FRAME WORK AND GATES
a)Galvanizing: Ferrous metal elements of the fence frame and accessories shall receive zinc (Grade E) coating by the hot dip process after fabrication. Metal coated to l.8 oz. of zinc coating per square foot of surface, in a smooth finish, free from dross, uncoated spots and foreign materials, in accordance with ASTM A l23.
b)Frame Work: Roll-formed shapes or tubular members with zinc hot-galvanized coating according to ASTM A 123, and comprised of the following components:
- Intermediate (Line) Posts: Nominal 2-1/2 inch roll formed shapes or tubular members fabricated from 50,000 psi minimum yield strength steel and weighing 3.12 lbs. per ft., or 2-1/2 inch schedule 40 at 3.65 per ft.
- End, Pull and Corner Posts: Nominal 3 inch roll formed shapes or tubular members fabricated from 50,000 psi minimum yield strength steel and weighing 5.10-lbs. per ft., or 3 inch schedule 40 at 5.79 lbs. per. ft.
- Gate Posts: Nominal 3-1/2 inch steel pipe or tubular members fabricated from 30,000 psi minimum yield strength steel and weighing 9.l0 lbs. per ft.
- Post Braces: Nominal l-5/8 inch steel pipe weighing 2.27 lbs. per ft. minimum, with 3/8 inch diameter truss rod and adjustable take-up device. Provide two brace assemblies at each corner post and one brace assembly at each end and gate post.
- Top Rail, Intermediate, and Bottom Rail: Nominal 1-5/8 inch steel pipe weighing 2.27 lbs. per ft. minimum.
- Barbed Wire Supporting Arms: Designed for three strands and of sufficient strength to withstand without failure, 200 lbs. downward pull at the end of the arm.
- Post Tops: Where barbed wire supporting arms are not required cover post ends with pressed steel or malleable iron, weather tight caps designed to permit passage of top rail, as required.
- Stretcher Bars: One piece 3/l6 x 3/4 inch bar of length equal to full height of fabric. Provide one bar for each gate and end post and two for each corner and pull post. Provide l/2 inch wide stretcher bar bands spaced not over l4 inches O.C. to secure stretcher bars to posts.
NOTE: Bottom of posts set not less than 36 inches in concrete base. Space line posts a maximum of ten feet on center.
c)Post Setting Concrete: Minimum 3,000 psi concrete as specified in Section 03300.
d)Swing Type Gate: Fabricated of nominal 1-7/8 inch tubular horizontal and vertical members and truss members assembled by welding. Provide the same fabric as fence and install with stretcher bars and bar ties at l4 inches O.C. Provide diagonal cross bracing of 3/8 inch diameter adjustable length truss rods. Attach gate hardware with rivets or by other means, which will provide security against removal. Gate hardware as follows:
- Hinges: Pressed steel or malleable iron to suit gate size, non-lift-off type, and offset to permit l80 degree swing. Provide one pair (top and bottom) per gate leaf.
- Latch: Forked or plunger-bar type to permit operation either side of gate. Provide padlock eye as integral part of latch. Provide gate stops for pair of gates designed to accept drop rod or plunger bar.
- Keeper: Provide keeper for each gate leaf that will hold gate leaf in open position until manually released.
3. Grounding and Bonding of Electrical Systems and Equipment
- Grounding system installation to be in compliance with UL 467 and NFPA 70 requirements
- Product Compatibility:
- Bare Copper Conductors: Comply with the following:
a)Solid Conductors: ASTMB3.
b)Assembly of Stranded Conductors: ASTMB8.
c)Tinned Conductors: ASTMB33.
- Connectors: Comply with the following:
a)IEEE837 and UL467; listed for use for specific types, sizes, and combinations of conductors and connected items
b)Bolted Connectors: Bolted-pressure-type connectors, or compression type
c)Welded Connectors: Exothermic-welded type, in kit form, and selected per manufacturer written instructions
C. Above Ground
1. For ground rings and interconnection of internal and external ground rings, #2 AWG or larger is required. Solid copper wire is permitted only. Internal ground ring and all external conductors must be bare.
2. For grounding of equipment and miscellaneous objects, green insulated #2 AWG stranded copper wire or #2 AWG bare tinned solid copper wire is required, except where specifically noted. All insulation is to be THHN rated.
3. #2 AWG bare tinned solid copper wire is to be used to connect tower guys to the ground rods (if applicable).
D. Below Ground
- Rings shall be bare tinned solid copper wire #2 AWG, minimum. All wire connected to ring shall be #2 AWG bare tinned solid copper wire.
- The new ground system will be installed using Bentonite clay.
a)The Bentonite material will be installed in a slurry mix according to the manufacturer’s recommendations.
b)Approximately 3” of Bentonite will encapsulate and surround the ground conductor on all sides.
c)Bentonite will be used to encapsulate all ground rings, all buried interconnecting ring to ring ground conductors and all ring to external equipment ground conductors.
- All ground conductors will be buried a minimum of 30” below the graded surface or below the frost line, whichever is deeper. All ground rods will be installed with a distance between rods of 2-times the length of the rod. Installation of up to (40) new 5/8”x10’ ground rods will be required.
E. Test-Wells
- Two Test-Wells will be installed per site. One Test-Well will be installed within the shelter ring at a point furthest from the tower ground ring. The second Test-Well will be installed off of a ground stub connected to the tower ring. Each Test-Well will consist of a minimum 8” diameter PVC pipe with screw on cap. The top of the ground conductor within the Test -Well is to be no more than 12” below finished surface level to allow access. The Test-Well ground conductor will be positioned within the well in a position allowing access and measurement by a technician using a clamp style resistance meter.
