Pre-Construction Plan Review: When to Run AI at 30%, 60%, 90%

6 min read

Quick Summary

  • Run AI plan check at 30%, 60%, 90%, and permit set—not just once before submittal
  • Real example: event center in Texas ran 4–5 checks over the project for continuous quality control
  • Catch issues when fixes cost hundreds, not tens of thousands—earlier catches are cheaper
  • Same-day results; volume commitment sheet cap covers multiple checks across projects

Pre-construction plan review isn't a one-and-done step. The best outcomes come from running AI plan check at multiple milestones—30% design development, 60% construction documents, 90%, and the permit set—so you catch issues when they're cheap to fix and avoid compounding problems.

Why Run at 30%, 60%, 90% and Permit Set?

Design evolves. What looked fine at 30% can create coordination conflicts by 60%. By 90%, missing details and spec vs drawing mismatches show up. If you only check once (e.g. right before permit), you're fixing everything at the most expensive moment—and you may still miss issues the city or contractor will find later.

Cost of Late Catches

  • Issues caught at 30% cost 1× to fix; at 90% or in the field they cost 10–100× more
  • City comments and RFIs are reduced when you've already fixed most issues before submittal

Real Example: Event Center, Texas

A small-town event center used AI plan check at multiple stages. The first check was at the 30% set (around December/January); the latest was the 100% set. In between, they ran checks at 60% and 90%. Each run found issues—coordination, code, spec vs drawing—that they fixed before the next milestone. The result: continuous quality control without waiting for the city or the contractor to find problems.

30% — Early DD

Major coordination and feasibility. Catch layout and system conflicts before they're baked in.

60% / 90% — CD

Full code compliance, cross-discipline alignment, spec vs drawing, and completeness.

How It Works

Upload your PDFs at each milestone—drawings, specs, and any internal standards. Confirm the building codes the AI will check, run the check, and get results in hours (same day for typical sets). Filter by discipline and severity, assign issues to your team, export to Excel, or one-click RFI. With a volume commitment, your monthly sheet cap covers all projects and re-checks, so running 30%, 60%, 90%, and permit set doesn't require per-check upsells.

Progress set review → and plan check at 30%, 60%, 90% and permit set cover the same workflow in more detail. To try it on your next project, get started —upload a set and run a check; most teams see value after one run.
