3.6 FABRIC INSTALLATION

A. Provide Fabric in single lengths between stretch bars placed so that the bottom of the fabric is a nominal distance of 2" above the ground line;

however, over irregular ground this distance may vary between 1" and 6" for a distance not to exceed 8'. Then the clearance exceeds 4", the fabric shall be attached by tie wire to metal stakes driven 18" into the ground. Stakes to be 24" long and spaced 24" on center and shall be furnished at no additional cost to the Government.

B. The contractor shall install and pull taut to provide a smooth and uniform appearance free from sag, without permanently distorting the fabric diamond or reducing the fabric height. Pull fabric taut and tied to posts, rails, and tension wire with wire ties and bands. Fasten fabric to line posts at approximately 15” intervals and fastened to all rails and tension wires at approximately 15” intervals. Fabric must remain under tension after the pulling force is released.

C. After the fabric installation is complete, exercise the fabric by applying a 50 lb push-pull force at the center of the fabric between posts; the use of a 30 lb pull at the center of the panel shall cause fabric deflection of not more than 2.5” when pulling fabric from the post side of the fence; every second fence panel shall meet this requirement.

D. Install fabric on the security side of fence, unless otherwise directed.

E. Provide fabric continuous between terminal posts; however, runs between terminal posts shall not exceed 500'.

3.7 BARBED WIRE AND SUPPORT ARM INSTALLATION

A. Install barbed wire supporting arms and barbed wire as indicated on the drawings and as recommended by the manufacturer. Anchor supporting arms to the posts in a manner to prevent easy removal with hand tools. Pull barbed wire taut and attach to the arms with clips or other means that will prevent easy removal. Barbed wire shall be securely fastened at gate posts, corner posts, and pull posts. All barbed wire shall be stretched and permanently secured to a tension that will not deflect more than 2 inches when a pull of 20 pounds is applied in the center of the span.

Facilities Management 32 31 13 - 9

3.8 STRETCHER BAR INSTALLATION

A. Thread stretcher bars through or clamped to fabric 4 inches on center and secured to posts with metal bands spaced 15 inches on center.

3.9 GATE INSTALLATION

A. Gate to be set at 3” maximum clearance from ground or concrete or over curb. Top of gate sections and barbed wire to be straight, plum, square, and level

B. Gate shall allow full clearance for drive. Gates shall roll smoothly and easily to be completely clear of the drive when retracted and shall have stops on each end to prevent passing rollers. Cantilever shall have clearance of 3 to 5 inches. Gate shall have a device for locking when closed to secure yard.

3.10 TIE WIRES

A. Provide tie wires that are U-shaped to the pipe diameters to which attached.

Twist ends of tie wires not less than two full turns and bent so as not to present a hazard.

3.11 BOTTOM TENSION WIRE

A. Install bottom tension wires before installing chain-link fabric, and pull wires taut. Place bottom tension wires as indicated on the plans

3.14 POST CAPS

A. Install post caps on all vertical posts.

3.15 GROUNDING AND BONDING

A. Ground fencing as indicated and specified:

1. Fences crossed by overhead powerline must be grounded. Electrical equipment attached to the fenced must be grounded. Ground fence on each side of all gates, at each corner, at the closest approach to each building located within 50 feet of the fence, and where fence alignment changes more than 15 degrees. Grounding locations must not exceed 750 feet. Bond each gate panel with a flexible bond strap to its gate post Ground fences crossed by powerlines of 600 volts or more at or near the point of crossing and at distances not exceeding 150 feet on each side of the crossing. Ground conductor must consist of No. 6 AWG solid copper wire. Grounding electrodes must be 5/8 inch by 8 foot long copper-clad steel rod. Drive electrodes into

Facilities Management 32 31 13 - 10 the earth so that the top of the electrode is at least 6 inches below grade. Clamp Ground conductor to the fence and electrodes with bronze grounding clamps top create electrical continuity between fence posts, fence fabric, and ground rods. Total resistance of the fence to the ground must not be greater than 25 ohms.

2. Make connections so possibility of galvanic action or electrolysis is minimized. Select connectors, connection hardware, conductors, and connection methods so metals in direct contact will be galvanically compatible.

3. Use electroplated or hot-tin-coated materials to ensure high conductivity and to make contact points closer in order of galvanic series

4. Coat and seal connections having dissimilar metals with inert material to prevent future penetration of moisture to contact surfaces. Retain paragraph below if fencing terminates at a building or other structure equipped with lightning protection system.

5. Bonding to Lightning Protection System: If fence terminates at lightning-protected building or structure, ground the fence and bond the fence grounding conductor to lightning protection down conductor or lightning protection grounding conductor complying with

NFPA 780.
