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 the 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/.

Hard copies of UFC printed from electronic media should be checked against the current electronic version prior to use to ensure that they are current.

CHAPTER 1 INTRODUCTION

1-1 SCOPE.

This UFC establishes fire protection engineering policy and criteria for Department of Defense (DOD) components. The provisions of this UFC are applicable to all new and existing DOD facilities located on or outside of DOD installations, whether acquired or leased, by appropriated or non-appropriated funds, or third party financed and constructed. Facilities covered by this document include all types of buildings and their contents, structures, whether considered temporary or permanent, mobile and stationary equipment, waterfront facilities, outside storage, and shore protection for ships and aircraft. Matters relating to fire department operations, staffing, and equipment are not covered by this UFC.

1-2 PURPOSE

The purpose of this UFC is to establish minimum protection requirements for DOD facilities. These criteria are based on commercial requirements set forth by national insurance underwriters and may exceed minimum national code requirements. The requirements in this UFC reflect the need for the protection of life, mission, and property (building or contents) while taking into account the costs of implementing the criterion and risks associated with the facility. These criteria have been established in the best interest of DOD.

1-2.1 Document Development

This document is intended to be used as a basis for the development of detailed design documents (including scope, basis of design, technical requirements, plans, drawings, specifications, cost estimates, request for proposals, and invitations for bids) used for the procurement of facilities, facility similar equipment, and other shore/land based infrastructure systems. It must be used as a reference document and requirement in the procurement of architectural and engineering services (A&E) and other consulting services to prepare detailed design documents including those for design/build projects. It is not intended to be used in lieu of detailed design documents in the procurement of facility construction.

1-3 CRITERIA

This UFC implements the following public laws:

a. UNITED STATES CODE http://www.gpoaccess.gov/uscode/index.html

b. USC Title 10, Section 1794 Military Child Care http://www.gpoaccess.gov/uscode/index.html

c. USC Title 15, Section 272 Utilization of Consensus Technical Standards by Federal Agencies

d. USC Title 15, Section 2225 Hotel-Motel Fire Safety

e. USC Title 15, Section 2227 Fire Administration Authorization Act (also referred to as the Fire Safety Act)

f. USC Title 15, Section 2225 Hotel-Motel Fire Safety

g. \1\ USC Title 49, Section 4151 Architectural Barriers Act of 1968 /1/

USC, Title 15, Section 272, identifies the necessary consensus technical standards required to implement policy objectives and activities within the area of fire protection engineering for the DOD. Compliance with criteria issued in accordance with this UFC does not constitute an exception to the public laws.

Fire protection criteria must conform to the requirements of this UFC, the \1\ latest editions of the /1/ National Fire Codes, published by the National Fire Protection Association (NFPA), except as modified by this UFC, and \2\ UFC 1- 200-01, General Building Requirements. /2/ Additional criteria include portions of the \1\ latest edition of the FM Global (Property Loss Prevention Data Sheets, /1/ as referenced by this UFC. Buildings required to be accessible must meet the provisions \2\ of Americans with Disabilities Act and Architectural Barriers Act Accessibility Guidelines, ABA Chapters 1 & 2 and general Chapters 3 through

10. /2/ Note 1: UFC 1-200-01 identifies the base line building code as the International Building Code to be used for all DoD construction. NFPA 5000 Building Construction and Safety Code, State or Local building codes will not be used.

Note 2: Projects that have significant time delays between the award for design and the beginning of construction must be re-evaluated and corrected to comply with any new editions of criteria (including codes and standards) that have been published.

1-3.1 Existing Facilities.

Existing facilities must meet the requirements of NFPA 101, Life Safety Code, for existing occupancies.

Facilities that do not meet the requirements of NFPA 101 for existing facilities must be brought up to, at least the minimum requirements for existing facilities. If the facility cannot be brought up to the minimum requirements for existing facilities without initiating a renovation, modernization, or rehabilitation project, that project must meet the requirements for new construction as specified in this

UFC.

Any changes in occupancy require the facility to meet the requirements for new construction for the new occupancy as specified in this UFC.

1-3.2 Application/Types of Work Efforts.

This UFC applies to all work necessary to build, maintain, or change DoD facilities/structures/systems. The services and agencies within DoD use various terms to classify these work efforts.

1-3.2.1 Construction.

