A DOT letting moves on fixed dates, and the pre bid meeting, the question deadline, and the addenda that revise the proposal all fall in a tight window before bids are due. Missing one can cost the bid.
What the letting timeline carries
A DOT letting sets a pre bid meeting, a deadline for questions, and a series of addenda that revise the plans, proposal, and quantities before the bid date, and a bidder usually must acknowledge every addendum to be responsive. The pre bid meeting can carry information that changes the bid, and a late addendum can move quantities or the date. These events cluster in the days before letting.
Why these deadlines are easy to miss
The pre bid meeting date, the question deadline, and the addenda post to the letting and plans system, sometimes by notice to plan holders, and a contractor tracking many lettings can miss a late addendum that changed quantities or a meeting that was mandatory. The acknowledgment requirement sits in the proposal, not the title.
How an AI bid agent catches the timeline
An AI bid agent monitors each letting the contractor is pursuing, surfaces the pre bid meeting, the question deadline, and every addendum as it posts, and flags what changed and the acknowledgment requirement. The bid team works from the latest documents without refreshing the plans system by hand.
