, security you hold and money owed to the builder on other projects. If none of these exist, preserve the claim and monitor the builder. How do I check whether a builder can pay a judgment in NSW? Use ASIC, PPSR, title, insolvency-notice and court-list searches, plus a bankruptcy search for any guarantor. After judgment, an examination order can compel disclosure of the builder's finances. Should I use security of payment instead of suing a builder in NSW? If the claim is for a progress payment under a construction contract, adjudication is usually faster: a straightforward application commonly runs to an enforceable determination within weeks. It is interim and does not finally decide the parties' contractual rights. Can I claim directly against a builder's insurer in NSW? The Third Party Claims Act allows a claimant, in defined circumstances, to recover from the insurer of an insured person who has an insured liability. Get advice on whether those circumstances apply to you. What happens if the builder goes into liquidation after I sue in NSW? A stay generally stops the proceedings from continuing without the court's leave. You will usually lodge a proof of debt and rank as an unsecured creditor.

Last reviewed: 30 September 2026. Jurisdiction: New South Wales, Australia. Currency note: Two NSW Acts that received assent on 14 August 2026 are relevant to this guide, but neither has yet changed the rules it applies. The detail is in the currency notes panel at the end of this guide. Key takeaways An extension of time buys time, not money. An extension of time (EOT) claim in a NSW construction contract protects the contractor against liquidated damages (LDs). It does not pay the contractor anything. Delay costs need their own contractual entitlement (a delay-costs clause or a variation) or a damages claim for breach. The notice window usually decides the file. Under Turner Corporation Pty Ltd (Receiver & Manager Appointed) v Austotel Pty Ltd (1994) 13 BCL 378, a contractor that had a contractual route to an EOT and did not use it cannot fall back on the prevention principle. The notice period runs from the delay event, not from the day the LDs arrive. The reserve power cuts both ways. Peninsula Balmain Pty Ltd v Abigroup Contractors Pty Ltd [2002] NSWCA 211; (2002) 18 BCL 322 (Hodgson JA; Mason P and Stein JA agreeing) and Probuild Constructions (Aust) Pty Ltd v DDI Group Pty Ltd [2017] NSWCA 151 generally require a superintendent or head contractor holding a unilateral power to use it for principal-caused delay. But "absolute discretion, no obligation to consider" drafting excluded that duty in Growthbuilt Pty Ltd v Modern Touch Marble & Granite Pty Ltd [2021] NSWSC 290. Delay claims are often lost on process rather than merits. The usual causes are a late notice, no critical-path evidence, a global claim with no link between cost and cause, or acceleration on a verbal instruction. The record made on site in the week of the event is the evidence that decides the claim. The ten most common ways claims are lost are collected in the failure-mode library near the end of this guide. If you are short of time, read that first. Table of Contents Which situation are you in? The same delay reaches you from one of several positions, and each asks a different first question. Find yours, go to the section listed, then read the matching scenario near the end of this guide. You are… Your first question Start at Matching scenario A contractor seeking time Is there a qualifying cause, and was the notice given in time? The sections on the contractual entitlement and on notices and time bars Scenario 1 A principal or superintendent assessing a claim Must I extend time, even without a compliant claim? The sections on superintendent duties and on proving delay Scenario 1 A contractor seeking money for delay Where does the entitlement to delay costs come from? The section on money for time Scenario 3 A subcontractor or head contractor in the chain Does the head-contract time regime flow down, and on what windows? The section on delay down the chain Scenario 2 A contractor who has already missed a notice window Is there still a route to time, or a reason the time bar has not operated? The sections on waiver and estoppel and on superintendent duties, then the steps for a missed window Scenario 1 A residential builder or owner How does the contract's EOT regime sit with the statutory timing warranty? The section on residential building work Scenario 4 Introduction A principal who causes delay on a NSW job may still be entitled to deduct liquidated damages for that period if the contractor did not use its notice, its program and the contract's reserve power in the right order. Take an AS 4000 warehouse. The principal's design information arrives late, and the contractor's crew stands down while it waits. Everyone on site knows why the job is behind. The contractor's contracts administrator means to "put the EOT in at the end". The contractual notice window closes. The superintendent declines to extend time, and the principal starts deducting liquidated damages. The contractor's answer is the prevention principle. The principal's answer is Turner v Austotel. This is the ordinary shape of an extension of time claim in NSW construction, and it is decided by process far more often than by who caused the delay. The exposure reaches the whole industry. Head contractors carry it upward to developers and government principals, and pass it downward to trades. Superintendents carry it in a dual role that the courts police. Site supervisors create, or fail to create, the diary and program record that later becomes the only evidence. On many commercial jobs the accumulated liquidated damages are among the largest numbers in dispute, and the question underneath them is time. The area is harder than it looks because three layers run on the same days. The contract sets qualifying causes, notice windows and a reserve power. The common law adds the prevention principle and time at large, and NSW courts have spent three decades working out how far a contract can shape or exclude them. Statute runs its own clocks alongside. The Building and Construction Industry Security of Payment Act 1999 (NSW) ("SOP Act") sets the payment-claim period in section 13(4), the due date in section 11, the payment schedule deadline in section 14(4) and the statutory-suspension requirements in section 27. The Home Building Act 1989 (NSW) ("HBA") adds its timing warranty, and limitation periods run in the background. None of these waits for an EOT assessment. This guide works through the file in the order it arises. It covers what delay and disruption claims are, the NSW prevention line, the contractual entitlement, notices and time bars, how the superintendent assesses, how delay is proved, how money for time is recovered, delay down the subcontract chain, and where these claims are decided. It closes with drafting checklists, four NSW scenarios and a failure-mode library. As at 30 September 2026, two currency points apply, both set out in the currency notes panel at the end of this guide. In short, the Building (Approvals and Practitioners) Act 2026 (NSW) ("BAP Act") has received assent but section 202 has not commenced, and the in-force SOP Act still uses “business days”. Before counting a statutory deadline, check whether the enacted label change has commenced. What delay and disruption claims are in a NSW construction contract "Delay claim" is used loosely on site for four different claims, and each is won or lost on different evidence. This section separates them and routes the principal's side of the same delay to its own guide. Delay, disruption, prolongation and acceleration: four different claims Four claims come out of a late job, and conceding the wrong one is how contractors lose money they were owed. Delay is late completion. The work reaches practical completion after the date for practical completion, and the question is whether that date should move. The contractual tool is the EOT. Its main legal function is to protect the contractor from liquidated damages and to keep the principal's LD regime alive by separating out delay the principal caused. Disruption is lost productivity. The contractor works less efficiently because of out-of-sequence instructions, stacked trades, restricted access or piecemeal design release. Disruption may push completion out, or it may not. A contractor can be disrupted and still finish on time by spending more. That is why disruption is a money claim, not a time claim, and why it is proved by productivity evidence, not by a program. Prolongation is the time-related cost of being on site longer: site overheads, supervision, plant, site sheds and preliminaries that run by the week. It usually follows an EOT but is not created by one. Acceleration is the cost of recovering time. That cost may be incurred because the principal directed it, because the principal wrongly refused a valid EOT and left the contractor facing LDs, or because the contractor chose to catch up on its own account. Each claim asks the same three questions: is there an entitlement to time, is there an entitlement to money, and who caused it? The answers do not travel together. An EOT for inclement weather above the allowance usually carries time and no money. A principal-caused delay can carry both. A disruption claim can carry money and no time. Site shorthand, and the habit of bundling delay and variation claims together in correspondence, hides these differences. The rest of this guide keeps them apart. The single most expensive assumption in this area is that an EOT is an entitlement to money. It is not. Whether delay costs follow depends on a separate clause, discussed in the section on money for time. Where liquidated damages in New South Wales construction fit The contractor's EOT and the principal's liquidated damages are two sides of the same delay, but they are covered in separate guides for a reason. Liquidated damages are the principal's pre-agreed remedy for late completion, running from the date for practical completion as adjusted by any EOT. Every day of extension granted is a day of LDs lost. That is why principals resist EOTs, and why the prevention principle, discussed next, exists. How the LD rate is set, whether it is a penalty under Paciocco, whether a $1 or nil rate leaves general damages open, and how LDs are levied through set-off and security are all covered in our guide to liquidated damages in NSW construction contracts. This guide takes the other side. It asks when the contractor is entitled to more time, what happens when the machinery for giving time fails, and when a contractor can be released from a completion date altogether. Our liquidated damages guide has its own short treatment of prevention, written from the levy side. The treatment below is the canonical one and is written for the party who needs the time. The prevention principle in NSW: rationale, reach and limits This is where most delay analysis goes wrong. Contractors treat the prevention principle as a general fairness rule that rescues any principal-caused delay, and the NSW cases say something narrower and more useful. The four subsections below trace what "prevention" means, when it fails, when it can be contracted out, and what time at large actually delivers. From the prevention principle to Spiers Earthworks: what "prevention" means The doctrine is older than the standard forms, and the order of development explains its current shape. If a contract has no mechanism to extend time for the principal's own delay, the principal cannot hold the contractor to the original date and so cannot recover liquidated damages. With no date to measure against, time is "at large". That is why every modern standard form includes an EOT clause for principal-caused delay: the clause exists partly to protect the principal's LD regime from prevention. The Western Australian Court of Appeal gave the principle its modern Australian framing in Spiers Earthworks Pty Ltd v Landtec Projects Corporation Pty Ltd (No 2) [2012] WASCA 53. This is also persuasive in NSW. A party cannot insist on performance of an obligation that it has itself caused the other party not to perform. McLure P observed that the principle may be a manifestation of the duty to cooperate implied by law into contracts. That observation matters in NSW because the Court of Appeal adopted it. In Probuild Constructions (Aust) Pty Ltd v DDI Group Pty Ltd [2017] NSWCA 151, McColl JA (Beazley ACJ and Macfarlan JA agreeing) explained the principle by reference to McLure P's reasoning. Prevention is a rule of construction and cooperation, not a free-standing equitable discretion to excuse late contractors. In NSW, Turner Corp Ltd v Co-ordinated Industries Pty Ltd (1994) 11 BCL 202 gives three considerations that keep the principle in proportion: If the EOT clause covers delay caused by the principal's breach or act, time is not set at large merely because the principal delayed. The contract has already provided for it. Otherwise, the contractor must show actual delay to completion caused by the principal's conduct. Conduct that could have delayed the works, but did not, is not prevention. The court looks at the overall effect. A small principal delay does not wipe out a large period of the contractor's own delay. Taken together, prevention protects a contractor from being held to a date the principal made impossible. It does not reward a contractor that had a contractual route to more time and did not use it. The next subsection turns on that distinction. Turner v Austotel: why a contractor who fails to claim is not "prevented" The practical consequence of the NSW line is blunt. The notice you chose not to give is rarely rescued later. In Turner Corporation Pty Ltd (Receiver & Manager Appointed) v Austotel Pty Ltd (1994) 13 BCL 378, Cole J said that where the contract provides a mechanism for extending time in respect of the relevant principal-caused delay, a contractor cannot rely on the prevention principle where it failed to exercise a contractual right that would have negated the effect of that delay. The builder argued that late instructions regarding a gas detector prevented completion, but it had claimed and obtained a seven-day EOT arising from that same event. Having received the contractual adjustment to the date for practical completion, it could not also rely on prevention to place time at large. The contract gave the builder a way to have the date moved. Cole J went further: a builder that has a right to claim an extension and fails to do so cannot claim that the principal's act of prevention excused it. That statement is generally treated as obiter, but NSW courts and commentators consistently apply it. On that reasoning, it is the contractor's own failure to use the contractual route, not the principal's conduct, that leaves it bound to the date for practical completion. The principal is not taking advantage of its own wrong. It is holding the contractor to machinery the contractor agreed to. The contrasting approach is Gaymark Investments Pty Ltd v Walter Construction Group Ltd [1999] NTSC 143; (1999) 16 BCL 449, a Northern Territory decision arising from an application for leave to appeal from an arbitral award. There, the contractor had not complied with the contractual notice requirements. However, the contract had also been amended to remove the superintendent's discretionary reserve power to grant an extension of time despite non-compliance. Bailey J upheld the arbitrator's conclusion that, in those circumstances, there was no contractual mechanism capable of extending time for principal-caused delay and the prevention principle defeated the principal's liquidated damages claim. Gaymark has been widely criticised in subsequent commentary, and NSW decisions have generally preferred the Turner v Austotel approach. It is persuasive authority from another jurisdiction and should not be cited to a NSW court as though it stated local law. Two qualifications keep Turner v Austotel from becoming absolute. First, it assumes the contractor could have claimed. If the EOT clause does not cover the relevant principal act, the contractor had no route and time may be put at large (see the section on time at large, below). Second, the NSW reserve-power cases (see the section on superintendent duties) may require the superintendent or head contractor to extend time for principal-caused delay even without a compliant claim. That is a contractual route to time, not a prevention defence, and it depends on the drafting. Warning: Prevention rarely rescues a notice you chose not to give. If your contract gives you an EOT route for the principal's delay and you let the window close, assume in NSW that the prevention principle will not save you. Your remaining arguments are waiver or estoppel (see the section on waiver and estoppel) and the reserve power (see the section on superintendent duties), and both depend on facts you will have to prove. If you have already missed a window, start with the steps under "If you have already missed the window", later in this guide. Then send Merlo Law the contract, the delay register and the correspondence around the event, and we can assess whether a reserve-power request or a waiver or estoppel argument is still open. Contracting out: Probuild, Growthbuilt and "absolute discretion" On a typical NSW standard form, prevention is preserved through the reserve power. On a heavily amended subcontract, it can be excluded altogether. The words decide which. Probuild confirms that prevention can be modified or excluded by contract. The principle is not a mandatory rule. It gives way to clear drafting, so whether it survives in your contract is a question of interpretation, and a risk that should be priced at tender. Growthbuilt Pty Ltd v Modern Touch Marble & Granite Pty Ltd [2021] NSWSC 290 shows what clear drafting looks like. The subcontract gave the head contractor an "absolute discretion" to extend time. It also said expressly that the head contractor had no obligation to extend time or even to consider doing so. Henry J held that these words left no room for an implied obligation of reasonableness or good faith in exercising the power. The parties had contracted out of the duty recognised in Probuild by expressly providing that the head contractor had no obligation to exercise or even consider the power to extend time. The subcontractor had not claimed an EOT under the subcontract's EOT clause, so its prevention defence failed. The court also held that the LD rate was not a penalty. Growthbuilt is a first-instance decision, and the drafting was unusually explicit. The safe reading is not that "absolute discretion" alone always excludes prevention. It is that absolute discretion combined with an express statement that there is no obligation to exercise or consider the power was enough on those facts. Decision path: has the clause excluded or preserved prevention? Step Question If yes If no 1 Does the EOT clause cover the principal's (or head contractor's) acts, omissions and breaches, including through a catch-all? Go to step 2 The contractor had no route to time for that delay. Time may be put at large (see the section on time at large) 2 Did the contractor make a compliant EOT claim within the contractual notice period? Assess the claim on its merits (see the sections on the contractual entitlement and on proving delay) Go to step 3 3 Is there a reserve (unilateral) power to extend time? Go to step 4 Turner v Austotel is likely to bind the contractor to the date, subject to waiver or estoppel 4 Is the power held by an independent certifier with an express duty to act honestly and fairly, or by a party? Certifier: Peninsula Balmain reasoning. Party: Probuild reasoning (see the section on superintendent duties) — 5 Does the clause say the power is at "absolute discretion" and that there is no obligation to exercise or consider it? Growthbuilt: prevention is likely excluded A duty to extend for principal-caused delay is likely implied Run the table on the executed contract, including every special condition. The words that decide step 5 are often in an annexure no one on site has read. Time at large: what it gives the contractor and what it does not Time at large gives the contractor two things and takes away one. When prevention applies and the contract has no working mechanism to extend time for it, the completion date falls away. The contractor's obligation becomes to complete within a reasonable time, assessed in all the circumstances, including the principal's delay. First, the liquidated damages machinery falls away with the date, because there is no date to measure LDs from, so the contractor avoids the daily rate for the period it covers. Second, the contractor gains leverage in the final account. What it takes away is certainty. It does not free the contractor from liability for delay. If the contractor then fails to complete within a reasonable time, the principal may still recover general damages for delay beyond that time, proved in the ordinary way. That can be a bigger number than the capped LD rate the contractor escaped. Time at large is a defence to a levy, not an amnesty. Time at large is also sometimes pressed into service in termination of construction contract disputes, as a basis for arguing that a principal could not rely on the contractor's lateness to terminate. That is a separate and high-stakes decision, and so is suspending work in response to non-payment. Neither is treated here. If suspension or termination is on the table, start with our analysis of suspending or terminating unpaid NSW pipeline contracts and get advice before acting.

