During plan review, a contractor notices that the fire-rated wall assembly specified in Division 09 conflicts with the fire rating shown on the architectural floor plan. The specification calls for a 2-hour rating while the floor plan shows 1-hour. What action should be taken?
Correct Answer
A) Submit an RFI to resolve the conflict before proceeding
Any conflict between drawings and specifications must be resolved through proper channels (RFI) before construction proceeds. Fire ratings are critical safety issues that require accurate resolution.
Why This Is the Correct Answer
When there are conflicts between contract documents (drawings vs. specifications), the contractor must never assume which document takes precedence or make independent decisions about critical safety systems. Fire ratings are life safety issues that must be precisely correct according to code requirements. An RFI (Request for Information) is the proper contractual procedure to get clarification from the design team before proceeding with construction. This protects the contractor from liability and ensures the building meets all safety requirements.
Why the Other Options Are Wrong
Option B: Use whichever rating is less expensive to construct
While specifications often take precedence over drawings in many contracts, this is not universal and should never be assumed. Fire rating conflicts require definitive clarification, not assumptions about document hierarchy.
Option C: Use the 2-hour rating since specifications take precedence
Assuming the floor plan is more current is dangerous speculation without verification. Contract documents don't automatically have precedence based on perceived currency, and fire ratings are too critical for assumptions.
Option D: Use the 1-hour rating since the floor plan is more current
Cost should never be the determining factor for fire safety systems. Fire ratings are code-mandated safety requirements that must meet specific performance criteria regardless of construction cost.
Memory Technique
RFI = 'Resolve Fire Issues' - whenever you see conflicts in fire ratings, think RFI immediately
