Introduction
A mechanical takeoff is the count and measure of everything a mechanical contractor installs, taken from the bid drawings. It covers pipe by size and spec, duct by size, shape and gauge, and every fitting, valve, flange, damper, hanger and piece of equipment shown on the plans, isometrics and HVAC (heating, ventilation and air conditioning) sheets. That count becomes the material takeoff (MTO) and the labor takeoff the bid is priced from.
Most estimators still build it by hand. They set the scale on each sheet, trace every run with a length tool, click each fitting one symbol at a time and type the totals into a spreadsheet or an estimating database. On an industrial package of a few hundred sheets, that adds up to 40 or 50 hours before anyone prices a line.
That pace doesn't hold anymore, because fewer estimators are carrying more bids while data center and process packages keep getting larger.
The ten tools below are the mechanical takeoff software US contractors shortlist most often in 2026. Each entry says what the tool counts and measures for you and where the estimator is still working by hand, so you can pick the takeoff software for mechanical contractors that fits how your team bids.
What Mechanical Takeoff Software Counts And Measures
Mechanical takeoff software produces the quantities a mechanical bid is priced from, which are lengths, counts and the labor tied to them. On piping, that means pipe footage by size and spec, fittings, valves, flanges, gaskets, bolts and welds, with welds counted by diameter inch. On HVAC, it means duct length by size, shape and gauge, plus transitions, dampers, hangers and insulation, so most contractors looking for HVAC takeoff software end up on the same shortlist.
A mechanical quantity takeoff also picks up equipment from the schedules, such as pumps, air handlers and heat exchangers, along with the supports and racks around them. Older tools help you measure these items on screen, while newer AI tools count and measure them from the drawings and carry the count through to labor and pricing. Shops that bid mostly sheet metal can also look at our list of ductwork takeoff software.
Why Mechanical Estimators Can't Keep Clicking Every Fitting
Mechanical estimators are getting harder to find, and each one is carrying more bids. The Bureau of Labor Statistics (BLS) counts about 221,400 cost estimators in the US and projects a 4% decline by 2034, and roughly three in four estimator seats will need to be refilled over the decade. The Shortage of Estimators report lays out these numbers.
Mechanical takeoff has stayed manual through all of it, and it can't stay that way when a smaller team is clicking through every elbow and damper on every package. Data center work adds to the load, since chilled water piping and ductwork show up on nearly every job, and The Data Center Boom Has A Problem explains why. The Takeoff AI suits mechanical contractors expanding into data centers, because it turns those piping and HVAC packages around in hours.
What To Look For In Mechanical Takeoff Software
The right mechanical takeoff software counts and measures the drawings for you and lets you check every number before the bid goes out. Look for these four things.
- It counts fittings and measures pipe and duct runs from the drawings, so the estimator reviews quantities instead of clicking them.
- It covers piping, ductwork, plumbing and equipment in one project, across P&IDs, isometrics and plan sheets.
- Every quantity is marked on the sheet it came from, so a reviewer can trace any line back to its source.
- The takeoff carries through to a labor takeoff and a priced bill of materials (BOM), so nobody retypes quantities into another program.
10 Best Mechanical Takeoff Software In 2026
These are the 10 best mechanical takeoff software tools for 2026, starting with the one that does the takeoff and the pricing for you.
1. The Takeoff AI
The Takeoff AI is the best mechanical takeoff software in 2026. It estimates from your mechanical drawings, counts every fitting, valve, flange, gasket, bolt and weld, and measures each pipe run by size and spec and each duct run by size, shape and gauge. It is built on AI models trained on more than 1 million mechanical, HVAC and piping drawing sets, and it delivers 95% accuracy. Every number is marked and highlighted on the drawing it came from, so someone on your team can check it before the bid goes out.
113 estimators say The Takeoff AI is the best mechanical takeoff software and helps estimate projects in 3 to 4 hours that once took 40 to 50 hours, which gives back 90 to 95% of their estimating time. It creates priced bids from industrial drawings in under 4 hours. The output is a material takeoff, a labor takeoff and a priced BOM, with weld counts by diameter inch on piping scopes.
The Takeoff AI covers piping, P&ID (piping and instrumentation diagrams), isometrics, mechanical, electrical and instrumentation, plumbing, HVAC including ductwork, structural steel and misc iron. Nesting lays out cuts on stock pipe lengths and sheet to reduce offcut waste, and the platform builds a 3D model from 2D drawings. After the award, the same platform runs schedules, project controls and subcontractor management.

2. TaksoAI
TaksoAI is an AI takeoff tool built for commercial mechanical contractors, covering HVAC, piping, plumbing and mechanical insulation. Its computer vision picks out duct, pipe and plumbing fittings, splits runs by branch and size, and catalogs equipment across the plan set. The estimator reviews and approves each result, then exports the quantities to a separate estimating program for labor and pricing. It has very few public reviews so far, so there's little user feedback to go on.
