Get Connected With CDOT Opportunities

Connect2DOT is now offering a Bid Matching Service (BMS) that will inform you of CDOT highway construction project opportunities that match the type of work you perform. Below is a list of NAICS Codes that are used frequently on CDOT construction projects. Please select the NAICS codes you are interested in hearing about, and you will receive a weekly email any time CDOT advertises a new project with bid items that match the work categories you select. 

If your NAICS code is not in the list, the BMS may not be for you. For example, CDOT design/consultant projects are not included. Please visit Project Opportunities for links to CDOT's current construction and consultant project advertisements, as well as other bidding resources.
