Vendor Registration and Prequalification

CDB offers opportunities for firms to design, construct, and perform construction program management services on projects throughout the State of Illinois. Vendors must be prequalified prior to bidding or providing applications for selection. The processing of prequalification applications may take up to 45 days; therefore, firms are urged to prequalify now for upcoming projects associated with the Capital Bill.

IPG Mandatory with Prequalification

Please note: Prequalification and registration are not the same. If you are currently registered as a subcontractor but intend to submit a bid for a project as a prime contractor, or as a participant on a single prime project as a designated "protected subcontractor," then you must apply for prequalification approval.

There are three types of prequalification applications. Please download the form(s) applicable to the services you wish to bid on.

For assistance with prequalification, please email CDB.VendorReg@Illinois.gov

Note: Email attachments larger than 25 MB will be automatically removed from incoming emails. CDB does not receive notification that attachments have been removed, so please verify file size before submitting.

Subcontractor/Supplier

To participate on any CDB project as a subcontractor, supplier, or in any capacity you must have a CDB REGISTRATION NUMBER. If you are currently or have been prequalified with CDB, your firm has been assigned a registration number; therefore, you do not need to register with CDB. If you are a subcontractor, material supplier, or a consultant (who is not required to be prequalified), you must register.

Please note: Prequalification and registration are not the same. If you are currently registered as a subcontractor but intend to submit a bid for a project as a prime contractor, or as a participant on a single prime project as a designated "protected subcontractor," then you must apply for prequalification approval.

To inquire about an existing registration number, send an email to CDB.SubContractReg@illinois.gov

To apply for a new number, go to Vendor Registration.

Note: Email attachments larger than 25 MB will be automatically removed from incoming emails. CDB does not receive notification that attachments have been removed, so please verify file size before submitting.
