AI for Piping Estimation
The Takeoff AI estimates from isometrics, P&IDs, and line lists by measuring lengths, counting fittings and welds, and building a complete MTO for labor and material pricing.
The Takeoff AI estimates projects the way you do
The Takeoff AI reads what actually arrives on the shared drive: PDFs. Clean vector sheets, scans, photocopies of photocopies. If you can open it, it can take off from it.
Get Your Free Piping TakeoffPipe and Instrument Takeoff
The Takeoff AI counts valves by their symbol on the piping and instrumentation diagram and reads the tag beside each one, so type, size and rating arrive attached to the count.
Isometric Takeoff
Derives lengths, fittings, flanges, valves, welds and spool breaks off each isometric, from both the bill of material table and the drawing.
General Arrangement
The Takeoff AI measures line runs off the scaled general arrangement and picks equipment positions off the plan, marking each length as measured so you can see which numbers came off the scale.
Line list + Pipe Class sheets
The Takeoff AI reads the line list and pipe class sheets as the specification, so every measured line comes back carrying its class, material, schedule and insulation.
Fittings, Flanges and Welds
The Takeoff AI counts elbows, tees, reducers and couplings by size and schedule, and flanges by rating and facing.
See The Job In 3D Before You Price It
ContraVault AI turns your 2D piping, structural and E&I sets into a 3D model, so your team can walk the assembly and catch clashes before the bid goes out.
Frequently asked questions
ASME B31.3 for process piping and B16.5 for flanges, with your own pipe class sheets layered on top. The counts are seeded on the codes you already estimate under - not guessed by a model that's never seen a class sheet.
Hours, against the weeks a manual takeoff runs. On an industrial piping package the grind is ~875 estimator-hours; theTakeoff takes it to ~300 - and most of those 300 are verification, not counting.
