This article, prepared by our building and construction law team, outlines the key contract terms for pool construction projects, addresses common pitfalls, and answers frequently asked questions to help you avoid legal issues and costly delays.
Key Takeaways
- Pool construction contracts should clearly define the scope of works, contract sum, and all parties’ obligations
- The Australian Standard AS 4902-2000 is commonly used for design and construct pool projects

- Legislative compliance is mandatory, including building codes and work health and safety laws
- Dispute resolution mechanisms must be clearly set out to manage potential conflicts
Structure of a Pool Construction Contract
What Should Be in a Pool Construction Contract?
A typical pool construction agreement in Australia will include:
- Formal Instrument of Agreement: Sets out the core terms and parties’ signatures
- Annexures: Project-specific data (e.g., key dates, insurance levels, personnel)
- General Conditions of Contract: Often based on AS 4902-2000 for design and construct projects
- Project Requirements: Technical specifications, drawings, and reports
- Special Conditions: Amendments or additions tailored to the specific project
Resolving Conflicts Between Contract Documents
To avoid disputes, state an order of precedence (which document takes priority if there’s a contradiction):
- Formal Instrument of Agreement
- Special Conditions
- Amended General Conditions
- Annexures
- Project Requirements
Key Clauses in Pool Construction Contracts
Lump Sum (Fixed Pricing) and Provisional Sums
- Lump Sum: The contractor agrees to complete the works for a fixed price, not subject to rise and fall unless specified
- Provisional Sums: Allowances for uncertain items (e.g., unforeseen ground conditions), with profit and attendance percentages applied as agreed
Insurance and Security
Your contract should specify:
- Contract Works Insurance: Contractor provides insurance covering the project, including public liability (commonly $20 million per occurrence)
- Professional Indemnity Insurance: Minimum cover (typically $5 million), maintained for several years post-completion
- Security: Usually provided by bank guarantees up to 5% of the contract sum
Legislative Compliance with Construction Law in Australia
Contracts must require compliance with all relevant legislation, including:
- Building Code of Australia
- Work Health & Safety Act 2011 (state-specific, e.g., Qld)
- Modern Slavery Act 2018 (Cth)
Risk Allocation and Limitation of Liability
A well-drafted pool builder contract should:
- Cap total liability: Often limited to 100% of the contract sum or available insurance.
- Exclude certain losses: Consequential losses (e.g., profit loss) are usually excluded or capped at 3% of the contract sum.
- Protect against non-excludable risks: Personal injury, fraud, and statutory breaches cannot be excluded by law.

Variations and Claims
- Variations must be documented (preferably in writing) and priced per agreed mechanisms
- Strict notice requirements for claims and extensions of time (EOTs)
- Delay damages and liquidated damages are typically capped to limit exposure
Dispute Resolution
Your contract should include a step-by-step dispute resolution process, such as:
Early dispute resolution meetings
Arbitration (with an agreed nominator)
Summary relief for urgent matters
Also, the Security of Payment Act applies in every Australian state and territory. This helps contractors and subcontractors get paid on time.

Special Conditions: Tailoring the Contract
Special conditions in pool construction contracts can be customised and may include:
- Specific inclusions and exclusions (e.g., filtration systems, fencing)
- Payment terms and deposit requirements
- Site management and environmental obligations
- Permits and approvals (who is responsible)
- Cost-saving proposal processes
- Modern slavery compliance requirements
Example: In a school project, special conditions might specify non-slip tiles, child-safe gates, or energy-efficient equipment.
