UFGS Master Updated May 11, 2023; Posted May 25, 2023

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), the Air Force Civil Engineer Center (HQ AFCEC) and the National Aeronautics and Space Administration (NASA). UFGS are for use in specifying construction for the military services.

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, "30" by AFCEC, and "40" by NASA. 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 are welcome and should be submitted as a Criteria Change Request (CCR). To submit a Criteria Change Request, click on the CCR link next to the document below. If a CCR does not fit cleanly into an existing section, submit a CCR to the section most closely related to the CCR. 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 situation should be referred to the Contracting Officer.

Click the 'Title' or 'Date' heading to sort by ascending or descending order. Narrow the list by selecting a 'Division' option from the drop-down or view archived documents by selecting from the 'Status' drop-down and clicking 'Apply'.
