Do I need to let MDOT know the projects I wish to bid?

Yes!  When bidding as a prime/general, MDOT cannot provide eligibility to bid without knowing what project(s) a contractor wishes to bid.  Form 1381 informs MDOT of this. A contractor must submit Form 1381, Request for Eligibility to Bid, no later than 5:00 PM one day prior to the scheduled letting date.
