Which contract type is aligned with the Design-Bid-Build delivery method?

The Design-Bid-Build (DBB) delivery method is traditionally associated with a stipulated price contract, which outlines a single agreed-upon price for the completion of the project based on designed specifications. This contract type is advantageous for owners seeking clarity regarding project costs and timelines, as the contractor bids on the work based on the complete design documents provided before construction begins.

In the context of the Design-Bid-Build method, the contractor typically takes on the responsibility for executing the work based on the detailed design prepared by the architect or design team. Under a stipulated price contract, bidding occurs once the design is finalized, allowing the project owner to choose from competitive bids, thus establishing a fixed price for the construction phase that is non-negotiable unless significant scope changes occur.

Other contract types mentioned are suited for different methods of project delivery. A construction management contract for services focuses on collaboration during the design phase and may not align with the traditional DBB approach. The design-build contract integrates design and construction services into a single contract, which deviates from the separate phases characterized by DBB. A cost-plus contract involves reimbursement of actual costs incurred plus a fee, differing fundamentally from the fixed-price nature of a stipulated price contract and typically used in scenarios where project
