Design-bid-build (DBB) is a traditional project delivery method in construction where the project is divided into three sequential phases: design, bidding, and construction. The design team creates detailed plans and specifications, which are then used to solicit bids from contractors. The contract is awarded to the lowest responsible bidder, and construction follows based on the finalized design.
