Unified Facilities Criteria (UFC) documents provide planning, design, construction, sustainment, restoration, and modernization criteria.
UFC Documents also apply to the Military Departments, the Defense Agencies, and the DoD Field Activities in accordance with USD (AT&L) Memorandum dated 29 May 2002.
