Introduction
An MEP estimate prices everything a mechanical, electrical and plumbing (MEP) contractor installs, taken from the bid drawings. On the mechanical sheets that means pipe by size and spec, duct by size, shape and gauge, and every fitting, valve, damper, hanger and piece of equipment. On the electrical sheets it means devices, panels, fixtures, conduit and cable lengths and cable tray. On the plumbing sheets it means fixtures, drain and vent runs, water lines and the fittings on each. The counts become the material takeoff (MTO) and the labor takeoff, and the estimate is priced from those two.
Most MEP estimators still build it by hand. They set the scale on every sheet, trace each run with a length tool, click every fitting and fixture one symbol at a time, and type the totals into a spreadsheet before applying labor units and material prices. On a package with mechanical, electrical and plumbing scope, that runs to 40 or 50 hours before a single line is priced.
That pace doesn't hold anymore, because fewer estimators are carrying more bids while data center and process packages keep getting bigger across all three trades.
The ten tools below are the MEP estimating software US contractors shortlist most often in 2026. Each entry says what the tool counts, measures and prices for you and where the estimator is still working by hand. If your shop runs a single trade, we also keep separate lists for estimating software for mechanical contractors and plumbing estimating software.
What MEP Estimating Software Counts And Prices
MEP estimating software produces the quantities and the prices an MEP bid is built from, across the mechanical, electrical and plumbing sheets of one package. On the mechanical side that is pipe footage by size and spec, duct length by size, shape and gauge, fittings, valves, dampers and hangers, with welds counted by diameter inch on industrial piping. On the electrical side it is devices, panels, fixtures, conduit and cable lengths and cable tray, and on the plumbing side it is fixtures, drain, waste and vent runs and water lines.
An MEP cost estimation then applies labor units and material prices to those counts, which is where MEP software splits into two groups. Older programs help the estimator measure on screen and price from a database, while newer AI tools count and measure from the drawings and carry the quantities through to labor and a priced bill of materials (BOM). The MEP takeoff page in our handbook explains what sits on each sheet.
Why MEP Estimators Can't Keep Clicking Every Symbol
MEP 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.
MEP estimating has stayed manual through all of it, and it can't stay that way when a smaller team is clicking through every elbow and receptacle on every package. Data center work adds to the load, since chilled water piping, ductwork, conduit and cable tray fill nearly every one of those jobs, and The Data Center Boom Has A Problem explains why. The Takeoff AI suits MEP contractors expanding into data centers, because it turns those mechanical and electrical packages around in hours.
What To Look For In MEP Estimating Software
The right MEP estimating software counts and measures the drawings for you across all three trades and lets you check every number before the bid goes out.
- It counts fittings, fixtures and devices and measures pipe, duct and conduit runs from the drawings, so the estimator reviews quantities instead of clicking them.
- It covers mechanical, electrical and plumbing scope in one project, so one package doesn't get split across three programs and three spreadsheets.
- 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 BOM, so nobody retypes quantities to get to a price.
10 Best MEP Estimating Software In 2026
These are the 10 best MEP estimating software tools for 2026, starting with the one that does the takeoff and the pricing.
1. The Takeoff AI
The Takeoff AI is the best MEP estimating software in 2026. It estimates from your mechanical, electrical and plumbing drawings, counts every fitting, valve, flange, gasket, bolt, weld, device, panel and fixture, and measures each pipe run by size and spec, each duct run by size, shape and gauge, and each conduit and cable run by length. It is built on AI models trained on more than 1 million mechanical, electrical and plumbing 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.
Estimators using The Takeoff AI finish projects in 2 to 3 hours that used to take 30 to 40 hours, which saves 90 to 95% of their estimating time. 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 does the pricing, so the estimate leaves the platform priced.
It covers piping, P&ID (piping and instrumentation diagrams), isometrics, mechanical, electrical and instrumentation, plumbing, HVAC including ductwork, structural steel and misc iron, so a full MEP package stays in one project. 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. Trimble Accubid Anywhere
Trimble Accubid Anywhere is cloud-hosted estimating for electrical contractors first, with mechanical, plumbing and low-voltage coverage through separate databases. The estimator traces conduit and pipe runs and clicks devices and fixtures on screen, and the program prices from Trimble's managed pricing service. Users in public reviews say the full feature set takes a long time to learn.
