IPC Plumbing Compliance Review

What IPC Covers for Plumbing Review

the International Plumbing Code governs design and installation requirements for plumbing systems, fixture counts, and water supply and drainage. For plumbing review specifically, the parts that matter most are fixture units, pipe sizing, venting, and water supply and drainage coordination. That's where plumbing engineers 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 plumbing drawings against IPC. 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 Plumbing Review

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

• WPF-004: Membrane Upturns and Extent Annotation
• PIPE-1: Pipe Sizing Velocity Check
• WPF-001: Wet Area Extents, Falls, and Wastes
• MECH-3: Pipe Run Check

These checks run alongside IPC-specific provisions covering fixture units, pipe sizing, venting, and water supply and drainage coordination. The check library grows as firms define additional standards worth enforcing on top of baseline code compliance.

How Structured AI Reviews IPC Plumbing Compliance

For plumbing sets in .pdf, .dwg, .rvt, or .ifc, Structured AI runs IPC checks focused on fixture units, pipe sizing, venting, and water supply and drainage coordination, with each finding tied to an exact sheet and location so it's easy to verify. Firms that want more than the baseline IPC coverage can write Custom Checks in plain English on top of it.

If the project lives in Revit, the Revit Add-In runs these plumbing 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 plumbing engineer's code review? No. These are pre submittal checks meant to surface likely IPC issues before they reach a plan reviewer or the field. They support a licensed professional's sign off and the jurisdiction's own plan review, not replace either one.

Which projects use IPC plumbing review? Projects in jurisdictions that have adopted IPC, where plumbing engineers need to confirm fixture units compliance before permit submittal or during design development.

How is this different from a general IPC check across all disciplines? This page is scoped to plumbing 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.
