SGFO Ware Yard Security Fencing Chain Link Fences and Gates 02821 - 4

B. Alignment and Setting of Posts: Set posts plumb, and align posts in holes 3 inches above bottom of excavation. Space a maximum of 10 feet center to center, unless otherwise staked or indicated on the drawings, to the grades indicated. Locate a terminal post at each change in horizontal or vertical direction of 30 degrees or more. Protect the portion of posts above ground from concrete splatter. Place concrete around posts and vibrate or tamp for consolidation. Extend concrete 2 inches above grade and trowel to a crown to shed water. Check each post for vertical, horizontal and top alignment, and hold in position during placement and finishing operations.

D. Top Rail and Tension Wire:

1. Support the top rail at each post so that a continuous brace from end to end of each stretch of fence is formed. Securely fasten the top rail to the terminal posts and join with sleeves or coupling to allow for expansion and contraction.

E. Fabric:

1. Place chain-link fabric on the outside of the area enclosed.

2. Place the fabric by securing one end, applying sufficient tension to remove slack before making attachment elsewhere. Tighten the fabric to provide a smooth uniform appearance free from sag.

3. Cut the fabric by untwisting a picket and attach each span independently at terminal posts. Use stretcher bars with tension bands at maximum 15 inch intervals or other approved method of attachment.

4. Install fence fabric 2 inch above ground level. Measure clearance at the post with a tolerance of plus or minus 3 inches. Fasten the fabric to the line posts at intervals not exceeding 15 inches.

Fasten the fabric to the rail or tension wire at intervals not exceeding 24 inches.

5. Join rolls of wire fabric by weaving a single picket into the ends of the rolls to form a continuous mesh.

F. Tension or Stretcher Bars: Thread through fabric and secure to end, corner, pull, or gate posts with tension bands spaced not over 15 inches center to center.

G. Tie Wires: Use wire of proper length to secure fabric firmly to posts and rails. Bend ends of wire to minimize hazard to persons or clothing.

1. Maximum Spacing: Tie fabric to line posts 12 inches center to center and to rails and braces 24 inches center to center.

H. Barbed Wire: Extend end members of gate frames above top member of gate to match the height of adjacent fence and prepare to receive the same

SGFO Ware Yard Security Fencing Chain Link Fences and Gates 02821 - 5 number of strands as adjacent arms of fence posts. Pull taut to remove sag, firmly install it in the slots of the extension arms and secure it.

Provide necessary clips for securing wire to extensions. Attach at maximum intervals of 8 ft.

I. Fasteners: Install nuts for tension bands and carriage bolts on the side of the fence opposite the fabric side. Peen ends of bolts or score threads to prevent removal of nuts.

PART 4 MEASUREMENT AND PAYMENT

A. Units: The work described in this section will be measured and paid for on a lump sum basis.
