The list of solicitations will be refreshed at 3 p.m. each day.

Construction projects

The Iowa DOT's Purchasing Section does not provide plan holders names of potential prime contractors. Sets of plans and specifications for construction projects are now attached to the posted solicitation opportunity list. To the fullest extent possible, plan rooms will be utilized statewide for potential bidders to have the ability to print the solicitation, plans and specifications.