Three things make up the entitlement: a qualifying cause, a compliant claim, and proof of critical delay. Each depends on the standard form in use and how it has been amended. This section maps the first two against the NSW standard forms. Proof is covered in the section on proving delay. An EOT claim has a familiar anatomy regardless of form. It identifies the delay event and the date it began. It identifies the qualifying cause it falls under. It shows that the event delayed the work on the critical path to practical completion, not just some work. It states the days claimed. It attaches the program or delay analysis that supports those days. Many forms add that the contractor must have taken reasonable steps to mitigate, and that the delay was not caused by the contractor's own default. A claim missing any element gives the assessor a reason to reject it, and on many forms a rejected claim cannot be resubmitted once the window has closed. Qualifying causes of delay, including weather and neutral events Most claims that fail on entitlement fail here: the contractor proves delay, then finds the cause is not on the list. A qualifying cause is one the contract says entitles the contractor to more time. Typical lists include: acts, omissions, defaults or breaches of the principal, the superintendent or the principal's other contractors variations latent conditions industrial action not specific to the contractor inclement weather above a stated allowance of days force majeure or events outside both parties' control a catch-all such as "any other act, default or omission of the principal" Some causes are "neutral". They are neither party's fault, and the contract may give time without money (weather, force majeure). Others are principal-risk events that may carry both. The catch-all matters more than it looks, for prevention reasons. If a principal's act falls outside every listed cause and there is no catch-all, the contractor has no contractual route to time for it. Time may be put at large. A well-drafted catch-all protects the principal's LD regime. A narrowed or deleted one exposes it. Principals who strike the catch-all to reduce EOT exposure can, without realising it, reopen the prevention argument they were trying to close. Weather clauses need precise reading. The allowance may be stated in days, by month, by reference to Bureau of Meteorology records, or by a site-specific test of when work is "prevented". Contractors should record in the site diary each day lost, why it was lost and what work was affected. They should not rely on rainfall totals alone. The EOT regime ends at practical completion. Delay after that date does not generate liquidated damages, because the obligation LDs secure has been performed. Obligations during the defects liability period are a separate regime: the contractor's duty to rectify defects runs on its own terms and is not an extension of the completion obligation. Practical completion ends the time dispute. It does not end the relationship. Latent conditions in construction as a delay event The notice given on the day a latent condition is discovered usually controls both the time claim and the cost claim. Latent conditions are physical conditions on or near the site that differ materially from what a competent contractor could have anticipated at tender, such as rock, groundwater, contamination or buried services. Whether they are a qualifying cause of delay depends entirely on the risk allocation. Many standard forms treat them as a principal-risk event, subject to notice. Many amended and design and construct contracts shift the risk to the contractor through site-investigation warranties or reliance disclaimers. Contamination also carries a separate regulatory layer, including notification duties and clean-up exposure. Where latent conditions are a qualifying cause, the contractor usually has two separate claims with two separate procedures. One is a cost claim, often valued as a variation. The other is a time claim through the EOT clause. The notice for the cost claim is frequently required "promptly" or within the period required by the contract after discovery, before the condition is disturbed. The EOT notice may run on a different window. Satisfying one does not always satisfy the other. A single well-drafted notice that identifies the condition, the date of discovery, the likely effect on cost and on time, and the intention to claim both is the safer course. The delay proof is also distinct. A contractor that meets rock may argue about excavation rates for months. The time question is narrower: did the condition delay work on the critical path, by how long, and what did the contractor do to mitigate? Photographs, geotechnical logs, plant records and a revised program issued at the time are the evidence. A retrospective delay analysis prepared for a dispute a year later is weaker. Variations as delay events: linking the variation claim in construction to time Too often a variation is valued, paid and closed while its time effect is never assessed. Months later, both parties argue about LDs over a period that includes the added work. A variation that adds work, changes sequence or adds a design step can delay completion. Most standard forms list variations as a qualifying cause of delay, but the time entitlement usually has to be claimed through the EOT clause. It does not happen automatically because the variation is priced. A variation claim in construction that deals only with money leaves the time open, and an open time question favours whoever controls the reserve power. The discipline is simple to state: every variation, whether directed or agreed, should record its time effect in writing, even if the answer is "nil". A contractor that prices a variation and says nothing about time invites the argument that the time consequence was absorbed. A principal that directs a variation after the date for practical completion has passed, without addressing time, invites the Probuild argument. In Probuild, variations directed late in the job were part of the factual background to the adjudicator's view that time should have been extended. How variations are valued (agreed rates, schedule rates, reasonable rates) is a contract-level question and outside this guide's scope. The time point here is separate from the price. AS 4000, AS 2124, AS 4902, GC21 and Transport for NSW forms on time The forms share a structure but differ at the edges, and the edges are where time is won and lost. For the general risk allocation under each form, see our guide to construction contracts in NSW. The time-specific differences are the ones that matter here. AS 2124 and AS 4000 are construct-only forms that give the superintendent a reserve power to extend time even without a claim. Peninsula Balmain concerned a modified AS 2124-1992 contract. The Court's reasoning concerned the reserve-power wording before it, and may be relevant to comparable reserve-power provisions in AS 4000 where the contractual wording is materially similar. Since that decision, principals commonly amend the reserve power, for example by stating that it is exercisable only for the principal's benefit, at the superintendent's absolute discretion, or with no obligation to exercise it. Read the amended clause, not the published edition. Some editions also deal expressly with concurrent delay and with delay damages for defined categories of EOT, subject to annexure entries. Check how the edition and annexure in use deal with both. Clause numbers are deliberately omitted here because amendments and editions vary. AS 4902 is the design and construct counterpart. On design and construct contracts, design development is usually the contractor's risk. The contractor's own design delays are not qualifying causes, and the latent-conditions allocation is often less favourable to the contractor. GC21, the NSW Government's general conditions, is drafted around cooperation between the parties and a principal's authorised person in place of a traditional superintendent. Its collaborative contracting framing does not remove notice requirements. It raises the stakes of conduct that looks like acquiescence (see the section on waiver and estoppel). Transport for NSW standard contracts for road and transport infrastructure typically contain detailed EOT and notice regimes, often with staged notices (an initial notice, then particulars) and their own treatment of weather and third-party interfaces. Transport for NSW uses its own suites of conditions as well as other government forms, so check the edition and amendments in the contract in use. Treat each staged notice as a separate condition until the contract tells you otherwise. Form Delivery Time position described in this guide What to check in the contract in use AS 2124 Construct only Superintendent reserve power to extend time without a claim. Peninsula Balmain concerned a modified AS 2124-1992 contract Amendments confining the reserve power to the principal's benefit, making it absolutely discretionary, or removing any obligation to exercise it AS 4000 Construct only Superintendent reserve power; Peninsula Balmain reasoning may be relevant where the wording is materially similar The same reserve-power amendments; how the edition and annexure deal with concurrent delay and delay damages AS 4902 Design and construct Design development usually the contractor's risk; the contractor's own design delays are not qualifying causes The latent-conditions allocation, often less favourable to the contractor; the reserve-power wording in the edition in use GC21 NSW Government works Cooperative framing; a principal's authorised person in place of a traditional superintendent Notice requirements still apply; conduct that looks like acquiescence carries higher stakes Transport for NSW Road and transport infrastructure Detailed EOT and notice regimes, often staged (initial notice, then particulars) The edition and Transport for NSW amendments (often GC21-based); weather and third-party interface provisions; each staged notice as a separate condition Notices, time bars and conditions precedent Who this is for: contracts administrators, and site supervisors who see the delay first. Three rules govern notices in NSW: clear time bars are enforced; conduct can undo them; and statute reaches them only at the edges. Each subsection takes one rule. Practice note: Diarise the notice window on the day of the event. The site supervisor who sees the late drawings, the rock or the stand-down should log the event that day and trigger the notice clock. The contracts administrator should diarise the contractual deadline for the initial notice and, separately, for the particulars. A notice given on day one can be refined later. A notice given after the window usually cannot be revived. Model initial delay notice (adapt to your contract's content and form requirements) To: [superintendent or head contractor's representative, as the contract requires] Contract: [contract name; notice clause] Subject: Notice of delay and intention to claim an extension of time: [event] 1. Event: On [date], [describe the event, for example: structural drawings for Level 2 had not been issued in response to RFI 047 dated …]. 2. Cause relied on: [qualifying cause and clause, for example: act or omission of the principal under clause …]. 3. Effect on the works: The event has delayed [activity], which is on the critical path in the program accepted on [date]. Our current estimate is [x] days' delay to practical completion. We will update this estimate as the effect becomes clear. 4. Cost: We expect to incur [delay costs or additional costs] and reserve our right to claim them under [clause] or otherwise. 5. Particulars: Further particulars will follow within [the period the contract requires]. We reserve all our rights, including our right to ask the superintendent to exercise its power to extend time. Time bar clauses on variation and EOT claims: how NSW courts enforce them The rule comes first because more contractor claims fail here than anywhere else: NSW enforces clearly drafted time bars. A time bar clause makes compliance with a notice requirement a condition of the entitlement. It will usually say that the contractor is "not entitled" to an extension or a variation unless notice is given within the period required by the contract, or that the principal is released from liability for a late claim. NSW courts treat these provisions as the parties' bargain. The commercial logic is that the principal needs early warning so it can investigate, mitigate, re-sequence or change design while there is still time. A clearly drafted time bar can defeat an EOT even where the principal caused the delay. That is the practical effect of Turner v Austotel. The contractor's failure to claim, not the principal's conduct, is what leaves it bound to the date. Do not expect the court to read a time bar down because the consequence is harsh or the delay was plainly the principal's. Three things still need checking before you accept that a time bar has operated: Is the requirement actually a condition precedent? Some clauses require notice but do not say what happens if it is late. That is a weaker bar. What does the notice have to contain, and has something already sent satisfied it? A request for information (RFI), a meeting minute or an email saying the works are delayed by the principal's late drawings may amount to notice if the clause does not require a particular form. Is there a reserve power that survives the bar (see the section on superintendent duties)? The time bar is a first-order issue on every delay file. Check it before any other argument is run. Waiver, estoppel and conduct that undoes a time bar On paper the time bar looks absolute. On site, conduct often softens it. A principal that consistently accepts late claims, assesses them on the merits without reserving its position, tells the contractor "don't worry about the paperwork, we'll sort time at the end", or runs the job through programs and minutes that record the principal's delay without insisting on notice may be found to have waived strict compliance. It may also be estopped from relying on the bar. Estoppel requires, in general terms, a representation or induced assumption, reliance on it by the contractor, and detriment if the principal were allowed to go back on it. The Spiers litigation in Western Australia is a reminder that estoppel arguments about time can succeed on particular facts. Estoppel is real, but it is proved day by day, not as a general atmosphere of informality. These arguments are harder than a compliant notice. The contractor carries the burden and needs documents, not recollections. The principal can protect itself with express non-waiver clauses and by reserving rights in writing whenever it considers a late claim. Contractors should treat waiver and estoppel as the fallback they are. If you have already missed the window Work through these steps in order, and do the first three this week. Check that the time bar has actually operated. Is notice a condition precedent under this clause, or only a requirement? Has an RFI, a meeting minute or an email already said what the clause requires? Ask the superintendent (or the head contractor, if it holds the power) in writing to exercise the reserve power for the identified delay, and to give reasons if it declines. Give a notice and particulars now anyway. A late notice may not satisfy the bar, but it puts the material in front of whoever holds the reserve power and answers any argument that the delay is now too difficult to assess. Collect the waiver and estoppel evidence: minutes, programs and emails that acknowledge the principal's delay, late claims assessed without a reservation of rights, and any "we'll sort time at the end" statements. Build it day by day, not as a general impression. Keep the statutory clocks in view. A time dispute does not pause the payment claim, payment schedule or adjudication deadlines. Onerous time bars and the unfair contract terms regime Two statutory and doctrinal routes are sometimes suggested for attacking a short or onerous time bar. Each has a limited role, and one is often wrongly imported from Victoria. The unfair contract terms regime. For a small trade business on a take-it-or-leave-it subcontract, this is the route worth checking first. If the subcontract is a standard form contract and the trade is a small business, an unfair time bar is void, and a party that proposes, applies or relies on it contravenes the Australian Consumer Law, being Schedule 2 to the Competition and Consumer Act 2010 (Cth) (ACL). Three practical points follow. First, the small-business test is fewer than 100 employees, or turnover of less than $10,000,000 for the last income year that ended at or before the contract was made. These thresholds, and the prohibition and penalties, apply to standard form contracts made or renewed on or after 9 November 2023, and to terms varied or added on or after that date. Older subcontracts that have not been renewed or varied are assessed under the earlier, narrower regime. Second, much of the burden sits with the party that drafted the term: a contract is presumed to be a standard form contract if a party alleges that it is, and a term is presumed not to be reasonably necessary to protect legitimate interests unless the advantaged party proves otherwise. Third, unfairness is still a contest. The term must meet the three-limb statutory test, and the head contractor will argue that early notice protects a legitimate interest. A fully negotiated head contract between sophisticated parties is unlikely to engage the regime at all. The provisions are sections 23(1), 23(2A), 23(2C), 23(4), 23(6), 24(1), 24(4) and 27(1) of the ACL. Section 26 excludes certain terms from section 23. In New South Wales, sections 27, 28 and 32 of the Fair Trading Act 1987 (NSW) apply that text as the Australian Consumer Law (NSW), and section 30(4) includes the Tribunal as a court for Part 2-3 of the ACL. Check the current thresholds and exclusions against the ACL before relying on this. Penalty doctrine. Commentators have asked whether a very short time bar that forfeits a substantial entitlement could be attacked as a penalty after Paciocco v Australia and New Zealand Banking Group Ltd [2016] HCA 28. No NSW authority has settled that question. Treat it as an open argument, not a rule. Victoria is not NSW. Section 13A of the Building and Construction Industry Security of Payment Act 2002 (Vic), inserted by section 13 of the Building Legislation Amendment (Fairer Payments on Jobsites and Other Matters) Act 2025 (Vic) (No. 43/2025), permits a notice-based time bar provision to be declared unfair. The definition includes a provision that makes entitlement to an extension of time contingent on notice. It does not apply in NSW. The NSW SOP Act contains no equivalent, and section 22(2) does not permit a NSW adjudicator to disregard a contractual time bar on Victorian principles. Superintendent duties under a construction contract: assessing EOTs Who this is for: superintendents, contracts administrators on the principal's side, and directors who appoint them. Under the NSW reserve-power cases, the superintendent's decision not to act can matter as much as any decision it makes. This section separates the three positions the cases recognise. Practice note: If you are the contractor, ask the superintendent in writing whether it is exercising or declining the reserve power for an identified delay, and why. If you are the superintendent, answer in writing with reasons. Silence helps neither party. It leaves the contractor without a decision to dispute and leaves the superintendent's reasoning open to reconstruction in hindsight. The superintendent's impartiality obligation and the dual role On commercial forms the superintendent wears two hats, and the courts expect it to know which one it has on. As agent, the superintendent acts for the principal: issuing directions, instructing variations and communicating the principal's decisions. As certifier or assessor, it decides matters between the parties: valuing payment claims, assessing EOT claims, certifying practical completion. In that second role the standard forms, and the cases, require it to act independently of the principal's commercial interest. Many forms make this express by requiring the superintendent to act honestly and fairly, within the time prescribed, and reasonably. Where the form is silent, the certifying function still carries a duty to act honestly and independently. In practice, the superintendent impartiality obligation means an EOT assessment must be based on the contract and the evidence. It must not be influenced by what the principal would prefer, even though the superintendent is often the principal's employee or consultant. A superintendent who takes instructions from the principal on EOT assessments, or declines to assess because the principal has told it to "hold the line", exposes the principal to claims that the certification was invalid. The principal may be liable if it interferes with the certifier. The unilateral power to extend time after Peninsula Balmain Sequencing matters here: first the contractor misses the notice, then the principal-caused delay is established, and only then does the reserve power become the contractor's best argument. In Peninsula Balmain Pty Ltd v Abigroup Contractors Pty Ltd [2002] NSWCA 211, the contractor had not made compliant EOT claims for delay caused by the principal. The contract gave the superintendent a unilateral power to extend time, and required the superintendent to act honestly and fairly. The Court of Appeal held that the power could be exercised for the benefit of either party, not only the principal, even though it exists largely to preserve the principal's LD regime against prevention. Because the contract required the superintendent to act honestly and fairly, and because the Court held that the reserve power had to be exercised honestly and impartially, the superintendent was obliged on the facts to extend time for the principal-caused delay despite the absence of a compliant claim. The Victorian Supreme Court followed and applied that reasoning in 620 Collins Street Pty Ltd v Abigroup Contractors Pty Ltd (No 2) [2006] VSC 491, holding that the superintendent's reserve power could be exercised for the contractor's benefit and was not confined to the principal's interests. The decision is persuasive, rather than binding, in NSW. The effect is to soften Turner v Austotel without overruling it. The contractor who failed to claim is still not "prevented". But where a superintendent holds a reserve power and is required to exercise it honestly and impartially, the contractor may still obtain an extension of time if a fair consideration of the circumstances requires one. The result remains fact-dependent. A superintendent acting honestly and fairly can take into account that a late claim has made the delay harder to assess, so the contractor should not treat the reserve power as a substitute for a timely notice. Principals responded predictably. Many NSW contracts now amend the reserve power to say it is exercisable only for the principal's benefit, at the superintendent's absolute discretion, and without any obligation to exercise it. Whether those amendments achieve their object depends on the words and on Growthbuilt (see the section on contracting out, above). Treat each amended clause as its own question. The EOT determination often surfaces in a progress certificate dispute. A superintendent's refusal to extend time feeds straight into a certificate that allows the principal to deduct LDs. The contractor's challenge to the certificate is, underneath, a challenge to the time decision. Framing it that way from the start keeps the dispute on the right issue. When the principal holds the power itself: Probuild and implied good faith The error to avoid is assuming that, without an independent certifier, there is no duty at all. The Court of Appeal held otherwise. In Probuild Constructions (Aust) Pty Ltd v DDI Group Pty Ltd [2017] NSWCA 151, DDI was a plasterboard subcontractor on a hotel redevelopment. It finished well after the date for completion, having made no EOT claims and not complied with the variation notice procedures. Probuild set off liquidated damages in response to DDI's payment claim. The subcontract had no superintendent. Probuild held the unilateral power to extend time itself, and there was apparently no express obligation to act honestly and fairly. The matter reached the Court of Appeal as a challenge to an adjudication determination. The adjudicator had decided it was unreasonable for Probuild not to have extended time, particularly where variations were directed after the date for completion had passed. McColl JA (Beazley ACJ and Macfarlan JA agreeing) held that Probuild was obliged to exercise the power to extend time in clause 41.9 honestly and fairly, "having regard to the underlying rationale of the prevention principle to which I have earlier referred or, if necessary, because there is an implied duty of good faith in exercising the discretion cl 41.9 conferred" (at [128]). That is a duty to consider and decide the question properly, not an automatic entitlement to time. The Court stressed that whether there had been acts of prevention, and whether Probuild was entitled to LDs, turned on the terms of the subcontract in the events that had happened (at [129]). Two points remain unsettled. First, the