Engineering, Architectural &
Professional Services
Prior to any road or bridge being constructed, the department identifies the need for specialized work in order to complete IDOT's Multi-Modal Multi-Year Transportation Improvement Program. To accomplish the program without appreciably increasing the number of IDOT personnel or performing services for which the department does not have specialized expertise, the department seeks out the services of professional engineering, land surveying and architectural firms.
In order to work for the department in this capacity, firms must first seek prequalification in specialized categories. Once prequalified a firm is eligible to submit a statement of interest on advertised projects. If selected, the firm follows department rules and regulations until fulfillment of the contractual obligation.
Prequalification
All engineering, land surveying and architectural consultants interested in providing services to IDOT, whether as a prime or subconsultant, must be prequalified with the department. IDOT prequalifies architectural/engineering consultants in multiple transportation categories of service. Prequalification is based on the firm’s and the individual’s professional experience and qualification. Annual updates to statements of experience and financial condition must be completed to maintain prequalification status. The process is governed by state Statute (30 ILCS 535/1).
There are approximately 400 firms prequalified with IDOT that are able to submit interest on engineering, land surveying and architectural project advertisements. Updated every Friday, the lists below provides the firm’s name, address, DBE status, contact person, phone number, fax number and prequalified IDOT category or categories. The lists posted are from the firms last approved Statement of Experience and Financial Condition. Firms with information in for review may have additional prequalification categories or may not have all the prequalification categories listed. Firms can track the progress of their Statement of Experience and Financial Condition review by viewing Status Column and the Category Column in EPAS.

To request an account:Email Jenni.LeSeure@illinois.gov. Indicate your firm’s interest in becoming a prequalified engineering consultant and attach the federal form, W-9.

Disadvantaged Business Enterprises (DBE) Goal
IDOT strives to maintain an equitable distribution of work for its many business partners. One way to accomplish this is through the department’s administration of the federally mandated DBE Program. The DBE program is intended to provide contracting opportunities to small businesses owned and controlled by socially and economically disadvantaged individuals. On most projects a DBE percentage goal is required.
To view the directory of DBE firms that are certified please view the IL UCP (updated every month).
Mentor Protégé ProgramThe Mentor Protégé Program is an IDOT program designed to enhance the capabilities of socially and economically disadvantaged businesses. The program centers on business collaborations between Mentor firms and Protégé firms which are socially and economically disadvantaged businesses certified as DBE. The program is designed to provide developmental assistance to enhance the Protégé’s business and technical capabilities to do more complex work. Navigate to Mentor Protégé Program to learn more.
