22 40 00 Plumbing Fixtures: Common Contradictions and RFI Guide
Fixture schedule, specification section, and plumbing plans create three-way contradictions on model, rough-in dimension, and ADA compliance.
Most Plumbing Fixtures 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 22 40 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
Fixture model vs. schedule
A frequent plumbing fixtures 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.
Rough-in dimension conflicts
A frequent plumbing fixtures 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.
ADA compliance gaps
A frequent plumbing fixtures 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
- Fixture model not matching plumbing schedule
- Rough-in dimension conflict between spec and plan