Court did not spell out the content of the implied good-faith duty. It is open whether a party holding the power must consider delay on its own knowledge, give reasons, or excuse other preconditions. Second, Growthbuilt shows that the duty can be excluded by express words. Until an appellate court fills in the content of the duty, the prudent course for a head contractor holding the power is a documented, fair assessment of the delay it caused. The prudent course for a subcontractor is not to rely on the duty at all. Proving delay: critical path, concurrency and the record Who this is for: contracts administrators preparing or testing a claim, and site supervisors who produce the evidence. Three things carry the proof: the program, the contract's rule for concurrency, and the contemporaneous record. A claim with all three is hard to reject. A claim missing one is usually rejected. Critical path, float and delay analysis methods These are the tools, mapped to their function. The contract decides which ones are compulsory. The critical path is the sequence of activities whose delay delays practical completion. An event that delays non-critical work does not, on its own, entitle the contractor to an EOT, because it does not delay completion. The claim must show that the event hit the critical path, or created a new one, and by how much. Float is the slack in non-critical activities. Who owns it depends on the contract. Some contracts say float belongs to the contractor, so a principal delay that consumes float is still compensable in time. Others say float is shared or belongs to the project, so principal delays absorbed by float give no EOT. Many say nothing. Read the program clause before assuming either way. Methods. Delay analysis methods range from simple comparisons of the as-planned program with the as-built record, through time-impact analysis (inserting the delay event into the program current at the time and measuring the effect), to windows analyses that divide the job into periods and assess critical delay in each. They differ in cost, in the records they need, and in how well they handle multiple overlapping events. The contract may prescribe a method or a program standard. If it does, use it. If it doesn't, choose a method your records can support. An elaborate analysis built on programs that were never updated during the job invites attack on its foundations. Method How it works Records it needs Best suited to Usual line of attack As-planned v as-built Compares the baseline program with what actually happened and attributes the difference to delay events Approved baseline program; reliable as-built dates Simpler jobs with few, well-separated events Assumes the baseline was achievable; struggles to separate overlapping causes Time impact analysis Inserts a modelled delay event into the program current at the time and measures the shift in completion Accepted program updates at each event date; clear event dates Prospective EOT claims made during the job Measures theoretical rather than actual effect; only as good as each update Windows analysis Divides the job into periods and identifies the critical path and critical delay in each Regular program updates and as-built records for every window Long jobs with many overlapping events, including concurrency Choice of window boundaries; a gap in updates undermines a whole window The UK Society of Construction Law's Delay and Disruption Protocol (2nd edition, February 2017) is widely referred to in Australian practice as a reference point for choosing and applying a method. It is guidance only and binds no one unless the contract adopts it. The approved baseline program and each accepted update are the documents that give any method its credibility. Without them, the analysis is an opinion. If the matter reaches a hearing, the analysis will usually be led as expert evidence, and in a construction dispute the opposing expert will test it against those documents before anything else. Concurrent delay: the contract decides it On concurrency the contract does most of the work, and the common law fills only the gaps the drafter left. Concurrent delay arises where two or more causes delay completion over the same period, and at least one is the principal's risk while another is the contractor's. The questions are whether the contractor gets time, money, both or neither. Start with the contract. Some forms and many bespoke contracts include a concurrency clause. It may deny an EOT where a contractor-caused delay overlaps. It may grant time but not money. It may direct the assessor to apportion the delay by each cause's contribution. Each approach is enforceable if clearly drafted, and each produces a different answer from the same facts. Principals commonly amend concurrency clauses in their favour, so check the special conditions. If the contract is silent, the NSW starting point is the overall-effect consideration from Turner Corp Ltd v Co-ordinated Industries Pty Ltd. A small principal delay does not wipe out the contractor's own substantial delay, and the analysis looks at the combined effect on completion rather than awarding the contractor the whole overlap automatically. How that consideration applies to evenly matched concurrent causes has not been settled by a single NSW appellate formula. Where the stakes justify it, treat a silent contract as a live argument and get delay-analysis evidence early. The records that win or lose a delay claim Everything in this part of the guide comes back to one point: the site record, not the claim document, decides the file. The records that do the work are: Site diaries, kept daily, recording who was on site, what work was done, what was stopped and why Program updates issued at the contract's required intervals, with narrative explaining changes to the critical path A delay register logging each event, its date, the cause relied on, the notice given and the claim status RFIs, with their response dates, because late answers are often the principal's delay Minutes that record, in the principal's or superintendent's own words, that a delay exists and what caused it The worst records are the ones created after the dispute starts. Programs produced months later to support a claim, diaries written up in bulk, and registers reconstructed from email searches are all open to credibility attacks that contemporaneous records avoid. Practice note: Keep one delay register that links each event to its RFI, its notice, the relevant program update and the claim. Give the site supervisor the job of opening the entry on the day of the event and the contracts administrator the job of closing it. A single register lets anyone reconstruct the file in an afternoon. Scattered emails take weeks and leave gaps. If you are a small trade without a programmer or a contracts administrator, you do not need a delay expert to protect a claim. You need a short daily record, made on the day, and a notice sent in time. A minimum diary entry covers: the date, the weather, and who was on site, including your crew and any other trades in your area what work you did, and what work you could not do why you could not do it, in one line (for example, "Level 3 ceilings not closed by others; no access") who you told, and how (text, email or site meeting) photos taken, labelled with the date and location An email to the head contractor that says, on the day, what was delayed, why, and that you intend to claim time may be enough to satisfy a notice clause that does not prescribe a form. Check your subcontract, and send the email anyway. Money for time: delay costs, disruption and acceleration Who this is for: directors and contracts administrators pricing and pursuing a contractor-side delay claim. Contractors overclaim and principals underpay here for the same reason: both treat the EOT as though it settled the money. The four subsections below separate the source of the entitlement, the proof, the global claim trap, and acceleration. Where the entitlement to delay costs comes from Three sources can pay for time, and the EOT is not one of them. A contractual delay-costs clause. Many standard forms give the contractor delay costs or delay damages for defined categories of EOT, usually principal-risk events, sometimes at a daily rate stated in the annexure and sometimes as reasonable costs incurred. The clause may exclude neutral events such as weather and industrial action. It may cap the recovery, or make a daily rate the exclusive measure. If the annexure says "nil", or the clause has been deleted, that is usually the end of the contractual route for those events. A variation. Where delay flows from a directed variation, the time-related cost may be valued as part of the variation itself. The contractor then needs to make sure the variation valuation actually includes the time-related component, not just the direct cost of the added work. Damages for breach. Where the principal's delay is a breach of contract (late access, late information, failure to cooperate), the contractor may claim damages at common law. Contractual exclusions, caps, exclusive-remedy provisions and time bars may cut this route down. Many contracts say the delay-costs clause is the only remedy for the listed events. The order of analysis follows from this. First establish the EOT, because it proves the event and its critical effect. Then find the money clause that covers that event. Then prove the amount. A contractor that skips the second step and claims "prolongation" because an EOT was granted is often told, correctly, that the EOT was for a no-cost cause. Worked example (illustrative figures only, not market benchmarks). The principal's design information arrives late and delays practical completion by 42 days. The LD rate is $5,000 a day. The contractor's time-related site costs (supervision, sheds, plant and similar preliminaries) run at $3,000 a day. The annexure provides delay costs of $2,500 a day for principal-caused EOTs. Outcome LDs deducted Time-related costs recovered Contractor's net exposure No compliant notice and no EOT $210,000 Nil $336,000 ($210,000 LDs plus $126,000 unrecovered site costs) EOT granted, but for a no-cost cause (or delay costs stated as "nil") Nil Nil $126,000 EOT granted, and the delay-costs clause applies Nil $105,000 $21,000 The gap between the first and last rows is $315,000 on a single event. The notice decides the first $210,000 of it. The money clause decides the rest. Prolongation and disruption: proving the number Prolongation and disruption are proved differently, and running one as if it were the other is a common way to lose both. Prolongation covers the time-related costs of the extended period: site supervision, site establishment, plant and equipment retained on site, insurance and bonds extended, and site-specific overheads. It is proved by showing what those resources actually cost during the extended period and that they were there because of the delay, not because the contractor was catching up on its own work. The better evidence is cost records for the specific delay period, not the average weekly preliminaries from the tender. Head-office overheads and lost profit on other work are harder claims, need evidence of actual loss, and are often excluded by the contract. Disruption covers lost productivity. It is proved by comparing the productivity actually achieved in the disrupted period against a baseline: an undisrupted period on the same job, or a reliable benchmark. It needs labour records, quantities installed and a causal story linking the disruption to specific principal acts. Disruption may not delay completion at all, so an EOT is neither necessary nor sufficient. Both claims fail when the contractor cannot separate its own inefficiencies from those caused by the principal. The records that make that separation possible are the ones described in the section on the records that win or lose a delay claim. Global claims and why they are vulnerable A total-cost comparison is not proof of causation. A global (or "total cost") claim takes the contractor's actual cost, subtracts its tender cost, and attributes the whole difference to the principal's delay events, without linking each cost to each cause. It is attractive because it is cheap to prepare when records are poor. It is vulnerable for the same reason. If any part of the overrun is attributable to something the principal is not responsible for, such as under-pricing at tender, the contractor's own inefficiency, a subcontractor's failure or a non-compensable event, the claim has not proved how much the principal caused. The whole claim can fail rather than just the unproven part. Courts have not rejected global claims outright, and a claim may survive where the contractor can show that the principal's events are the only realistic cause of the overrun and that it is not practicable to separate costs event by event. That is a heavy burden. The better practice is to allocate costs to causes wherever the records allow, and to confine any global element to the residue that genuinely cannot be separated. Two Victorian decisions are commonly cited on global claims and are persuasive in NSW: Nauru Phosphate Royalties Trust v Matthew Hall Mechanical & Electrical Engineers Pty Ltd [1994] 2 VR 386 and John Holland Construction & Engineering Pty Ltd v Kvaerner RJ Brown Pty Ltd (1996) 8 VR 681; (1997) 82 BLR 81. Directed, constructive and voluntary acceleration The three kinds of acceleration are sequenced by who decided to accelerate, and that decides who pays. Directed acceleration is an instruction from the principal or superintendent to complete earlier than the contractor is entitled to, or to recover delay the principal caused. It is ordinarily a variation, valued under the contract's variation clause. The contractor's protection is to get the direction in writing, identify it as an acceleration direction, and state that it will be claimed as a variation. Constructive acceleration is the harder claim. The contractor was entitled to an EOT, the EOT was wrongly refused or ignored, and the contractor accelerated to avoid LDs. The contractor then claims the cost of acceleration as if it had been directed. The argument has intuitive force, but whether and how it is recognised in NSW law is unsettled. It is heavily dependent on evidence: the contractor must show the EOT entitlement, the wrongful refusal, that it accelerated because of the refusal, and what the acceleration cost. It is a poor substitute for pursuing the EOT through the contract. The better course is to press the EOT through the dispute mechanism while accelerating only under express protest, with a written reservation of rights. Voluntary acceleration is the contractor's own decision to recover its own delay, or to finish early for commercial reasons. It is at the contractor's cost. Warning: Don't accelerate on a verbal instruction. A superintendent or site manager who says "get more crews on, we need this finished" has not, by saying it, issued a variation. Without a written direction, the contractor's acceleration can later look voluntary. Site supervisors should ask for the instruction in writing before mobilising extra resources and, if they don't get it, confirm it back in writing the same day. Delay down the chain: head contractors and subcontractors Who this is for: subcontractor coordinators, and directors on both sides of a subcontract. On the head contract the principal carries the principal's delay. On the subcontract the head contractor is the "principal", and it may pass on less than its drafting suggests or more than is fair. Most subcontractor disputes over time in NSW construction turn on two issues, flow-down and pass-through, and this section covers both. Back-to-back construction contracts: flowing the time regime down The recurring practical problem is a subcontract whose notice windows are longer than the head contract's, so that the head contractor learns of the delay too late to claim it upstream. A back-to-back construction contract aims to pass the head-contract time risk down to the subcontractor who causes, or suffers, the delay. For time, that means aligning three things. The qualifying causes in the subcontract should include the principal's delay events, so the subcontractor gets time when the head contractor does. The notice windows should be shorter than the head-contract windows by a workable margin, so that the head contractor can collect a subcontractor's notice and turn it into its own claim in time. The EOT decision under the subcontract should track the decision under the head contract, and the subcontract should say what happens if the head-contract assessment is delayed or disputed. Mechanical copying does not achieve this. A flow-down clause that simply incorporates the head-contract clauses into the subcontract by reference will often give the subcontractor the same window as the head contractor, which leaves the head contractor no time to pass the claim up. Conversely, a subcontract window so short that no trade can realistically comply invites the unfair-terms scrutiny discussed in the section on onerous time bars when the subcontract is on standard form terms. Practice note: Set subcontract notice windows inside the head-contract windows. Map each head-contract notice step to its subcontract equivalent, fix the subcontract step early enough to allow for collation and review, and diarise both. If you are the subcontractor, find out the head-contract window. Your practical deadline may be earlier than your subcontract suggests if you want the head contractor to carry your claim upstream. Pass-through claims, principal-supplied items and nominated trades A subcontractor's delay claim usually does not run directly against the principal. A subcontractor delayed by the principal's conduct generally claims against the head contractor under the subcontract. The head contractor then passes that delay up as its own claim against the principal. Pass-through arrangements, where the subcontract ties the subcontractor's recovery to what the head contractor recovers upstream, need careful drafting. Their enforceability depends on the words and on the SOP Act. This is where a pay-when-paid clause in a New South Wales subcontract usually runs into trouble. Section 12(1) of the SOP Act provides that a pay-when-paid provision has no effect in relation to payment for construction work carried out or undertaken to be carried out, or related goods and services supplied or undertaken to be supplied. Section 12(2)(c) also catches a provision that makes the liability to pay, or the due date, contingent or dependent on the operation of another contract. Causation governs every step. The head contractor must show that the principal's event caused the subcontractor's delay and its own delay to practical completion under the head contract. A delay that held up one trade but not the critical path of the whole project may give the subcontractor an EOT without giving the head contractor one. Items the head contractor or principal supplies, such as materials, access, design information, preceding trades and nominated subcontractors, can each be the source of prevention within the subcontract. A head contractor whose other trades delay a subcontractor's access, and which then levies subcontract LDs, is in the Probuild position (see the section on Probuild and implied good faith) unless its drafting has taken it to the Growthbuilt position (see the section on contracting out). Where several parties in the chain contributed to the same loss, proportionate liability under Part 4 of the Civil Liability Act 2002 (NSW) ("CLA") may arise, but only for an apportionable claim as defined in section 34(1), and not for a Part 2C HBA warranty claim brought by a person having the benefit of that warranty (section 34(3A) of the CLA). Where delay claims are decided: security of payment, residential work and forum Behind every delay file sit the statutory payment regime, the residential warranty regime, the contract's dispute clause and a set of running clocks. This section maps each to its function and points to the detailed guides. Delay costs and EOTs in a NSW payment claim and schedule Time disputes and statutory deadlines collide in the payment claim, and the deadlines usually win. Whether delay costs can be included in a NSW payment claim depends on the construction contract's entitlement. The SOP Act gives a right to progress payments for construction work carried out and related goods and services supplied. Under section 9, the amount is calculated under the contract. If the contract makes no express provision, it is calculated on the value of the work or related goods and services under sections 9(b) and 10. In an adjudication, section 22(2) limits the matters the adjudicator may consider. NSW has never had a statutory "excluded amounts" regime of the kind that applied in Victoria until that regime was removed from 15 April 2026. A contractual delay-costs entitlement can be claimed through the SOP Act process, and an adjudicator may deal with it only by reference to the matters listed in section 22(2). The adjudicator's approach to damages claims that are not contractual entitlements is a matter for the specialist guides. On the respondent's side, a principal that intends to deduct LDs while an EOT is under assessment faces a sequencing problem. It must decide the time question well enough to put a quantified deduction, and the reasons for withholding, in the payment schedule under sections 14(2) and 14(3) of the SOP Act. Those reasons cannot be added for the first time in an adjudication response: section 20(2B). The deduction also has to meet the due date under section 11, including sections 11(1A), 11(1B), 11(1C) and 11(8). That sequence is set out in our guidance on deducting liquidated damages while an EOT claim is pending. Two clocks matter most on a delay file. Under section 14(4) of the SOP Act, a respondent that does not provide a payment schedule within the time required by the contract, or within 10 business days after the payment claim is served, whichever expires earlier, becomes liable to pay the claimed amount on the due date for the progress payment. A separate clock applies before that stage. Under section 13(4), a payment claim may be served only within the period fixed by the contract, or 12 months after the construction work was last carried out or the related goods and services were last supplied, whichever is the later. On residential work, section 8(2) removes the progress-payment entitlement if the contract does not comply with section 4 of the HBA, or the work is residential building work done in contravention of section 92 of the HBA. For orientation, the entitlement, valuation and due-date provisions are sections 8, 9, 10 and 11 of the SOP Act, and the claim and adjudication framework is in sections 13, 14, 15, 17, 20 and 22. Currency note: the Fair Trading and Building Legislation Amendment Act 2026 (NSW) will change the label in section 14(4) of the SOP Act once the amendment is proclaimed. The in-force section 14(4) uses business days, and section 4(1) already excludes 27, 28, 29, 30 and 31 December. When this guide was last checked against the in-force text (29 September 2026), it had not changed. For the regime end to end, see our guide to security of payment and adjudication in New South Wales. For the claim and schedule mechanics, see payment claims and payment schedules in NSW. For the determination stage, see adjudication in NSW. If a delay-cost item is in a live payment claim, or an adjudication application in New South Wales is being prepared or answered, get security of payment advice from Merlo Law before the next statutory deadline, not after it. Once a schedule deadline has passed, the options narrow sharply. Warning: SOP deadlines don't wait for an EOT assessment. A superintendent's EOT assessment that is "still in progress" does not extend the payment schedule deadline, and payment schedule failure in New South Wales carries the same consequence whether or not a time dispute is running. A respondent that misses the window in s 14(4) of the SOP Act while an EOT is under assessment becomes liable under section 14(4) to pay the claimed amount on the due date. If it remains unpaid, section 15 applies. Residential building work: the Home Building Act timing warranty On commercial work the contract does most of the running. On residential work it does less than its drafting suggests. Residential building work carries the statutory warranties implied by s 18B of the HBA. The one that matters for delay is s 18B(1)(d): a warranty that the work will be done with due diligence and within the time stipulated in the contract, or, if no time is stipulated, within a reasonable time. Two features set it apart from a contractual completion date. First, it cannot be contracted out of: section 18G makes void a provision of an agreement or other instrument that purports to restrict or remove the rights of a person in respect of a statutory warranty. Second, it runs on its own limitation clock. Section 18E(1)(b) sets the warranty period at 6 years for a breach resulting in a major defect (defined in section 18E(4)) and 2 years in any other case. For a timing claim, that ordinarily means the 2-year period, because a timing-warranty claim for rent is not, without more, a major-defect claim. When that period starts depends on where the job ended up. Where the work is complete, section 18E(1)(c) of the HBA starts it on completion, determined under section 