Buyer's guide
AI that reads full PDF drawing sets for conflicts, gaps, and risk — before they become RFIs.
This is the category attacking construction's most expensive document problem: the average RFI costs around $1,080 to process, and roughly a third trace back to drawing conflicts and missing information that existed before ground broke. AI review tools cross-reference entire 2D drawing sets — no model required — and flag coordination conflicts, code issues, and scope gaps with sheet references.
They differ on audience: general contractors reviewing bid sets for risk (Firmus, Provision), design teams running QA before issue (MarkedUp, Tuuli), and both-sided platforms that push findings straight out as RFIs (Articulate). All position AI as a first pass a professional verifies.
AI trained on construction drawings cross-references every sheet to catch coordination conflicts and code issues, with one-click RFIs to Procore.
AI reads 2D drawing sets to flag scope gaps, missing information and risks before they become RFIs and change orders.

Callout uses AI to review construction drawing PDFs against 33+ building codes across 7 engineering disciplines.
InspectMind AI automatically reviews construction drawings and engineering plans against building codes and design best practices. The platform identifies errors, missing details, and compliance issues in minutes—helping engineers and architects catch problems early and avoid costly construction mistakes.
Run the math on your own numbers with our free RFI cost calculator — at the industry-average $1,080 per RFI and a preventable share around a third, mid-size GCs typically find six figures a year in addressable cost.
No — this category works on 2D PDF drawing sets, which is precisely its value: most bid sets and many CD sets are still reviewed as PDFs regardless of what was modeled.
Both benefit for different reasons: architects catch coordination issues before issue, GCs catch scope risk before bid. The strongest results come when findings feed a shared workflow instead of a blame trail.
