BuildCrux: Contractor Manager

BuildCrux is AI construction estimating software for remodelers and small general contractors. Drop a PDF drawing set in — residential remodels, restaurants, dental fit-outs, retail buildouts, medspa, clinics, or pharma compounding centers — and walk out with priced line items inside the dollar range a senior commercial estimator would quote, in twelve minutes.

THE WEDGE — AI ESTIMATING THAT ACTUALLY WORKS

• Multi-pass pipeline on PDF drawing sets up to 500 pages
• Residential + commercial TI: restaurants, dental, retail, medspa, clinics, pharmacies
• Sub-bid scope filter — estimate only the kitchen, only the millwork, only the MEP (built for trade contractors bidding into a GC)
• Validated against senior-estimator dollar precision: $686K on an 80-page pharma compounding center vs the $700K–$850K human-estimator reference range, with 48 line items
• Non-drawing pages (energy reports, specs) auto-filtered out of takeoff
• Cover-sheet auto-extracts address for project naming
