How is design-Bid-Build defined in project delivery methods?

Design-Bid-Build is a traditional project delivery method characterized by a clear and linear process where the design phase is completed prior to the bidding and construction phases. This method involves three distinct phases: first, the designer completes the project design, including all plans and specifications; second, the completed design is made available for contractors to prepare their bids; and finally, the selected contractor executes the construction work based on the finalized design documents.

This structured sequence allows for a comprehensive assessment of the project details before construction begins, helping to ensure that bids are based on the same design parameters and reducing the potential for misunderstandings or disputes during construction. Therefore, this method emphasizes thorough upfront planning and design, which can lead to a clearer scope and expectations for all parties involved.