3B. For new buildings in strata schemes, completion is fixed under section 3C instead (section 3B(1A) and the note to section 3B). If the work is not complete, section 18E(1)(d) starts the period on termination, cessation of work, or the date of the contract, as applicable. Section 18E(1)(e) allows a further 6 months if the breach becomes apparent in the last 6 months, and section 18E(1A) can extend the 2-year period where a building bond has been lodged under Part 11 of the Strata Schemes Management Act 2015 (NSW). For builders, the EOT clause in a residential contract works alongside the timing warranty, not in place of it. A builder with a valid EOT for owner variations has a strong answer to a timing warranty claim for that period. A builder relying on an agreement or other instrument to shut out the warranty altogether is on weaker ground because of section 18G of the HBA. The person enforcing the warranty also has duties under section 18BA, including mitigation and written notice of the breach within 6 months after it becomes apparent. Section 18B(2) implies the warranties in a contract between a principal contractor and a subcontractor for residential building work. In practice, residential builders should run the contract's EOT process as strictly as they would on a commercial job. Owners are rarely familiar with notice clauses, so give each EOT notice in the form and to the address the contract requires, explain the cause in plain terms, and attach the variation or wet-weather record it relies on. Record the time effect on every variation document the owners sign. Where the owners claim rent or alternative accommodation for late completion, the dispute usually turns on two questions: which days of delay the builder can show were caused by owner variations, weather or other causes the contract allows for, and whether the owners' claimed costs were actually incurred and reasonably mitigated, as section 18BA of the HBA requires of them. Residential building disputes are commonly decided in the NSW Civil and Administrative Tribunal (NCAT), and NCAT jurisdiction in a building dispute has both a monetary limit and time limits. Under section 48K(1) of the HBA, the Tribunal’s jurisdiction is limited to a building claim not exceeding $500,000, or another figure prescribed by the regulations. Under section 48K(7), it has no jurisdiction over a Part 2C statutory-warranty claim lodged after the end of the section 18E period. Sections 48K(3), 48K(4) and 48K(8) impose separate 3-year limits on other building claims. “Building claim” is defined in section 48A. The forum and the regulator are covered in our guide to NCAT and the Building Commission in NSW. The NSW Civil and Administrative Tribunal publishes its own procedural guidance. If a residential delay claim is heading to the Tribunal, advice on the NCAT building dispute pathway should come before the application is filed. Currency note: sections 18B(1)(d), 18E and 18G of the HBA remain in force. Section 202 of the BAP Act does not repeal them. When a delay claim becomes a construction contract dispute in New South Wales The sequence usually runs from notice, to rejection, to the contract's dispute clause, and only then to a forum. Most delay claims start inside the contract: a notice, a claim, an assessment, a rejection. Once the superintendent's decision is disputed, the contract's dispute resolution clause governs the next step. That usually means a notice of dispute, a period of senior-level negotiation, sometimes mediation, and then expert determination, arbitration or litigation, depending on the form. Missing a step in that clause can have its own consequences, so read it as closely as the EOT clause. Where the contract does not resolve the matter, construction contract disputes in New South Wales go to forums matched to the work and the stakes. Residential building claims are commonly heard in NCAT. Commercial delay disputes of substance go to the Technology and Construction List of the Supreme Court or the District Court, and some go to arbitration where the contract requires it. The forum choices are mapped in our guide to resolving a construction dispute in New South Wales. Early dispute advice is most valuable at the notice-of-dispute stage, while mediation, expert determination or a negotiated outcome is still cheaper than a hearing. When to stop negotiating and start court proceedings is its own decision, and it should be made with the contract's dispute clause and the limitation clocks in view. A contractor that suspends work for non-payment may create its own delay, and whether that suspension is justified is a separate question. Under section 27(1) of the SOP Act, the statutory right arises only after at least 2 business days have passed since notice of intention was given under section 15, 16 or 24. A claimant who suspends in accordance with that right is not liable, under section 27(3), for loss caused by not carrying out the work during the suspension. Section 27(2A) gives a separate claim for loss or expense caused by the respondent removing work or supply during that suspension. The effect on delay and liquidated damages is covered in our analysis of suspension of work under the SOP Act and liquidated damages in NSW. Where a principal calls on a bank guarantee to recover LDs, whether a court will restrain that call is a separate question again. We outline the approach to restraining a call on a bank guarantee in our dispute resolution guide. The clocks that decide a delay file Eight clocks run on the same delay, from different triggers. Most are contractual, some are statutory, and none pauses for the others. Clock Source Trigger Period Consequence if missed Currency note EOT notice Contract Delay event, or when the contractor became aware of it Contractual notice period Possible loss of entitlement — EOT claim particulars Contract The notice Contractual period for particulars As above — Superintendent assessment Contract The claim Contractual assessment period Reserve-power and deemed-decision issues — Progress-payment due date SOP Act ss 11(1A), 11(1B), 11(1C) and 11(8) Payment claim made under Part 3 Principal to head contractor, other than an exempt residential construction contract: 15 business days after the payment claim, or an earlier contractual date (s 11(1A)). Subcontractor, other than an exempt residential construction contract: 20 business days after the payment claim, or an earlier contractual date (s 11(1B)). Exempt residential construction contract: the contractual due date, or 10 business days after the payment claim if the contract is silent (s 11(1C)). Under s 11(8), a later contractual date has no effect for a payment under s 11(1A) or s 11(1B). Section 11(8) does not apply to s 11(1C). Periods reflect the in-force business-day text. Payment schedule SOP Act s 14(4) Payment claim served Contract time or 10 business days, whichever expires earlier Liability for the claimed amount on the due date for the progress payment Reflects the in-force business-day text. Check whether the working-day amendment has commenced. Adjudication application SOP Act s 17 Payment schedule or non-payment 10 business days after receiving the payment schedule (s 17(3)(c)); 20 business days after the due date if a scheduled amount is unpaid (s 17(3)(d)); 10 business days after the end of the 5-business-day period in section 17(2)(b), where no schedule was provided (s 17(3)(e)). That route is available only if the claimant first served written notice, within 20 business days after the due date, of its intention to apply for adjudication: section 17(2)(a). Loss of adjudication for that claim Reflects the in-force business-day periods. Check whether the working-day amendment has commenced. HBA warranty proceedings HBA ss 3B, 18E(1)(b)–(e), 18E(1A) and 18E(4) Completion where the work is complete; otherwise termination, cessation or the contract date under s 18E(1)(d) 6 years for a major defect as defined in s 18E(4); 2 years otherwise; a further 6 months under s 18E(1)(e); a possible extension under s 18E(1A) Proceedings are out of time only after the applicable period Current. For new buildings in strata schemes, completion is fixed under s 3C, not s 3B (s 3B(1A)). Contract / tort limitation Limitation Act 1969 (NSW) s 14(1)(a)–(b) Accrual of the cause of action 6 years Right and title extinguished under s 63(1), subject to the section’s exceptions Applies to a contract not made by deed, and to tort. Deeds and contribution claims are dealt with separately. Section 14(1)(a) excludes a cause of action founded on a deed, and section 14(2)(a) excludes a cause of action to which section 19 applies. Section 14(2)(b) takes out a contribution claim to which section 26 applies. For contribution under section 5(1)(c) of the Law Reform (Miscellaneous Provisions) Act 1946 (NSW), section 26(1) of the Limitation Act sets the period as the first to expire of 2 years from accrual of the contribution claim and 4 years from expiry of the limitation period for the principal claim. Drafting and administering a time regime that works Who this is for: principals, superintendents, contractors and subcontractors setting up or running the time regime. The NSW cases show that most delay disputes are decided by choices made at contract formation and in the first week after an event. This section turns those choices into two checklists, one for each side of the contract. If you want construction law advice on your time regime before you sign, Merlo Law can check the proposed contract and special conditions against the points below. For principals and superintendents Four drafting decisions and three administration habits do most of the work. On drafting, start with an EOT clause that covers every principal-risk event, including a catch-all for the principal's acts, omissions and breaches. Its purpose is to prevent the argument that time is at large. Second, draft the reserve power deliberately. Decide whether it is for the principal's benefit only, whether it carries a duty to act honestly and fairly, and whether you want the Growthbuilt formulation. Then make the words say exactly that. Third, set a notice window that is workable: short enough to give early warning, not so short that it invites unfair-terms scrutiny on a standard-form subcontract or makes compliance unrealistic. Fourth, include a concurrency clause that says how overlapping causes are treated. Silence leaves it to the overall-effect analysis. If the principal is a developer or special-purpose vehicle administering the contract itself, without an independent superintendent, Probuild applies to it directly: a party holding the power to extend time is likely to be obliged to use it for delay it caused, unless the drafting clearly says otherwise. On administration, decide every claim within the contractual assessment period, with written reasons. Record the reserve power: when you consider it, whether you exercise it, and why, for each identified principal-caused delay. Keep the certifier independent: the principal should not instruct the superintendent on assessments, and the file should show that it didn't. For contractors and subcontractors The contractor's side of the regime is about systems, not advocacy. Set up a diary system for notice windows, so each event starts a clock on the day it happens. Keep a claim template that meets the contract's content requirements (event, cause, critical-path effect, days claimed, supporting program) and can be filled in within hours, not weeks. Issue program updates at the contract's intervals, with narrative that names principal delay events as they arise. Keep a single delay register as described in the section on the records that win or lose a delay claim. Refuse verbal acceleration. Ask for a written direction and, if none is given, confirm the instruction in writing the same day with a reservation of rights. For subcontractors, find out the head-contract windows and work to them, not just to the subcontract windows. Read the reserve-power clause at tender. If it contains Growthbuilt wording, your own notices are your only protection, and that should be reflected in your price and your procedures. How delay and disruption claims play out on NSW jobs Four illustrative NSW fact patterns follow. The orientation table at the start of this guide matches each reader position to one of them. They are composites for teaching, not client matters, and each closes with the lesson it teaches. Commercial warehouse on AS 4000: late design information and a missed notice The notice window closed before anyone focused on time, and that decides this one. The principal's design information for the warehouse structure arrives six weeks late. The contractor's crews stand down and then re-sequence. Everyone knows why the job is behind, but the contractor's EOT notice is not given within the contractual notice period. When practical completion slips, the superintendent declines to exercise the reserve power, and the principal starts deducting LDs. The analysis runs through the decision path in the section on contracting out. Turner v Austotel is against the contractor: it had a route to time for the principal's late information and didn't use it, so it is not "prevented". Peninsula Balmain may be for it. If the reserve power is in the unamended AS 4000 form and the superintendent is bound to act honestly and fairly, the superintendent may be obliged to extend time for the principal-caused delay despite the missed notice. The critical question is whether the principal amended the reserve power in the special conditions to make it for the principal's benefit only, discretionary, or not obligatory. If it did, the question moves to Growthbuilt. The contractor also needs delay evidence: program updates showing the design release on the critical path, and RFIs showing the dates. Waiver or estoppel is a fallback if the principal's minutes acknowledged the delay without insisting on notice. Lesson: give notice at the event, then pin down the reserve power in writing. The missed notice converts a straightforward EOT into an argument about the superintendent's duty. Fitout subcontract with an "absolute discretion" clause On facts like these, subcontractors often misread their position, assuming the head contractor must extend time for its own delay. A fitout subcontractor on a commercial job is delayed because the head contractor's other trades don't vacate the floors on time. The subcontract gives the head contractor absolute discretion to extend time and says the head contractor has no obligation to extend time or to consider doing so. The subcontractor gives no EOT notice, relying on an understanding that "everyone knows the ceilings were late". The head contractor levies subcontract LDs. On Growthbuilt-style drafting, prevention is likely excluded if no claim was made. The combination of absolute discretion and an express no-obligation clause leaves no room for the Probuild implied duty. The subcontractor's arguments narrow to waiver or estoppel on the facts. If the subcontract is a standard form issued to a small business, it may also argue that the clause is unfair under the ACL. That argument depends on the statutory criteria, the thresholds and a fact-heavy analysis of the head contractor's legitimate interests. It is not a quick answer. Lesson: the subcontractor's only reliable protection is its own notices, given within its own windows, whatever it believes about who caused the delay. Standard-form status under the ACL is worth checking, but it is a contest, not a safety net. If your subcontract contains absolute discretion wording, Merlo Law can review it before your next notice is due and set out the notice steps that protect you under it. Civil works: latent rock, wet weather and constructive acceleration When events overlap, the analysis has to be done event by event, and money has to be claimed separately from time. On a civil job under a Transport for NSW-style contract, the contractor meets rock not shown in the geotechnical information. Weeks later it loses days to wet weather above the contract allowance. It gives notices for both. The EOT for the rock is refused on the basis that the rock was foreseeable. The weather EOT is partly granted. Facing LDs, the contractor adds crews and extends shifts, and writes to the principal that it is accelerating under protest. The analysis starts with qualifying causes. Is rock a latent condition on this contract's risk allocation and site-investigation clauses? Is the weather above the allowance on the contract's measure? Next is the concurrency clause. Did any contractor-caused delay overlap either event, and how does the contract treat that? Then the money: prolongation for the extended period is only claimable if a delay-costs clause covers latent conditions (weather is commonly excluded), and disruption from the weather needs productivity evidence. The acceleration claim is the weakest part. Constructive acceleration is unsettled in NSW, and the contractor needs to show the EOT entitlement, the wrongful refusal, the causal link to the acceleration, and the cost. The written protest helps. Pursuing the rock EOT through the dispute clause remains the primary route. Lesson: run the EOT, and don't treat acceleration as a substitute. Acceleration costs are recoverable only if you win the time argument you should have been pressing all along. Residential new dwelling: owner variations and the timing warranty On residential work the statute sits behind the contract, so the builder has to win the argument on both. Under an HIA new-dwelling contract, the owners ask for a series of variations during framing and fit-off: a changed kitchen, an added ensuite window, upgraded flooring. The builder prices each variation but doesn't record a time effect on most of them. Completion runs late. The builder claims an EOT for the variations. The owners say the builder breached the timing warranty in s 18B(1)(d) of the HBA and claim rent and alternative accommodation. The builder's case depends on proving that each variation delayed completion and that the delay was claimed under the contract. Variations with an agreed written time effect are straightforward. Those without are an argument, and the owners will say the time was absorbed. Behind the contract sits the statutory timing warranty, which s 18G of the HBA protects from being contracted out. The dispute will likely be run in NCAT. If an owner refuses to sign a variation during the job, whether the builder can stop work is its own question, covered in our analysis of stopping work over an unsigned residential variation. Lesson: tie time to every variation in writing, including "nil" where that is the answer. On residential work the timing warranty is always in the background, and the builder's written time assessment is its main defence. Failure-mode library: how delay claims are lost The failures below are collected in one place because each is a process failure, not a legal one, and each is preventable. Delay claims are commonly lost in these ways: The notice was given when the claim was made, not when the event happened. By then the window had closed, and Turner v Austotel did the rest. The claim asserted delay without showing critical-path impact. Showing that work was delayed is not showing that completion was delayed. The contractor relied on prevention after choosing not to claim. In NSW, a contractor with a route to time that didn't use it is generally not "prevented". A global claim was made with no allocation of cost to cause. If any part of the overrun had another cause, the whole claim was exposed. The contractor accelerated on a verbal site instruction. Without a written direction, the acceleration looked voluntary. The subcontract's notice windows were longer than the head contract's. The head contractor learned of the delay after its own window had closed. The superintendent sat on the reserve power without recording reasons. Its silence was later reconstructed as a failure of the honest-and-fair duty. The contractor treated an EOT as an entitlement to money. The EOT was for a no-cost cause, and no delay-costs clause applied. Program updates were missing, or were produced after the event. The delay analysis then rested on reconstruction, and its credibility went with it. The SOP payment schedule deadline was missed while an EOT was "under assessment". Liability under s 14(4) of the SOP Act attached regardless of the time dispute. Conclusion The order that matters is the one this guide follows. First, identify which of the four claims you are making or answering (delay, disruption, prolongation or acceleration), because each is proved differently. Next, find the qualifying cause and confirm the notice was given at the event, within the contractual notice period. Then read the reserve-power clause and place it on the Peninsula Balmain, Probuild or Growthbuilt spectrum before arguing prevention. Prove critical delay from the programs and records made at the time, and apply the contract's concurrency rule. Only then look for the separate clause that pays for time. And run the SOP Act, HBA and limitation clocks alongside all of it, because none of them waits. That order produces the right outcome because each step removes an argument the other side would otherwise have. A notice given at the event removes Turner v Austotel. A written reserve-power request removes silence as a defence. A contemporaneous program removes the attack on credibility. A cost claim allocated to causes removes the global-claim problem. Contractors who reverse the order, arguing prevention first and gathering evidence last, tend to lose claims they should have won.

Currency notes (as at 30 September 2026) Building (Approvals and Practitioners) Act 2026 (NSW). The Act received assent on 14 August 2026. Under section 2, only Schedule 3[20] and [45] commenced on assent. The remainder, including section 202, commences on a day or days to be appointed by proclamation. Section 202 provides for the repeal of the Building and Development Certifiers Act 2018 (NSW), the Building and Development Certifiers Regulation 2020 (NSW), the Design and Building Practitioners Act 2020 (NSW), the Design and Building Practitioners Regulation 2021 (NSW) and the Environmental Planning and Assessment (Development Certification and Fire Safety) Regulation 2021 (NSW). It does not repeal the HBA, so sections 18B(1)(d), 18E and 18G remain in force. Section 12(7) of the BAP Act only permits regulations to modify how the BAP Act and the HBA apply to prefabricated buildings. Fair Trading and Building Legislation Amendment Act 2026 (NSW) (Act No 28 of 2026). The Act received assent on 14 August 2026. Schedule 1 provides for “business days” to be replaced by “working days”. When this guide was last checked against the in-force text (29 September 2026), section 14(4) of the SOP Act still used business days. Before counting a statutory deadline, check whether the enacted items have commenced. Either way, section 4(1) already excludes a Saturday, Sunday or public holiday, and 27, 28, 29, 30 or 31 December, from “business day”. The label change does not create that exclusion.

It is a contractual claim by the contractor to move the date for practical completion because a qualifying cause, such as a principal's act, a variation, a latent condition or weather above an allowance, delayed the critical path. It protects against liquidated damages for the extended period. It does not, by itself, entitle the contractor to be paid for the delay. Does the prevention principle still apply if I missed the EOT notice deadline? Generally not in NSW, if the contract gave you a route to time and you didn't use it (Turner v Austotel). Your remaining arguments are usually waiver or estoppel, or a reserve power that the superintendent or head contractor was obliged to exercise (Peninsula Balmain; Probuild). Clear "absolute discretion, no obligation" drafting can remove even that (Growthbuilt). Can a superintendent grant an extension of time if the contractor didn't claim one? Often yes, if the contract has a reserve power. In Peninsula Balmain, the Court held that a superintendent exercising such a power was required to act honestly and impartially, and that on the facts an extension should have been granted for principal-caused delay despite no compliant claim. Many principals now amend the power, so check the special conditions carefully. Can I claim delay costs as well as an extension of time in NSW? Only if there is a separate entitlement: a delay-costs clause covering that cause, a variation that includes time-related costs, or damages for the principal's breach, in each case subject to the contract's exclusions and caps. Neutral causes such as weather commonly give time without money. What does "time at large" mean in a construction contract? It means the completion date has fallen away, usually because the principal prevented completion and the contract had no working mechanism to extend time for that. The contractor must then reach practical completion within a reasonable time. LDs fall away, but general damages for delay beyond a reasonable time may still be recoverable. Who bears concurrent delay under a NSW construction contract? The contract decides first. A concurrency clause may deny time, give time without money, or apportion the delay. If the contract is silent, the NSW starting point looks at the overall effect on completion, so a small principal delay does not wipe out the contractor's own substantial delay.

