Catch errors before construction
Cross-reference drainage fixture units (DFUs) against pipe sizing and code requirements. Find riser diagram inconsistencies, fixture schedule mismatches, and piping capacity issues. Results in days, not weeks.

Best for: Plumbing engineers, MEP coordinators, GCs, Plan reviewers.
Plumbing drawings define water supply, waste, and vent systems. DFU calculations must match pipe sizing, and code requirements vary by jurisdiction.
Plumbing coordination issues are especially costly because they often require field rerouting that affects multiple trades. Undersized condensate lines cause flooding and equipment damage.
Common issues that lead to costly rework:
AI reviews plumbing drawings to identify issues that manual review might miss—from DFU calculations to condensate line sizing.
In-depth guide
Sanitary drainage with DFUs, domestic risers, condensate routing, fixture schedules, and pipe sizing annotations—coordination and compliance before permit.
Fixture schedule totals that do not match riser sizing callouts—or IPC vs UPC table mismatches—create latent undersizing.
Branch demands exceeding listed main capacity appear only at pressure or inspection testing.
Combined peak condensate from multiple AHUs in undersized tubing—coordinate with mechanical review.
Fixture loads are reconciled with IPC/UPC tables, riser continuity verified, and schedules compared to plan graphics.
Drainage fixture units weight fixture load for pipe sizing per plumbing code—InspectMind compares schedule sums to riser annotations.
Risers, schedules, routing plans, and storm/specialty systems in scope.
Yes—when mechanical context is included in the upload package.
Actual issues found on real projects. Each one would have caused significant rework, change orders, or schedule delays.
What AI Found: Five AHUs connected to single 3/4" condensate line. Code and best practice recommend minimum 1" line for this capacity.
Impact: Prevented condensate backup and potential equipment damage. Would have caused flooding during peak cooling.
What AI Found: Waste line sized for 48 DFUs but fixture schedule totals 67 DFUs on connected branch.
Impact: Caught undersized drain before installation. Would have caused slow drainage and potential backups.
What AI Found: Third floor riser shows 4" waste stack but second floor shows 3" continuing down. Missing transition.
Impact: Prevented field confusion and potential code violation. RFI would have delayed rough-in.

GCs, architects, engineers, contractors, and developers use InspectMind AI to catch issues before they hit the field.
"InspectMind caught 47 critical issues on our cold storage project: conflicts that would have cost us millions in field rework. It paid for itself on the first review."
Aaron Bass
Director of Construction, Cold Summit Development
"We used to spend 40+ hours on plan review. Now I upload the drawings, and get back a complete issue report that catches code violations I would have missed. It's a no-brainer."
