Building a Scalable Preliminary Agreement System for Your QLD Project Pipeline

For the Queensland property developer, the project pipeline is everything. Yet, a critical vulnerability often exists right at the start: the early-stage engagement with builders. Too often, developers rely on inconsistent, ad-hoc preliminary agreements, letters of intent, or even handshake deals. This project-by-project approach introduces unnecessary risk, administrative drag, and the potential for costly disputes before a single sod is turned. The strategic solution is to stop creating one-off documents and start building a scalable system.  

This playbook is about creating a master Preliminary Works Agreement (PWA) framework—a repeatable, risk-managed process that standardises your builder engagements, protects your interests, and streamlines your entire development pipeline. 

By aligning this system with Queensland's unique legal landscape, particularly the regulations enforced by the Queensland Building and Construction Commission (QBCC), you can move projects from concept to construction with greater speed, clarity, and control.

Key Takeaways 

• System Over Document: Shift from creating one-off Preliminary Works Agreements (PWAs) to developing a master template that serves your entire project pipeline, ensuring consistency and control. 

• Front-Load Your Risk Management: A robust PWA system standardises critical terms like scope, cost-plus frameworks, intellectual property, and termination rights before you commit to a full construction contract. 

• QBCC & BIF Act Compliance is Non-Negotiable: Your scalable system must be built on a foundation that respects QBCC licensing rules and the payment structures mandated by the BIF Act, even at the preliminary stage. 

• Clarity Prevents Disputes: A well-defined preliminary agreement system is essential infrastructure for your development business, significantly reducing exposure to disputes and protecting your commercial position from the outset. In 2022-2023 alone, the QBCC handled 6,306 disputes—many of which could have been avoided with proper preliminary documentation in place.

Beyond the One-Off Agreement: Adopting a Pipeline Mentality 

Successful commercial development hinges on efficiency and predictability. While developers meticulously systemise financial modelling and site acquisition, the initial engagement with builders is often treated as a bespoke, one-time negotiation. This is a strategic error. Adopting a pipeline mentality means viewing these early agreements not as isolated contracts but as the first, crucial gear in a much larger machine. It requires a shift from reactive document drafting to proactive system building for all your preliminary works agreements and heads of agreement, creating a consistent framework for your entire developer project pipeline. 

The Flaw in Project-by-Project Preliminary Contracts 

Drafting a unique preliminary agreement for each new project is inherently inefficient and fraught with risk. When terms relating to intellectual property, payment structures, or termination rights differ from one project to the next, you create a portfolio of inconsistent liabilities. One poorly worded clause in an agreement for a Gold Coast high-rise can create a costly precedent that haunts a future commercial project in Brisbane.

This approach multiplies the administrative burden, increases legal costs as lawyers must re-evaluate terms each time, and opens the door to disputes arising from simple ambiguity. A non-standardised approach is a direct threat to effective risk management across your portfolio. 

What is a "Scalable System" for Builder Engagement? 

A scalable system for builder engagement is a master PWA template, or "playbook," that serves as the foundation for all your early-stage negotiations. It's more than just a fill-in-the-blanks document.

It is a comprehensive framework that includes: 

• A Core Master Agreement: Containing your non-negotiable legal protections, IP clauses, termination rights, and dispute resolution mechanisms. 

• Standardised Annexures: Schedules for project-specific details like the scope of works, budget caps, and key personnel, which can be easily adapted without altering the core legal terms. 

• A Process for Controlled Variations: Clear rules on how changes to the preliminary scope are requested, approved, and costed. 

• Consistent Cost Controls: A pre-defined approach to managing costs, whether through a capped cost-plus model or other agreed structures. 

This system is designed to be deployed across diverse commercial development projects, from multi-unit residential builds to industrial warehouses, ensuring a baseline of control and legal protection every time. 

The Strategic Advantage for Multi-Project Developers 

Implementing a scalable PWA system delivers tangible benefits to a developer's bottom line and operational efficiency. The primary advantage is a dramatic reduction in negotiation friction; builders who work with you repeatedly become familiar with your standard terms, speeding up the engagement process. This allows for faster project mobilisation.

For financiers and investors, a professional, repeatable process demonstrates robust risk management and corporate governance, strengthening your position when seeking capital. Ultimately, this system provides predictable risk exposure, allowing you to forecast legal and administrative overheads more accurately and giving you a stronger, more professional footing in every builder negotiation you enter. 

Anatomy of a Scalable Preliminary Works Agreement 

A robust PWA template is your first line of defence. It's where you define the rules of engagement, protect your most valuable assets, and create a clear exit path if the relationship doesn't proceed. The anatomy of this master document must be meticulously crafted to manage expectations and mitigate risk from day one. Key components include a precise scope of works, ironclad intellectual property clauses, and a clear contract variation process. 