KEY TAKEAWAYS A valid payment schedule under the Building Industry Fairness (Security of Payment) Act 2017 (Qld) (BIF Act) is a critical mechanism for preserving a head contractor's right to set off costs for unrectified defective work or liquidated damages. Under section 77(2) of the BIF Act, failing to serve a payment schedule by the deadline — the earlier of the contractual period or 15 business days under section 76(1) — typically exposes the respondent to liability for the full claimed amount on the due date. If an inflated claim proceeds to debt recovery as a debt owing under section 78 of the Act, a head contractor who failed to serve a valid payment schedule may be strictly prohibited from raising counterclaims, cross-claims or contractual defences that were not detailed in that schedule. Adjudicators frequently reject vague back-charges; defect deductions must be quantified and substantiated with specific evidence before the response window closes. A subcontractor's progress claim lands on your commercial manager’s desk ten days after the submission deadline, for a project that is already bleeding margin due to their poor workmanship and delays. The subcontractor is demanding full payment for the milestone, entirely ignoring the $120,000 in unrectified defective work you have been demanding they fix and the weeks of critical path delay they have caused. Under Queensland’s statutory payment regime, your contractual right to back-charge means little if you fail to formally document those deductions in a compliant payment schedule before the statutory deadline expires. This guide breaks down exactly how to draft a BIF Act payment schedule that legally substantiates your defect and liquidated damages set-offs, protecting your cash flow before the window permanently closes. The 15-Business-Day Statutory Trap vs Contractual Entitlements You have just received a heavily inflated payment claim from a subcontractor whose work is riddled with defects and running weeks behind schedule. While your immediate instinct might be to rely on your contract's dispute resolution clause to withhold funds, the clock is already ticking on your single opportunity to formally defend your margins. This section outlines how to calculate your 15-business-day response window and details the severe risks of ignoring it. Disentangling Statutory Security of Payment Obligations from Contractual Dispute Mechanisms The BIF Act operates alongside your contract and, in key respects, overrides it — for instance by rendering a pay-when-paid clause ineffective against a valid claim. Many head contractors mistakenly believe they can simply trigger a contractual mediation or arbitration clause to suspend a payment cycle while a defect dispute is resolved. However, the statutory framework operates on a "pay now, argue later" basis. You cannot rely on standard contractual mechanisms to delay or set-off against a statutory payment claim unless those deductions are expressly detailed in a valid payment schedule. If you attempt to bypass the security of payment in Queensland framework by pointing exclusively to a contractual dispute clause, you may forfeit your right to defend the claim entirely at this stage. Calculating Your Exact Response Deadline Under Section 76 A respondent must provide a payment schedule within the time specified by the contract or within 15 business days of receiving the payment claim, whichever is earlier. This deadline, set out in section 76(1) of the BIF Act, is unforgiving. Calculating this exact date often causes confusion because standard construction contracts frequently define "business days" differently than the legislation does. When a payment claim arrives, you must assess both the contractual timeframe and the statutory maximum, applying whichever date arrives first to ensure compliance. Expert insight: The trap here is rarely the 15-day count itself — it is the interaction between your contract's calendar and the Act's calendar. Most standard-form contracts (and plenty of bespoke subcontracts) define "business day" to exclude only weekends and public holidays. The BIF Act carves out more than that. Note that the same 22 December to 10 January exclusion also appears in the Queensland Building and Construction Commission Act 1991 (Qld) (QBCC Act) at sections 67U(2) and 67W(2), which cap payment timeframes for construction management trade contracts, subcontracts and commercial building contracts; confirm which definition governs your specific deadline. The BIF Act's dictionary definition of "business day" in schedule 2 excludes three discrete festive-season periods from the count: 22 to 24 December, 27 to 31 December, and 2 to 10 January (with 25 and 26 December and 1 January separately excluded as public holidays). The practical effect is an unbroken shutdown running to 10 January. Note that the QBCC Act sections 67U(2) and 67W(2) express the same carve-out slightly differently, as the single period from 22 December to 10 January inclusive; both definitions reach 10 January, but confirm which instrument governs your deadline. The upshot is that a claim served in mid-December does not accrue business days across the Christmas shutdown, and the true statutory deadline lands well into January — often much later than a commercial manager mechanically counting weekdays would assume. Where this bites hardest is the reverse scenario. If your contract specifies a shorter response period than 15 business days, that shorter contractual period governs, because section 76(1) requires you to give the payment schedule within the contractual period or 15 business days, whichever ends first. A common and costly mistake is assuming you always have the full statutory 15 days when your own subcontract has quietly bound you to a tighter window. Practically: diarise two dates the moment a claim lands — the contractual deadline and the statutory maximum — and treat the earlier one as immovable. Never let the December claim lull you into a false sense of time, and never assume the statutory 15 days rescues you from a shorter contractual clock. A misunderstanding of what constitutes a "business day" under the BIF Act dictionary is one of the most common ways head contractors inadvertently miss their response window. The Financial Consequences of Missing the Section 77 Window Failing to issue a compliant payment schedule in Queensland before the deadline expires completely shifts the balance of power to the subcontractor. Under section 77(2) of the BIF Act, if a respondent fails to provide a payment schedule within the required statutory time, they become legally liable for the full claimed sum — defects and all — on the due date for that progress payment, being the date the progress payment becomes payable under section 73 of the BIF Act (as defined in section 64). This statutory liability typically attaches even if the subcontractor's work is demonstrably defective or incomplete. Consequently, missing this critical window is likely to force the head contractor to pay an inflated claim upfront, leaving them to pursue complex and costly recovery action after the cash has already left the business. Drafting a Payment Schedule to Secure Defect and LD Set-Offs Knowing your deadline is only the first hurdle; the real battle is what goes into the document. Section 69 of the BIF Act sets the minimum content of a valid payment schedule: it must identify the payment claim, state the amount (if any) the respondent proposes to pay, and — where that amount is less than claimed — state why, including the reasons for withholding any payment. You cannot simply withhold funds by stating "the work is poor" or "you delayed the project" and expect the deduction to survive a challenge. This section details exactly how to structure your payment schedule to substantiate liquidated damages and defect back-charges so they withstand rigorous legal scrutiny. Substantiating Liquidated Damages Deductions on the Schedule To validly withhold funds for delay in Queensland, a head contractor must explicitly detail the liquidated damages deduction within the payment schedule itself. The schedule must clearly reference the specific contract clause authorising the deduction, calculate the exact period of delay attributable to the subcontractor, and state the total dollar amount being withheld based on the agreed daily or weekly rate. While liquidated damages clauses are intended to provide a pre-agreed mechanism for recovering delay costs, the enforceability of this clause depends on strict compliance with the contract's notice and assessment procedures. Where the deduction is taken from a security or retention amount under a building contract, section 67J of the QBCC Act additionally requires the contracting party to give written notice of the proposed use and the amount owed within 28 days of becoming aware, or when it ought reasonably to have become aware, of the right to that amount. Furthermore, if a subcontractor challenges the set-off, courts and adjudicators may determine the deduction is unenforceable if the rate is found to operate as a penalty rather than a genuine pre-estimate of loss — the penalty versus liquidated damages distinction that decides whether a delay-damages clause is enforceable at all. Detailing Back-Charges for Unrectified Defective Work To successfully withhold payment for defects in Queensland, a payment schedule must quantify the exact rectification costs and identify the specific contractual breach. The estimated cost of rectifying a defect is expressly recognised in the valuation of construction work and related goods under section 72(1)(b)(iv) and section 72(2)(b)(iv) of the BIF Act. These provisions operate where the contract does not itself provide for how the work is valued, and they supply the statutory basis for having substantiated rectification costs taken into account in the valuation. If a disputed claim is already on the clock, Merlo Law can pressure-test your defect and delay deductions against the schedule's evidentiary requirements before your response window closes — while the deadline can still be met. When drafting the schedule to substantiate a back-charge for subcontractor defects, ensure the document explicitly includes: The specific defective item or area of non-compliant work, referencing the breached contractual specification, drawing, or standard. Photographic evidence, site reports, or superintendent directions confirming the existence and extent of the defect. Detailed, itemised third-party quotes or a breakdown of the exact internal labour and material costs required to rectify the work. Clear calculations linking the total withheld amount directly to the substantiated rectification costs, rather than relying on arbitrary estimates. Why Vague Set-Off Claims Fail at Adjudication Providing generic or "global" assertions about poor workmanship in a payment schedule is a critical tactical error if the dispute progresses to adjudication in Queensland. When an adjudicator is appointed under section 81 of the BIF Act, that decision-maker is confined by section 88(2) to considering only the Act, the contract, the payment claim and the payment schedule (with their properly made submissions), and any inspection — and typically requires concrete evidence linking the withheld amount to a specific contractual breach. Broad statements like "withholding $50,000 for defects" are highly likely to be rejected for lacking sufficient detail, which can result in the adjudicator awarding the full claimed amount to the subcontractor. Expert insight: Adjudicators are not looking for polish — they are looking for a paper trail they can follow from the withheld dollar figure back to a specific contractual breach. The question in their mind is simple: "Can I identify what was defective, why it breaches the contract, and how the respondent arrived at this exact number?" If any link in that chain is missing, the deduction tends to fall over. The classic failure is the "global" back-charge: a lump sum for "defective works" or "delay costs" with no itemisation behind it. A schedule that withholds $120,000 without a line-by-line breakdown invites the adjudicator to treat the entire figure as unsubstantiated — and while the adjudicator must still value the work under section 72 of the BIF Act, the practical result is often that little or none of the back-charge survives and the claimant recovers most of the sum withheld. For liquidated damages, the scrutiny shifts to mechanism. Adjudicators typically check that you have identified the delay period with actual dates, applied the contractual rate correctly, and — critically — complied with any condition precedent to claiming LDs, such as an extension-of-time determination or a superintendent's certificate. Skip the notice machinery and the set-off is exposed, regardless of how genuine the delay was. The tactical lesson practitioners learn quickly is that the schedule is not the place to be economical. Over-particularise. Attach the quotes, cite the specification clause, show the arithmetic. A schedule that reads like a mini-submission is far harder to dislodge than one that reads like a summary — and remember, you cannot cure these gaps later, because section 82(4) of the BIF Act locks your adjudication response to the reasons in the schedule. Navigating Debt Recovery Threats When a Subcontractor Escalates Even with a robust payment schedule issued, an aggressive subcontractor may reject your set-offs and escalate the matter, whether by adjudication, debt recovery, or a notice of intention to suspend work under section 78(3) and section 98 of the BIF Act. Whether they file for statutory adjudication or attempt to recover the disputed amount as a debt in court, the BIF Act heavily restricts how you can defend yourself. This section explains the critical limitations on your legal defences once formal recovery action commences. Why the BIF Act Strips Your Right to Raise Unscheduled Counterclaims in Court The Act strips this right because the legislation is designed to mandate cash flow by strictly preventing respondents from ambushing claimants with delayed contractual disputes during the debt recovery phase. Under section 100(3) of the BIF Act, a Queensland respondent who fails to provide a payment schedule is generally barred from raising cross-claims or contractual defences in a summary judgment application to recover the claimed amount as a debt. While section 78 gives the claimant the right to pursue the unpaid amount as a debt in court, it is section 100 that governs those proceedings: section 100(2) prevents judgment being given unless the court is satisfied no payment schedule was given in time, and section 100(3) expressly strips the respondent of any counterclaim or contractual defence. Warning: If a claimant seeks to recover the unpaid portion of the amount claimed from the respondent, as a debt owing to the claimant, in a court of competent jurisdiction under section 78(2)(a) of the BIF Act, a head contractor who failed to serve a schedule is typically prohibited under section 100(3) from deploying defects or liquidated damages as a defence. Unmitigated exposure to these enforceable statutory debts can rapidly drain working capital and may escalate into serious insolvent trading risks for the company. Preparing Your Evidence for Statutory Adjudication Under Section 79 Alternatively, the claimant may escalate by lodging an adjudication application in Queensland under the statutory pathway. When the claimant is entitled to apply for adjudication because of a failure by the respondent to pay an amount owed under section 79 of the BIF Act, the head contractor faces extremely tight deadlines under section 83 to submit their response, with the applicable period depending on whether the claim is a "standard" or "complex" payment claim (the $750,000 threshold defined in section 64). According to QBCC published data, 278 adjudication applications were received in the 2020–21 financial year, illustrating that this rapid dispute mechanism is heavily utilised by subcontractors in Queensland; more recent annual reports show the volume continues to fluctuate year on year. It is a strict procedural rule under section 82(4) of the BIF Act that a head contractor's adjudication response must not include any "new reasons" for withholding payment that were not detailed in their payment schedule; section 82(2) further prevents a respondent who failed to give a schedule from lodging any adjudication response at all. To prevent an adverse decision, practitioners know that a successful adjudication response requires a rapid compilation of evidence bundles that directly map to the scheduled reasons; you cannot introduce new contractual arguments or entirely new defect reports at this stage. Respondents routinely engage a Queensland construction lawyer to navigate these fast-tracked proceedings. Merlo Law can review your evidence bundle against your scheduled reasons and prepare your adjudication response before the statutory deadline closes — the point at which your position is locked. Conclusion When that subcontractor’s inflated claim arrives for work that is defective and delayed, your initial frustration must immediately translate into procedural discipline. You now know that relying on contractual dispute mechanisms will not suspend your statutory obligations under the BIF Act. Failing to formalise your deductions within the 15-business-day window exposes you to severe financial liability, stripping away your right to raise those legitimate defect and delay set-offs if the dispute progresses to court. Protecting your project margins requires more than just knowing the work is poor; it requires proving it on paper before the clock runs out. If you are currently holding a disputed payment claim, immediately quantify your rectification costs and draft a payment schedule that explicitly links those figures to the breached contractual specifications. FAQs What happens if a head contractor misses the 15-business-day response window in Queensland? If a head contractor misses the statutory deadline to serve a payment schedule, they typically become liable for the full claimed amount on the due date. This liability attaches regardless of the actual quality of the subcontractor's work. Failing to respond leaves the head contractor highly exposed to summary judgment or statutory adjudication. Can I rely on my contract's dispute resolution clause to delay a progress payment? No, you cannot rely solely on your contract's dispute resolution clause to withhold or delay a progress payment. The BIF Act operates on a strict "pay now, argue later" basis that overrides standard contractual mediation or arbitration delays. Any intended deductions must be formalised in a compliant payment schedule. How do I legally include liquidated damages in a BIF Act payment schedule? To include liquidated damages, the payment schedule must explicitly reference the specific contract clause, state the exact period of delay, and calculate the total financial deduction. However, the enforceability of this set-off often depends on whether you have strictly complied with the contract's formal notice and assessment procedures. Why do adjudicators frequently reject vague defect back-charges? Adjudicators typically reject vague back-charges because a valid payment schedule must sufficiently detail the reasons for withholding funds. Stating "global" defect claims without identifying the breached specification, providing photographic evidence, or itemising the exact rectification costs often fails to meet the required evidentiary standard. Does the BIF Act prevent me from raising counterclaims in court? Yes, under section 100(3) of the BIF Act, a Queensland respondent who fails to provide a payment schedule is generally prohibited from raising cross-claims or contractual defences when the claimant recovers the amount as a debt in court under section 78. This strict rule is designed to prevent respondents from ambushing claimants during debt recovery proceedings. Can I add new reasons for withholding payment during an adjudication? No, a head contractor cannot introduce new reasons for withholding payment once the matter reaches adjudication. By law, your adjudication response is strictly limited to the specific arguments and deductions you already detailed in your original payment schedule.

KEY TAKEAWAYS Receiving a QBCC direction under section 72 of the Queensland Building and Construction Commission Act 1991 (Qld) does not automatically establish civil liability for a failed pipeline pressure test, but failing to comply is likely to constitute a statutory offence. If third-party site machinery damaged the underground pipeline after installation, the contractor's strongest regulatory argument is generally that it would be unfair to give the direction under section 72(5) of the Queensland Building and Construction Commission Act 1991 (Qld), and that the contractor did not carry out the defective work within the meaning of section 71I — not the narrow section 74 defence, which is confined to cases where a contractor's licence details were used on a contract without authority. Merely lodging an internal review does not pause the compliance clock; pipeline contractors typically require a QCAT stay to legally suspend the enforcement of the direction. Rectifying under protest can help mitigate the risk of licence suspension, but the protest must be carefully documented to preserve potential variation claims for the repair work. You are staring at a failed hydrostatic pressure test on a newly laid sewer main, knowing your crew bedded, laid, and tested the pipe perfectly before site handover. But another trade just drove a 20-tonne excavator over the shallow trench, crushing the alignment. Now, the Queensland Building and Construction Commission (QBCC), acting under the Queensland Building and Construction Commission Act 1991 (Qld) (the Act), has sent a formal direction to rectify, dropping the problem squarely onto your lap with a ticking compliance deadline. If you ignore the notice, you risk a statutory offence, demerit points, and potential licence suspension right when your business has active pipeline contracts running across the state. But if you immediately dig up the trench and fix the pipe without a strategy, the head contractor is likely to use your compliance as proof that the defect was your fault all along, leaving you to foot the bill for someone else's damage. This article breaks down exactly how to handle the regulator's demands while legally quarantining your right to pursue commercial recovery for the repair work. The Immediate Crisis: Pause the Compliance Clock or Mobilise the Crew? With a QBCC direction sitting on your desk and the deadline approaching, your primary focus must shift from arguing over who caused the damage to managing the regulator's timeline. This section breaks down the immediate procedural levers you must pull to pause the statutory clock before you face regulatory penalties or licence suspension. Do Pipeline Operations Qualify as Regulated "Building Work" — and Do You Even Need a Licence? This question cuts two ways, depending on who you are. Licensed plumbers and drainers already know they sit squarely under the regulator, but many civil contractors wrongly assume their underground infrastructure projects fall entirely outside the jurisdiction of the Queensland Building and Construction Commission. Both assumptions can be costly. If a large pipeline or main is in fact "building work" under the Act, a civil contractor who carried it out without the appropriate licence is not just exposed to a direction to rectify — they may have been contracting unlawfully in the first place. So before you argue about who caused the failure, you need to know whether the work was regulated "building work" at all, and whether you were licensed to do it. Regulated plumbing and drainage work falls within the statutory definition of building work under Queensland law, and much civil pipeline and main work can too — which both gives the QBCC jurisdiction to issue a direction to rectify and, for an unlicensed civil contractor, may expose them to a separate unlicensed-contracting offence. This means that if a pressure test fails on work that is "building work," the regulator has authority to step in, and the same statutory mechanics apply whether the job is a major civil pipeline or a