AASHTO Plumbing Compliance Review

What AASHTO Covers for Plumbing Review

the AASHTO design standards sets the rules for design standards for bridges, highways, and transportation infrastructure, mostly relevant to civil and structural review on public works projects. On the plumbing side, review tends to concentrate on fixture units, pipe sizing, venting, and water supply and drainage coordination. Those are the areas plumbing engineers get held accountable for, and where a missed detail usually turns into a plan check comment.

Structured AI's QA/QC Compliance Checks run plumbing drawing sets against AASHTO provisions before anything leaves the office. Every check comes back with the exact page, the exact spot on that page, what's wrong, and how to fix it. It's a list your team can act on, not a confidence score they have to argue with.

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

These checks run alongside AASHTO-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 AASHTO Plumbing Compliance

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

For AASHTO projects modeled in Revit, the Revit Add-In runs the same plumbing 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 plumbing engineer's code review? No. This is a pre check step, built to catch likely AASHTO 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 AASHTO plumbing review? Projects in jurisdictions that have adopted AASHTO, where plumbing engineers need to confirm fixture units compliance before permit submittal or during design development.

How is this different from a general AASHTO 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.
