Welcome to the Colorado Department of Transportation's centralized Professional Consultant Services Selection Process.

This site contains links for upcoming roadway design projects, documents needed to participate in the selection process, and consultant selection results.

Our goal is to obtain professional consultant services and provide for the timely completion and execution of all professional service contracts for the chief engineer's Office, and  to negotiate for the procurement of all engineering, architect, surveying and landscape architect contract services as provided for in Colorado Revised Statutes.

*Please note: to be a prime consultant on a contract, the prime consultant must provide at least 30 percent of the work itself.

Vendors and Contractors:
The Colorado Department of Transportation uses a vendor-facing portal. Benefits include:

  • enhanced ease of use to register and/or pre-qualify your organization to do business with CDOT;
  • elimination of reproduction and shipping costs by enabling direct electronic submittal of proposals for goods or services to CDOT; and
  • providing reporting visibility to track your POs and payments.

All vendors must be registered with CDOT, and most bidding/solicitation processes are performed through the vendor-facing portal, with the exception of highway construction bidding. Please check back regularly for updates and additional instructions.
