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.

NEW DOCUMENT SUMMARY SHEET

Document: UFC 4-211-01, Aircraft Maintenance Hangars
Superseding: UFC 4-211-01N, Aircraft Maintenance Hangars: Type I, Type II and
Type III dated 25 October 2004 with Change 3 dated 16 December 2009, NAVFAC
Interim Technical Guidance (ITG 2010-01) - Maintenance Hangar Design and Planning
Guidance for F35B or C, and Engineering Technical Letter (ETL) 02-15: Fire Protection
Engineering Criteria New Aircraft Facilities, 3 December 2002.
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 Services 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.
