Back to definition list Subcontractor Registration IDOT is required to maintain a list of all contractors and subcontractors performing work on IDOT projects. Subcontractors interested in participating on IDOT contracts are required to register. Only registered subcontractors included in the list can be approved for IDOT projects. Prequalified contractors are automatically included in the list and are not required to register. Material suppliers and trucking companies are not included in the definition of subcontractor and are not required to register.
Subcontractors can register electronically by submitting the Subcontractor Registration Form.
The registration form requires minimal information and can be completed in minutes. Registration is valid for one year and will then require renewal. Call 217.782.3413 for more information. The objective is to facilitate communications by providing an electronic bulletin board for the contracting community. Subcontractors and suppliers have the ability to communicate their interest to prime contractors in providing quotes on a specific letting item and work category.
