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 Only AI Built For Piping Estimators
The Takeoff AI traces every count and every measurement back to the drawing.
Click any number in the MTO and it shows you exactly where on the iso it came from, so you verify instead of trust.

TheTakeoff 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.
Pipe 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.
The Takeoff AI carries the iso all the way to cost
The Takeoff AI first runs a material takeoff from your isometrics, then derives the hardware nobody draws, estimates labor hours, and prices it all so you get a number you can bid.
Save 70% of Estimation Time
The Takeoff AI extracts quantities, derives hardware, prices material off your rate book, and estimates labor hours against MCAA-seeded units with your own factors on top.
Every number traces back to the iso it came from.

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.
PDFs, native or scanned. CAD. 3D model exports where they exist. Real bid packages are messy - mixed revisions, scanned sheets, drawings that were faxed at some point in their life. That's the normal case, and the engine is built for it.
Off the branch table in your pipe class sheet - which is the only place the answer actually lives. The engine resolves the branch type from the class and the line sizes either side of it, rather than trying to read intent off the symbol.
Lengths come from isometrics and scaled general arrangements. They do not come from P&IDs - a P&ID isn't to scale, and any tool that claims a length off one is guessing. When the package has isos, theTakeoff reads lengths and spool breaks off them directly.
Yes. Show the engine one instance and it finds the rest across the set. Every drawing office has its own legend, and no model ships knowing yours.
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.
Excel-native, evidence-linked, mapped to your template. The quantities land in the format your pricing sheet already expects.
No. Packages run to hundreds of sheets and that's the design point - the bigger the set, the more the manual approach breaks down.
Your drawings stay yours. ISO 27001-certified infrastructure, and your project data is never used to train models for anyone else.
SecurityYour bid data stays private.
TheTakeoff AI is built for sensitive bid packages, with access controls, encryption, and audit trails so your team can work fast and securely.
