Measure the right geometry
Counts, linear measurements, areas, volumes, slopes, deductions, and repeated layouts differ by trade. Test the measurement types your bids actually use.

A construction takeoff converts issued drawings into counts, lengths, areas, volumes, and assemblies that can be priced. BuildVision AI provides a plan-linked first pass while keeping the estimator responsible for scale, scope completeness, revisions, and the approved quantities.
Working principles
Counts, linear measurements, areas, volumes, slopes, deductions, and repeated layouts differ by trade. Test the measurement types your bids actually use.
A reviewer should be able to move from a quantity to its drawing mark, sheet, detail, schedule, or explicit allowance.
Specifications, notes, testing, accessories, temporary work, waste, means and methods, and exclusions do not emerge from geometry alone.
Decision guide
Run a representative project and measure correction effort, not demo speed alone.
| Factor | What good looks like | How to verify it |
|---|---|---|
| Input quality | Support the PDF sizes, scans, drawing styles, sheet counts, and revisions the team receives. | Test clean vector plans, scans, mixed scales, rotated sheets, and an addendum set. |
| Measurement coverage | Handle the trade’s count, linear, area, volume, slope, and assembly needs. | Replay a completed bid and compare final quantities by measurement type. |
| Review controls | Let estimators select, inspect, correct, add, remove, and explain results. | Record false detections, missed scope, correction time, and the evidence retained. |
| Downstream handoff | Move approved quantities into pricing and proposal work without losing organization. | Follow one complete takeoff through cost build-up, approval, and issued proposal. |
Practical sequence
Confirm sheet issue, scale, scope, legends, schedules, details, and addenda.
Use AI-assisted or manual tools to count and measure visible plan scope.
Correct results and add specification, accessory, labor, waste, and risk requirements.
Freeze reviewed quantities for estimating, procurement inquiry, or proposal output.
In the product
Start a job and move its output into explicit review states.
Wait for the top-bar save state, then choose Run AI takeoff for the document and read stage/page progress.
For targeted symbol search, select a named count and choose Search more, or use Search more on an eligible EA symbol in Legend.
Use the canvas feedback and notification bell to follow the run, including plan-wide completion or no-match results.
Review dashed pending matches by group or selection; accept correct work and dismiss incorrect work.
Common questions
It includes plan-derived counts and measurements plus the material or assembly structure needed for pricing. Complete scope also requires notes, schedules, details, specifications, waste, and estimator assumptions.
No. AI can propose visible counts and measurements, but an estimator must verify scale, detections, revisions, cross-references, specifications, and anything not shown directly.
Takeoff quantifies the scope. Estimating applies material, labor, equipment, subcontract, indirect cost, risk, overhead, and markup to produce a price.
Verify current product capabilities, material systems, code requirements, commercial terms, and local pricing with the responsible vendor, designer, contractor, or authority.
