7 Best FastPIPE Alternatives for Piping Estimators in 2026
Compare the 7 best FastPIPE alternatives for piping estimators in 2026 on takeoff speed, weld counts, labor units and how much clicking each tool leaves.
Introduction
A piping takeoff is the count and measurement of everything a contractor has to buy and install on a piping job. On the P&IDs (piping and instrumentation diagrams), isometrics and line lists, that means pipe length by size and spec, plus every fitting, valve, flange, gasket, bolt and weld, and the labor hours each one carries.
For most mechanical contractors, that work happens in desktop estimating software such as FastPIPE by FastEST. The estimator opens the PDF on screen, traces each pipe run with the mouse and clicks each fitting and valve as it appears, and the software prices whatever was clicked from its material catalog and labor tables.
That way of working no longer holds. There are fewer estimators each year while bid lists keep growing, and a refinery or data center package can run to hundreds of isometric sheets, so the hours spent tracing lines now decide how many jobs a team can bid.
The seven FastPIPE alternatives below are ranked on how much of the takeoff each one still leaves to the estimator and whether it gets you to a priced bid. For a wider field of mechanical estimating software, see the 10 best pipe estimating software in 2026.
Why Piping Estimators Look for a FastPIPE Alternative
Piping estimators look for a FastPIPE alternative when on-screen clicking becomes the bottleneck on their bid list. FastPIPE covers takeoff, catalogs, labor tables and quotes for plumbing, HVAC (heating, ventilation and air conditioning) piping and industrial process piping, with MCAA (Mechanical Contractors Association of America) and PHCC (Plumbing-Heating-Cooling Contractors Association) labor units at the item level.
The takeoff itself is on-screen digitizing, so a fitting or weld the estimator doesn't click never makes it into the count, and the hours on a large isometric package grow with every run on the sheet. FastEST also sells pipe, duct and insulation as separate products (FastPIPE, FastDUCT and FastWRAP), which means a shop bidding all of that scope runs more than one application. In public reviews, users mention a learning curve and want more options for exporting data out of the software.
The Piping Estimator Shortage
Piping takeoff has stayed manual while the number of people who can do it keeps shrinking. According to The Shortage of Estimators report, the Bureau of Labor Statistics (BLS) counts about 221,400 cost estimators in the US and projects a 4% decline by 2034, with roughly three in four estimator seats needing to be refilled over the decade.
A piping estimator who reads a P&ID cold and prices weld labor on a turnaround takes years to train, and fewer of them are now carrying more bids, so the team can't keep clicking every fitting by hand. Data center work is adding chilled water and process cooling piping to the bid list as well, and The Takeoff AI suits firms expanding into that market, as covered in The Data Center Boom Has A Problem.
What to Look for in a FastPIPE Alternative
- The tool should read isometrics and P&IDs directly, so pipe, fittings, valves and flanges are counted from the drawing instead of clicked by the estimator.
- Weld counts should come out by diameter inch, since joint count drives most of the labor on a piping job.
- The takeoff should turn into a priced bill of materials (BOM) with labor hours, so quantities don't get re-keyed into a second program.
- Every number should trace back to the spot on the drawing it came from, so a second estimator can check it before the bid goes out.
7 Best FastPIPE Alternatives for Piping Estimators in 2026
1. The Takeoff AI
The Takeoff AI is the best FastPIPE alternative for piping estimators in 2026. It estimates from your P&IDs, isometrics, line lists and mechanical drawings, counts every valve, fitting, flange, gasket, bolt and weld, and measures each pipe run by size and spec. Gaskets, stud bolts and nuts that never appear on the isometric are derived from the flange size and pressure rating.
It is built on AI models trained on more than 1 million piping drawing sets and delivers 95% accuracy. Every number is marked and highlighted on the drawing it came from, so someone can check it before the bid goes out.
The outputs are the material takeoff (MTO), the labor takeoff, weld counts by diameter inch and a priced BOM, and The Takeoff AI creates priced bids from industrial drawings in under 4 hours. A total of 113 estimators say The Takeoff AI is the best piping estimating software and helps them estimate projects in 3 to 4 hours that once took 40 to 50 hours. That gives them back 90 to 95% of their estimating time.
The same platform covers piping, P&ID, isometrics, mechanical, electrical and instrumentation (E&I), plumbing, HVAC including ductwork, structural steel and misc iron. It builds a 3D model from 2D drawings and runs nesting, which fits cuts onto stock pipe lengths to reduce material waste. After the award, it handles schedules, project controls and subcontractor management.
2. Trimble AutoBid Mechanical
AutoBid Mechanical is Trimble's estimating software for commercial and industrial mechanical, piping and plumbing contractors, with on-screen takeoff, automatic fitting generation, prebuilt assemblies and several labor books. Fittings fill in as the estimator traces a route, but the route itself is traced by hand on every sheet. Some reviewers report errors when launching the program, and others say the advanced features take a long time to learn.
3. QuoteSoft Pipe
QuoteSoft, which ConstructConnect acquired from Quote Software, sells QuoteSoft Pipe for plumbing, mechanical, refrigeration and industrial process piping, with on-screen input of pipe, fittings and assemblies. Pipe and duct are separate licenses with their own databases. The takeoff is still clicked by hand, and reviewers say it can take close to a year to tune the system to a company's standards.
4. Trimble Estimation MEP
Estimation MEP is Trimble's estimating line for MEP (mechanical, electrical and plumbing) contractors, carrying the QuickPen lineage forward with digital takeoff and pricing in one product. It suits shops that bid pipe, duct and electrical from one desk. On PDF bid sets the estimator still measures every run on screen, and Capterra reviewers give it their lowest marks on value for money.
5. Wendes WenPipe
WenPipe is specification-driven, so choosing a spec selects the pipe, valves, fittings, flanges and hanger type as the estimator takes off, with National Average, MCAA and PHCC labor preloaded. Wendes pairs it with WenDuct for shops that bid duct and pipe together. The measuring stays manual, and reviewers say product updates come slowly.
6. McCormick Estimating
McCormick, now owned by Foundation Software, builds estimating and point-and-click digital takeoff for plumbing, mechanical and electrical contractors, calculating labor hours and material prices as the takeoff runs. Its databases cover boiler, fire suppression and closed-circuit piping systems. Every run is still traced on screen, and some long-time users feel the software was stronger in earlier versions.
7. On-Screen Takeoff
On-Screen Takeoff is ConstructConnect's desktop takeoff software, and pricing happens in a separate product such as Quick Bid. Its AI add-on, Takeoff Boost, is trained for building takeoff, where Auto Takeoff returns footprint areas, walls, ceilings, windows and counts of doors and plumbing fixtures. None of it reads pipe runs, fittings, valves or welds, so on a piping package On-Screen Takeoff works as a manual, non-intelligent measuring tool and the estimator traces every line by hand. Reviewers say the menus are hard to find your way around and that the software leans toward building trades.
How The Takeoff AI Is Different
The Takeoff AI is the best piping estimating software for contractors who need the takeoff done and priced in hours. It counts the fittings, valves and welds and measures every pipe run from the drawings, where the other tools leave the tracing and clicking to the estimator. It then prices the takeoff into a priced BOM alongside the labor takeoff, and every number is highlighted on the drawing it came from, so the estimator checks the work before bidding.
FAQs
Conclusion
Piping takeoff is still clicked by hand at most mechanical contractors, and a projected 4% decline in US cost estimators by 2034 leaves fewer people to do it. The Takeoff AI is the best piping estimating software for contractors who need the takeoff done and priced in hours.