smaller plumbing and drainage installation. A licensed plumbing or drainage contractor facing a direction to rectify a defective plumbing work claim is governed by the identical section 71H to section 74 rectification framework of the QBCC Act. For plumbers and drainers, this is familiar territory: they are licensed, they are already the subject of QBCC regulation, and the rectification framework in this article applies to them directly. The critical question for them is strategic — how to respond to the direction — not whether they are captured by it. For civil contractors, there is a prior and more dangerous question. Many operators laying large pipelines or mains have never turned their mind to whether that work is "building work" requiring a QBCC licence at all. The position is not automatic in either direction. Item 11 of Schedule 1 to the Queensland Building and Construction Commission Regulation 2018 (Qld) excludes work for water reticulation systems, sewerage systems and stormwater drains from "building work" — but only where the work does not connect a particular building to a main of the system. Where a pipeline or main does connect, or is undertaken to connect, a particular building or proposed building to the main, the exclusion falls away and the work can be regulated "building work." The Queensland Supreme Court has grappled with exactly this line, holding sewer and water reticulation works on unregistered lots to be outside "building work" in one matter while treating other civil installations as caught in others. The stakes of getting this wrong are not confined to a direction to rectify. Carrying out "building work" without the appropriate licence is an offence under section 42 of the Act, and an unlicensed contractor can be left unable to recover any consideration for the work — meaning a contract can effectively be rendered void with no entitlement to payment. So a civil contractor who receives a QBCC direction over a failed pipeline may face a double exposure: the rectification demand under section 72, and the discovery that they were performing unlicensed building work all along. Where that risk is live, the first priority is often to confirm the licensing position before responding to the direction, because the two problems interact. For Queensland building and construction lawyers dealing with these disputes, the first step is therefore often to clarify two things at once: whether the specific pipeline or main is regulated "building work," and whether the contractor held the licence required to perform it because the answers dictate both the exposure and the response. Why an Internal Review Does Not Stop the Section 73 Statutory Offence Clock Expert insight: The trap that catches contractors again and again is treating the QBCC internal review as if it buys them time. It does not. A QBCC direction to rectify specifies a compliance period on the face of the notice. Under section 72(4) of the QBCC Act, that period must be the period prescribed by regulation — in most cases 35 days under the Queensland Building and Construction Commission Regulation 2018 — unless the commission is satisfied a shorter period is warranted on safety or substantial-loss grounds. That period runs from the date of the direction rather than from the date you lodge any challenge. The compliance date on the direction keeps running while the review sits in the queue, and section 73 makes non-compliance by that date an offence in its own right — the review being "on foot" is no answer to it. Non-compliance under section 73 carries a maximum penalty of 250 penalty units (currently up to $43,175 for an individual and $215,875 for a company on prosecution), and the regulator may also apply demerit points to your licence. Separately, section 72C makes it an offence, also carrying a maximum penalty of 250 penalty units, to delay rectifying the work or to obstruct another person carrying out the rectification required by the direction. Where this bites hardest is timing. Internal review outcomes are not instant, and a contractor who waits for the result before acting can find the compliance date has already passed by the time the review is decided. By then the offence has crystallised and the demerit exposure is live, regardless of how the review ultimately lands. This matters commercially because demerit points accumulate against your licence under Part 3E of the QBCC Act. Once the commission considers that an individual has accumulated 30 demerit points in a three-year period (section 67AZD), it may cancel the licence and treat the person as not fit and proper for a term of three years for a first occasion, or for life on a second or subsequent occasion (sections 67AZF and 67AZM) — the practical end of your ability to hold pipeline contracts across the state. The practical fix is to run two tracks at once: lodge the internal review to challenge the merits, and file the Queensland Civil and Administrative Tribunal (QCAT) application together with a stay request under section 22 of the Queensland Civil and Administrative Tribunal Act 2009 (Qld) (the QCAT Act) to freeze the clock. Treat them as separate tools doing separate jobs — one attacks the direction, the other protects your position while that fight plays out. On the stay itself, the tribunal is weighing the balance of convenience and whether you have an arguable case, so give it something concrete to hold onto. In a third-party damage scenario that means front-loading the evidence that the defect may not be yours — the passed pre-handover test certificate, the handover record, and any early indication of intervening machinery damage — rather than a bare assertion that the direction is wrong. A stay is discretionary and never guaranteed, so the stronger the causation material you can put up early, the better your prospects of holding the line while the true cause is investigated. Applying for an Extension Under Section 72B to Investigate Intervening Damage If a QCAT stay is not immediately viable, another procedural mechanism is to request more time directly from the regulator. Section 72B of the Act states that a person given a direction to rectify or remedy may apply to the commission for an extension of the period for compliance. When applying for this extension to investigate intervening damage, your submission should typically include: Formal written request before expiry: The application must be submitted prior to the original compliance deadline expiring. Evidence of third-party investigation: Provide proof that you are actively seeking third-party evidence, such as pending CCTV pipeline inspection reports. Scheduling joint independent inspections: Show correspondence proving you have requested the head contractor and an independent engineer attend the site to inspect the crushed pipe. Timeline for resolution: Offer a clear, revised timeline detailing exactly when the investigation will conclude and when any necessary repair works could realistically commence. Separating Regulatory Directives from Commercial Liability for the Pipeline Failure At this stage, the head contractor is likely using the regulator's intervention as proof that you are entirely liable for the defective work under the subcontract, threatening back-charges and withholding payments. This section untangles your statutory obligation to satisfy the regulator from your commercial right to dispute financial liability for the pipe failure. Untangling Section 72 of the QBCC Act Regulatory Powers from Subcontract Defect Liability A critical point of confusion arises when contractors conflate the regulator's statutory power with their own commercial liability. Section 72 of the Act provides that the commission may direct the person who carried out the building work to rectify the building work. This is a powerful regulatory tool designed to ensure non-compliant work is fixed promptly to protect public health and safety. A QBCC direction to rectify under section 72 of the Act is a regulatory enforcement tool, which operates separately from a contractor’s civil liability for defects under a commercial subcontract. Complying with a direction to rectify defective work satisfies the regulator under the Queensland Building and Construction Commission Act 1991 (Qld) and the Queensland Building and Construction Commission Regulation 2018 (Qld), but it does not dictate who ultimately pays for that work. You can satisfy the regulatory demand to repair the pipeline while separately pursuing the head contractor for the costs if their site management caused the failure. The commercial claim runs on its own clock, and it is important not to confuse the two limitation regimes at play. On the regulatory side, section 72A(4) provides that the commission cannot give a direction to rectify more than six years and six months after the building work was completed or left in an incomplete state, unless QCAT extends that time. Separately, on the civil side, a latent defect pipeline claim can surface long after handover because underground failures are often hidden until a later inspection or failure, so the limitation period for defective work under the Limitation of Actions Act 1974 (Qld) is a live risk you must diarise the moment a dispute emerges. Satisfying the regulator quickly does not stop that commercial limitation period from running, and a recovery claim left too long can become time-barred even where the causation evidence is strong. Preserving Evidence: Demanding a Joint Independent Hydrostatic Re-Test Warning: Destroying the accident scene by prematurely excavating the failed pipeline without independent oversight is likely to severely compromise your ability to prove third-party damage. If you immediately dig up the crushed pipe, the head contractor can often argue that the failure was caused by your poor bedding or jointing techniques, and without the undisturbed site as evidence, defending against that allegation becomes exceedingly difficult. Before any rectification work begins, contractors should formally demand a joint independent hydrostatic re-test and CCTV inspection, ensuring all parties are present to document the exact location and nature of the damage. Engaging a Queensland Building and Construction Commission lawyer before you excavate can ensure the joint re-test is properly demanded, the inspection is attended by the right parties, and the evidence is captured in a form that will hold up if the head contractor later disputes causation. Resisting the Direction to Rectify Under Section 72 of the QBCC Act: When Site Machinery Causes the Pressure Drop You know your crew bedded, laid, and tested the pipe perfectly before site handover, only for another trade to run a 20-tonne excavator over the shallow trench. This section breaks down the specific legal defence available when you can prove another party is responsible for the defective state of the work, shifting the focus from your installation to their site management. The "Unfairness" Discretion Under Section 72 of the QBCC Act and the Limited Section 74 Defence If the regulator issues a direction, you are not entirely without options if the defect wasn't your fault. The common misconception is that section 74 provides a general defence of not being responsible for the defect. It does not. Section 74 is a narrow defence available only to a licensed contractor whose name, licence number or address was included on the contract or insurance notification form without the contractor's authority, and it does not assist a contractor who installed the work and later says a third party damaged it. The correct regulatory levers for a third-party damage scenario sit in section 72. Under section 72(3), the commission may take into account all the circumstances it considers reasonably relevant and is not limited to the terms of the contract; and under section 72(5), the commission is not required to give the direction if it is satisfied it would be unfair to give it. Section 71I, which defines who is taken to have "carried out" the building work, is also central, because a contractor who can show the failure resulted from intervening third-party conduct after handover may argue the defective state should not be sheeted home to them. This typically involves persuading the commission, before it decides whether to give the direction, that an intervening event broke the chain of causation after your work was completed — in plain terms, that something happened after you finished which caused the failure and severed the link back to your installation. If you can demonstrate that third-party machinery caused the failure, proportionate liability for Queensland contractors under the Civil Liability Act 2003 (Qld) becomes central to the subsequent commercial dispute over who bears the cost of the damage. Where several parties contributed to the loss — for example the contractor, the head contractor and the design engineer — they may be treated as concurrent wrongdoers, with liability apportioned between them, and a contributory negligence argument may further reduce your share where another party's conduct helped cause the defect. Proving Intervening Damage: CCTV, Trench Compaction Logs, and Site Diaries Example: Consider a scenario where a pipeline contractor finishes installing a sewer main, passes the initial pressure test, and formally hands the trench back to the head contractor. Two days later, heavy machinery traverses the alignment, crushing the pipe. To resist the direction under section 72(5) and rebut responsibility under section 71I, the contractor presents the initial successful pressure test certificate, time-stamped daily site diaries detailing the handover, and compaction logs proving the bedding met the required specifications. Furthermore, they cross-reference the Code of Practice for Excavation Work and safety protocols mandated by Workplace Health and Safety Queensland to show the head contractor failed to restrict heavy plant access over the newly backfilled trench. They then produce post-incident CCTV footage showing the pipe is crushed from above, not separated at the joints, strongly supporting the argument that intervening surface weight, rather than poor workmanship, caused the defect. In a contested matter, this documentary record is typically supported by expert evidence on the pipeline defect — an independent engineer's opinion interpreting the CCTV and failure mode — which carries far more weight than the contractor's own assertion about how the pipe failed. The Subcontractor's Dilemma: Flawed Engineering Designs vs. Execution Failures Expert insight: Not every failed pressure test comes down to physical damage. Sometimes the pipe was built exactly to the drawing, and the drawing was the problem. An argument that the failure traces to a defective design rather than defective installation can reach these cases, but the evidentiary bar is higher than contractors expect, because "I only did what I was told" is easy to assert and hard to prove after the fact. The distinction that matters is between installing to a defective design and installing defectively. If the workmanship is sound and the failure traces back to the design — inadequate grades, wrong bedding specification, undersized pipe — then the argument that the failure was not caused by your workmanship has real teeth. If the install itself was sloppy, no amount of design blame will save it. What tends to carry weight is a contemporaneous paper trail, not a reconstruction built once the dispute is running. A request for information querying the design, a written response or site instruction directing the subcontractor to build it as drawn, and a dated record of the concern being raised before the pipe went in are far more persuasive than a statement prepared for the hearing. The common failure is the verbal warning. Contractors routinely raise design doubts on site, in the shed, or over the phone, and none of it survives if it was never put in writing. If you flagged a design concern and the head contractor waved you on, get that exchange into an email or an RFI the same day — that document is often the difference between wearing the direction and shifting it back up the chain. Bear in mind that even a strong position resisting the direction on the regulatory front does not automatically resolve who pays commercially. The design responsibility question, and where it sits under the subcontract, is a separate fight that runs alongside the QCAT process rather than being decided by it. Executing "Rectification Under Protest" to Secure Future Variation Claims If QCAT refuses a stay, or if commercial realities dictate that you must fix the pipe immediately to keep the project moving, you face a critical choice. This section explains how to mobilise your crew to perform the repairs while legally quarantining your right to claim the costs back from the party who actually caused the damage. The Legal Mechanics of Responding "Under Protest" Without Admitting Fault When faced with an immovable regulatory deadline and a head contractor who refuses to concede fault, contractors often feel trapped between risking their licence and paying for someone else's mistake. In these scenarios, proceeding "under protest" is a critical strategic tool, but it requires highly precise communication to ensure the head contractor cannot argue that your willingness to repair the pipe is an admission of defective workmanship. Rectifying defective pipeline work "under protest" in Queensland involves complying with a statutory direction to avoid regulatory penalties, while formally reserving all contractual rights to pursue compensation for the repair work. Executing this strategy successfully allows you to comply under protest or seek a QCAT stay while keeping your commercial claim alive. The written communication must explicitly separate your regulatory compliance from your contractual obligations. Drafting the Notice: Reserving Rights for Quantum Meruit and Variation Recovery Before mobilising your crew to dig up the crushed sewer main, you must issue a formal "Notice of Rectification Under Protest" to the head contractor. A variation clause is designed to provide a structured mechanism for a contractor to claim additional payment for changes in the scope of work. However, the enforceability of this clause depends heavily on the contractor issuing the correct notices at the correct time. Because these clauses are conditional, their effectiveness turns on strict compliance with time-bar notice periods. Your notice should typically include: Explicit purpose of work: A clear statement that the excavation and repair works are being performed strictly to mitigate regulatory risk under the QBCC direction, and not as an admission of civil liability for the defect. Invocation of the variation clause: A formal notification under the subcontract's variation provisions, treating the repair work as a directed change in scope. Framing the repair as outside your original scope of works turns a potential scope of works dispute to your advantage and guards against the head contractor later characterising the work as an unapproved variation you must absorb. Reservation of equitable rights: A documented reservation of your right to pursue a variation claim or seek reasonable remuneration for construction work under quantum meruit principles once the repair is complete. Notice of delay: A formal warning that the repair works may impact the critical path of the project, establishing grounds for a potential extension of time claim. Navigating Back-Charges When the Head Contractor Rectifies the Pipeline Warning: Outright refusing to rectify the pipeline without first securing a QCAT stay can expose your business to severe financial retaliation. If you abandon the defective work, the head contractor is likely to step in, engage a third party to perform the repairs, and deduct those costs from your next progress payment. These deductions often manifest as an inflated rectification cost dispute, forcing you onto the defensive in a complex security of payment battle. Where the head contractor withholds or back-charges against a certified amount, your fastest route to recovering cash flow is often a payment claim and adjudication application under Chapter 3 of the Building Industry Fairness (Security of Payment) Act 2017 (Qld), which runs on strict statutory timeframes of its own. If you find yourself facing imminent back-charges while trying to navigate a regulatory direction, you should obtain advice from a construction lawyer to assess your options for preserving cash flow. Conclusion That crushed sewer main and the ticking compliance deadline on the regulator's letterhead do not have to dictate a complete commercial loss for your business. By understanding the distinct boundary between a statutory direction and your subcontract liability, you can strategically navigate the crisis without unnecessarily forfeiting your right to payment. You now know that an internal review will not pause the statutory offence clock on its own, and that resisting a direction on the basis of third-party damage — through the unfairness discretion in section 72(5) — requires meticulous evidence preservation. More importantly, you understand how to execute repair works under protest to satisfy the regulator while keeping your variation claims alive. The two things that decide these matters — the compliance clock and the undisturbed evidence in the trench — are both lost by waiting. Before the compliance date passes or a single piece of machinery breaks ground, the notice of rectification under protest and the demand for a joint independent inspection need to be drafted and served. Merlo Law acts for Queensland pipeline and civil contractors in exactly these situations: contact us to have your protest notice, stay strategy and evidence-preservation demands prepared while there is still time to protect both your licence and your right to recover the cost. FAQs Does a QBCC direction to rectify mean I am legally at fault for the pipeline defect? No, a direction under section 72 does not automatically establish civil liability under your subcontract. It is a regulatory enforcement tool used to ensure non-compliant work is addressed, which operates separately from determining who bears the ultimate financial responsibility for the damage. Can I just lodge an internal review with the QBCC to stop the compliance deadline? No, lodging an internal review does not pause the statutory clock under section 73 of the Act. To legally suspend the enforcement of the direction and mitigate the risk of a statutory offence, contractors typically need to file a concurrent application to QCAT for a formal stay. How do I resist a direction to rectify when a third party caused the failure? Section 74 is a narrow defence confined to cases where a contractor's licence details were used on a contract without authority, so it will not usually assist a third-party damage scenario. The correct approach is to persuade the commission, before it decides whether to give the direction, that it would be unfair to give it under section 72(5), supported by evidence that an intervening event, such as a head contractor's heavy machinery driving over a backfilled trench, caused the pipeline to fail after installation. How do I rectify pipeline work under protest in Queensland? Rectifying under protest involves complying with a statutory direction to avoid regulatory penalties, while formally reserving all contractual rights to pursue compensation. This typically requires issuing a precise written notice to the head contractor before commencing repair work, explicitly stating that the repairs are not an admission of liability. Will a variation clause protect me if I fix the damaged pipe? A variation clause is designed to provide a mechanism to claim additional payment for scope changes, but it does not offer absolute protection. The enforceability of this clause depends heavily on strict compliance with notice periods, meaning failure to submit your claim on time can result in forfeiture of the payment. What happens if I ignore the QBCC direction without a QCAT stay? Failing to comply with a direction to rectify without a valid extension or a QCAT stay is likely to constitute a statutory offence. The consequences can include severe regulatory penalties, accumulation of demerit points, and potential suspension or cancellation of your contractor licence.

