What We do

Contracts is the focal point where all pre-letting activities converge so contracting can take place for construction. We are also responsible for two major functions of the Iowa Department of Transportation:

  • Estimating and contract letting.
  • Bid review, monitoring and collusion detection.

Attention iconCargo Preference Act – January 2016
The Cargo Preference Act (CPA) applies to equipment materials and commodities obtained using U.S. Government funds. When transported by ocean vessels, at least 50% of such items must be transported on privately owned United States-flag commercial vessels, if available.

The FHWA has determined the Cargo Preference Act (CPA) and the implementing regulations, 46 CFR Part 381, are applicable to the Federal-aid highway program. Therefore, the CPA requirements are effective for the Federal-aid highway program.
