UFGS Master Updated February 12, 2025; Posted February 20, 2025

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.

The UFGS are only published in electronic format and are intended to be used with SpecsIntact software; SpecsIntact supports the UFGS format. The UFGS Master complies with UFC 1-300-02.

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. To view the UFGS modification classifications and examples, see the UFGS Revision-Change Policy .

Active documents are available in the following formats:  SpecsIntact (SEC) in compressed ZIP  |  Adobe Acrobat (PDF)

Archived release files are available in Adobe Acrobat (PDF) in compressed ZIP
