Should the one-line or the panel schedules govern?

They must agree; a mismatch is itself the finding. Which is correct is the engineer’s call.

Does AI review catch 3D clashes?

It catches text and callout inconsistencies. Spatial clashes between disciplines need geometric review or BIM coordination.

MEP Plan Review Checklist

Short answer

Reviewing MEP plans means checking coordination between the mechanical, electrical, and plumbing disciplines, that panel schedules agree with the one-line diagram, that duct and pipe sizes are consistent across plans and schedules, and that equipment has the clearances it needs.

MEP review is fundamentally a coordination exercise: three disciplines drawn by three parties that must coexist in the same ceiling, shaft, and plant room. Most findings are clashes and mismatches between sheets rather than standalone errors.

The checklist below is the organised version of that pass — cross-discipline first, then each system against its own schedules.

What a review of MEP plans checks

Duct, pipe, and cable tray routing does not conflict with structure or each other.
Panel schedules agree with the one-line/riser diagram — breaker sizes, loads, feeders.
Equipment schedules match the plans — tag, capacity, electrical requirements.
Duct and pipe sizes are consistent where shown on multiple sheets.
Maintenance clearances around equipment meet code and manufacturer needs.
Plumbing fixture counts and drainage sizes match the fixture schedule.
Fire/smoke dampers shown at rated wall and shaft penetrations.
Equipment disconnects, clearances, and working space are dimensioned.

The coordination problem

The classic failure is a duct that must dive under a beam where a pipe already runs — drawn correctly on each discipline’s own sheets and wrong only in combination. Effective MEP review deliberately reads across disciplines at the congestion points: plant rooms, corridors, shafts.

Schedule cross-checks

A large share of findings is numeric: an AHU whose electrical requirements on the mechanical schedule do not match the electrical plans, a pipe size that changes between the floor plan and the riser. These are exactly the cross-references AI-assisted review flags with sheet citations — PDFDepth’s Plan Review reads the whole set and reports mismatches for a human to verify.
