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.
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.
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.
Bids, jobs, RFIs, vendors, Buildings and your crew cost nothing. Build Cloud runs on prepaid credit, with the price list in the open.
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.
Build also has a public side, where people share the work they are building. Explore it
