• A. Owner
• B. Architect
• C. Design-builder
• D. Contractor

Answer: (C)

In Phase 1, Preliminary Services, the team works with the owner to establish or confirm the project’s basis of design (BOD). The design-builder takes that BOD and drives the design forward, integrating performance requirements with design development, system selection, and constructability considerations. This leadership reflects the design-build model, where the design-builder contracts for both design and construction and coordinates the work to meet the owner’s goals, budget, and schedule. The owner provides input and approves key decisions, while the design-builder—and the design-build team it deploys, which may include architects or engineers—advances the design toward more detailed development and construction-ready documents.
