07 84 00 Firestopping: Common Contradictions and RFI Guide
Fire rating requirements between architectural drawings and spec section 07 84 00 are the single most common contradiction type Lintel surfaces across all project types.
Most Firestopping contradictions trace to the same root: the specification and the drawings are produced by different people at different stages, and never fully reconciled before the set goes out. By the time the conflict is found in the field, it is an RFI, a delay, or a change order.
Lintel cross-references section 07 84 00 against your full drawing set, schedules, and the rest of the project manual, flagging every disagreement with a citation to the exact page so it is resolved in review.
Common contradiction types
Fire rating on A-sheets vs. spec assembly
A frequent firestopping conflict. Lintel reconciles the drawings against the spec to surface it with a page-level citation, so it is caught in review rather than at rough-in.
Penetration seal detail conflicts
A frequent firestopping conflict. Lintel reconciles the drawings against the spec to surface it with a page-level citation, so it is caught in review rather than at rough-in.
UL assembly number mismatch
A frequent firestopping conflict. Lintel reconciles the drawings against the spec to surface it with a page-level citation, so it is caught in review rather than at rough-in.
Frequent RFIs
- Fire rating mismatch at rated wall penetrations
- Firestopping product not matching UL listing
- Missing penetration details on architectural plans
