NAICS Code Change Requests

CDOT only certifies firms for specific types of work that the disadvantaged owners have the ability to control. CDOT uses the most specific North American Industry Classification System (NAICS) code and index descriptor available to describe each type of work performed by the DBE.

Certified DBE firms may request work code changes or additions by submitting a Work Code Change Request (CDOT Form #1311). CDOT will verify that the disadvantaged owner has the ability to control the work, that the firm is actually engaged in the requested work, and that it has the resources necessary to perform the work.

See the Colorado UCP Work Code Map (Excel document) for a list of NAICS work codes.