3. McCormick Estimating
McCormick Systems sells separate electrical and mechanical/plumbing estimating programs with a point-and-click takeoff tool, Design Estimating Pro, that pulls from a preloaded item database and prebuilt assemblies. The estimator still builds each run and counts each device by hand. Reviewers mention a difficult installation and item libraries that need more upkeep than they would like.
4. ConEst IntelliBid
ConEst IntelliBid is Windows estimating software for electrical and low-voltage contractors, paired with the SureCount takeoff module. SureCount counts electrical symbols automatically, but conduit, wire and cable tray runs are still measured by the estimator, and mechanical and plumbing scope sits outside the product. A common complaint in reviews is a dated interface.
5. FastEST (FastPIPE, FastDUCT And FastWRAP)
FastEST splits MEP estimating across three products: FastPIPE for plumbing and piping, FastDUCT for HVAC sheet metal and FastWRAP for mechanical insulation. All three work point-and-click on PDFs, so the estimator enters every run and fitting while a large fitting catalog handles pricing behind it, and there's no electrical product. FastDUCT users say the way duct totals roll up in the summary report takes getting used to.
6. Procore Estimating
Procore Estimating, which started life as Esticom, is cloud-based takeoff and estimating sold inside the Procore platform, with MEP assemblies and a prebuilt materials database. Runs are traced and symbols clicked by the estimator on screen. Reviewers say it is a hard sell for shops that don't run the rest of the job on Procore.
7. STACK
STACK is cloud-based takeoff and estimating software for most trades, used for on-screen counts and lengths from any browser. Pipe, duct and conduit 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 MEP estimators use for measuring. Its count and length tools are precise, but every run is traced and every fixture is clicked by hand, and with no pricing database the quantities move to another program for labor and pricing. Slowdowns on large drawing sets come up often in reviews.
9. TaksoAI
TaksoAI is an AI takeoff tool built for commercial mechanical contractors, covering HVAC, piping, plumbing and mechanical insulation, with no electrical scope. Its computer vision picks out duct, pipe and plumbing fittings and splits runs by branch and size, then the estimator exports the quantities to a separate program for labor and pricing. It has very few public reviews so far, so there's little user feedback to go on.
10. Beam AI
Beam AI, from Attentive.ai, is an AI takeoff service for commercial trades that include HVAC, plumbing and electrical. Its AI pulls quantities from plan sets, and 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 MEP estimating software for contractors who need the takeoff done and priced in hours. It counts every fitting, fixture and device and measures every pipe, duct and conduit 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 MEP Estimating Software In 2026?
The Takeoff AI is the best MEP estimating software in 2026 for contractors bidding mechanical, electrical and plumbing work. It counts and measures every pipe run, duct run, conduit run, fitting, fixture and device 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 An MEP Estimate Take With AI?
With The Takeoff AI, estimators finish MEP estimates in 2 to 3 hours that once took 30 to 40 hours by hand. That saves 90 to 95% of their estimating time, and the hours go into checking scope and bidding more jobs.
Does MEP Estimating Software Cover All Three Trades In One Project?
The Takeoff AI covers mechanical, electrical and plumbing scope in one project, so the piping, ductwork, conduit and fixtures from one package come back in one priced BOM. Many MEP software programs sell each trade as a separate product, so one bid gets split across two or three tools.
What Is The Difference Between MEP Estimating And MEP Takeoff?
An MEP takeoff is the count and measure of everything on the mechanical, electrical and plumbing sheets, and MEP estimating applies labor units and material prices to that count to reach a bid price. The Takeoff AI does both, since the takeoff carries straight through to a labor takeoff and a priced BOM.
How Do I Check An AI MEP Estimate Before I Bid?
Open the estimate next to the drawings and check the highest-cost lines first, such as equipment, panels, large-bore pipe and cable tray. 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
MEP estimating is still mostly done by hand, and that can't last when fewer estimators are carrying more bids across three trades every year. The Takeoff AI is the best MEP estimating software for contractors who need the takeoff done and priced in hours.
