CDOT Consultant Prequalification

Need Help?

Thank you for your interest in working with CDOT! CDOT has separate prequalification requirements for Professional Engineering Design Firms interested in doing business with CDOT.

Professional Engineering Consultants interested in providing design and engineering services for CDOT road and bridge construction projects must be prequalified. Sub-consultants must also be prequalified to provide professional services under an awarded contract.

The prequalification application must be completed online through the B2G system. To renew or start a new prequalification application, login to the B2G system with your existing account and or create a new account using the links provided below.

If your firm is interested in DBE or ESB Certification, please click here to start the certification process.

For questions regarding prequalification requirements, please contact Danielle Mire via email at danielle.mire@state.co.us or by phone at 303-757-9418.

If you require technical assistance while completing the form(s), please use our online support form.

It appears you have deactivated your alerts. This probably occurred when you clicked the checkbox that said "Prevent this page from creating additional dialogs".

Because the alerts have been disabled, your confirmation action cannot be captured and we cannot proceed with this process.

To clear this issue and get you on your way, it will be necessary to (1) log-off, (2) log back in, and (3) return to this process. In some cases, it may be necessary to completely close this Internet browser and other related windows after you logoff to fully clear the setting.

When presented in the future with an alert, please do not click the "Prevent this page from creating additional dialogs" checkbox, as the situation will repeat.

Thank you!
