The Office of Contracts is responsible for two major functions of the Iowa Department of Transportation:

Icon8in1 contractor poster

Effective with the April 19, 2016 Letting, the Office of Contracts will no longer be mailing the 8in1 poster with the signed contracts. These posters have been placed online individually and combined into one single PDF document on the civil rights website. This is a good resource for both DOT construction personnel and contractors.