KEY TAKEAWAYS The 2024 amendments to the Environmental Protection Act 1994 (Qld) introduce a direct criminal offence under section 319(2) for breaching the general environmental duty where the breach causes, or is likely to cause, serious or material environmental harm. That changes the risk profile for environmental consultants. The notification duties applied by section 320A of the Environmental Protection Act 1994 (Qld) are now triggered where a person carrying out an activity "ought reasonably to have become aware" of an event causing or threatening serious or material environmental harm. Where the duty applies to a consultant, it overrides contractual confidentiality clauses, including during preliminary site investigations. Consolidated Environmental Enforcement Orders (EEOs) are likely to accelerate pass-through professional negligence claims as clients attempt to shift compliance costs back onto their advisers. Environmental consultants drafting Transitional Environmental Programs (TEPs) should deliberately demarcate their compliance advice from the client’s operational execution to mitigate direct regulatory targeting. You check your phone on a Tuesday morning to find a frantic message from a facility manager: a primary storage bund has failed, releasing contaminants into a nearby waterway and directly breaching the Transitional Environmental Program (TEP) your firm finalised last month. The client is facing significant clean-up costs, but your immediate problem is the methodology section of the TEP that bears your signature. Since the Environmental Protection (Powers and Penalties) and Other Legislation Amendment Act 2024 (Qld) amended the Environmental Protection Act 1994 (Qld) (EP Act), a client's physical site failure can quickly trigger a regulatory investigation into whether the consultant's underlying advice fell short of the general environmental duty (GED). Breach of that duty is now an offence in its own right. This article explains how the amended duties apply to environmental consultants, and the drafting and documentation steps that help separate your advice from a client's operational failures. Mapping the Immediate DETSI Exposure: TEP Drafting vs. Client Operational Failures You've just been told about the containment failure, and the client already wants answers. Your first question is whether the regulator will look only at the client’s operational failures, or also at your firm’s advice, and specifically whether the transitional environmental program your firm designed contributed to the breach. A TEP is typically the operator's route back into compliance, often with its environmental authority conditions, so the regulator will want to know whether the program failed or the client failed to follow it. This section sets out the regulatory and civil pathways you face in the first days after a TEP breach, and how to keep your exposure separate from the client's. The New Section 319(2) General Environmental Duty Offence vs Professional Negligence Claims When a TEP fails, consultants face two distinct legal pathways: statutory regulatory enforcement and civil liability claims from the client. Historically, the general environmental duty under the Environmental Protection Act 1994 (Qld) functioned largely as a defensive standard. The 2024 amendments changed that. Section 319(2) of the EP Act establishes that a person commits an offence if the person contravenes the general environmental duty and the contravention causes, or is likely to cause, serious or material environmental harm. While a client may separately pursue a professional negligence claim against your firm for allegedly deficient advice, the immediate threat is direct statutory prosecution by the regulator. The stakes are significant. Section 319(2) of the EP Act carries a maximum penalty of 4,500 penalty units or two years' imprisonment where the offence is committed wilfully, and 1,655 penalty units otherwise. At the Queensland penalty unit value of $172.70 that applies from 1 July 2026, that is $777,150 and about $285,800 respectively. For a body corporate, section 181B(3) of the Penalties and Sentences Act 1992 (Qld) generally allows a court to impose a maximum fine of up to five times the individual maximum. ^pFirm principals should also note section 493 of the EP Act. If a corporation commits an offence against the Act, each of its executive officers also commits an offence of failing to ensure the corporation complied, carrying the maximum penalty that applies to an individual. It is a defence for an officer to prove that they took all reasonable steps to ensure compliance or were not in a position to influence the corporation's conduct in relation to the offence. The 2024 amendments turn the general environmental duty in Queensland from a guiding principle into a direct statutory offence where a breach causes, or is likely to cause, serious or material environmental harm. This gives the Queensland Department of the Environment, Tourism, Science and Innovation (DETSI) a direct prosecution pathway against any person whose activity causes, or is likely to cause, serious or material environmental harm without all reasonably practicable measures being taken. Whether preparing compliance advice is itself "carrying out an activity" for this purpose has not been tested, but the risk that a regulator will argue it is explains why you need to separate your advisory role clearly from the client's physical site operations. Establishing the Boundary Between Consultant Advice and Site Execution Expert insight: Section 319(1) of the EP Act puts the general environmental duty on every person carrying out an activity that causes, or is likely to cause, environmental harm. In practice, though, investigators rarely start with the statute. They start with the documents. After a TEP breach, the first request usually covers the whole project file (draft versions, email chains, meeting notes), not just the approved TEP. What investigators are looking for is the gap between what the TEP said would happen and what actually happened on site. Say the TEP committed to weekly bund inspections and the site logs show three inspections in two months: the failure tends to sit with the operator. But if the TEP specified a bund capacity that was never adequate for the site's catchment, the focus can shift to whoever designed that measure. Wording matters more than most consultants expect. A TEP written in the passive voice ("the bund will be upgraded", "monitoring will be undertaken") leaves open who was responsible. Investigators may read that ambiguity against the party with the technical expertise. When each action names the operator as the responsible party, it is much harder to recast after the event. Often the most damaging documents are the consultant's own emails. A message to the client saying "we'd normally recommend a larger buffer, but this should get through approval" can do more to show that a reasonably practicable measure was identified and not adopted than any expert report. If a client rejects a recommendation on cost grounds, put in writing at the time both that you made the recommendation and that the client declined it. Cost is a legitimate consideration: section 319(4)(e) of the EP Act requires regard to be had to the financial implications of different measures, so a client's decision to decline a measure on cost grounds is not automatically a breach. The regulator will, however, expect to see that the decision was made knowingly, and your written record is what shows it. Finally, if your firm’s methodology was sound but the client departed from it, you need to be able to prove that departure. Site variation notices, change requests and operator instructions to scale back works are what separate advice from execution. Without them, your firm is more exposed to being drawn into an environmental prosecution in Queensland, even where the advice itself was defensible. The First Seven Days After a TEP Breach: A Response Timeline Consider a scenario where a primary containment bund fails at 2 am on a Sunday. Later that day, well inside the 24-hour window for written notice, the operator notifies DETSI. In a scenario like this, authorised officers may attend the site within days and ask for copies of the TEP and associated engineering reports. At the same stage, the client's legal advisers are likely to be reviewing the consulting agreement for time bar clauses or indemnity provisions, preparing to deflect liability. Because DETSI will assess whether all reasonably practicable measures were taken (see the Information Sheet – General Environmental Duty (ESR/2024/6837)), the consultant should secure its project files straight away and be ready for a formal written requirement to provide documents or information within the first week. The "Ought Reasonably to Have Become Aware" Trap During Site Investigations The same exposure can arise earlier, before a TEP is drafted. Suppose your field team is carrying out a limited-scope contaminated land assessment and notices signs of an active problem, such as fresh staining below an operating tank or a leaking drainage line, in an area your scope of services expressly excluded. The client asks you to leave it alone and keep the findings confidential. You may now be caught between the client's demand for discretion and an objective statutory reporting duty. Here's how that duty works, when it is likely to reach your firm, and why a confidentiality clause won't protect your firm if it does. Section 320A's Objective Standard for Triggering the Duty to Notify Section 320A of the EP Act sets out when the notification duties in Chapter 7, Part 1, Division 2 apply. The operative duties are in the provisions that follow it, and they are triggered by what a person actually knew or ought reasonably to have become aware of. Actual knowledge is not required. The 2024 amendments expanded the duty to notify environmental harm in Queensland. Under section 320A(1)(a) of the EP Act, the notification duties apply if a person, while carrying out an activity, "becomes aware, or ought reasonably to have become aware, that an event has happened that causes or threatens serious or material environmental harm because of the person's or someone else's act or omission in carrying out the primary activity or another activity being carried out in association with the primary activity". This shift adds an objective standard to the existing actual knowledge test. The words after the awareness test matter. The duty is clearly engaged where the event arises from your own site work, for example where drilling breaches a contaminated layer or damages a tank. It is arguably engaged where the event arises from the client's ongoing operations on the site and those operations can be said to be carried out in association with your investigation. It is much less likely to capture historical contamination caused by past activities unconnected with your engagement. ^where the duty applies, who must notify whom depends on how the work is engaged. A person carrying out the primary activity "during the person's employment or engagement by, or as the agent of, someone else" must notify that other person (the "employer") within 24 hours or give the administering authority written notice if the employer cannot be contacted (section 320B). An employer that has been notified must then give the administering authority written notice within 24 hours and notify affected owners and occupiers (section 320D). For a consulting firm, this can be read two ways. If the firm's own field employee reports the event, the firm is arguably the notified employer and must itself notify DETSI under section 320D. But because the firm is itself "engaged by" the client, it may instead be treated as a person whose duty is only to notify the client, leaving the section 320D obligation to notify DETSI with the client. The Act does not say which reading applies, and we have not identified a decision on the point. The prudent course is to assume the firm may have to notify DETSI directly within 24 hours and, at a minimum, to notify the client in writing within that time. Each duty is subject to a "reasonable excuse" exception, but a client's instruction to stay silent should not be assumed to qualify. The duties do not apply to an event that is authorised under, among other things, a transitional environmental program, an environmental enforcement order or an environmental authority (section 320A(4)). A containment failure that breaches a TEP will not be authorised by it, but the exclusion is another reason for a TEP to define precisely what it does and does not permit. Because the test is objective, a person cannot rely on ignorance where a competent person in their position ought reasonably to have identified the threat. DETSI's Guideline – The duty to notify of environmental harm (ESR/2016/2271) explains how the department applies the duty. There is also a civil side. If your team walks past obvious indicators and says nothing, the client or a later purchaser may frame the omission as a failure to identify contamination, a common basis for contaminated land assessment negligence claims. Separately, historical contamination is dealt with mainly by section 320A(2). That subsection applies to the owner or occupier of land, an auditor performing a function mentioned in section 568(b), and a rehabilitation auditor, where they become aware, or ought reasonably to have become aware, of a hazardous contaminant on the land that is causing, or is reasonably likely to cause, serious or material environmental harm, or of a notifiable activity carried out on the land. Unless your firm is acting as an auditor, the person most likely to hold that duty is the client, as owner or occupier, and notification can lead to the site being recorded on the Environmental Management Register. How the Expanded Duty Overrides Contractual Client Confidentiality Warning: A confidentiality clause cannot require your firm to break the law. Where the notification duty applies to your firm, it overrides private contractual confidentiality provisions, so a consulting firm cannot legally agree to conceal a reportable event. If a client relies on the engagement letter to demand silence and your firm goes along with it, the firm may face its own, independent liability under the EP Act. Where the duty sits with the client instead (for example, as owner or occupier under section 320A(2) of the EP Act), record in writing that you have drawn the client's attention to it. If a client is pressing you to bury adverse findings, promptly seek independent commercial law advice so you can meet your reporting obligations while managing any good faith obligations you owe the client. Documenting Knowledge Boundaries During TEP Preparation Expert insight: When DETSI alleges that a consultant ought reasonably to have become aware of contamination, the argument usually turns on what the field team saw, not what the scope said. The scope of services limits what you were paid to investigate. It does not limit what a competent professional standing on the site would be expected to notice. A common mistake is leaning on generic report limitations, such as "subsurface conditions may vary between sampling locations", to cover specific access problems. That kind of boilerplate may carry little weight against a photograph of stained soil or a stockpile nobody tested. Limitations need to be specific to the site and traceable back to the field record. These documentation steps tend to hold up under scrutiny: Mark restricted areas on the site plan on the day. Record who restricted access, the reason they gave, and the time. Photograph the edge of what you could access, not just the sampling points. Save the images to the project file straight away, not a staff member's personal phone. Confirm the restriction by email to the client the same day. That way the constraint sits in a document the client received and did not dispute. Carry each restriction into the report's limitations section by location. Don't fold it into a general caveat. Field notes cut both ways. A note reading "strong hydrocarbon odour near former tank pit — outside scope" shows awareness. If nothing follows it, that note may become the centrepiece of a failure-to-notify allegation. Every out-of-scope observation should go to a senior practitioner the same day. That person makes and records a decision on whether the notification threshold is met, bearing in mind the 24-hour timeframes in sections 320B and 320D of the EP Act. Don't amend field notes after the event. Late additions can usually be detected through file metadata, and one altered record can damage the credibility of every other document on the file. If a client deliberately blocks access to avoid a finding, whether that conduct amounts to a repudiation of a contract is a separate commercial question. The more pressing point is to document both the obstruction and your response to it. Both may bear directly on what your firm ought reasonably to have become aware of. The Interaction Between Environmental Enforcement Orders and Pass-Through Claims Pass-through claims are the second front. When DETSI issues an Environmental Enforcement Order (EEO), your client must comply with it, often at significant and unbudgeted cost. Non-compliance is a separate offence: wilfully contravening an order issued on a prescribed ground, which includes grounds involving serious or material environmental harm, carries a maximum penalty of 6,250 penalty units or five years' imprisonment (section 369A(1) of the EP Act). The client's natural next step is to ask who else should pay, and the firm that wrote the compliance advice is an obvious candidate. The new polluter-pays duties make this more likely, because they increase the costs a client may try to recover from you, and ultimately from your professional indemnity insurance. Why Consolidated EEOs Are Likely to Accelerate Professional Negligence Allegations When a client faces severe financial liability under an Environmental Enforcement Order, they may attempt to offset remediation costs by pursuing a professional negligence claim against the environmental consultant whose advice they relied upon. The 2024 amendments streamlined the regulatory toolkit by replacing environmental protection orders, direction notices and clean-up notices with a single Environmental Enforcement Order (EEO). Because an EEO can require prompt and costly compliance action, clients facing large, unbudgeted costs often look to recover them through a different route: civil litigation. If the client can establish that the consultant’s original site suitability statement or compliance strategy was defective, it is likely to bring a professional negligence claim against the environmental consultant, alleging that it would not have incurred the EEO costs but for the consultant's deficient advice. That claim has to be framed in contract or negligence. Section 24(3) of the EP Act provides that a breach of the general environmental duty or the duty to restore the environment "does not, of itself, give rise to a civil right or remedy", so a client cannot sue simply because a statutory duty was breached. Instead, the EEO and restoration costs are claimed as loss flowing from the consultant's alleged breach of its contractual or common law duty of care. The Section 319C(2) Statutory Duty to Restore the Environment The 2024 amendments also introduce a positive duty that can increase what is at stake in a claim against an environmental consultant, indirectly, through the costs the client must bear. Section 319C(2) of the EP Act establishes the duty to restore the environment: "The person must, as soon as reasonably practicable after the incident happens, take measures, as far as reasonably practicable, to rehabilitate or restore the environment to its condition before the harm". This provision, inserted by the Environmental Protection (Powers and Penalties) and Other Legislation Amendment Act 2024 (Qld), gives statutory effect to the "polluter pays" principle, which the same Act wrote into the EP Act's administering principles in section 6A(1)(a)(iv). Under section 319C(1) of the EP Act, the duty applies to a person who causes or permits an incident involving contamination of the environment that results in unlawful environmental harm. The duty is qualified: restoration measures must be taken as soon as reasonably practicable, and only as far as reasonably practicable. In deciding what measures are required, regard must be had to matters such as the nature and extent of the harm, the current state of technical knowledge for remedial measures and the financial implications of different measures (section 319C(4)). Contravening the duty is itself an offence where the contravention relates to serious or material environmental harm, with the same maximum penalties as the section 319(2) offence (section 319C(3)). The cost of meeting the duty falls on the person who owes it, and it may be substantial (see the Information sheet – Duty to Restore the Environment – Overview (ESR/2024/6836)). For the consulting firm, this means a pass-through claim from the client is likely to seek to recover those restoration costs as well, significantly increasing the financial stakes of a negligence dispute. The Limitations of Indemnity Clauses Against Statutory Environmental Liability Warning: An indemnity or limitation of liability clause in an environmental consultant's engagement terms is intended to cap the firm's financial exposure to the client. It cannot, however, displace the section 319(2) offence, because a contract cannot exclude or transfer criminal liability under a statute. If DETSI considers that a consultant's deficient advice or systems contributed to serious or material environmental harm, the firm may face prosecution regardless of any civil indemnities provided by the client. Relying on a commercial indemnity to deflect regulatory attention is often a fatal miscalculation, and firms facing joint civil and regulatory action should engage a Queensland litigation lawyer early to manage these concurrent risks. Structuring Consultant Defences Against Regulatory Escalation If DETSI's investigation does turn to your firm, two statutory protections matter most: a charging bar introduced by the 2024 amendments, and a long-standing defence based on compliance with the general environmental duty. Neither will help unless your file supports it. Leveraging Section 319B(2) Protections Against Alternative Charging Section 319B(2) of the EP Act prevents a person who is charged with an unlawful environmental harm (or related) offence, and who intends to rely on the section 493A(3) defence, from also being charged with the section 319(2) offence as an alternative for the same, or substantially the same, conduct. For consultants facing an environmental prosecution in Queensland, section 319B(2) is an important but conditional safeguard. It applies only where the three conditions in section 319B(1) are met: the conduct is a "relevant act" under section 493A(1) (such as an act causing serious or material environmental harm), the person is charged with an offence for that conduct, and the person intends to rely on the section 493A(3) defence. In that situation, "the person may not be charged with an alternative offence against section 319(2) in relation to the same, or substantially the same, conduct as the relevant conduct". The practical effect is that a defendant who answers an unlawful harm charge by proving compliance with the general environmental duty cannot then be met with a section 319(2) charge in the alternative for the same conduct. Section 319B(3) adds a related protection: information obtained from the person in relation to the section 493A(3) defence in that proceeding cannot be used against them in a section 319(2) prosecution for the same, or substantially the same, conduct. Neither subsection stops DETSI from charging the section 319(2) offence in the first place. Where they apply, however, the regulator needs to decide at the outset which offence best fits what happened, and a defendant can run the section 493A(3) defence without that evidence being turned against it in a later section 319(2) prosecution. Using the Section 493A(3) Compliance Defence in Advisory Roles While the 2024 amendments created new offences, the long-standing section 493A(3) defence under the EP Act remains important for environmental consultants. It is a defence to a charge of unlawfully doing a "relevant act" under section 493A(1), which includes an act causing serious or material environmental harm or an environmental nuisance. The defendant must prove both that the act was done while carrying out an activity that is lawful apart from the EP Act, and that the defendant complied with the general environmental duty. The defence answers unlawful harm charges, not the section 319(2) offence itself. If DETSI instead charges under section 319(2), the prosecution must prove that the duty was contravened, and the firm's position rests on showing that its advisory work met the standard of "reasonably practicable measures" or that the section 319(3) exception applies. Either way, the evidence the firm needs is the same. Firms advising on activities involving a relevant industrial chemical should also check section 319A, which the note to section 493A(3) flags as relevant to the defence. A robust internal QA/QC process, peer-reviewed methodology, and clear documentation of regulatory engagement can demonstrate that the firm fulfilled its duty, shifting the focus back onto the client's failure to properly execute the approved advice. Defensive Drafting Tactics for Transitional Environmental Programs A carefully drafted TEP and environmental consulting agreement become key evidence separating your advice from the client's execution. The drafting also matters for a second reason. Under section 319(3) of the EP Act, a person does not commit the section 319(2) offence where the contravention arises only because of an act that is authorised by a transitional environmental program (one of the instruments listed in section 493A(2)), and the program provides for reasonably practicable measures to be taken in relation to that act. Compliance with an applicable code of practice has the same effect. A TEP that specifies those measures precisely, and names who must take them, gives conduct carried out in accordance with it the best chance of falling within that exception. The exception will not assist where the harm results from a departure from the program. To insulate the firm from operational failures, adopt these protective drafting measures: Explicitly allocate operational control: The TEP must clearly state that the client retains sole authority and responsibility for implementing the infrastructure changes and daily site management required by the program. Define strict scope limitations: Document exactly which physical areas and processes the firm assessed, and expressly exclude components outside that scope from any compliance certification. Document client constraints: Record any instances where the client refused recommended sampling, restricted site access, or ignored initial compliance warnings prior to the TEP submission. Establish communication protocols for non-compliance: Require the client to notify you in writing, immediately, if it departs from the TEP methodology. That lets the firm issue a written non-conformance notice, recommend corrective action or withdraw its support before harm occurs. If the client disputes the notice, the dispute resolution clause in your agreement governs what happens next, ideally a staged process that ends in alternative dispute resolution in Queensland. Conclusion The scenario of a client's facility failing and breaching a newly drafted TEP is no longer just a commercial crisis—under the 2024 amendments to the Environmental Protection Act 1994 (Qld), it is a potential criminal exposure. We have seen how section 319(2) turns the general environmental duty from a standard used mainly in defence into an offence DETSI can prosecute directly. We have also examined how the objective "ought reasonably to have become aware" standard applied by section 320A can require consultants to prioritise statutory notification over client demands for confidentiality, and how the "polluter pays" duty to restore can rapidly escalate the financial stakes of a pass-through professional negligence claim. Standard indemnity clauses can't carry that weight on their own. When a client’s operational failure causes serious environmental harm, the operator will usually be the regulator's first focus. But if the harm can be traced to a measure your firm designed, the regulator may examine the compliance advice behind it just as closely. You can't control how your client runs its site, but you can control what your file shows. This week, pull out your current TEP template and standard environmental consulting agreement and check four things: whether every action names a responsible party, whether operational control sits expressly with the client, whether confidentiality gives way to statutory reporting duties, and whether your statutory notification and PI notification processes could meet a 24-hour deadline on a Sunday. Merlo Law advises Queensland environmental consultants on TEP drafting, consulting agreements, regulatory investigations and pass-through claims. If you'd like your TEP templates and engagement terms reviewed, or you've just learned that a site you advised on has had an incident, contact John Merlo to discuss your next steps. FAQs What is the new general environmental duty offence in Queensland? Under section 319(2) of the Environmental Protection Act 1994 (Qld), it is now a direct criminal offence to contravene the general environmental duty if that breach causes, or is likely to cause, serious or material environmental harm. This 2024 amendment means the duty is no longer just a guiding principle: its breach can now be prosecuted as an offence carrying substantial maximum penalties. The duty is qualified by what is reasonably practicable, so it is not a strict liability offence. Whether a consultant's advice can itself amount to carrying out an activity that breaches the duty has not yet been tested, but consultants should expect regulators to examine advice that underpins a failed control measure. When is an environmental consultant required to notify DETSI of contamination? Section 320A of the EP Act applies the notification duties where a person carrying out an activity "becomes aware, or ought reasonably to have become aware" of an event causing or threatening serious or material environmental harm because of an act or omission in carrying out that activity or an associated activity. The standard is objective, so a consultant can be liable for failing to report an event it ought reasonably to have recognised, even in an area excluded from its scope. The duty is most clearly engaged by events arising from the consultant's own site work. Historical contamination is dealt with mainly by section 320A(2), which applies to owners, occupiers and auditors rather than to consultants generally. Can a client confidentiality agreement prevent me from reporting environmental harm? No. Once the duty is triggered, the statutory obligation to report environmental harm under Chapter 7, Part 1, Division 2 of the EP Act overrides private contractual confidentiality clauses. If a client attempts to enforce silence regarding a reportable event, capitulating may expose your firm to prosecution if the firm itself holds a duty to notify the regulator. In some engagements, the firm's duty may instead be to notify the client within 24 hours, and the client's own demand for silence does not relieve the client of its duty to notify DETSI. How does an Environmental Enforcement Order impact a consulting firm? An Environmental Enforcement Order (EEO) requires the recipient, often the operator, to take the action it states, which may include prompt and costly remediation. Contravening an EEO without a reasonable excuse is itself an offence (section 369A). Because these orders can create significant financial pressure, clients may attempt to pass those costs on to their environmental consultants via professional negligence claims, alleging the consultant's prior site advice or compliance strategy was defective. What is the statutory duty to restore the environment? Section 319C(2) imposes a positive duty on a person who causes or permits an incident involving contamination of the environment that results in unlawful environmental harm to take reasonably practicable measures to rehabilitate or restore the environment to its pre-incident condition. This embeds the "polluter pays" principle into law and can significantly increase the potential damages a client might seek to recover from a consultant in a civil dispute. Can I rely on my limitation of liability clause if DETSI investigates my firm? While a limitation of liability clause is designed to cap your financial exposure in a civil dispute with a client, it has no effect on a prosecution brought by the regulator. Contractual indemnities cannot extinguish statutory criminal liability under the EP Act. If DETSI determines your firm breached the general environmental duty, you may face prosecution regardless of any commercial protections in your engagement letter.

