Key Takeaways
Commercial promises do not pause statutory deadlines: Relying on informal assurances to "sort out the dirt quantities next month" may cause you to miss strict Building Industry Fairness (Security of Payment) Act 2017 (BIF Act) timeframes.
Validity relies on specific detail: A valid payment claim must strictly identify the construction work, state the amount, and request payment. An invoice can qualify (and is deemed to satisfy the request-for-payment element), but one that vaguely identifies the work often fails to switch on your statutory protections.
Failure to schedule creates default liability: If the respondent fails to issue a payment schedule within the required time, they may become liable for the full claimed amount, provided your initial claim was procedurally flawless.
Pay-when-paid clauses are void: Head contractors cannot lawfully withhold your progress payment simply because they have not yet been paid by the principal.
You have just submitted a major $450,000 progress claim for completed subdivision earthworks, but the head contractor’s project manager calls with a familiar excuse: they are "too busy to assess the dirt quantities right now" and promise to wrap the balance into next month's claim. You want the cash for the heavy iron you’ve had running on site all month, but you hesitate to serve formal legal notices for fear of ruining a valuable ongoing relationship. The problem is that the statutory clock under the BIF Act is already ticking, and a commercial handshake does not stop it. Relying on goodwill over strict statutory timelines forces you to decide exactly when to act before you permanently lose statutory protection for that specific claim.
The "Sort It Out Next Month" Trap: Statutory Deadlines vs Commercial Promises
At this stage, the question is whether to accept the project manager's commercial goodwill or formally trigger the statutory mechanisms of the BIF Act before your claim goes stale. The strict deadline is already ticking, and the procedural steps outlined below map out the exact timeline required to secure your right to payment while effectively managing the commercial relationship.
Separating Strict BIF Act Timelines from Contractual "Goodwill" Extensions
The civil contractor's statutory rights under the BIF Act operate entirely separately from informal contractual promises or "goodwill" extensions offered by the head contractor. A verbal assurance from a project manager that they will assess your variation next month does not legally pause the strict statutory timelines that govern payment claims and adjudication rights.
Waiting for a principal to "get around to it" is a procedural risk that frequently results in contractors inadvertently allowing their statutory payment window to close. To understand how these parallel frameworks interact and why statutory time limits take precedence over site-level arrangements, review our comprehensive BIF Act guide.
Section 68 Prerequisites: Is Your Civil Progress Claim Statutorily Valid?
To trigger your statutory protections, the progress payment claim a civil contractor submits must meet strict procedural requirements. Under section 68 of the BIF Act, a payment claim for a progress payment is a written document that must satisfy the following criteria:
Identify the construction work performed in sufficient detail.
State the claimed amount.
Expressly request payment of the claimed amount. Separately, where the claim arises under a subcontract, section 75 of the BIF Act requires the claimant to accompany the payment claim with a supporting statement—a requirement reinforced by later amendments to the BIF Act. Importantly, under section 75(8) a failure to provide the supporting statement does not, of itself, invalidate the payment claim; it is best treated as a compliance obligation rather than a condition of the claim's validity.
Identify the construction work or related goods and services to which the payment relates (not merely the work, but any related goods and services as well).
The Cost of Missing the Adjudication Application Window
Warning: Delaying action based on a promise to pay later can cause you to lose your statutory protection for that specific claim amount entirely. Under section 75 of the BIF Act, any person claiming an entitlement to a progress payment under a construction contract has a statutory right to give a payment claim to the liable party—but rigid timeframes govern both when that claim may be given and how long you then have to act on it.
The BIF Act does not require you to serve a separate "warning notice" or "second chance notice" before proceeding; instead, the critical deadline is the strict window under section 79 to lodge an adjudication application. If you let that window close because you waited for the next month's assessment, you are likely to forfeit the ability to pursue that specific progress claim through rapid statutory adjudication.
Section 76 and 77: When the Head Contractor Misses the Payment Schedule Deadline
The deadline has passed, and the head contractor has failed to issue a formal payment schedule in response to your claim. You may feel a false sense of victory assuming the cash is now guaranteed by default. While the statute is on your side, this section will detail exactly how you must navigate the procedural requirements to convert that default liability into actual cash in your account.
The Statutory Obligation to Respond Under Section 76
If a head contractor intends to pay less than the claimed amount, they cannot legally ignore the invoice. The statute imposes a strict procedural trigger on the respondent. A respondent who receives a payment claim is statutorily obligated to respond by issuing a payment schedule within strict timeframes, unless it simply pays the claimed amount in full by the due date. Ignoring the claim without paying it is not a legally viable option under the Act, and attempting to do so exposes the respondent to severe default consequences.
