Provide fabric continuous between terminal posts; however, runs between terminal posts shall not exceed 500 feet. Repair any damage to galvanized surfaces, including welding, with paint containing zinc dust in accordance with ASTM A780/A780M.

3.1.2 Excavation

Clear all post holes of loose material. Spread waste material where directed. Eliminate ground surface irregularities along the fence line to the extent necessary to maintain a 2 inch clearance between the bottom of the fabric and finish grade.

3.1.3 Concrete Slabs and Walls

Set posts into zinc-coated sleeves, set in concrete slab or wall, to a minimum depth of 12 inches. Fill sleeve joint with lead, nonshrink grout, or other approved material. Set posts for support of removable fence sections into sleeves that provide a tight sliding joint and hold posts aligned and plumb without use of lead or setting material.

3.2 POST INSTALLATION

3.2.1 Earth and Bedrock

a. Set posts plumb and in alignment. Except where solid rock is encountered, set posts in concrete to the depth indicated on the drawings. Where solid rock is encountered with no overburden, set posts to a minimum depth of 18 inches in rock. Where solid rock is

Section 32 31 13.53 Page 8 covered with an overburden of soil or loose rock, set posts to the minimum depth indicated on the drawing unless a penetration of 18 inches in solid rock is achieved before reaching the indicated depth, in which case terminate depth of penetration. Grout all portions of posts set in rock.

b. Portions of posts not set in rock shall be set in concrete from the rock to ground level. Posts set in concrete shall be set in holes not less than the diameter required. Make diameters of holes in solid rock at least 1 inch greater than the largest cross section of the post.

Thoroughly consolidate concrete and grout around each post, free of voids and finished to form a dome. Allow concrete and grout to cure for 72 hours prior to attachment of any item to the posts. Group II line posts may be mechanically driven, for temporary fence construction only, if rock is not encountered. Set driven posts to a minimum depth of 3 feet and protect with drive caps when setting.

Test fence post rigidity by applying a 50 pound force on the post, perpendicular to the fabric, at 5 feet above ground. Post movement measured at the point where the force is applied shall be less than or equal to 3/4 inch from the relaxed position. Test every tenth post for rigidity. When a post fails this test, make further tests on the next four posts on either side of the failed post. All failed posts shall be removed, replaced, and retested at the Contractor's expense.

3.2.2 Concrete Slabs and Walls

Set posts into zinc-coated sleeves, set in concrete slab or wall, to a minimum depth of 12 inches. Fill sleeve joint with lead, nonshrink grout, or other approved material.

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:

Unified Facilities Criteria (UFC) New Document Summary Sheet

Document: UFC 4-022-03, Security Fences and Gates.

Superseding: NAVFAC Military Handbook 1013/10, Design Guidelines for Security Fencing, Gates, Barriers, and Guard Facilities.

Document Description and Need:

Purpose: This document is to provide a unified approach for the design, selection, and installation of security fences and gates. The examples provided in the UFC are for illustration only and must be modified and adapted to satisfy service and installation specific constraints. This document is not intended to address procedural issues such as threat level determination and security operations or to provide specific design criteria such as impact forces.

This UFC was developed by consolidating and refining criteria from USACE Protective Design Center, Naval Facilities Engineering Command (NAVFACENGCOM), and available military, government, and commercial sources that are listed in Appendix A of this document.

Application and Use: Commanders, security personnel, planners, designers, architects, and engineers must use this UFC when evaluating existing and providing new security fences and gates.

Need: Fences and gates are primarily used to define perimeters; however, Department of Defense (DoD) and Service regulations require fencing to be provided for certain protected/restricted areas. DoD and Service policies address certain fencing requirements. This UFC focuses on the requirements for security fences, however, the information and design details presented within may also be used for general or perimeter fencing. Modifications to existing fencing are not required to meet this new

UFC.

Impact: The following direct benefits will result:

• This document does not set the requirement for security operations at the installation perimeter.

• No additional cost impacts are anticipated by the publication of this document.

• This document does not have any adverse impacts on environmental, sustainability, or constructability policies or practices.

Unification Issues There are no unification issues.

1-5 GENERAL BUILDING REQUIREMENTS

Comply with UFC 1-200-01, General Building Requirements. UFC 1-200-01 provides applicability of model building codes and government unique criteria for typical design disciplines and building systems, as well as for accessibility, antiterrorism, security, high performance and sustainability requirements, and safety. Use this UFC in addition to UFC 1-200-01 and the UFCs and government criteria referenced therein.

