Vertical AI for construction: blueprint agent
Construction PMs spend half their day on takeoffs, RFIs, and submittal review. The AI that does all three from a PDF blueprint wins the small-and-mid-market GC.
Why now
PDF parsing and computer-vision matured to the point where reading a blueprint is a solved problem. Procore and PlanGrid sell to the top 200 GCs. The 50,000 mid-market GCs run on Bluebeam + Excel.
The idea you could build today
Upload a blueprint set. Agent extracts a quantity takeoff, lists discrepancies, drafts RFIs against ambiguous spec callouts. Bill per blueprint set processed.
Build stack
- ·PDF + OCR (Unstructured / LlamaParse)
- ·Anthropic Claude for the spec reasoning
- ·Postgres for the project graph
- ·S3 for the blueprint storage

Frequently asked
What about Procore?+
Procore's $1.2B revenue is all top-200 GCs. The mid-market is where the AI-native product wins because they can't afford a Procore seat anyway.
