Concrete Mix AI turns a plan set into quantities: concrete by element, rebar, block and grout counts, each traced to the drawing, plus the questions for your engineer. Free concrete takeoff from your PDF or DWG, no account. It also has 12 free concrete calculators, including mix design based on ACI 211 principles, compressive strength, water-cement ratio, volume, rebar and curing time, plus free ACI practice exams.

Upload a vector PDF or DWG of the full plan set, with the drawings, the general notes and the specs. Add your email and click the link we send you; the takeoff starts after that click. Every sheet is read: schedules, legends, notes and dimensions. The scale is checked against the drawing's own dimensions, and each item is measured the way the plans and specs say it is paid. When the schedule, the drawings and the specs disagree, the conflict comes back as a question for your engineer instead of a guess.
You get a private link to your takeoff and a quantities CSV by email. The link shows your plan with every counted item colored, the numbers in plain words, "How we got this" for each item, and a 3D build-up and build sequence of the job. A material cost estimate from typical delivered prices for the job's region is included. It is an estimate, not a bid: verify before ordering.
Concrete Mix AI also has 12 free concrete calculators, including mix design based on ACI 211 principles, compressive strength, water-cement ratio, volume, rebar, curing time and pavement thickness, plus free ACI certification practice exams in English and Spanish. Treat every calculator result as a starting point and verify with trial batches, testing and your project's code.

Groundbook AI provides quantity takeoffs and construction plan review for architects, engineers, contractors, and owners. Takeoffs include quantities and counts marked on the drawings for verification. It reviews PDF and DWG drawings against specifications, checklists, and building codes to find conflicts and missing information before construction. Each finding includes severity, impact, a recommended fix, and exact source links. Smart Overlay aligns drawings for comparison. The first eligible project is free, with pay-as-you-go pricing afterward.
