In a Design-Build project, which description correctly describes the consultant's role?

• A. The consultant leads design with full authority.
• B. The consultant serves as an independent estimator.
• C. The consultant handles procurement.
• D. The consultant acts as an advisor or reviewer but does not hold design responsibility.

Answer: (D)

In a Design-Build project, the design and construction responsibilities are bundled under the design-builder, while outside consultants typically provide independent checks and guidance. The consultant’s job is to act as an advisor or reviewer, verifying that designs, materials, and details meet codes, standards, and project requirements, and offering expert input—but they do not carry the authority to lead or approve the design themselves. Procurement and primary design leadership fall to the design-build team or the owner’s chosen agents, not to the consultant. So describing the consultant as an advisor or reviewer without design responsibility best fits the role in this setup.
