Barbed Tape, Fences, High Security Sliding Gate, Wire Ropes.

Supply and installing high-security fence around the perimeter of the facility, shall ensure the products compliance with relevant security standards and regulations, also the fencing system is integrated with advanced surveillance and detection system.

Surveillance systems with the fencing system:
Install surveillance cameras, motion sensors, and other detection devices along the perimeter fence to enhance situational awareness.

High Security Fencing System Solution for Assets and Facilities

The fencing system is designed for the safety and security of personnel, assets and facilities in a high-risk environment.

Primary components of the fencing system include three means of protection:

Chain Link Fence: Galvanized chain link fence forms the first layer of the perimeter security system. This type of mesh fence provides a visible deterrent and serves as a physical barrier against unauthorized entry.

Barbed Tape: Positioned atop the chain link fence is a layer of barbed tape, also known as razor wire. Barbed tape consists of sharp, jagged edges that act as a formidable deterrent to potential intruders, further enhancing the security of the perimeter.

Cable Reinforcement: In addition to the chain link fence and barbed tape, the perimeter security system include cable reinforcement. Steel cables are installed along the length of the fence and gates, providing additional support.

3.2 INSTALLATION

3.2.1 Installation Drawings
Submit complete Fence Installation Drawings for review and approval by the Contracting Officer prior to shipment. Submit drawing details that include, but are not limited to the following information: Fence Installation Drawings, Location of gate, corner, end, and pull posts, Gate Assembly, and Gate Hardware and Accessories. Install fence system per approved drawings.

3.2.2 Security Fencing
Install new security fencing, remove existing security fencing, and perform related work to provide continuous security for facility. Schedule and fully coordinate work with Contracting Officer.

3.2.3 Posts

3.2.3.1 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 457 mm in rock. Where solid rock is covered with an overburden of soil or loose rock, set posts to the minimum depth indicated on the drawing unless a penetration of 457 mm 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. Set portions of posts not set in rock in concrete from the rock to ground level. Set posts in holes not less than the diameter shown on the drawings. Make diameters of holes in solid rock at least 25 mm 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 914 mm and protect with drive caps when setting.
• c. Test fence post rigidity by applying a 222.4 newtons force on the post, perpendicular to the fabric, at 1.52 m above ground. Ensure post movement measured at the point where the force is applied is less than or equal to 19 mm 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. Remove, replace, and retest all failed parts at the Contractor's expense.

3.2.3.2 Concrete Slabs and Walls
When installed in concrete slabs or walls, set posts in zinc-coated sleeves, to a minimum depth of 300 mm. Fill sleeve joint with lead, nonshrink grout, or other approved material. Set posts for support of removable fence sections in sleeves that provide a tight sliding joint and hold posts aligned and plumb without use of lead or setting material.

3.2.4 Supporting Arms
Install barbed wire supporting arms and barbed wire as indicated on the drawings and as recommended by the manufacturer. Anchor supporting arms with 9.5 mm diameter plain pin rivets or, at the Contractor's option, with studs driven by low-velocity explosive-actuated tools for steel, wrought iron, ductile iron, or malleable iron. Do not use explosive-actuated tool to drive studs into gray iron or other material that can be fractured. Use a minimum of two studs per support arm. Pull barbed wire taut and attach to the arms with clips or other means that will prevent easy removal.

3.2.5 Barbed Tape Installation
Install stainless steel reinforced barbed tape per ASTM F1911 and as detailed on the drawings. Stretch out barbed tape to its manufacturer's recommended length, set on top of the barbed wire and "V" shaped support arms, then secure it to the barbed wire. Secure the barbed tape to the barbed wire at the two points and at every spiral turn of both coils as shown on the drawings.

3.2.6 Gate Installation

a. Install gates at the locations shown. Install latches, stops, and keepers as required. Install Slide gates as recommended by the manufacturer.

b. Attach padlocks to gates or gate posts with chains. Weld or otherwise secure hinge pins, and hardware assembly to prevent removal.

c. Submit 6 copies of operating and maintenance instructions. Outline the step-by-step procedures required for system startup, operation, and shutdown. Include the manufacturer's name, model number, service manual, parts list, and brief description of all equipment and their basic operating features. Include in the maintenance instructions routine maintenance procedures, possible breakdowns and repairs, and troubleshooting guide. Also include the general gate layout, equipment layout and simplified wiring and control diagrams of the system as installed.

3.2.7 Grounding

a. Ground fencing as specified.

b. Ground fences on each side of all gates, at each corner, at the closest approach to each building located within 15 m of the fence, and where the fence alignment changes more than 15 degrees. Ensure grounding locations are located no more than 198 m apart. 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 45 m on each side of crossing.

c. Provide ground conductor consisting of 3.3 mm solid copper wire. Use grounding electrodes that measures 19 mm by 3.05 m long and are a copper-clad steel rod. Drive electrodes into the earth so that the top of the electrode is at least 152 mm below the grade. Where driving is impracticable, bury electrodes a minimum of 305 mm deep and radially from the fence. Install the top of the electrode to be less than 610 mm or more than 2.4 m from the fence. Clamp ground conductorto the fence and electrodes with bronze grounding clamps to create electrical continuity between fence posts, fence fabric, and ground rods. Measure total resistance of the fence to ground and ensure it is not greater than 25 ohms.

3.2.8 Cable Reinforcement Installation
Comply with the contract drawings. Install 2 strands of 1.9 cm steel aircraft cables mounted to the chain link fence posts utilizing u-bolts and nuts. Peen the ends of the U-bolts to prevent removal. Tighten cables with galvanized steel turnbuckles with swaged fittings to the point there is no visible sag. Install .3 m x 1.3 m x 0.66 m concrete deadman anchors which are a minimum of 1.3 m underground and installed in undisturbed surrounding soils. Space dead man anchors no more than 61 m apart and on each side of gate openings. Connect steel aircraft cables to dead man anchors using swaged end fittings and turnbuckles attached to 3.2 cm galvanized threaded rod which is embedded into concrete anchor and held in place with two 10 cm x 10 cm x 0.66 cm thick steel plates welded to the threaded rod. Place deadman anchors within 3 m of last post and on each side of gate openings.
