03 30 00 Cast-in-Place Concrete: Common Contradictions and RFI Guide
Contradictions between concrete mix design in the spec and structural drawings are among the most costly to resolve in the field.
Most Cast-in-Place Concrete 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 03 30 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
Mix design vs. structural drawing callouts
A frequent cast-in-place concrete 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.
Reinforcement cover conflicts
A frequent cast-in-place concrete 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.
Formwork removal schedule vs. spec curing requirements
A frequent cast-in-place concrete 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
- Concrete strength specification mismatch
- Rebar spacing conflict between S-sheets and spec
- Curing duration not matching structural requirements
