The actual construction of projects identified in IDOT's Multi-Modal Multi-Year Transportation Improvement Program is outside of IDOT's scope of work. IDOT utilizes outside contractors to fulfill this role. The department is committed to maintain the state’s highway system through a successful business venture with the contractor community.
In order to work for IDOT in this capacity, contractors must first seek prequalification in specialized categories. Once prequalified, a firm is eligible to submit a bid on state and locally advertised projects. If awarded the contract, the firm follows department rules and regulations until fulfillment of the contractual obligation.
Any firm interested in bidding on construction projects for IDOT, local entities, and/or Department of Natural Resources (DNR) as a prime contractor must first be prequalified. The prequalification process is governed by Title 44 Illinois Administrative Code Section 650. There are approximately 750 firms currently prequalified to bid on state highway and locally advertised projects in Illinois. Updated every Monday, the List of Prequalified Firms (Text File | Excel File) provides the name, address, phone, fax numbers and the numerical work categories for which each firm is prequalified.
Outlined below is information on prequalification, human rights, renewal, and revising or adding prequalification categories:
Prequalification grants a firm permission to bid on construction contracts, including local agency projects. Moreover, a prequalified prime is automatically classified as a registered subcontractor. The steps to gain prequalification status are outlined below:
Once IDOT determines the applicant is responsible and prequalification ratings are calculated, a "Certificate of Eligibility” will be issued and the firm name will be added to the List of Prequalified Firms (Text File | Excel File). If the department is unable to establish prequalification ratings, the applicant will be notified in writing.

Subcontractors will be required to register with the department before being approved to work on projects. Prequalified contractors are automatically included in the list and are NOT required to register. Material suppliers, trucking companies, and companies providing professional services (consultants) are NOT included in this definition of subcontractor and are not required to register.
Updated every Monday, the List of Registered Subcontractors (Text File), provides their registration number, name, address, phone, fax numbers.
This section of the website is designed to outline the role and responsibilities of subcontractors as it relates to IDOT projects. Subcontractor information can be found below, please click each item to expand.

If a subcontractor does not have a valid email address, a notice will be sent via postal mail. Subcontractors can renew their registration on line via the Subcontractor Registration Update Form.

The Transportation Bulletin details the projects being advertised. Subcontractors must deal directly with the prime contractors that are authorized to bid on a project. There are two ways to communicate with the prime contractor to express interest.
Once a contract is awarded, IDOT interacts with the prime and the prime alone. In order to further clarify roles and increase understanding of the process, the following is provided as information.
A subcontractor cannot be approved or begin work until all the documents have been received and approved. These requirements do not apply to material suppliers, truckers and professional service companies.
It is the responsibility of subcontractors and suppliers on IDOT highway construction projects to collect monies that are owed to them by the prime contractor. IDOT is unable to make payments to anyone other than the prime contractor, so you must protect yourself from nonpayment or collection problems.
Navigate to Lien and Bond Claims for more information.
Subcontractors are required to follow the specs, policies, and manuals to complete the work.
Bids for state work are only accepted by authorized prequalified prime contractors. If you are not a prequalified prime contractor, but are interested in becoming prequalified, please navigate to the Prequalification tab.
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.

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).

All state and federally funded jobs have certain board requirements that must be posted at the beginning and until the finalizing stages of the project. All prime contractors for every contract let are required to have these posted. They are posted on/adjacent/and at a visible site at all hours of the contract.
Recent changes have been made to the state and federal board requirements. Changes to these requirements can occur frequently due to compliance with regulations and the Department of Labor (DOL). The requirements (links for each poster) are posted on the IDOT website under Doing Business. The information we used to update our bulletin board requirements was found on the IDOL website.
Construction Memorandum No. 6-24 is the Equal Employment Opportunity (EEO) Contract Provisions and District Responsibilities memo. All district EEO as well as IDOT staff use this memorandum adjacent to the IDOL requirements to meet board requirements as well to collect and keep update all information.
