31 20 00 Earth Moving: Common Contradictions and RFI Guide

Earthwork specs conflict with civil drawings on compaction requirements, bearing capacity, and fill material classification.

Most Earth Moving 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 31 20 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.

What goes wrong

Common contradiction types

Compaction requirement vs. civil drawing

A frequent earth moving 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.

Bearing capacity conflicts

A frequent earth moving 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.

Fill material classification gaps

A frequent earth moving 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.

In the field

Frequent RFIs

  • Compaction requirement conflict between spec and civil note
  • Bearing capacity not matching structural foundation design
  • Fill material classification not specified on civil plans
