Shop Drawing Review for Subcontractors

Why Subcontractors Need Shop Drawing Review

Subcontractors are accountable for their trade's shop drawings and making sure installation matches design intent and adjacent trades. One thing that keeps coming up for this role is shop drawings getting rejected or reworked because of conflicts with other trades that weren't visible at bid time.

Shop Drawing Review addresses this head on, applied when subcontractor or fabricator shop drawings need to be checked against design intent and adjacent trades. The goal is straightforward: cut down shop drawing rejection cycles and catch trade conflicts before fabrication starts.

What Structured AI Checks for Subcontractors

For subcontractors running shop drawing review, Structured AI uses Comment Closure, which reviews every markup against submittal drawings and returns an evidence backed verdict, plus Overlay to catch trade conflicts before fabrication. Findings are scoped to what this role is actually on the hook for, not a generic error list, but issues organized around their trade's shop drawings and making sure installation matches design intent and adjacent trades.

Comment Closure reviews every markup against submittal drawings and returns an evidence-backed verdict, which cuts down the back-and-forth on shop drawing rejections tied to conflicts with other trades that weren't visible when the drawing was first prepared.

Where This Fits in Your Workflow

Shop Drawing Review for subcontractors usually happens when subcontractor or fabricator shop drawings need to be checked against design intent and adjacent trades. Structured AI works on .pdf, .dwg, .rvt, and .ifc files, and for Revit modeled projects, the Revit Add-In runs the same checks directly against live geometry with element level results, no export needed. Findings can be exported and assigned by trade or discipline, so the review step slots into the existing document workflow instead of adding a new one.

FAQ

How is shop drawing review different from a general plan check? Shop Drawing Review is scoped to what actually matters at this stage of the project and for this role: cut down shop drawing rejection cycles and catch trade conflicts before fabrication starts. It uses Structured AI's deterministic checks rather than a confidence-scored, probabilistic flag.

Do subcontractors need special training to use this? No. Upload the relevant drawings and specifications, or connect the Revit model directly, and findings come back organized the way subcontractors already review work. Teams can also build Custom Checks in plain English without writing any code.

Can findings be shared with the rest of the project team? Yes. Every finding links back to the exact sheet and location, and can be exported and assigned by trade or discipline for team wide visibility and follow up.
