Downtobid is an AI tool for commercial construction that automates routine steps in bidding and tender workflows. It’s designed for general contractors and subcontractors who need to review project documents faster and manage invitations to bid (ITBs) more accurately.
ITB and bid package automation
General contractors can upload plans and specifications, and the system turns them into structured scopes of work with supporting notes, then prepares an ITB package for distribution. This helps reduce prep time and lowers the risk of missing key line items in estimates or work descriptions.
One workspace for subcontractors
Subcontractors get a single view of invitations, deadlines, and requests for information (RFIs), instead of tracking everything across scattered email threads.
- Centralized ITBs and RFIs in one board
- Clear visibility into deadlines and priorities
- Faster responses based on organized project data
Alternative to traditional bid platforms
Downtobid positions itself as an alternative to BuildingConnected, iSqFt, PlanHub, and SmartBid, with a focus on using AI to clean and structure project information to save manual work and improve bid accuracy.