This UFC is one of a series of unified facilities criteria documents that cover minimum standards, planning, preliminary design, and detailed design for security and antiterrorism. The manuals in this series are designed to be used by a diverse audience to facilitate development of projects throughout the design cycle.

1-5.1 UFC Application

The application of the security and antiterrorism UFCs is illustrated in Figure 1-1. UFC 4-020-01 is intended to be the starting point for any project that is likely to have security or antiterrorism requirements. By beginning with UFC 4-020-01, DoD Security Engineering Facilities Planning Manual, the design criteria will be developed that establishes which of the other UFCs in the series will need to be applied. The design criteria may indicate that only the minimum standards need to be incorporated, or it may include additional requirements, resulting in the need for application of additional UFCs.

Applying this series of UFCs in the manner illustrated in Figure 1-1 will result in the most efficient use of resources for protecting assets against security and antiterrorism related threats.

1-5.2 Requirements Determination

UFC 4-020-01 includes a process for defining the design criteria for a protective system that protects important assets associated with a permanent facility or one in an expeditionary environment. The design criteria will consist of the assets to be protected, the threats to those assets, the degree to which those assets will be protected against the threat, and any constraints that might be imposed on a design.

The design criteria may be limited to that defined in minimum standards or it may go beyond those requirements.

Establishing the design criteria for security and antiterrorism is not something that can be done effectively by any one person. It requires a team of people to ensure that the varied interests relating to a project are considered appropriately. The specific membership of a planning team will be based on local considerations, but in general, the following functions should be represented - Facility User, Antiterrorism, Intelligence, Operations, Security, Logistics, Engineering, and Resource Management. Based on local considerations, there may be others who should be consulted for input into the design criteria. They might include Fire Marshals, communications people, environmental people, and historic preservation officers.

1-5.3 Integration With Other Requirements

Security and antiterrorism requirements will never be the only requirements associated with a project. Even where a project is specifically for security and antiterrorism upgrades, there will still be other requirements that must be considered. There will be times where one criterion is more stringent than another, in which case the more stringent one must be applied. In some cases, criteria may conflict. In those cases, those conflicts must be resolved, which may require compromise or adjustment to one or the other criteria. Many security regulations specify protective measures, policies, and operations related to security. This UFC is intended to complement those existing regulations, not to contradict or supersede them. Regulatory requirements must be accommodated and coordinated.

Figure 1-1 Security and Antiterrorism UFC Application

1-6 VULNERABILITY AND RISK ASSESSMENT

In accordance with DoD O-2000.12H Antiterrorism Handbook, a vulnerability and risk assessment must be conducted prior to beginning any security project. Upon identifying facility or asset vulnerabilities to threats, physical security measures such as security fences, gates, and Electronic Security Systems (ESS) may be deployed to reduce vulnerabilities. In summary, this UFC assumes the pre-design phases, including the risk analysis, are complete prior to beginning design. For information on Security

Engineering Planning and Design process, refer to UFC 4-020-01 and UFC 4-020-02.

The engineering risk analysis conducted as part of UFC 4-020-01 must be consistent with the terrorism risk analysis conducted by the installation security/AT staff.

As such, the installation AT plan reflects the foundation for requirements determination. Installation specific requirements need to be factored into all capital improvement initiatives.

1-7.5 Airfield Requirements

For Air National Guard (ANG) and Air Force Reserve Command (AFRC) units that are co-located with civilian airports, the airfield side of the restricted areas does not require fencing installation as it is prohibited by the Federal Aviation Agency (FAA) safety requirements. Fencing requirements for airports and heliports are provided in UFC 4- 141-10N and UFC 3-260-01.

1-8 PHYSICAL SECURITY

That part of security concerned with physical measures designed to safeguard personnel; to prevent or delay unauthorized access to equipment, installations, material, and documents; and to safeguard them against espionage, sabotage, damage, and theft.

1-8.1 Physical Security System

A system comprised of people, equipment, and operational procedures that control access to critical facilities or assets. Fences are but one of many elements that comprise the equipment component of a physical security system. Figure 1-2 diagrams some of the additional components of a physical security system.

From Figure 1-2, fencing is considered part of the delay function of the overall Physical Security System. However, standard chain-link fencing provides approximately 7- 15 seconds of delay.

