Firms looking for prime contracts in construction and design engineering must first register with the Department. The registration process culminates in a firm's inclusion on the Roster of Eligible Engineering Consultants. There is a biennial renewal process for all firms on the Roster, but new firms may register at any time.

Specialty services

​Firms looking for opportunities to perform specialized non-engineering services such as survey, landscape architecture, historical and environmental investigations are not required to register with the Department. However, these firms may need to complete a Consultant financial report to establish an indirect cost rate.

WisDOT usually advertises master contracts for those services, rather than soliciting for interest on individual projects. Master contracts are used on an as-needed basis by WisDOT for a given period of time.

Disadvantaged Business Enterprises

Information about registering as a Disadvantaged Business Enterprise (DBE)​​ is maintained by the Office of Business Opportunity and Equity Compliance (OBOEC).​


Firms looking for subconsultant opportunities are not required to apply for the Roster of Eligible Engineering Consultants.

WisDOT does not make prime-sub connections, but WisDOT approves the uses of any subconsultants.

The Roster of Eligible Engineering Consultants includes addresses and other information about all firms registered for prime work for WisDOT.

Qualifications based selection

Consultant contract selections are made using a Qualification-Based Selection process, per the federal Brooks Act. But because there are often 10 or more well-qualified firms applying for projects, even companies providing quality work to WisDOT in the past cannot be awarded every contract in which they express interest.

Although WisDOT uses communication tools like the Internet and email to make consultants aware of upcoming opportunities, it is your firm's responsibility to be cognizant of Internet solicitations and up-to-date on Department policies and procedures.