Key Takeaways Engage a construction lawyer in NSW as soon as any one of five gates is open. Seriousness alone is not the test. If a statutory clock is running, act first. A payment schedule under section 14 of the Building and Construction Industry Security of Payment Act 1999 (NSW) ("SOP Act"), or a statutory demand's 21-day window, can decide the outcome regardless of the merits. Get advice before any step you can't reverse: terminating, suspending, calling security or changing site locks. Getting advice afterwards usually costs more. If no gate is open, keep managing internally, but do it to a litigation standard: give notices on time, reserve rights in writing and preserve records. A payment claim, a show cause notice or a letter on a solicitor's letterhead has landed. You now have to decide whether it justifies legal cost or whether your team should keep handling it. In NSW the answer is a threshold test, not a gut feel. If any one of five gates is open, engage a construction lawyer now. If none is open, keep managing it internally, with discipline, and re-test each week. Most construction disputes never need a lawyer at all. The ones that do usually needed one earlier than the business realised. The five gates below are designed to catch that moment. The threshold test: when a construction lawyer in NSW is worth the cost How serious a problem feels is a poor guide, because the size of a dispute rarely matches its legal risk. A $30,000 payment claim with a statutory clock attached can be more dangerous than a $300,000 variation argument still going through the contract's own process. The better question is what happens if you get the next step wrong. You need advice when that next step is governed by a statute, a strict deadline or a rule that can't be undone. Apply the test as a checklist. One "yes" is enough. The five gates on a NSW project Five gates, and any one of them is enough. They are ordered the way they usually present: the clock first, because it is the one that cannot be negotiated afterwards. Gate 1: a clock is running Some NSW deadlines decide the result no matter who is right. A payment claim under the SOP Act must be answered with a payment schedule. The deadline is the earlier of the time the contract allows and 10 business days after service (s 14). If you miss it, or serve a schedule without proper reasons, you are generally stuck with the reasons you actually stated, or with none. Early payment claim advice is cheaper than an adjudication fought with no defences. The Fair Trading and Building Legislation Amendment Act 2026 (NSW), assented to on 14 August 2026, will rename the SOP Act's "business days" as "working days". The definition itself does not change: both exclude weekends, public holidays and 27 to 31 December. The change starts on a date to be proclaimed and, as at 29 September 2026, had not commenced. Either way, the count of days is the same. Other clocks in this gate: Contract time bars. Notice periods for variations, extensions of time and latent conditions are often enforced strictly. Limitation periods. Section 14 of the Limitation Act 1969 (NSW) gives six years for most contract and tort claims. Home building warranties. Under s 18E of the Home Building Act 1989 (NSW), the warranty period is six years for a major defect and two years for other defects. Warning: A creditor's statutory demand under the Corporations Act 2001 (Cth) gives the company 21 days from service. An application to set it aside, with a supporting affidavit, must be filed and served within those 21 days (s 459G). The High Court held in David Grant & Co Pty Ltd v Westpac Banking Corporation [1995] HCA 43 that no court can extend that period. If one has been served, this gate is open today. Read the guide to setting aside a statutory demand in NSW construction. Gate 2: a document with legal effect has arrived Some documents change your legal position simply by arriving: a payment claim under the SOP Act an adjudication application a statutory demand a notice to show cause or a notice of default a notice of dispute that starts a contractual escalation clause a bank guarantee call an NCAT application a rectification order from Building Commission NSW a notice from SafeWork NSW after an incident a statement of claim starting court proceedings The problem is rarely that nobody reads these. It's that the wrong person reads them, too late. Practice note: Adjudication files are seldom lost because the respondent had no answer. They're lost because the answer never made it into the payment schedule. "Defective works, amount withheld" was on time, but it was hollow. The respondent is generally confined to the reasons it gave, so a set-off worth real money disappears. The hour spent getting the schedule right is the cheapest legal spend on the project. Gate 3: your next step can't be undone Get advice before you do any of the following: terminate suspend work call security change the site locks bring in a replacement contractor send an email admitting fault A termination that doesn't follow the contract's show cause process can be treated as repudiation. That turns you from the innocent party into the defendant. Suspension for non-payment under the SOP Act needs a notice of intention that states it is made under the Act, and then two business days before work stops (s 27(1)). An application to restrain a bank guarantee call has to be made before the bank pays. The 48-hour dispute triage sequence for NSW construction explains why these steps come first. Gate 4: the exposure is material to the business There is no universal dollar figure. The threshold is whatever amount would affect your cash flow, your contractor licence, your Home Building Compensation Fund position or your ability to tender. Look at the recovery-adjusted value, not the face value. That is the amount you would realistically collect or lose once costs, delay and the other side's ability to pay are taken into account. A claim that looks large against a counterparty with no assets may not justify the expense. A modest claim that sets a precedent for twelve other subcontracts may. Gate 5: the other side's behaviour has changed The balance shifts in a construction dispute when the other side: starts writing through solicitors stops answering the phone changes its registered office moves work to a new ABN registers security interests in favour of related parties Each of these signals that the matter is moving from a commercial argument to a legal one, and possibly to a solvency problem. At that point every week you wait weakens your position. Engage now or keep managing: a decision table Situation Keep managing internally Engage a lawyer now Variation disagreement Contract process running, notices given on time Time bar close or missed; claim rejected outright Slow payment No dispute raised; pay history consistent SOP payment claim or schedule in play; excuses changing Defect complaint Minor, within the defects liability period, being rectified Owner is threatening NCAT or has a consultant's report Poor performance Addressed through program meetings You're considering a show cause notice or termination Counterparty conduct Normal contact continuing Solicitor's letter, silence or solvency warning signs What you can safely keep managing internally Many contract disputes are resolved inside the contract without any lawyer. Keeping it internal is legitimate, but only if you manage it as though a court might read your file later. That means: giving every notice within its contractual period reserving your rights in writing framing internal views on fault as provisional keeping site diaries, programs and text-message instructions with their metadata intact That is dispute avoidance in practice, and it makes any later escalation cheaper. The wider framework is covered in commercial litigation in NSW. Practice note: A well-run internal file isn't wasted if the matter escalates later. Your lawyer can take it over efficiently. The expensive files are the ones where the business managed the dispute informally for months. Instructions were given by phone, the project inbox was shut down at close-out, and the site engineer's phone was wiped. The evidence that would have settled the dispute is gone before anyone thinks to call a lawyer. Re-test against the five gates every week, and immediately whenever a new document arrives. Conclusion The decision to hire isn't about how angry the dispute makes you or how large the number looks. It's about whether a clock, a document, an irreversible step, a material exposure or a change in behaviour has moved the matter beyond internal management. Construction dispute resolution in NSW rewards businesses that recognise that moment early. How Merlo Law can help Merlo Law acts for NSW directors, principals, head contractors and subcontractors on the decisions this guide covers. Where a clock is running, we take the deadline off your desk first — reviewing the payment claim, the show cause notice or the statutory demand, and putting the response in a form that preserves your position. Where a document has arrived, we tell you what it changes and what it does not. Where your next step cannot be undone, we advise before you take it rather than after. We also work the other way. If none of the five gates is open on your project, we will tell you that, and help your team keep managing the matter internally to the standard that protects you if it escalates later. The time to call is when a gate opens, not when the dispute becomes unmanageable. The steps that decide these files are usually taken in the first days, and advice before those steps is generally less costly than correcting them afterwards. The same threshold test applies whether the matter ends in adjudication, NCAT or the Supreme Court. If you are not sure whether a gate is open, that question on its own is worth a conversation. Speak with our Sydney construction lawyers, or call the office to arrange a time. FAQs When should I hire a construction lawyer in NSW? When any one of five gates is open: a statutory or contractual clock is running; a document with legal effect has arrived; your next step can't be undone; the exposure is material to the business; or the other side's behaviour has changed. If none is open, you can usually keep managing internally. Is it too early to involve a lawyer in a NSW construction dispute? Rarely, if a gate is open. The first documents often decide the file. A payment schedule, for example, generally limits the reasons you can rely on at adjudication. What happens if I miss a payment schedule deadline in NSW? Under the SOP Act, a respondent that doesn't provide a payment schedule in time becomes liable to pay the claimed amount on the due date (s 14(4)). If the claimant sues for it as a debt, the respondent can't raise contractual defences or cross-claims (s 15(4)). If the claimant chooses adjudication instead, it must first give notice, and the respondent then has one further chance to provide a payment schedule within 5 business days (s 17(2)). Without a schedule, the respondent can't lodge an adjudication response (s 20(2A)). Do I need a lawyer to respond to a statutory demand in NSW? A set-aside application must be filed and served, with a supporting affidavit, within 21 days of service, and that period can't be extended. Because a missed deadline can't be cured, get advice as soon as the demand is served. Should I get legal advice before terminating a construction contract in NSW? Yes. A termination that doesn't comply with the contract's notice and show cause process can amount to repudiation, which exposes you to the other side's damages claim.

Key Takeaways Send the raw bundle, not a summary. The contract as signed, the payment claim exactly as served, any payment schedule and its date of receipt, the complete email transmission record — in the order they were created, plus one page of dates. Freeze your communication. Every message you send to the other side before taking advice becomes evidence you cannot retract. Stop writing today. If you are the respondent, your payment schedule is your only chance to raise reasons. Section 20(2B) of the Building and Construction Industry Security of Payment Act 1999 (NSW) (SOP Act) generally stops you adding a reason for withholding later, and one-line reasons are usually lost. Diary each deadline from the earliest date the document could arguably have been received, not from a later date a deeming clause might support, and do not serve a second payment claim for the same named month unless the contract expressly allows it. The First 24 Hours Decide More Than You Think You have just been served with a payment claim you believe is wrong — or you served one and the payment schedule has come back short. In the next 24 hours you will not win or lose this dispute on the law. You will lose it by sending one more email, tidying up one more project inbox, or serving one more claim. The job tonight is not advocacy. It is preservation, and the fastest way to start is to get early construction payment dispute advice on the raw file before anyone on your side writes anything else. This is what to preserve, what to send, and what to stop doing today under the SOP Act. Two dates control everything that follows, and neither is the date printed on the document. The first is the date the payment claim or payment schedule was actually received — not sent, and not the date a contractual deeming clause says it was received. The second is the date the construction contract was entered into. Contracts entered into on or after 21 October 2019 are governed by the monthly claim-entitlement rules in section 13(1A)–(1B) of the SOP Act. Contracts entered into before that date are still analysed under the former reference-date framework, where entitlement disputes are far more common. Get this fork wrong and an otherwise strong position can die on jurisdiction before anyone argues the merits. Two dates, one diary entry Write both dates down now, then work forwards. Section 14 gives a respondent the time set by the contract, or 10 business days after the claim is served — whichever expires earlier — to serve a payment schedule. Section 17 gives a claimant 10 business days after receiving a payment schedule showing a shortfall, or 20 business days after the due date where a scheduled amount is not paid, to lodge an adjudication application. Where no payment schedule was served, the claimant must first give a section 17(2) notice within 20 business days after the due date, which gives the respondent a further 5 business days to serve a schedule. These two windows are why tonight matters more than next week. Why the clock starts at receipt, not at sending That distinction is not theoretical. Where a claim is emailed as a link rather than an attachment, the respondent often argues the clock only started when the file was opened — and a payment schedule that lands "one day late" on the claimant's calculation can be argued to be on time on the respondent's. The party who can prove the actual moment of receipt, from the email header and the message metadata, is the party who controls the timeline. That is why the transmission record is the first document a lawyer asks for, and why it is the first thing you should preserve. Practice note: The most common service dispute in NSW arises when a claimant emails a payment claim as a link rather than an attachment. If you are the claimant, you carry the burden of proving service. If you are the respondent, do not plan your payment schedule around a late-receipt argument: count from the earliest date the claim could arguably have been received, because a schedule found to be late leaves you liable for the full claimed amount under section 14(4). Either way, the first thing a lawyer needs is the transmission record — the header, the timestamp, the addresses, the attachment itself. Send that tonight. What to Preserve, and What to Send, Tonight The answer to "what do I send?" is more boring than most contractors expect: send the raw bundle. Not a summary. Not a chronology written from memory. Not screenshots. The actual files in the order they were created, plus one page of dates. Preservation means three specific things: do not delete, do not edit, do not overwrite. That includes the email thread, the project messaging, the site diary, the variation instruction and any superseded version of a document. Where a document exists in two forms, keep both — the earlier version is often what proves what was known, and when. The bundle to preserve and send Preserve this Because it decides The construction contract as signed, plus every variation and instruction Which claim-timing regime applies and what the parties agreed The payment claim exactly as served Whether the section 13 elements and the statutory endorsement are present Any payment schedule you served or received, and its date of receipt Default liability, and what reasons are still available later The complete email transmission record, incl. headers and all project addresses Valid service — usually the first jurisdictional battleground Your licence details and any Home Building Compensation Fund position evidence Whether you can recover for residential building work under the Home Building Act 1989 (NSW) Retention and trust records, where the project is qualifying Exposure if the party above you fails — see the Security of Payment Regulation 2020 (NSW), and whether the SOP Act applies at all (it does not apply to a contract with an owner who lives, or proposes to live, in the premises) The site diary, program and payment ledger Commercial context the other side will characterise for you If you are unsure what in your particular file qualifies, that is the point at which early construction law advice is worth more than another weekend of drafting. Service records — the evidence most claimants lose The transmission record is the item most often incomplete by the time a lawyer sees the file, because it lives in someone's inbox rather than the project folder. Preserve the sent item, the received item, the delivery and read receipts if they exist, and every address the claim was sent to — the nominated contractual address, the address used in ordinary project correspondence, and any address adopted by conduct across the project. If multiple addresses were in play, the record of which one was used, and when, is itself the evidence. How to send it One email. Raw files attached — PDFs where they are already PDFs, otherwise native format. One page of dates: contract date, claim served date, schedule served date (if any), due date, today's date. No commentary, no admissions, no narrative of the dispute. The Communication Freeze For the next 24 hours, assume every message you send to the other side will be read aloud later by someone who is not on your side. That is not paranoia — it is how these files are actually run. Stop the informal channel. No "we'll sort it out between us" emails. No undertaking to accept a reduced amount. No confirming a variation was approved when you are not certain it was. Unless a message is a genuine settlement communication that your lawyer has helped you frame as without prejudice, assume nothing you write now is confidential and nothing you write now can be withdrawn. Practice note: Adjudicators work to tight statutory timeframes and will not do your work for you. That cuts both ways: a claimant cannot rely on the adjudicator to piece together a claim that was never properly described, and a respondent cannot rely on the adjudicator to find a reason for withholding that was never written down. The party whose position is properly documented in the statutory documents usually holds the advantage. Tonight is your last clean opportunity to document. Three Ways Contractors Destroy Their Own Case WARNING. Each of the moves below is made by someone who believes they are being helpful, responsive or commercial. Each one can be difficult or impossible to undo. 1. Emails that show you suspected insolvency Where a party upstream later collapses and a liquidator pursues an unfair preference claim under section 588FA of the Corporations Act 2001 (Cth), the recipient's good faith defence under section 588FG turns on whether that party had reasonable grounds to suspect insolvency, judged by what it knew and what a reasonable person in its circumstances would have suspected. Contemporaneous emails complaining that the contractor "never pays on time" or "is clearly going under" are exactly the material that defeats the defence. If the party above you is deteriorating, that is a reason to take advice — not a reason to fire off speculative commentary. Keep your records accurate and factual, and remember that not writing a suspicion down does not change what a reasonable person in your position would have suspected. Where enforcement escalates, court proceedings and the recovery strategy need to be assessed together rather than separately. 2. A second claim against the same monthly entitlement Under section 13(5)–(6) of the SOP Act, only one payment claim may generally be served in respect of each named month unless the contract expressly allows more. Serving a fresh claim for the same month to "fix" a defect is one of the fastest ways to hand the respondent a jurisdictional argument — and the new claim does not restart the clock on the original. 3. One-line reasons for withholding If you are the respondent, the payment schedule is your only clean opportunity to state why you are withholding. Section 20(2B) generally prevents you raising in your adjudication response any reason not already in the schedule. "Defective works — deduct $80,000" tells an adjudicator nothing. An item, a location, the standard breached, a quantified deduction and the supporting quote tells them everything. Running It Yourself vs Instructing a NSW Security of Payment Lawyer Running it yourself Instructing a lawyer at the 24-hour mark Best suited to A single, clearly defined claim with clean service records and a respondent who served a compliant schedule Any file where service is arguable, a jurisdictional point has been raised, or the amount is material to cash flow Main risk Missing a statutory window while working out the process — the windows are short and unforgiving The cost of advice. The statutory windows keep running while you obtain it, so send the raw bundle rather than a summary What you still must do Preserve everything and diary the dates Preserve everything and diary the dates What you should not do Correspond with the other side while deciding Correspond with the other side while waiting for advice If you want your file reviewed, contact Merlo Law and attach the bundle, not a description of it. Conclusion The first 24 hours are not about winning an argument. They are about making sure the argument is still available when you need it: the raw documents intact, the service record provable, the dates diarised, and nothing in writing you would have to explain later. Do that tonight and your position is preserved. Then decide who runs it. Speak with a NSW security of payment lawyer before you send anything further to the other side. FAQs What should I send my lawyer in the first 24 hours of a NSW payment dispute? The raw bundle: the contract as signed, every variation and instruction, the payment claim exactly as served, any payment schedule and its date of receipt, the complete email transmission record, your licence and insurance position, and your site diary and payment ledger. Attach one page of dates. Send no commentary. Do I need to send the original payment claim or just a copy? Send the exact document that was served or received, in the form it was served — including how it was transmitted. A re-typed or reformatted version cannot prove what the other side actually received, and service is frequently the first jurisdictional issue raised. Can I delete project emails after a payment dispute starts in NSW? No. Delete nothing. Correspondence, including messaging applications and superseded documents, may be evidence in an adjudication or later court proceeding, and deleting it can be more damaging than its contents. Preserve the complete thread, including headers. What happens if I serve a second payment claim for the same month in NSW? Under section 13(5)–(6) of the SOP Act only one payment claim may generally be served per named month unless the contract expressly allows more. A second claim for the same month is a common jurisdictional objection, and it does not extend the window on the original claim. How long do I have to apply for adjudication in NSW? It depends on what the respondent did. Where a schedule was served showing a shortfall, generally 10 business days after receiving it. Where a schedule was served but the scheduled amount was unpaid, generally 20 business days after the due date. Where no schedule was served, a section 17(2) notice must first be served within 20 business days after the due date. The respondent then has 5 business days to serve a schedule, and the application must be made within 10 business days after that period ends.
