09 21 16 Gypsum Board Assemblies: Common Contradictions and RFI Guide
Partition type conflicts between architectural plans and the gypsum board spec are pervasive on commercial projects and drive high RFI volume.
Most Gypsum Board Assemblies 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 09 21 16 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
Partition type on plan vs. spec assembly
A frequent gypsum board assemblies 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.
STC rating conflicts
A frequent gypsum board assemblies 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.
Fire rating vs. partition schedule
A frequent gypsum board assemblies 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
- Wall type callout not in partition schedule
- STC rating mismatch at tenant demising walls
