What is a Design Build Lump Sum Contract?

The Design Build Lump Sum Contract is a specialized agreement used in the Australian construction industry where a single contractor takes responsibility for both design and construction services for a fixed price. This contract type is particularly suitable for projects where the principal wants to transfer design risk and seek cost certainty, while maintaining a single point of responsibility. It includes comprehensive provisions for design development, construction standards, payment mechanisms, and risk allocation, all aligned with Australian federal and state legislation. The document incorporates security of payment requirements, work health and safety obligations, and environmental compliance requirements specific to Australian jurisdictions. This contract type is commonly used for commercial, industrial, and infrastructure projects where the scope can be clearly defined and the contractor has the capability to manage both design and construction elements.
