UFC 4-211-01 13 April 2017 FOREWORD The Unified Facilities Criteria (UFC) system is prescribed by MIL-STD 3007 and provides planning, design, construction, sustainment, restoration, and modernization criteria, and applies to the Military Departments, the Defense Agencies, and the DoD Field Activities in accordance with USD (AT&L) Memorandum dated 29 May 2002. UFC will be used for all DoD projects and work for other customers where appropriate. All construction outside of the United States is also governed by Status of Forces Agreements (SOFA), Host Nation Funded Construction Agreements (HNFA), and in some instances, Bilateral Infrastructure Agreements (BIA.) Therefore, the acquisition team must ensure compliance with the most stringent of the UFC, the SOFA, the HNFA, and the BIA, as applicable. UFC are living documents and will be periodically reviewed, updated, and made available to users as part of the Services’ responsibility for providing technical criteria for military construction. Headquarters, U.S. Army Corps of Engineers (HQUSACE), Naval Facilities Engineering Command (NAVFAC), and Air Force Civil Engineer Center (AFCEC) are responsible for administration of the UFC system. Defense agencies should contact the preparing service for document interpretation and improvements. Technical content of UFC is the responsibility of the cognizant DoD working group. Recommended changes with supporting rationale should be sent to the respective service proponent office by the following electronic form: Criteria Change Request. The form is also accessible from the Internet sites listed below. UFC are effective upon issuance and are distributed only in electronic media from the following source: • Whole Building Design Guide web site http://dod.wbdg.org/. Refer to UFC 1-200-01, DoD Building Code (General Building Requirements), for implementation of new issuances on projects. AUTHORIZED BY: LARRY D. McCALLISTER, PhD, PE, JOSEPH E. GOTT, P.E.

Description: This UFC provides criteria for planning and design of Aircraft Maintenance Hangars for the aircraft of the combined DoD United States Armed Forces. Reasons for Document: This is a new Joint Service document. This new document represents another step in the Joint Services effort to bring uniformity to the planning, design and construction of military facilities. The UFC was developed to provide design requirements to accomplish the following: • Assist planners in understanding the facility requirements to ensure accurate space programs budgets. • Provide architects, engineers, and construction surveillance personnel with essential, minimum (min) requirements for the design and construction of Aircraft Maintenance Hangars. • Clarify the operational intent of the facility design. Impact: The following will result from the publication of this UFC: • This UFC creates a single source for common DoD Aircraft Maintenance Hangar criteria and an accurate reference to individual Service-specific documents. • This UFC facilitates updates and revisions and promotes agreement and uniformity of design and construction between the Services. Unification Issues: Non-unified content is mainly a result of operational differences among the ServicesCANCELLED and is addressed in the Service-specific chapters including: • The Navy included Functional Data Sheets (FDS) in this UFC. The Army keeps their Room Data Sheets with the Army Standard and the Air Force keeps these specific requirements with their Dynamic Prototypes. • The Army and Navy perform fuel cell operations in the Aircraft Maintenance Bay per operational guidelines. The Air Force has specific construction criteria for the design of fuel cell maintenance hangars.