Construction projects provide new facilities/structures/systems and must comply with the criteria in this UFC. Additions to existing buildings must comply with the criteria for new buildings. \2\ Additions greater than 50% of the existing building's gross floor area shall require the existing building comply with the criteria for new buildings, to the maximum extent possible. Multiple additions which cumulatively increase the original building footprint by more than 50% shall require the existing building to comply with the criteria for new buildings, to the maximum extent possible. /2/

1-3.2.2 Modernization/Major Investments.

Buildings that have alteration, modernization, modification, rehabilitation, and renovation costs equal to or exceeding 50% of the replacement cost of the building, must bring the entire building into compliance with new construction requirements. \2\ Phased projects shall be considered based on the cumulative total costs of all phases. The 50% cost value is exclusive of the costs to bring the building into full compliance. /2/

Facilities in which alteration, modernization, rehabilitation, and renovation work is less than 50% of the replacement value of the building, the building must comply with the criteria in this UFC for new construction, to the maximum extent practical. All new work accomplished as part of alteration, modernization, modification, rehabilitation, and renovation actions/projects must meet the requirements for new construction.

1-3.2.3 Sustainment and Restoration.

New work accomplished in facilities as part of repair, restoration, and sustainment actions/projects must meet the requirements for new construction in this UFC.

Note: Sustainment and restoration efforts should look beyond the scope of work to ensure that the fire protection (including life safety) features are not being compromised or designed only for the portion of the building that is being repaired. The repair project, if possible, should include a basis to support the entire building, i.e., if considering providing a fire alarm extender panel to the existing antiquated fire alarm control panel, ensure the panel being provided has the capability to support the entire building so any additional projects can utilize the new panel without having to remove what was just installed.

1-3.2.4 Conversion of Use/Change of Occupancy.

When any portion of an uninhabited building is modified from its current use to that of an inhabited building, billeting, or a primary gathering building, as defined by UFC 4-010-01, DoD Minimum Antiterrorism Standards for Buildings, for one year or more, the building must meet the requirements for new construction.

Note: Examples would include a warehouse (uninhabited) being converted to administrative (inhabited) use; an inhabited administrative building being converted to a primary gathering building or billeting; or a non-compliant primary gathering building/billeting being altered, modernized, modified, rehabilitated, or renovated and converted to billeting/primary gathering building. Definitions of inhabited, uninhabited, primary gather building and billeting are found in UFC 4- 010-01.

1-3.2.4.1 When any portion of a building is modified from its current use to that of a mission essential building for one year or more, the building must meet the requirements for new construction.

Note: Examples would include a warehouse being converted to an aircraft hangar.

1-3.2.4.1 When any portion of a building is modified from its current use to any other occupancy use for two years or more, the building must meet the requirements for new construction. Changing groups of occupants within the occupancy classification does not constitute an occupancy change.

Note: An example of modifying from one occupancy to another would include an office building converted to mercantile. An example of changing groups of occupants would include an installation personnel function occupying the office space formally used by an installation contracting function.

1-3.3 Absence of Criteria

When a specific application is not covered by the criteria cited in this UFC, follow national building codes, recognized industry standards, and standard engineering practices. In the absence of such technical information, contact the DOD component authority having jurisdiction (refer to the paragraph entitled “Authority Having Jurisdiction (AHJ)”).

1-3.4 Performance-Based Fire Safety Design.

It is permissible that performance-based fire safety design methods be applied to the renovation, restoration, remodeling or modernization of existing facilities to address the evaluation of a subsystem, system, or complete building when it is not possible to meet the provided prescriptive requirements for new construction.

New facilities for which established prescriptive criteria exist, must not be permitted to use performance-based fire and life safety design methods. The use of performance-based fire safety design methods must only be permitted upon authorization by the DOD component authority having jurisdiction (AHJ) for new mission critical or unique facilities, where the user mandates requirements and objectives that are not addressed by established prescriptive requirements of national codes or this UFC. Performance-based fire safety design methods must not be used to eliminate required exiting requirements of NFPA 101, nor must it be used to eliminate automatic sprinkler systems required by DOD criteria.

1-3.4.1 Application and Use of Performance-Based Fire Safety Design Methods.

If performance-based fire safety design is used or permitted by the DOD component AHJ, Appendix D describes the provisions and applicable requirements associated with the fire safety design of DOD facilities. Appendix D is in accordance with the performance-based option of NFPA 101, Life Safety Code, and the performance-based fire safety design approach of the Society of Fire Protection Engineers (SFPE), Introduction to Performance-Base Fire Safety.

A fire protection engineer that meets the requirements of the paragraph entitled, “Fire Protection During Construction“ below must perform the performance-based fire safety design.

1-3.5 Conflicts in Criteria.
