Who is identified as the person or team responsible for the bridge design?

• A. Responsible Engineer
• B. Project Manager
• C. Construction Supervisor
• D. Design Engineer

Answer: (A)

The main idea is that someone is formally accountable for the bridge design. In this context, the Responsible Engineer is the person or team designated to take legal and professional responsibility for the design, verify that it meets all codes and standards, and sign off on the design documents. This designation explicitly signals accountability for the structural adequacy and safety of the design, which is the core duty in design phases.

A Design Engineer performs the technical design work, but the Responsible Engineer is the individual or team authorized to assume liability and provide the professional seal or approval. The Project Manager oversees scope, schedule, and coordination, while the Construction Supervisor handles on-site construction supervision.
