Construction Takeoff AI for the Toughest Plan Sets, Bids, and Estimating Teams

  • Deploy Anywhere, Run Everywhere

    Run construction takeoff on PDF plan sets, scanned drawings, and sheet images, in the cloud, in your VPC, on-prem, or via API inside your estimating software.

  • One Platform, Full Adoption

    Tools every preconstruction team can adopt, from estimators and project engineers to trade subcontractors and the product teams building takeoff software, no separate ML team required.

  • Secure, Compliant, and Audit-Ready

    Data stays safe with SOC 2 Type II compliance, encrypted data, HIPAA compliance, and an uptime SLA, with a marked-up sheet behind every count and quantity.

  • Electrical Devices & Light Fixtures
  • Plumbing Fixtures & Fittings
  • Doors, Windows & Openings
  • Room & Floor Area Takeoff
  • Wall, Pipe & Conduit Lengths
  • Schedules, Tags & Title Blocks

Take Off Every Sheet, from the Cover Page to the Last Detail

Add an automated takeoff layer to every bid with Roboflow vision AI for construction takeoff. Built for general contractors, trade subcontractors, and the software teams building estimating tools, where one plan set can run to hundreds of sheets, bid deadlines don't move, and a missed fixture or a double count shows up as lost margin after award.

Count every item:

  • Detect and count electrical devices, light fixtures, plumbing fixtures, HVAC diffusers, and structural callouts, with symbol detection models trained on your own legends.
  • Split large sheets into overlapping tiles so small, dense symbols are caught, then stitch results back onto the full sheet so nothing is counted twice.
  • Classify look-alike symbols, such as duplex and GFCI receptacles, so each count rolls up to the right line item.

Measure the plans:

  • Segment rooms, floor areas, and walls, and convert them to square feet and linear feet using the sheet's drawing scale.
  • Trace wall, pipe, duct, and conduit runs for linear takeoffs by trade.
  • Read door and window tags, room names, schedules, and title blocks with OCR, so every count ties to a sheet number, room, and spec.

Build the estimate:

  • Return quantities as structured data by trade, sheet, and room, ready for your estimating spreadsheet or bid software.
  • Mark up every detection on the sheet, so estimators check a finished takeoff instead of starting from a blank one.
  • Run whole plan sets at once with batch processing, and rerun the revised sheets when an addendum lands.

Bring intelligence to every bid today. Get a marked-up, line-item takeoff for the whole plan set before the first estimator opens it.

Frequently asked questions

What is construction takeoff with Vision AI?

Construction takeoff with Vision AI runs trained computer vision models (opens in a new tab) on plan sets to find and count symbols, segment rooms and areas, trace linear runs, and read tags and schedules. The result is a quantity list by trade, sheet, and room, with every item marked up on the drawing.

What drawings and files does it work with?

Vector and scanned PDF plan sets, sheet images, and photos of paper drawings, across architectural, electrical, plumbing, mechanical, and structural sheets. Models are trained on your own drawings, so they learn your symbol legends and drafting styles.

How does it handle large sheets with small, dense symbols?

Each sheet is split into overlapping tiles, every tile runs through the detector at full resolution, and the results are stitched back into one sheet with duplicates removed, so a small symbol on a full-size sheet is caught the same as a large one.

Can it integrate with our estimating software?

Yes. Roboflow returns counts, measurements, and marked-up sheets over a REST API (opens in a new tab) or webhooks, so takeoff results flow into estimating, bid management, and preconstruction tools, or into the product your team is building.