Under section 76 of the BIF Act, a respondent who receives a valid payment claim must issue a payment schedule within the strict statutory timeframe, unless it pays the claimed amount in full on or before the due date for the progress payment. When the head contractor’s silence causes this default, the statutory payment mechanism moves to its next phase.
Section 77 Liability: Default Entitlement Does Not Mean Automatic Cash
Expert insight: A failure to respond provides a clear statutory advantage, but it does not equate to instant money in the bank. If a respondent fails to provide a payment schedule in response to a valid payment claim, they become automatically liable for the full amount claimed under section 77 of the BIF Act. The difficulty is that the fight simply shifts ground.
Once you move to recover, the respondent's lawyers rarely argue about the earthworks. They go looking for a defect in the claim itself, because if the claim was never valid, the section 77 liability never arose.
The reference date is where they dig first. On civil jobs, contractors often serve a claim whenever the month ticks over or whenever the plant invoices land, rather than on the date the contract actually generates the right to claim. If your contract ties the reference date to a specific milestone or a set day and you served early, expect that to be raised. Two claims for the one reference date is another common trap — the second is liable to be knocked out.
The practical lesson is that the value of a default liability is only as strong as the paperwork underneath it. Before you rely on the respondent's silence, go back and confirm the claim was served on a genuine reference date, requested payment in terms, and carried a supporting statement if you were claiming as head contractor.
Adjudication Strategy: Avoiding the Jurisdiction Trap
When moving to adjudication after a schedule is missing or deficient, your primary strategic risk is not a dispute over the quality of your civil works, but a procedural technicality. In a subcontractor payment dispute, civil contractors frequently find that respondents rely heavily on jurisdictional knockouts rather than arguing the merits of the earthworks or pipe-laying performed. If the respondent can convince an adjudicator that your payment claim lacked a valid reference date under the contract, that defect can undermine the foundation of the claim and may prove fatal to the adjudication. Consequently, ensuring your initial claim's procedural perfection is often your strongest defence against these knockout attempts.
Void Defences: Pay-When-Paid Clauses and the Security of Payment Protections Under Section 200
The head contractor has finally responded, but their only excuse for withholding your progress payment is that the project principal hasn't paid them yet. You've heard this a hundred times in the civil industry, but the law treats it very differently than site-level tradition. This section provides the hard legal ammunition you need to reject that excuse and push your adjudication application forward without hesitation.
Why "We Haven't Been Paid by the Principal" Fails Under Section 74
Head contractors frequently attempt to use back-to-back flow-down clauses—commonly known as "pay-when-paid" or "pay-if-paid" clauses—to shift cash-flow risk down the supply chain. A "pay-when-paid" clause defers payment until the principal pays, while a "pay-if-paid" clause attempts to extinguish the obligation altogether if the principal never does. Both are designed to relieve the head contractor of their payment obligation and push cash-flow risk down the chain. However, the enforceability of back-to-back flow-down payment clauses is sharply limited by the BIF Act. Section 74 of the BIF Act expressly provides that a "pay when paid" provision of a construction contract has no effect in relation to payment for construction work carried out or related goods and services supplied. This is reinforced by the broader prohibition on contracting out under section 200, which provides that a contractual provision has no effect to the extent it purports to exclude, limit or change the operation of the Act.
A "pay when paid" provision has no effect in Queensland under section 74 of the BIF Act, and section 200 independently prevents parties from contracting out of the security of payment regime — the principal's delay is not the subcontractor's problem to carry.
When a head contractor relies on this defence in their payment schedule, they provide you with a straightforward path to challenge the withholding, because the clause has no effect under the Act. If you encounter this stalling tactic, speak with our team to review the schedule.
Navigating the Respondent's Jurisdictional Knockout Attempts
Expert insight: Civil contractors acting as respondents frequently try to execute an "ambush" strategy by raising new reasons for withholding payment during the adjudication process that were not included in their original payment schedule. Adjudicators are statutorily barred from considering these new reasons when assessing an adjudication application. The schedule fixes the boundaries of the fight, and the respondent is generally held to what they put in it.
In practice, a respondent who scheduled nothing but a "pay-when-paid" position, then floods the adjudication response with fresh complaints about defective pipe-laying, backfill compaction, or survey set-out, usually finds those complaints struck out as new reasons. A well-drafted response from the claimant will identify each late-raised item and invite the adjudicator to disregard it — and adjudicators, working to tight statutory timeframes, tend to take that path rather than let the scope of the dispute balloon.
The tactical takeaway cuts both ways. If you are the claimant, read the schedule line by line and hold the respondent to it in your response. If you are the respondent, understand that the schedule is your one real chance to state your reasons — a thin or lazy schedule cannot be rescued later.
