Register & Prequalify in B2G

Contractor Registration

CDOT requires all contractors to be Registered in B2G before performing work on CDOT projects. Registration provides the agency with data and information that is both required for reporting and useful for better understanding our contracting community composition. 

Please note that creating an account in B2G does not mean you are Registered; visit Contractor Registration/Prequalification in the left navigation pane to complete the Registration Form.

Prime Contractor Prequalification

Contractors that intend to bid as a Prime Contractor must be prequalified. Prequalification ensures financial and managerial capacity to oversee a CDOT project.
