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.

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