Defining a Crystal-Clear Scope of Preliminary Works 

The heart of any PWA is the scope of works. Your master template should meticulously define the types of activities covered (e.g., site investigations, geotechnical surveys, design development with consultants, cost planning, programming, obtaining development approvals). Project-specific details are then handled in an annexure or schedule.

This schedule will list the exact deliverables, timelines, and personnel for that particular project, such as procuring long-lead items or preparing detailed construction drawings. Ambiguity in the scope is a primary cause of commercial building disputes. A builder might assume a task is excluded, while the developer assumes it's included, leading to conflicts over cost and time. A clear, written scope, signed by both parties, eliminates this risk. 

Protecting Your Intellectual Property and Design 

Expert Insight from John Merlo: "One of the most critical, yet often overlooked, aspects of a preliminary agreement is intellectual property. A developer can spend tens or even hundreds of thousands of dollars on design, engineering, and reports. If the agreement is silent on IP ownership and you part ways with the builder, they could potentially walk away with—and even use—the very designs you paid for. Your PWA template must be unequivocal." 

It is essential that your master agreement contains a clause explicitly stating that the developer retains full ownership of all intellectual property created during the preliminary phase. This includes architectural plans, engineering computations, consultant reports, and any other documents or data generated.

The clause should clarify that this ownership stands even if the project does not proceed to a full construction contract with that specific builder, ensuring your investment in design is protected and portable. 

Crafting Your Standardised Termination and Exit Clauses 

Not every preliminary engagement leads to a full-blown construction project. Your scalable PWA must anticipate this and provide a clean exit strategy.  

The template should include clear, unambiguous termination triggers. These could be "for convenience" (allowing the developer to terminate for any reason with notice) or for specific causes like the failure to agree on a final price for the main works contract, unsatisfactory due diligence findings, or the builder's insolvency.  

The clause must also structure the "exit payment," defining precisely how the builder will be compensated for validly performed and documented work up to the termination date.  

This pre-agreed off-ramp prevents a developer from being held hostage in negotiations for the main contract and provides a commercial, predictable process for parting ways. Having these terms clearly defined is the first step in properly terminating construction contracts. 

Integrating Cost Structures for Predictability and Control 

A scalable PWA system is incomplete without a standardised approach to costs. The preliminary phase is often filled with unknowns, making fixed-price agreements risky for both parties. Your system must integrate a cost structure that offers transparency and flexibility while giving you, the developer, ultimate control over the budget. This means establishing clear rules for everything from the builder's margin to the management of a provisional sum and prime cost items, all while ensuring every payment schedule complies with Queensland's strict laws. 

Why a Cost-Plus Framework Often Suits Preliminary Works 

For preliminary works, a well-managed cost plus contract framework is often superior to a fixed-price model. The inherent uncertainties of site investigations, design evolution, and authority approvals mean a fixed price would either be heavily inflated by the builder to cover their risk or be unrealistically low. A cost-plus arrangement, where the developer pays the actual costs incurred plus an agreed margin, provides transparency and adaptability. However, this must not be an open chequebook. Your PWA template must enforce strict controls, including a guaranteed maximum price or cap, clear definitions of what constitutes a reimbursable cost, and the developer's right to audit all expenses and invoices. 

Managing Provisional Sums and Prime Cost Items 

Even within a cost-plus framework, some costs are unknown. This is where Provisional Sums (allowances for work yet to be detailed, like landscaping) and Prime Cost (PC) items (allowances for specific supply items like fixtures) come into play. Your master template must establish the ground rules for how these are managed. It should dictate the process for the builder obtaining quotes, the developer's right to approve the final selection and price, and how any difference between the allowance and the actual cost is adjusted. This ensures you retain control over these variable costs and prevents them from becoming a source of budget blowouts or disputes. 

Aligning Payment Claims with the BIF Act 

Warning: It is a critical error to assume that preliminary agreements are exempt from Queensland's security of payment legislation. The payment claim and payment schedule requirements of the Building Industry Fairness (BIF) Act apply to any agreement for construction work, including early works. 

Failure to comply with the BIF Act's strict timelines can have severe consequences. If a builder issues a valid payment claim and you fail to respond with a payment schedule within the prescribed time, you may become liable for the entire amount claimed, regardless of any genuine dispute. Your PWA system must therefore incorporate these non-negotiable statutory requirements. The payment clauses in your template must align with the processes outlined in the Building Industry Fairness (Security of Payment) Act 2017, ensuring your team understands their obligations and protects your position in any potential payment dispute. 

