A contractor receives shop drawings that show a structural beam connection detail that differs from the original structural drawings. The shop drawings are stamped by a licensed engineer. What should the contractor do?
Correct Answer
C) Submit both drawings to the architect/engineer of record for review
Even though shop drawings are engineer-stamped, any conflicts with the original design must be resolved by the architect/engineer of record. The contractor should submit both for review and clarification.
Why This Is the Correct Answer
When there are conflicts between shop drawings and original structural drawings, the contractor must submit both to the architect/engineer of record for review and clarification. Even though shop drawings may be stamped by a licensed engineer, they are prepared by fabricators or subcontractors and must be reviewed against the original design intent. The architect/engineer of record has the authority and responsibility to resolve conflicts and ensure the design integrity is maintained. This protects all parties and ensures proper documentation of any changes.
Why the Other Options Are Wrong
Option A: Proceed with the shop drawing details since they are engineer-stamped
While shop drawings may be engineer-stamped, this doesn't automatically override the original structural drawings. The stamping engineer may not have full knowledge of the overall design intent, and conflicts must be resolved through proper channels.
Option B: Follow the original structural drawings regardless of the shop drawings
Simply following the original drawings without addressing the conflict ignores potentially valid engineering improvements or necessary modifications shown in the shop drawings. This could lead to construction problems or missed opportunities for better solutions.
Option D: Split the difference between the two details
Splitting the difference between two engineering details is never appropriate and could create a structurally unsafe or non-compliant condition. Engineering details must be precise and cannot be arbitrarily modified.
