Mix Chapter
Mix Chapter offers an online concrete plan takeoff service for concrete contractors, estimators and other construction professionals. Users submit plans as a vector PDF, DWG or DXF and receive a private link to the takeoff and a quantities CSV. The service estimates concrete quantities by element, reinforcing steel quantities, and concrete masonry unit block and grout counts. Results are shown on the project drawings with calculation details so users can review how quantities were derived. The workflow checks drawing scale against dimensions on the plans and supports estimating and preliminary material planning. Takeoffs are estimates, not bids, and should be reviewed against project documents before materials are ordered. Access is free, with one takeoff per email address every 24 hours and up to three per company email domain each day; no account is required.

PreConstruct AI
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.
