For subcontractors and suppliers

Get invited to the work you actually bid

Register once for the CSI scopes you self-perform. General contractors estimating on Axiom search the network when they build bid lists, then send you a private bid room with every drawing, spec, and addendum — no zip files, no shared inboxes.

Pick your CSI codes

Register for every division you price — from 03 Concrete to 26 Electrical. GCs filter bid lists by these exact codes.

Set your regions

Tell us where you travel. You only hear about work you'd actually bid.

Upload compliance docs

W-9, certificate of insurance, licenses, and safety letters stay on file so prequalification isn't a fire drill.

Get invitations to bid

Each invitation opens a private bid room with drawings, specs, and addenda. Confirm intent, download, and upload your proposal.

Registration is free for subcontractors

There's no charge to be listed, receive invitations, or submit proposals. You control whether your company appears in the directory and can opt out at any time.
