UFGS Master Updated May 16, 2017; Posted May 25, 2017

Unified Facilities Guide Specifications (UFGS) are a joint effort of the U.S. Army Corps of Engineers (USACE), the Naval Facilities Engineering 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 uses the latest CSI MasterFormat, therefore, as of January 2012, the UFGS Working Group decided to discontinue support of MasterFormat 1995. SpecsIntact version 4.5.1 and above will support MasterFormat 2010 and will no longer support the creation of Jobs or Masters using the old MasterFormat 1995 UFGS Master. For backward compatibility, Masters or Jobs created with older versions can still be opened using the latest software versions.

As of June 2008 :Updated UFGS will be posted quarterly in February, May, August and November.

As of May 2013: The May 2013 release incorporates Automatic Paragraph Numbering. Versions of Specsintact older than 4.5.0 are not compatible with this feature. Existing jobs can be converted to the new automatic numbered format. The conversion is a one-way process. To convert, select the job or master, select process menu, choose convert Job/Master to Automatic numbering. More information about Automatic Paragraph Numbering is available on the SpecsIntact website.

UFGS that have been unified for use by all participating agencies have a level 3 or level 4 MasterFormat™ number. UFGS that are agency-specific have a fifth level number indicating it as an agency specific specification. A specification that has a fifth level number "10" indicates USACE, a "20" indicates NAVFAC, a "30" indicates AFCEC, and a "40" indicates NASA. Preparing agencies are indicated in the UFGS header of each specification. The user should follow this order of precedence in selecting UFGS sections:

  1. Regional UFGS specific to their Agency
  2. UFGS identified as specific to their Agency
  3. Unified UFGS if one is available
  4. UFGS identified as specific to another DoD Agency (for DoD projects only)
  5. UFGS from another agency.

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

Section templates for MasterFormat 2010 and MasterFormat 1995: These templates are provided to assist the user in creating a new section.
