PART 3 - EXECUTION

3.1 INSTALLATION

A. Installation shall be made in a workmanlike manner by skilled mechanics experienced in erection of this type of fence.

B. Fiberglass Rods shall be clamped to the line posts with stainless steel hose clamps of appropriate size and shall extend 40 inches above the top rail to help secure the concertina wire.

C. Razor Ribbon Wire General

1. Protective Gear: Mandatory protective gear: hardhats, goggles, gloves and steel toe shoes. Contact manufacture for additional information regarding protective gear.

2. Installation Equipment: Provide equipment adequate to support and protect the workers while installing coils at heights greater than 1830mm (72") above the finish grade.

Alternative methods are accepted, provided adequate precautions are taken.

3. Experience: Contractors not familiar with Barbed Tape Installation shall contract with the manufacture in order to have the manufacturer’s representative on the construction site during the initial installation. Installers shall have three years minimum experience.

Contractor is to obtain manufacturer’s installation instructions and final inspection services. Contractors shall arrange for these services a minimum of two weeks prior to the date needed.

4. Install work of this Section in accordance with the following general installation instructions and also with the manufacturer’s recommendations.

D. Wire Reinforced Barbed Tape – Detainer Hook Barb

1. Top of the Fence Installation (Interior, Exterior and Sallyport Fences):

a. Coils shall be installed horizontally on the approach side of the fence. Stretch out the coil and allow it to rotate (spiral) around its central axis.

b. Before attaching coils to the fence fabric, inspect the roll for tangles and proper coil spacing.

c. Locate the coil loops 300mm (12") o.c. and permanently or temporarily secure in place. If temporarily attached follow with another crew and complete the tying operation’

d. Since the obstacle is tied to the highest point on the fence, allow for off-center tying (above and below tie points). This tying method reduces coil movement; coil movement creates mechanical noise effecting most fence mounted electronic detection systems. Additional ties may be required to reduce any audible noise.

2. Side of the Fence Installation

a. Follow, “Top of the Fence Installation”, for deployment procedures, except that the 300mm (12") o.c. tie points are uniformly placed at the specified height.

Installation sequence will depend upon the security coil configuration.

b. Adjacent rows are attached one to the other 1220mm (48") o.c..

c.

3. Bottom of Fence Installation

a. Follow, “Top of the Fence Installation”, for deployment procedures.

b. Coils at the base of the fence are installed horizontally in vertical stacks and tied consecutively together.

c. Adjacent rows within the stack at attached one to the other at 1220mm (48") o.c..

Install the horizontal vertical stack systematically, bottom to top, starting next to the row attached to the fence and work outward.

4. Splicing

a. Symmetrical in shape, each roll has a splicing tail consisting of 4 to 8 barbs.

Connect the trailing ends of the preceding coils to the leading end of the following roll by aligning the end coils and matching the clip pattern around the circumference of the two rolls being connected. This will determine the number of barb clusters in the splice.

b. Tie the overlapping tails together by placing tie wires diagonally across a minimum of two pairs of barb clusters so as not to allow one barb slipping past another. Complete the splice by placing ties at two other locations diametrically opposite to the splicing tails where clips would have been if manufactured in one continuous roll.

E. Non-Reinforced Barbed Tape – 40” Diameter

1. Bottom of Fence Installation (Interior, Exterior and Sallyport Fences):

a. Same as Wire Reinforced Barbed Tape above.

b. Opposing rows installed on opposite sides of the fence are secured in the same manner as “Sides of the Fence Installation”, except those opposing rows are secured by reaching through the coils.

5. Splicing

a. Connect the trailing ends of the preceding roll to the leading end of the following roll. Each roll is manufactured symmetrical with a small diameter aircraft cable running the entire length of the roll.

b. Align end coils by matching barbs on each side of the cable connection. Place one or two tie wires diagonally across the cable connections, locking the cable and end coils together. This creates a continuous cable and aligns the remaining barb clusters around the circumference in line with existing spot welds. This gives the appearance of being manufactured in one continuous roll and completes the splice.

6. Ground Stakes

3.2 INSPECTION

A. The completed installation shall be inspected and approved by an authorized manufacturer's representative. Provide a certificate of compliance to the Contracting Officer indicating the installation meets or exceeds the manufacturer's written requirements for the application shown. Correct improperly installed work.

3.3 CLEAN UP

A. Upon the completion of the installation all debris created by the installation shall be legally removed from the premises or disposed of as directed by the State Unit. The excavated material removed from the footing holes shall be spread along the fence alignment, raked and blended in with the adjacent ground surface.
