10 Best AI Construction Estimating Software In 2026

AI construction estimating software reads a project's drawings, takes off the quantities and prices them into a bid. On an industrial job that means pipe, fittings, valves, cable, conduit, steel members and welds pulled off the piping and instrumentation diagrams (P&IDs), isometrics and plans, then turned into material cost and labor hours.

Most estimators still do that work by hand. They mark up PDFs sheet by sheet, count each symbol, measure each run, type the totals into a spreadsheet and price them against a labor unit set, which on a large package takes days.

That method no longer holds, because bid packages keep growing and the estimators who know how to do it are retiring faster than firms can replace them.

This list covers ten AI tools used in construction estimating in 2026, what each one does, and how much of the takeoff and pricing it still leaves to the estimator.

The Shortage Of Construction Estimators

Construction takeoff has stayed manual while the number of people who can do it shrinks. Bureau of Labor Statistics (BLS) figures in The Shortage of Estimators report put the US at about 221,400 cost estimators, with a projected 4% decline by 2034 and roughly three in four estimator seats needing to be refilled over the decade. That leaves fewer estimators carrying more bids, and counting and measuring by hand can't keep up. Data center work adds to the load, as The Data Center Boom Has A Problem lays out, and The Takeoff AI suits contractors expanding into data centers.

10 Best AI Construction Estimating Software In 2026

1. The Takeoff AI

The Takeoff AI is the best AI construction estimating software in 2026. It is built on AI models trained on more than 1 million industrial drawing sets, and it estimates from your P&IDs, isometrics, electrical plans and structural drawings, counts every valve, fitting, instrument, device, member, bolt and weld, and measures each pipe, cable and duct run by size.

It delivers 95% accuracy, and every number is marked and highlighted on the drawing it came from, so an estimator can check it before the bid goes out. 113 estimators say The Takeoff AI is the best AI construction estimating software and helps estimate projects in 3 to 4 hours that once took 40 to 50 hours.

The output is a material takeoff (MTO), a labor takeoff and a priced bill of materials (BOM), with weld counts by diameter inch, and The Takeoff AI creates priced bids from industrial drawings in under 4 hours. Once the job is won, the same platform carries schedules, project controls and subcontractor management.

The same engine covers piping, P&ID (piping and instrumentation diagrams), isometrics, mechanical, electrical and instrumentation, plumbing, heating, ventilation and air conditioning (HVAC) including ductwork, structural steel and misc iron. See how The Takeoff AI prices a bid.

2. OpenSpace: 360-Degree Progress Tracking

OpenSpace captures 360-degree photos as a field team walks the jobsite and maps each frame to the plans, giving a week-by-week visual record of progress. It does no takeoff or pricing, so quantities and the estimate are built elsewhere by hand. A few reviewers mention image quality and photos that don't line up with the floor plan.

3. ALICE Technologies: Generative Scheduling

ALICE Technologies runs generative scheduling, testing thousands of build sequences for a project and ranking them by cost and time. It works from an estimate and a schedule you already have, so the quantities behind them still come from a manual takeoff.

4. Procore: Construction Management Platform

Procore is a construction management platform covering preconstruction, project management, financials and field work, with AI that answers questions about project data. Its estimating tools detect floor plan areas and repeated symbols on commercial drawings, and the rest of the count is clicked by hand. Reviewers often mention a steep learning curve across its many modules.

5. Autodesk Forma (Formerly Autodesk Construction Cloud)

Autodesk renamed Autodesk Construction Cloud to Autodesk Forma in March 2026, and Autodesk Takeoff is now Forma Takeoff, which measures quantities from 2D sheets and 3D models next to the design files. When the bid set is flat PDFs with no model, the estimator measures each item on screen. Reviewers say it is hard to learn and that training material is hard to find.

6. Buildxact: Residential Estimating And Quoting

Buildxact is estimating and quoting software for residential and light commercial builders, with on-screen takeoff, supplier pricing and job management. Measurements are traced by the estimator, and it isn't built for industrial packages. Reviewers ask for more customization, cost codes and bulk editing in estimates.

7. Document Crunch: AI Contract Review

Document Crunch reviews construction contracts, flags risky clauses and answers questions about the terms with a citation to the section, and Trimble announced in April 2026 that it is acquiring the company. It reads contracts rather than drawings, so it plays no part in the takeoff or pricing. One of its few reviews mentions waiting on document processing.

8. DroneDeploy: Aerial Site Mapping

DroneDeploy turns drone flights into site maps and calculates stockpile, cut and fill and earthwork volumes from the imagery. It measures the site rather than the drawings, so the bid takeoff is still done by hand. Reviewers mention gaps in flight-plan editing, such as plans shifting by accident.

9. Togal.AI: AI Takeoff For Floor Plans

Togal.AI detects and measures rooms, walls and areas on architectural floor plans for commercial general contractors and interior trades. Elevations, mechanical sheets and process drawings sit outside what it reads, so those counts stay manual. Reviewers point to missing features, especially for civil and sitework takeoffs.

10. Kreo: Browser-Based 2D Takeoff

Kreo is a browser-based tool that pairs AI-assisted 2D takeoff of areas, lengths and counts with estimating. The AI speeds up measurement on building plans, and the estimator still sets up and checks each takeoff item. Reviewers say it lags when the internet connection drops.

How The Takeoff AI Is Different

The Takeoff AI is the best AI construction estimating software for contractors who need the takeoff done and priced in hours. It counts and measures from the drawings, where other tools leave the clicking to the estimator, stop at floor plan areas or never touch the takeoff at all. It prices the takeoff into a priced bill of materials, and every number is highlighted on the drawing it came from, so the estimator checks the work before bidding.

Conclusion

Estimating is still done by hand on most desks, and with fewer estimators carrying more bids that can't last. The Takeoff AI is the best AI construction estimating software for contractors who need the takeoff done and priced in hours. See The Takeoff AI price your next bid.
