When there are questions about a structural steel plan, whom should be consulted?

• A. Architect
• B. Structural engineer
• C. Project manager
• D. Inspector

Answer: (B)

Structural questions on a steel plan should be directed to the structural engineer of record. They designed the system, so they hold the calculations, intended load paths, and specific connection details that the drawings rely on. When something in the plan is unclear or a field condition requires interpretation, the engineer provides the authoritative clarification or approves changes that affect safety and code compliance. The architect focuses on overall design intent and aesthetics, not the technical structural decisions. The project manager coordinates schedules and communication but isn’t the source for structural design guidance. Inspectors verify conformity to the plans and codes, not interpret the engineering design. If a detail looks ambiguous or seems impractical in the field, turning to the structural engineer ensures the interpretation aligns with the approved design and safety requirements.
