What does an availability analysis mean? CDOT will only restrict projects if there are available ESB firms. An availability analysis is conducted on each project to ensure there are ample firms who are ready, willing, and able to bid on the work.

Prime Contracting for ESBs

  • Prequalification. You must be prequalified to bid on these projects. Please visit and click Register & Prequalify to begin the process. If you have questions or need assistance with prequalification contact Marci Gray at 303-757-9297 or [email protected]

  • Bidding Software. You must bid for the project through a software called Bid Express. An ESB must subscribe to Bid Express if they intend to bid on an ESB restricted project. To ensure that this is not a barrier for the upcoming restricted project, we have allocated money to reimburse firms for the cost of a one-month basic subscription plus the one-time fee for the digital ID  for an upcoming ESB restricted project if the ESB bids on the project. The ESB firm may then choose to continue to pay the monthly subscription fee on their own or cancel the account after the ESB bid is final. A digital ID is reimbursable by CDOT up to one time each year. To request reimbursement, qualifying firms must submit the following to Debra Lancaster ([email protected] ) within 60 days of the firm's bid:
