One shared 3D model for every company on a job, simple enough for every sub and GC, with the plans, bids and RFIs on it. The owner, the architect and engineers, the GC, every trade, the suppliers, the detailers and the crew work from the same plans and the same model.

What does Build do for a steel subcontractor?

Build reads the plan set, does the steel takeoff, models it in 3D and prices it, then drafts the proposal. You check the marks, the price and anything that goes out.

What about other trades?

Every trade gets its sheets marked, the shared model, bids and RFIs today, and PlanReader has takeoff presets for concrete, electrical and mechanical. Counts and quantities for plumbing, fire and finishes are planned.

Do the companies I send work to have to pay?

No. What you send is free to open and free to answer: no seat, no trial, no clock. A 3D model or a price request opens without an account at all.

What does Build cost?

Build is free for your company. Agents you run yourself cost nothing from Build; Build Cloud runs on prepaid credit. The price list is on the pricing page.

Every company on a job

Made for each company on the job.

One plan set and one model, and each company sees its own part of it: its sheets, its scope, its bids and the questions waiting on it. Here is what Build does for each one today.

The companies you work with pay nothing to answer you.

No seat, no trial, no clock.

What you send is free to open and free to answer. A 3D model or a price request opens without an account at all; an account only saves your own work.

Your agent, connected

Connect Claude Code, Codex or another agent through Build’s MCP. It comes with every account, and agents you run yourself cost nothing from Build.

Free to run your company. Agents cost what they use.

Bids, jobs, RFIs, vendors, Buildings and your crew cost nothing. Build Cloud runs on prepaid credit, with the price list in the open.