Figure 1-2 Diagram of Physical Security System Functions

1-9 EMERGENCY ACCESS

Locate security fence as to not impede emergency vehicle or emergency personnel access to fire hydrants or other fire protection features. Coordinate with installation fire department regarding security fence location as it applies to fire hydrants and other fire protection features. See UFC 3-600-01, Fire Protection Engineering for Facilities for additional information.

1-10 CORROSION PREVENTION CONTROL

Design strategies for installation security structures and equipment must consider corrosion prevention and control (CPC) preservation techniques for long term maintainability throughout their life cycle. Trade-off decisions involving cost, useful service life, and effectiveness must address corrosion prevention and mitigation.

1-10.1 Material Selection and Coatings

Local environments must be considered during the selection of material for the fencing components as well as the required coatings to provide protection against corrosion.

Color polymer and other coatings on fencing fabric, fittings, framework, and gates must be applied to enhance visibility and provide greater corrosion resistance, especially in corrosive or salt laden environment. Appendix B defines this environment.

Coating on any fasteners or ties must be electrolytically compatible with fencing fabric to inhibit corrosion. All security fence fittings must be electrolytically compatible with all fence components. Regarding drainage openings (ditches, culverts, vents, metal ducts/pipes, and other opening) consideration must be given to the materials used (smaller metal pipe, metal/steel grillage) in securing such openings. One of the most important corrosion issues is the chemical reaction between dissimilar metals. When dissimilar metals are in contact with one another in the presence of an electrolyte, galvanic action occurs, resulting in the deterioration. The electrolyte may be rain water running from one surface to another, or moisture from the air containing enough acid to cause it to act as an electrolyte. See Appendix A for material specifications.

CHAPTER 2 FENCING

2-1 FUNCTION

The physical security barrier provided by a security fence provides one or more of the following functions:

• Gives notice of legal boundary of the outermost limits of the protected area.

• Assists in controlling and screening authorized entries into secured/protected areas by channeling vehicles and personnel to access control points.

• Supports surveillance, detection, assessment, and other security functions by providing a platform for installing intrusion detection equipment.

• Deters casual intruders from penetrating a secured/protected area by presenting a barrier that requires an overt action to enter.

• Causes a delay to obtain access to a installation/facility, thereby increasing the probability of detection.

2-2 CHAIN LINK FENCING

Chain link fence is a fencing material made from wire helically wound and interwoven in such a manner as to provide a continuous mesh without knots or ties. See Figure 2-1 below for standard chain link fence details identifying all of the components.

Chain link fences and gates must comply with specification requirements in UFGS 32 31 13, Chain Link Fences and Gates and UFGS 32 31 13.53, High-Security Chain Link Fences and Gates. Consult with ASTM F2611 and ASTM F1712 for additional guidance (fabric, post, framework, fittings, and other accessories) regarding chain link fencing. Refer also to the Chain Link Manufacturers Institute’s Security Fencing Recommendations (CLF-SFR0111) and Product Manual (CLF0PM0610) for additional information.

2-2.1 Chain Link Fencing Fabric

Fencing fabric must be minimum 9-gage wire mesh and mesh openings must be not be greater than 2-inches (51 mm) per side. Fence fabric material will be galvanized steel, PVC coated steel fabric (use PVC coated if located in corrosive environment or where aesthetics are of prime importance), or aluminum coated steel fabric (use aluminum coated if located in corrosive environment). See Corrosion Prevention Control for additional information regarding material selection.

2-2.1.1 Additional Fencing Fabric Requirements

The fencing fabric must be extended to within 2 inches (51 mm) of firm ground and anchored, if required by service requirements, using horizontal bottom rails, tension wires, concrete curbs, sills, sheet piling, piping, or other inexpensive materials. For additional security burying the fabric 12 inches (305 mm) may also be considered;

however, corrosion of the buried fabric must be monitored. This anchoring will prevent the fencing fabric from being able to be lifted by hand more than 5 inches (125 mm) in height. Horizontal bottom rails, concrete curbs, or sills can assist in mitigating an intruder from lifting the fence fabric beyond the requirement above. Mesh openings in chain link fencing are intended to not be covered, blocked, or laced with material which would prevent a clear view of personnel, vehicles, or material in outer clear zones.

Locate all posts, rails, bracing and tension wires on the secure/protected side, i.e. inner side, of the fencing fabric. Select the framework components and material from ASTM F626, ASTM F1043, and ASTM F1083.
