The Commercial Construction Bidding Process Explained
The commercial bidding process can take anywhere from 2 weeks to 4 months depending on the project size, delivery method, and owner. Understanding each stage — and what's actually expected of you at each one — is the difference between winning consistently and burning your estimating team out chasing dead deals.
Invitation to bid and prequalification
Public projects publish ITBs through state procurement portals; private projects come through Dodge, ConstructConnect, or direct invitation. Prequalification packages typically require 3 years of financials, bonding letter, safety records, and project references. Get this packet templated — you'll send it 50+ times per year.
Bid package review and RFI period
Once you have plans and specs, you have a defined window (usually 2–4 weeks) to ask Requests for Information. Smart GCs read the full spec book in the first 48 hours and submit RFIs early. Late RFIs rarely get answered before bid day.
Subcontractor solicitation and quote management
Send RFPs to 3–5 subs per trade. Track who's bidding, addenda acknowledgments, and quote due dates (always 24–48 hours before your bid is due). This is where bid management software pays for itself.
Estimate assembly and risk loading
Roll up sub quotes, self-perform labor, materials, equipment, GC's GCs, bond, insurance, and contingency. Apply a markup that reflects your actual risk on this project — not a flat 8% across the board.
Submission, opening, and award
Public bids are read aloud; private bids are scored on price plus qualifications. Award typically takes 2–6 weeks. Use that time to start mobilization planning on bids you feel strong about.
Bottom line
Winning more bids isn't about bidding more — it's about bidding the right ones with full information. Disqualify bad-fit RFPs early and pour estimating capacity into the deals you can actually win.
