In a memo sent to me on Saturday, Nov. 1, 2025, from the District Dept. of Transportation (DDOT) concerning the United Certification Program (UCP) under which 3D Building Supplies LLC is approved as DBE, “UCP cannot decertify currently certified DBEs without completing the reevaluation process.” For further information, please see the details below that I have copied from the memo.

On October 3, 2025, the U.S. Department of Transportation (U.S. DOT) issued an interim final rule (IFR) requiring immediate changes to the Disadvantaged Business Enterprise (DBE) program regulations.
On October 24, 2025, The U.S. DOT published additional guidance on the IFR in the form of a set of Frequently Asked Questions (FAQs) related to the recent changes in the DBE program and the interim final rule (IFR). These FAQs can be found at the following link: https://www.transportation.gov/civil-rights/disadvantaged-business-enterprise/dbe-laws-policy-and-guidance.
The U.S. DOT’s FAQs state in section C, questions 2 and 3, that there is no date by which a Unified Certification Program (UCP) must complete its certification reevaluation process, and that a UCP cannot impose a deadline on currently certified DBEs for submission of the reevaluation documentation required under 49 CFR 26.111. Section C, question 4 states that a UCP cannot decertify currently certified DBEs without completing the reevaluation process.
