Primary security line chain-link fence and barrier construction and upgrade


This section of the specification forms part of the Contract Documents. this section covers the chain-link fence and project barriers.

» Material Certification
Submit manufacturer's test data and certification al least 2 week prior to commencing work. Include stamped, signed, and dated manufacturer's drawings, information and shop drawing where pertinent.

» Security fence c/w perimeter barrier will be measured in metres. Our services include materials, installation, testing, grading, compacting and all work incidental to the completed Work. Supply and installation of the chain link mesh, all the posts, rails, braces, electrical grounds, barriers, tension wires and ties shall be incidental to the installation of the fence. Installation of the concertina razor wire shall also be incidental to the installation of the fence.


» Materials

The fabric shall be woven with a 9-gauge galvanized steel wire in a 2-inch(50 mm) mesh and shall meet the requirements of ASTM A 392, Class 2.

2, Razor Wire
Concertina razor wire shall be 2 - strand 12-1/2 gauge zinc-coated wire with razor barbs wire and shall conform to the requirements of ASTM A 121, Class 3, Chain Link Fence Grade.

3, Posts, rails and braces
Line posts, rails, and braces shall conform to the requirements of ASTM F-1043 or ASTM F 1083 as follows:
(1) Galvanized tubular steel pipe shall conform to the requirements of Group IA, (Schedule 40) coatings conforming to Type A, or Group IC (High Strength Pipe) , External coating Type B, and internal coating Type B or D.
(2) Posts, rails, and braces furnished for use in conjunction with aluminum alloy fabric shall be aluminum alloy or composite.
(3) Posts, rails, and braces, with the exception of galvanized steel conforming to F 1043 or ASTM F 1083, Group 1A, or aluminum alloy, shall demonstrate the ability to withstand testing in salt spray in accordance with ASTM B 117as follows:
(a) External: 1,000 hours with a maximum of 5% red rust.
(b) Internal: 650 hours with a maximum of 5% red rust.

4, Wire Ties and Tension Wires
Wire ties for use in conjunction with a given type of fabric type. Top and bottom tension wire shall be 7-gauge marcelled steel wire with the same coating as the fabric type and shall conform to ASTM A 824.

5, Miscellaneous Fittings and Hardware
Miscellaneous steel fittings and hardware for use with zinc-coated steel fabric shall be of commercial grade steel or better quality, wrought or cast as appropriated to the article, and sufficient in strength to provide a balanced design when used in conjunction with fabric posts, and wires of the quality specified herein. All steel fittings and hardware shall be protected with a zinc coating applied in conformance with ASTM A153. Razor barbed wire support arms shall withstand a load of 250 pounds(113 kg) applied vertically to the outermost end of the arm.

6, Concrete
Concrete shall be of a commercial grade with a minimum 28-day compressive strength of 3,000 psi(17 240 kPa).

» CLEARING FENCE LINE. All trees, brush, stumps, logs, and other debris which would interfere with the proper construction of the fence in the required location shall be removed a minimum width of 500 mm on each side of the fence centerline before starting fencing operations.

» INSTALLING POSTS. All posts shall be set on the concrete barriers at the required dimension and depth and shall be spaced not more than 3m apart and should be set a minimum of 400 mm in the concrete barrier. The posts holes shall be in proper alignment so that there is a minimum of 75 mm of concrete on all sides of the posts. The posts may be welded to a galvanized plate to be bolted on the concete barrier. Alternate connection details will be revicwed by the Airport Authority before approving the installation.