3. Trimble AutoBid Mechanical
Trimble AutoBid Mechanical, which many shops still know by its older QuickPen name, pairs an on-screen takeoff module with automatic fitting generation tied to labor databases. The estimator traces each run on screen and the program fills in fittings and labor from there. Users in public reviews mention launch errors and add-on licenses they had to buy on top of the base program.
4. FastEST (FastPIPE And FastDUCT)
FastEST splits mechanical takeoff across two products, FastPIPE for plumbing and piping and FastDUCT for HVAC sheet metal. Both work point-and-click on PDFs, so the estimator still enters every run and fitting while a large fitting catalog handles the pricing behind it. FastDUCT users say the way duct totals roll up in the summary report takes some getting used to.
5. McCormick Estimating
McCormick Systems sells mechanical and plumbing estimating with a digital takeoff tool, Design Estimating Pro, that pulls from more than 40,000 preloaded items and prebuilt assemblies. Takeoff is point-and-click, and the estimator builds each run from the database. Reviewers mention a hard installation and a plumbing item library that needs more upkeep.
6. On-Screen Takeoff
On-Screen Takeoff from ConstructConnect is a general digital takeoff tool used across trades, mechanical included. Estimators set up a condition for each pipe or duct size and trace the runs on screen. The optional Takeoff Boost add-on brings in AI detection, but pipe and duct runs are still traced by hand. A complaint that comes up in reviews is poor backward compatibility between versions.
7. STACK
STACK is cloud-based takeoff and estimating software for most trades, and mechanical contractors use it for on-screen counts and lengths from any browser. Pipe and duct assemblies have to be built by the contractor, and every run is traced manually. Some users say missing tools such as a linear cut make revising a takeoff more work than it should be.
8. Bluebeam Revu
Bluebeam Revu is PDF markup software that a lot of mechanical estimators use for measuring. Its count and length tools are precise, but every run is traced and every fitting is clicked by hand, and with no mechanical pricing database the quantities move to another program for labor and pricing. Slowdowns on large drawing sets come up often in reviews.
9. PlanSwift
PlanSwift is a Windows desktop takeoff program where users drag assemblies onto the plan and the software tallies the quantities. Mechanical shops build their own pipe and duct assemblies, and all of the measuring stays manual. Reviewers point to a steep learning curve for new users.
10. Beam AI
Beam AI, from Attentive.ai, is an AI takeoff service for commercial trades that include HVAC and plumbing. Its AI pulls quantities from plan sets, and on the done-for-you service a review team checks the output before delivery, which can take 24 to 72 hours. The output stops at quantities, and one reviewer pointed to missing pricing features.
How The Takeoff AI Is Different
The Takeoff AI is the best mechanical takeoff software for contractors who need the takeoff done and priced in hours. It counts every fitting and measures every pipe and duct run from the drawings, where other tools leave the clicking to the estimator or stop at symbol counts. It then prices the takeoff into a priced BOM with labor. Every number is highlighted on the drawing it came from, so the estimator checks the work before bidding.
FAQs
What Is The Best Mechanical Takeoff Software In 2026?
The Takeoff AI is the best mechanical takeoff software in 2026 for contractors bidding piping, HVAC and plumbing work. It counts and measures every pipe run, duct run, fitting and valve from the drawings, and returns a material takeoff, a labor takeoff and a priced BOM with every count highlighted on its sheet.
How Long Does A Mechanical Takeoff Take With AI?
With The Takeoff AI, estimators finish mechanical takeoffs in 3 to 4 hours that once took 40 to 50 hours by hand. That saves 90 to 95% of their estimating time, and the hours go into checking scope and bidding more jobs.
Can Mechanical Takeoff Software Handle HVAC Takeoffs?
The Takeoff AI handles HVAC takeoffs in the same project as the piping, measuring duct by size, shape and gauge and counting transitions, dampers, hangers, gaskets and bolts. That means one tool covers the HVAC takeoff software job and the piping takeoff on a mechanical bid.
Does Mechanical Takeoff Software Give A Labor Takeoff?
The Takeoff AI produces a labor takeoff alongside the material takeoff, built from the fitting, joint and weld counts, with welds by diameter inch. Many manual mechanical takeoff tools only give quantities, and the estimator applies labor units in a separate estimating program.
How Do I Check An AI Mechanical Takeoff Before I Bid?
Open the takeoff next to the drawings and check the highest-cost lines first, such as valves, equipment and large-bore pipe. In The Takeoff AI, every quantity is highlighted on the sheet it came from, so clicking a line shows exactly where the number came from.
Conclusion
Mechanical takeoff is still mostly done by hand, and that can't last when fewer estimators are carrying more bids every year. The Takeoff AI is the best mechanical takeoff software for contractors who need the takeoff done and priced in hours.
