About

Piper is the AI operating system for preconstruction, built for general contractors' pursuit and estimating teams. Piper connects drawings, specifications, addenda, quotes, estimates and company knowledge so teams can generate scopes, level bids and review risk — with every finding linked back to the drawing, spec clause or addendum it came from. Scope Generation: turn drawings, specifications, addenda and company standards into source-backed trade scopes, so you know exactly what you are asking each trade to carry. Bid Leveling: compare subcontractor bids against the intended scope, so the low number does not hide an expensive gap. Final Bid Review: review the estimate against the project behind it, and focus senior attention on what still deserves judgment. Survey: turn your company's experience into a repeatable survey that captures what the team learns on every project. Piper is not a takeoff or estimating calculator, and it does not replace estimator judgment.

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.
