23 05 00 Common Work Results for HVAC: Common Contradictions and RFI Guide
Division 23 common requirements for hangers, supports, and vibration isolation conflict with structural drawings on allowable loads and attachment methods.
Most Common Work Results for HVAC 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 23 05 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
Hanger load vs. structural capacity
A frequent common work results for hvac 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.
Vibration isolation spec conflicts
A frequent common work results for hvac 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.
Seismic bracing requirement gaps
A frequent common work results for hvac 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
- Hanger load not meeting structural capacity
- Vibration isolation type conflict between spec and equipment schedule
- Seismic bracing requirement not on structural drawings
