In Design-Bid-Build, what must be finished before construction begins?

• A. The Procurement of Materials
• B. The Site Survey
• C. The Design Phase
• D. The Construction Scheduling

Answer: (C)

In Design-Bid-Build, construction can begin only after the design work is finished and construction documents are issued. The design phase produces drawings and specifications that define the project scope, materials, and methods. Contractors bid based on those complete documents, and the chosen contractor builds to them. Without a finalized design, bids are unreliable, scopes are unclear, and change orders during construction would erode cost and schedule control. Permits and approvals are also sought against those finalized documents, so they must be in place before breaking ground. While site surveys, procurement planning, and scheduling are important, they do not by themselves unlock construction—the process hinges on having a complete design and corresponding construction documents.
