IMC Mechanical Compliance Review

What IMC Covers for Mechanical Review

the International Mechanical Code sets the rules for design and installation requirements for HVAC, ventilation, and mechanical systems. On the mechanical side, review tends to concentrate on HVAC equipment sizing, ventilation rates, ductwork routing, and mechanical to structural coordination. Those are the areas mechanical engineers and MEP coordinators get held accountable for, and where a missed detail usually turns into a plan check comment.

Structured AI checks mechanical drawings against IMC provisions before submittal, using the same QA/QC Compliance Checks that run across every discipline. Each finding points to the exact page and location, and spells out what's wrong and how to fix it, so a reviewer can confirm it in seconds instead of hunting for it.

Checks Structured AI Runs for Mechanical Review

Structured AI's check library includes named, specific checks relevant to mechanical review, drawn from the same library used across every project regardless of which code applies. A sample of checks commonly relevant to mechanical drawing sets:

• MECH-3: Pipe Run Check
• MECH-1: Equipment Tag Check
• MECH-2: Equipment Details Check
• MAC-6: Utility and Service Coordination

These checks run alongside IMC-specific provisions covering HVAC equipment sizing, ventilation rates, ductwork routing, and mechanical to structural coordination. The check library grows as firms define additional standards worth enforcing on top of baseline code compliance.

How Structured AI Reviews IMC Mechanical Compliance

For mechanical sets in .pdf, .dwg, .rvt, or .ifc, Structured AI runs IMC checks focused on HVAC equipment sizing, ventilation rates, ductwork routing, and mechanical to structural coordination, with each finding tied to an exact sheet and location so it's easy to verify. Firms that want more than the baseline IMC coverage can write Custom Checks in plain English on top of it.

If the project lives in Revit, the Revit Add-In runs these mechanical checks straight against the live model, no export required, and reports back definite fails plus items worth double checking by element ID.

FAQ

Does Structured AI replace a licensed mechanical engineer's code review? No. This is a pre check step, built to catch likely IMC issues early. It doesn't replace sign off from a licensed professional or the jurisdiction's plan review process, it just gives both a shorter list to start from.

Which projects use IMC mechanical review? Projects in jurisdictions that have adopted IMC, where mechanical engineers and MEP coordinators need to confirm HVAC equipment sizing compliance before permit submittal or during design development.

How is this different from a general IMC check across all disciplines? This page is scoped to mechanical provisions specifically. Structured AI's check library covers every discipline and every code a firm works with, so the same deterministic, source-linked review runs across a full drawing set rather than one discipline at a time.
