IBC Mechanical Compliance Review

What IBC Covers for Mechanical Review

the International Building Code governs the base building code adopted, often with local amendments, across most U.S. jurisdictions outside a few states that keep their own code, like California, Florida, and New York City. For mechanical review specifically, the parts that matter most are HVAC equipment sizing, ventilation rates, ductwork routing, and mechanical to structural coordination. That's where mechanical engineers and MEP coordinators carry the most compliance risk, and where plan check comments most often start.

Before a set goes out, Structured AI's QA/QC Compliance Checks review mechanical drawings against IBC. The output is deterministic: exact page, exact location, the issue, and the fix. No confidence percentage to second guess, just a list the team can sign off on.

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-6: Volume Damper Check
• MAC-6: Utility and Service Coordination
• MECH-1: Equipment Tag Check
• MECH-2: Equipment Details Check

These checks run alongside IBC-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 IBC Mechanical Compliance

For mechanical sets in .pdf, .dwg, .rvt, or .ifc, Structured AI runs IBC 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 IBC coverage can write Custom Checks in plain English on top of it.

For IBC projects modeled in Revit, the Revit Add-In runs the same mechanical checks directly against live geometry, flagging definite fails and items to verify by exact element ID. Nothing needs to be exported first.

FAQ

Does Structured AI replace a licensed mechanical engineer's code review? No. This is a pre check step, built to catch likely IBC 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 IBC mechanical review? Projects in jurisdictions that have adopted IBC, 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 IBC 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.
