Pre-Bid Meetings, RFIs, Addenda, and Bid Deadlines Explained
Most contractors watch the bid due date. The problem is that the dates before the bid due date can matter just as much. Miss a mandatory walk-through, RFI cutoff, or addendum acknowledgement and the bid can be rejected before anyone looks at price.
Before you price
Mandatory pre-bid meetings and site walks
Some RFPs require attendance at a pre-bid meeting or site visit. If attendance is mandatory, missing it can make your bid nonresponsive.
Track who attended, the sign-in requirements, and any notes that affect scope or access.
RFI and question deadlines
The question deadline is your last clean chance to resolve unclear scope, conflicting drawings, or risky terms before bids are due.
Waiting until the final estimate review is usually too late.
Addenda and acknowledgement requirements
Addenda can change drawings, specs, deadlines, forms, alternates, or price requirements. Many owners require bidders to acknowledge every addendum.
A missing addendum acknowledgement can sink an otherwise solid bid.
Bid delivery details
Confirm the exact delivery method, time zone, portal, envelope labeling, required copies, signatures, bid bond, and pricing form.
Treat bid delivery as a compliance item, not clerical cleanup.
