How it works

  1. Send the plans. Text them on WhatsApp, upload on the web, forward the bid invitation by email, or let Field24 pull it from BuildingConnected, Merx or PlanHub.
  2. Answer two questions. Usually your scope and whether to price it.
  3. Review the takeoff on the sheet. Every row is marked where it was measured, so you can check it in seconds.
  4. Send the proposal. Priced with local material and labor rates, on your template, ready to sign.

How it measures

Field24 reads exact lengths from the PDF's vector layer, runs a wall detector on scanned sheets, counts openings and fixtures, and reads wall-type callouts for heights. Every quantity carries a mark on the drawing.

A general assistant: walls found as fragments
The same plan with each wall detected as one continuous run
Field24: each wall as one continuous run

How it prices

Home Depot prices for residential work, market rates from private cost databases for commercial work, labor rates adjusted to your ZIP or postal code, and your own price book first. The source is on every line.

After the takeoff

Send an addendum and the affected sheets are re-measured and re-priced. Field24 can draft, submit and revise the bid on BuildingConnected behind an Accept prompt you control, and once the job starts it writes change orders and finds the details you need on the plans.

Common questions

Who is Field24 for?

Subcontractors and general contractors who bid from plan sets and want the takeoff, pricing and proposal done in minutes instead of evenings.

Do I need to install anything?

No. Field24 works over WhatsApp, the web, the mobile app and email, and inside ChatGPT and Claude.
