AASHTO Mechanical Compliance Review

What AASHTO Covers for Mechanical Review

the AASHTO design standards governs design standards for bridges, highways, and transportation infrastructure, mostly relevant to civil and structural review on public works projects. 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.

Structured AI's QA/QC Compliance Checks run mechanical 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 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
• MECH-5: Volume Damper BIM Check
• MECH-1: Equipment Tag Check
• MECH-3: Pipe Run Check

These checks run alongside AASHTO-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 AASHTO Mechanical Compliance

For mechanical sets in .pdf, .dwg, .rvt, or .ifc, Structured AI runs AASHTO 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 AASHTO 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. These are pre submittal checks meant to surface likely AASHTO 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 AASHTO mechanical review? Projects in jurisdictions that have adopted AASHTO, 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 AASHTO 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.
