In DBB, the contractor's input is absent during the design process.

• A. Present
• B. Optional
• C. Partial
• D. Absent

Answer: (D)

In a design-bid-build (DBB) project, the design is developed by the design professionals under the owner's contract, independently of the contractor. The contractor is brought in only after the design is complete, during bidding and construction. Because the design phase is owned by the design team and the contractor isn’t party to the design process, the contractor’s input during design is absent. This separation helps preserve design integrity, maintain competitive bidding, and prevent early cost or constructability concerns from shaping the design. If the contractor were involved during design, that would align more with design-build or early contractor involvement, not pure DBB.
