During construction, you discover that the structural steel fabricator's shop drawings show a connection detail that differs from the original structural drawings. What is the appropriate next step?
Correct Answer
A) Stop work and contact the structural engineer
Any discrepancies between shop drawings and original structural drawings must be resolved by the structural engineer before proceeding. This ensures structural integrity and design compliance.
Why This Is the Correct Answer
When discrepancies exist between shop drawings and original structural drawings, the structural engineer must resolve the conflict before any work proceeds. The engineer of record is responsible for ensuring structural integrity and must approve any deviations from the original design. Proceeding without engineer approval could compromise structural safety and violate building codes. This protects both the contractor and building occupants from potential structural failures.
Why the Other Options Are Wrong
Option C: Use the original structural drawings instead
Proceeding with fabrication based solely on shop drawings when there's a discrepancy with original drawings is dangerous and potentially illegal. Shop drawings are prepared by fabricators and must be reviewed and approved by the engineer of record before implementation.
Option D: Proceed with fabrication as shown on shop drawings
Simply using the original structural drawings without resolving the discrepancy ignores the fact that shop drawings may contain valid field conditions or fabrication constraints that need engineering consideration. The conflict must be formally resolved.

Think 'STOP and CALL' - Stop work immediately and Call the structural engineer for any structural discrepancies