Preparing Your Application for the QBCC Registry
If the payment schedule relies on void defences, or if no schedule was provided within the section 76 timeframe of the BIF Act, the next procedural step is assembling your application for the QBCC Adjudication Registry within the section 79 timeframe. Unlike issuing a statutory demand, which focuses on corporate insolvency, the adjudication pathway requires meticulous compilation of project-specific evidence. You must provide the contract, the payment claim, proof of delivery, the payment schedule (if any), and submissions substantiating the value of the civil works performed. For civil works specifically, the standard forms are the least of it — the application lives or dies on how well you evidence the quantities. Marry your claimed volumes to survey data, weighbridge dockets, machine hours, and the daily site records your operators keep, because an adjudicator valuing earthworks needs to trace the number back to something measured on the ground.
Where you have claimed variations, attach the instruction that generated the work — the RFI, the marked-up drawing, the site instruction, or the email direction — not just your own tally of extra dirt. The gap between "we moved more material" and "we were directed to move more material, and here is the direction" is often the difference between a full and a discounted determination.
Proper preparation at this stage is often best handled with guidance from a Queensland litigation lawyer whom civil contractors trust to navigate the registry requirements.
Conclusion
When that $450,000 progress claim for completed subdivision earthworks sits unpaid, relying on a project manager's promise to "sort it out next month" is a risk that can permanently compromise your statutory payment rights. You now know that the BIF Act operates on rigid, unforgiving timelines that do not pause for commercial goodwill. By understanding the strict requirements of section 68, the timeframes for giving a payment claim under section 75, the critical adjudication application window under section 79, and the reality that default liability under section 77 still requires procedural perfection to enforce, you are positioned to protect your cash flow without relying on the head contractor's administrative convenience.
You also know that common industry excuses—like "we haven't been paid by the principal yet"—have no effect in Queensland under section 74 of the BIF Act, with section 200 independently preventing contracting out of the Act. This knowledge allows you to reject stalling tactics confidently and maintain pressure on the payment chain.
The next time a head contractor attempts to delay assessment of your civil works, do not wait for the next billing cycle. Document the refusal, review the BIF Act deadlines immediately, and be ready to lodge your adjudication application the moment the statutory window opens.
If a claim is sitting unpaid right now, the clock may already be running. Have your payment claim, and any schedule you have received, reviewed before you decide your next step—so the timing works for you rather than against you. Contact our team to arrange that review.
FAQs
What makes a civil progress claim valid under the BIF Act?
A valid payment claim under the BIF Act must be in writing, specifically identify the construction work, state the claimed amount, and expressly request payment. Where the claimant is at the top of the contractual chain (typically a head contractor), section 75 also requires a supporting statement to accompany the claim; however, under section 75(8) a failure to provide one does not, of itself, invalidate the claim. Failure to meet the core section 68 criteria, on the other hand, often renders the claim invalid for statutory adjudication.
Can a head contractor delay my payment until they get paid by the principal?
No, head contractors cannot legally delay your payment based on a "pay-when-paid" clause. Under section 74 of the BIF Act, a "pay when paid" provision has no effect in Queensland, and section 200 separately prevents parties from contracting out of the Act. Relying on this excuse in a payment schedule is typically an invalid defence.
What happens if the head contractor ignores my payment claim completely?
If a respondent fails to provide a payment schedule in response to a valid payment claim, they may become liable to pay the full claimed amount under section 77. However, enforcing this default liability requires strict compliance with statutory procedures, including lodging any adjudication application within the timeframe set by section 79.
Does a verbal promise to pay next month pause the BIF Act deadlines?
No, a commercial assurance to delay payment assessment does not legally pause the strict statutory timelines that govern payment claims in Queensland. If you wait and miss your window to lodge an adjudication application under section 79, you may lose the right to pursue that specific claim through adjudication.
Can the respondent raise new reasons for non-payment during adjudication?
Generally, adjudicators are statutorily barred from considering new reasons for withholding payment that were not included in the respondent's original payment schedule. This procedural restriction prevents respondents from "ambushing" the claimant with new allegations of defective civil works late in the process.
What is the risk of using a standard invoice instead of a BIF Act compliant claim?
An invoice can constitute a valid payment claim—indeed, a document bearing the word "invoice" is deemed to satisfy the request-for-payment element under section 68(3)—but a standard commercial invoice that lacks the other section 68 requirements may fail to activate your statutory protections. Respondents often attempt to defeat adjudication applications by arguing the original invoice did not constitute a valid payment claim or lacked a proper reference date.
