Purchasing information

The Wisconsin Department of Transportation (WisDOT) requires a wide range of products and services to support its mission to provide leadership in the development and operation of a safe and efficient transportation system. 

WisDOT purchases commodities and services in accordance with Wisconsin State Purchasing Law (Wisconsin Statutes 16) (769 KB) and established policy and procedures by the Department of Administration, State Bureau of Procurement (SBOP). WisDOT has delegated authority to purchase most commodities and services for any dollar amount. 

The State Bureau of Procurement has established competitive bidding as the preferred method of procurement for state of Wisconsin to ensure competition, fairness, impartiality and openness.
