Stipulated Price Contract Template for Australia

A stipulated price contract is a fixed-price construction agreement that establishes a predetermined contract sum for the entire scope of works. Under Australian law, this contract type provides cost certainty and clear financial obligations for both parties, making it one of the most commonly used procurement methods in the construction industry.

When do you need this document?

You need a stipulated price contract when undertaking construction projects where the scope of work is well-defined and detailed specifications are available. This contract type is particularly suitable for projects with minimal expected variations, such as standard residential developments, commercial fit-outs, or infrastructure projects with established designs. It's also preferred when principals require budget certainty and want to transfer construction risk to the contractor. The fixed-price nature makes it ideal for projects funded through loans or where strict financial controls are necessary.

Key legal considerations

The contract sum clause is fundamental, clearly specifying what is included and excluded from the fixed price. You must carefully define the scope of works to prevent disputes over additional costs. Variation clauses are crucial as they establish procedures for changes to the original scope and pricing mechanisms for additional work. Risk allocation provisions determine which party bears responsibility for unforeseen conditions, delays, or cost overruns. Payment terms must comply with security of payment legislation, including progress payment schedules and claim procedures. Time provisions should include practical completion dates, liquidated damages for delays, and extension of time procedures. Quality and defects clauses establish performance standards and rectification obligations.

Legal requirements in Australia

Australian stipulated price contracts must comply with the Building and Construction Industry Security of Payment Act, which mandates specific payment claim procedures and timeframes for progress payments. The Competition and Consumer Act 2010 governs unfair contract terms, particularly in standard form contracts, ensuring terms don't create significant imbalances between parties. Work Health and Safety Act 2011 requirements must be addressed through safety obligations and compliance procedures. The National Construction Code sets minimum building standards that must be incorporated into the scope of works. State-specific building legislation may impose additional licensing, insurance, and performance requirements. Contract formation must satisfy Contract Law Act principles including offer, acceptance, and consideration. Professional indemnity and public liability insurance requirements vary by jurisdiction and project value, and these must be clearly specified in the contract terms.