Navigating the Critical QBCC and Legislative Landscape 

In Queensland, the construction industry is heavily regulated by the QBCC. A developer's PWA system must be built on a foundation of QBCC compliance. Ignoring the QBCC Act and associated legislation is not an option and can lead to void contracts, fines, and significant project delays. From verifying a builder licence to understanding how a building contract is defined, your system must navigate this landscape with precision. 

Does Your Preliminary Agreement Constitute a "Building Contract"? 

A key legal question is whether your PWA constitutes a "building contract" under the Queensland Building and Construction Commission Act 1991. If the scope includes "carrying out building work," it likely does. This has significant implications. Firstly, the builder must hold the appropriate class of QBCC licence for the value and nature of the work described. Secondly, if the project involves the construction of three storeys or less and has a residential component, it could trigger the need for home warranty insurance, even at this early stage. Your PWA system must be designed with legal advice to either operate clearly as a preliminary services agreement (for non-building work) or to fully comply with all requirements of a regulated building contract. 

Verifying Builder Licensing Before a Dollar is Spent 

• Illustrative Scenario: A Brisbane developer, eager to start a multi-unit residential project, engages a builder they've heard good things about. Based on a detailed letter of intent and a handshake, they pay a significant deposit for the builder to commence site clearing and detailed design coordination. Six weeks in, a consultant flags a concern. The developer's project manager finally performs a QBCC licence check and discovers the builder is only licensed for low-rise work, not the medium-rise project planned. The developer immediately realises their investment is at risk, the work performed may be uninsured and unlawful, and the project is completely stalled. The lesson is brutal and expensive: licence verification is a non-negotiable first step in any engagement system. 

Understanding QCAT's Role in Early-Stage Disputes 

Should a dispute arise from your PWA, the forum for resolution is critical. For many building disputes in Queensland, the first port of call is the Queensland Civil and Administrative Tribunal (QCAT). It's important to understand QCAT's jurisdiction. For commercial building disputes, QCAT can generally hear matters up to a value of $50,000, unless both parties agree to its jurisdiction for a higher amount. For larger-scale commercial projects, this limit may be insufficient. Therefore, a well-drafted PWA template for a major developer should include a dispute resolution clause that provides for more suitable methods, such as expert determination, arbitration, or litigation in the District or Supreme Courts, ensuring any significant conflict is handled in the appropriate forum. 

From Template to Execution: Implementing Your PWA System 

A perfectly drafted PWA template is useless if it sits on a server. The real value is unlocked through disciplined implementation. This means transforming your template from a legal document into a core part of your project management and contract administration workflow. A true developer playbook requires a system for execution, including rigorous due diligence, team training, and knowing when to seek expert legal review. 

The Importance of a Pre-Engagement Checklist 

Before your PWA is even presented to a builder, a mandatory pre-engagement checklist must be completed. This simple but critical tool acts as a gatekeeper, preventing you from entering into an agreement with an unsuitable contractor. The checklist should be a non-negotiable step in your process and include, at a minimum: 

• QBCC Licence Check: Verifying the builder's licence is current, active, and of the appropriate class for the anticipated project value and type. 

• Financial Capacity Check: A review of the builder's financial health, which could involve checking their QBCC licence record for any conditions or seeking financial statements for larger projects. 

• Insurance Verification: Sighting current Certificates of Currency for Public Liability and any other required insurances. 

• Referee Checks: Speaking with previous clients or developers about their experience with the builder. 

This checklist ensures that your robust PWA template is only used with contractors who have been properly vetted. 

Training Your Team for Consistent Application 

A system is only as good as the people who use it. Your project managers, contract administrators, and development managers must be trained on the PWA system. This isn't just about giving them a template; it's about ensuring they understand the commercial and legal reasoning behind each clause.

Training should cover the process for completing the project-specific annexures, the strict procedure for approving any variations to the preliminary scope, and, most importantly, the red flags that require immediate escalation for legal review. Consistent application across your team is what turns a good document into a powerful risk management system. 

When to Seek Legal Review for Project-Specific Variations 

While your scalable system is designed to standardise 80-90% of your preliminary engagements, it's crucial to recognise when a project's unique risks demand specific legal oversight. The standard template may not adequately cover the complexities introduced by factors like significant environmental contamination, strict heritage overlays, unconventional financing structures, or joint venture agreements.

A key part of a robust system is building in a trigger for expert review. When these high-risk factors are present, the most prudent and commercially sensible step is to engage a specialist construction lawyer to tailor the agreement. This ensures your specific risks are addressed, reflecting Merlo Law's approach of providing targeted advice where it matters most. 

