About
PreConstruct AI is a web-based construction takeoff and estimating application for subcontractors bidding interior finishes, concrete, and wood framing work from PDF drawing sets. It reads drawing scales and uses plan notes, schedules, and partition legends to help identify and measure walls, ceilings, and concrete quantities. AI-assisted wall suggestions are in beta and are reviewed, approved, or adjusted by the estimator. Approved quantities become material lists for items such as studs, board, insulation, tape, compound, paint, concrete, and rebar, with calculations and drawing-sheet references. Estimators can apply their own material prices, create proposal PDFs, and export data to Excel or CSV. Projects can use imperial units, metric units, or both. The application supports estimating workflows; estimators review measurements and quantities before submitting a bid.
