Your subcontractor submits shop drawings for structural steel that show a connection detail different from the contract documents. What is the appropriate action?
Correct Answer
D) Forward to the structural engineer for review
Shop drawings showing deviations from contract documents must be reviewed by the appropriate design professional (structural engineer) who can evaluate the proposed changes for adequacy and code compliance.
Why This Is the Correct Answer
When shop drawings deviate from contract documents, especially for structural elements, they must be reviewed by the qualified design professional who created the original design. Only a structural engineer has the expertise to evaluate whether the proposed connection detail maintains structural integrity, meets code requirements, and is equivalent to or better than the original design. The contractor lacks the professional qualifications to make this determination independently.
Why the Other Options Are Wrong
Option A: Request a cost proposal for the change
Requesting a cost proposal assumes the change is acceptable and focuses on pricing rather than technical adequacy. The primary concern is whether the deviation is structurally sound and code-compliant, not the cost implications. Cost discussions should only occur after engineering approval.
Option B: Approve the shop drawings if they appear adequate
Contractors are not qualified to determine if structural modifications are adequate. Even if shop drawings appear reasonable, only a licensed structural engineer can verify that the proposed connection meets load requirements, safety factors, and building codes. Approving without proper review creates liability issues.
Option C: Reject the shop drawings immediately
Immediately rejecting shop drawings without proper review is premature and potentially wasteful. The proposed detail might be equivalent or superior to the original design. Professional engineering review is needed to make an informed decision about the deviation's acceptability.
Memory Technique
Remember 'STEEL = Send To Engineer for Evaluation and Liability protection' - structural steel changes always need engineer review.
