Construction Bidding Software
Build an AI-assisted estimate, invite subcontractors from the network to a bid room, and turn the winning number into a branded proposal and an e-signable contract.

- Itemized CSI estimate with material / labor / equipment
- Full takeoff with computed quantities
- Code-compliance check (CBC/IBC/UBC), section-cited