When Preliminary Discussions Break Down 

Even with the best system, not all preliminary engagements will proceed to a full construction contract. A key strength of a scalable PWA system is that it anticipates this possibility and provides a clear, commercial off-ramp. When discussions break down, the focus shifts to executing a clean contract termination, managing any potential payment dispute, and avoiding costly litigation. 

Leveraging Your PWA's Exit Strategy 

When it becomes clear that a full building contract won't be agreed upon, the first step is to activate the termination clause within your PWA. The procedural narrative is straightforward: you issue a formal notice of termination as prescribed by the agreement. The next step is to calculate the final payment owed for the work validly completed, a process that should be clearly dictated by the agreement's terms on compensation and auditing. This structured exit prevents the breakup from descending into a protracted and expensive negotiation over who owes what, allowing both parties to part ways cleanly and commercially. 

What Happens if a Builder Initiates a Payment Dispute? 

If a builder believes they are owed more than you have calculated, they may initiate a payment dispute under the BIF Act. This typically involves them issuing a formal payment claim. Your best defence is your own disciplined process. By having meticulously followed the PWA's terms, kept clear records of all instructions and costs, and issued timely payment schedules in response to every claim, you will be in the strongest possible position. If the matter proceeds to adjudication, your clear, contemporaneous documentation will be the evidence that supports your position and refutes unsubstantiated claims from the builder. 

Making the Final Call: Negotiation vs. Formal Action 

Formal legal action, whether through QCAT or the courts, should always be a last resort. The associated costs, delays, and management distraction can be significant. The primary goal of your PWA system is to prevent disputes from escalating to this point. The clear documentation and agreed-upon terms put you in a powerful position to achieve a favourable negotiated settlement. However, you must also be prepared to enforce your rights. If a builder acts unreasonably or makes a claim without merit, your well-documented process provides the solid foundation needed to confidently proceed with formal dispute resolution and protect your commercial interests. 

Conclusion: From Reactive Contracts to a Proactive Development Engine 

For Queensland developers managing a pipeline of projects, the shift from drafting one-off preliminary agreements to implementing a scalable system is not just an efficiency gain; it's a strategic imperative. A robust PWA system transforms the risky, uncertain start of a project into a predictable, controlled, and repeatable process. 

By front-loading risk management, standardising legal protections, and embedding compliance with the QBCC and BIF Acts into your workflow, you gain unparalleled control. You reduce negotiation friction, protect your intellectual property, and create clear exit strategies. This system becomes a core component of your development engine, empowering you to engage builders with confidence, mobilise projects faster, and ultimately, build a more resilient and profitable development business.

FAQs

What's the biggest mistake developers make with preliminary agreements?

The most common mistake is ambiguity. Using vague terms in a simple letter of intent or heads of agreement regarding the scope of work, payment terms, and intellectual property ownership creates a breeding ground for disputes. A scalable system replaces ambiguity with absolute clarity.

Can I use a simple Letter of Intent instead of a PWA?

Letters of Intent (LOIs) are particularly risky instruments in the Queensland building context and should be approached with extreme caution. While an LOI may appear to be a simple way to signal intent and get preliminary work moving, it carries significant legal and commercial dangers. If an LOI involves payments for any form of "building work," it can inadvertently be deemed a building contract under the QBCC Act, immediately subjecting you to all statutory obligations—including the requirement that the builder hold appropriate licensing, comply with the minimum contract requirements, and provide statutory warranties—without any of the contractual protections or risk allocation mechanisms of a proper agreement. This exposes developers to disputes over scope, payment obligations, defects liability, and termination rights, often with little recourse. LOIs also frequently create ambiguity about whether the parties are bound, what work is actually authorized, and how disputes will be resolved. Developers should avoid using LOIs for any work involving payments or substantive obligations without obtaining specific legal advice. A properly drafted Preliminary Works Agreement is always the safer, more professional, and more defensible choice.

How often should I get my master PWA template reviewed by a lawyer?

It's wise to have your master template reviewed by a construction lawyer annually or whenever there are significant changes to Queensland legislation, such as amendments to the QBCC Act or the Building Industry Fairness (BIF) Act. This ensures your system remains compliant and continues to provide maximum protection.

Does the BIF Act apply to consultant agreements as well as builder agreements?

Yes. The BIF Act's definition of "construction work" is broad and can include related services like architectural design, engineering, and surveying. Therefore, the strict rules for payment claims and schedules also apply to your agreements with consultants, not just builders.

What happens if I accidentally engage an unlicensed contractor for preliminary works?

Engaging an unlicensed contractor for work that requires a QBCC licence is a serious offence under the QBCC Act. The contract may be deemed unenforceable by the contractor, you may be unable to recover payments if the work is defective, and you could face penalties from the QBCC. This is why a mandatory licence check is a critical first step in any PWA system.
