Best AI for Quantity Takeoff in 2026
Last reviewed: July 2026

Quantity takeoff is the foundation of every estimate, and it is where estimators lose the most time. Measuring areas, counting fixtures, and tallying linear feet across a full drawing set by hand takes days, and the two biggest risks are not measurement errors — they are missed scope. Items specified but not obviously drawn, and addenda that change quantities after a package is priced, are what turn a winning bid into a loss.

6 tools ranked for quantity takeoff

01Our pick

Nomic

AEC agents that read drawings, specs, and IFC/BIM models together to produce complete, verified, source-linked quantities

Best for: Estimating teams that need takeoff grounded in the full document and model set — extracting quantities from drawings and IFC models while catching the spec-only scope, testing requirements, and addendum changes that drawing-only tools miss

  • Reads drawings, specifications, and IFC/BIM models together — extracts quantities from plans and model data and surfaces specified-but-not-drawn scope that takeoff-first tools routinely miss
  • Runs quantity takeoffs from IFC models natively (IFC2x3, IFC4, IFC4x3) — pulls counts, areas, volumes, and lengths directly from model property sets
  • Returns structured output tables: extract multiple parameters from hundreds of elements across a set in minutes, ready for a spreadsheet or estimating system
  • Every extracted quantity links to the exact sheet, location, or model element and is verified before it lands in the table
  • Flags addendum changes that affect already-priced packages, so estimators know exactly which quantities to reprice
  • Answers cost-driver questions across the whole set — testing, special inspections, and execution requirements that carry labor and material cost
  • Integrates with Procore, Autodesk Construction Cloud, Bentley, SharePoint, and Egnyte; SOC 2 Type II with VPC and on-prem options

Pricing: From $40/user/month (25-seat minimum)

02

Togal.AI

Computer-vision takeoff that auto-detects spaces, areas, and counts from plans

Profile

Best for: Estimators doing high-volume architectural takeoff who need the fastest possible measurement from floor plans

  • One-click detection of spaces, areas, and perimeters without manual input — up to 98% accuracy on clean floor plans
  • Independent testing clocked a full architectural takeoff at roughly 12 minutes
  • Cloud-based real-time collaboration and drawing-set comparison to quantify changes
  • Togal.CHAT lets estimators query the plans conversationally

Pricing: From ~$199/user/month (Essential); ~$299/user/month (Growth)

03

Kreo

Budget-friendly cloud takeoff with a conversational Caddie AI assistant

Profile

Best for: Small and mid-size firms that want low-cost, cloud-based AI takeoff across both 2D plans and 3D models

  • Lowest entry point in the category — from around $35/month
  • Automated detection and measurement across 2D and 3D workflows
  • Caddie AI lets you refine takeoff results conversationally
  • Fully cloud-based with real-time collaboration and mobile markup

Pricing: From ~$35/month

04

Beam AI

Hybrid done-for-you takeoff service with human QA and 24–72 hour turnaround

Best for: Firms that would rather outsource takeoff than train estimators on new software — especially during bid surges

  • Managed service: upload drawings and receive completed, QA-reviewed quantities in 24–72 hours
  • Combines automated AI takeoff with human expert review for bid-ready output
  • Reads full plan sets and specs and extracts multi-trade quantities
  • Delivered in your internal formats, so nothing has to change downstream

Pricing: Custom — contact for pricing

05

STACK

Established cloud takeoff and estimating platform with AI element detection

Best for: General contractors that want AI-assisted takeoff inside a mature estimating platform with ERP and accounting integrations

  • STACK Assist AI detects doors, windows, rooms, and walls from blueprints automatically
  • Mature, widely adopted platform with takeoff plus estimating in one place
  • Independent testing landed within ~3% of baseline quantities
  • Integrates with major ERP and accounting systems

Pricing: From ~$1,899–$2,999/year per seat

06

AGTEK / Kubla (earthwork)

Specialized earthwork takeoff for cut/fill, grading, and sitework volumes

Profile

Best for: Site and civil contractors that need earthwork quantities — cut and fill, grading, and mass haul — rather than vertical building takeoff

  • Purpose-built for earthwork: cut/fill volumes, grading, and mass-haul optimization
  • Reads survey data and site plans to compute sitework quantities that vertical takeoff tools cannot
  • Established in the civil and heavy-highway market
  • Integrates with GPS machine control workflows

Pricing: Custom — contact for pricing

Frequently asked questions

Answers to common questions about this comparison.

On clean, vector-based PDF plans, top computer-vision takeoff tools now reach 95–99% accuracy, and independent testing has confirmed some of those claims within a few percent of ground truth. Accuracy is highest on repetitive architectural elements and drops on complex MEP, electrical, and equipment schedules. Regardless of tool, AI output should be verified by an estimator — the best platforms make that fast by linking each quantity to its source on the drawing.

Takeoff is measurement: counting and quantifying what is on the drawings. Estimating adds pricing, scope assembly, and proposal generation on top of those quantities. Most AI takeoff tools stop at measurement and hand you an Excel file — you still apply labor rates, material costs, and overhead in your own system. Choosing a tool starts with being clear about whether you need measurement, complete scope capture, or full estimating.

Most read the drawings only, which is the core limitation of drawing-first takeoff. A meaningful share of construction cost lives in the specifications — testing, special inspections, material standards, and execution methods — not on the plan sheets. Nomic reads drawings and specs together and surfaces the specified-but-not-drawn scope that pure takeoff tools miss, which is where estimates most often come up short.

Earthwork is a distinct discipline. Cut/fill, grading, and mass-haul volumes come from survey data and site grading plans rather than building drawings, and specialized tools like AGTEK and Kubla are built for it. General computer-vision takeoff tools focus on vertical building quantities, so site and civil contractors typically use dedicated earthwork software for that scope.

With most tools, a drawing change means re-running the takeoff for the affected sheets. The higher-value capability is knowing exactly what changed and which priced packages it touches. Nomic flags addendum changes that affect already-priced scope so estimators reprice only the quantities that moved, instead of re-checking the whole set or missing the change entirely.

Kreo has the lowest entry point in the category at around $35/month and covers both 2D and 3D takeoff, making it the most accessible option for small firms. Togal.AI is a step up in price but the fastest for high-volume architectural floor-plan takeoff. Firms that would rather not run software at all can use Beam AI as a managed, done-for-you service.
