In a Design-Build project, which description is accurate about the consultant's responsibilities?

• A. The consultant holds primary design responsibility.
• B. The consultant manages day-to-day construction on site.
• C. The consultant acts as a project manager for cost control.
• D. The consultant acts as an adviser or reviewer but does not hold design responsibility.

Answer: (D)

In a design-build setup, the design and construction responsibilities are consolidated under the design-builder, who takes on the primary design responsibility. The consultant’s role is to act as an adviser or reviewer, providing expert input, ensuring that the design meets requirements, codes, and constructability needs, and helping with quality control. They don’t carry the ultimate design liability or authority for the project’s design decisions. That accountability remains with the design-builder and the contractual team, while the consultant supports the process with review and technical guidance.

The other options describe activities more typical of the design-builder’s own team or a separate on-site manager (day-to-day construction, cost-management leadership, etc.), which aren’t the standard role of the consultant in a design-build arrangement.
