UFGS Master Updated February 13, 2024; Posted February 22, 2024

Unified Facilities Guide Specifications (UFGS) are a joint effort of the U.S. Army Corps of Engineers (USACE), the Naval Facilities Engineering Systems Command (NAVFAC), and the Air Force Civil Engineer Center (HQ AFCEC). UFGS are for use in specifying construction for the military services.

On September 30, 2023, NASA officially withdrew from the UFGS program. All NASA-specific UFGS sections (40) have been removed from the UFGS Master, though some UFGS sections may still include a NASA section reference. The final NASA UFGS Master is available on the WBDG at NASA UFGS Master Specifications.

The Unified Facilities Guide Specifications (UFGS) are published only in electronic format and are intended to be used with SpecsIntact software. The UFGS Master complies with UFC 1-300-02. SpecsIntact supports the UFGS format. SpecsIntact can still open Masters or Jobs created with older versions of the UFGS format.

Updated UFGS are posted quarterly in February, May, August, and November.

UFGS that have been unified for use by all participating agencies have a level 3 or level 4 Section number. The UFGS uses level 5 to identify a single-agency specification. The number "10" is used by USACE, "20" by NAVFAC, and "30" by AFCEC. The order of precedence for selecting UFGS sections for a project is generally:

  1. Regional UFGS if required by the contract or published on WBDG
  2. Single-agency UFGS for whom project is being developed
  3. Unified UFGS
  4. UFGS identified as specific to another DoD Service (for DoD projects only)

Points of contact and procedures for the development and maintenance of UFGS documents are prescribed in the latest edition of MIL-STD-3007.

The UFGS Section Template is now provided in the UFGS Master with each quarterly release and can be found under Tools in the SpecsIntact Explorer.

Questions, comments, suggestions and recommended changes for guide specifications should be submitted as a Criteria Change Request (CCR). To submit, click on the CCR link next to the document title (below). CCRs are not appropriate when they pertain to a specific project solicitation, request for proposal, or after a project award. Questions or interpretations pertaining to these documents or situations should be referred to the Contracting Officer.
