3.3 INSTALLATION OF CHAIN-LINK FENCING

A. Install chain-link fencing in accordance with ASTM F567 and more stringent requirements specified.

B. Install fencing on established boundary lines inside property line.

C. Post Excavation: Drill or hand-excavate holes for posts to diameters and spacings indicated, in firm, undisturbed soil.

D. Post Setting: Set posts in concrete at indicated spacing into firm, undisturbed soil.

1. Verify that posts are set plumb, aligned, and at correct height and spacing, and hold in position during setting with concrete or mechanical devices.

2. Concrete Fill: Place concrete around posts to dimensions indicated and vibrate or tamp for consolidation. Protect aboveground portion of posts from concrete splatter.

a. Exposed Concrete: Extend 2 inches above grade; shape and smooth to shed water.

E. Terminal Posts: Install terminal end, corner, and gate posts in accordance with ASTM F567 and terminal pull posts at changes in horizontal or vertical alignment of 15 degrees or more, at any abrupt change in grade, and at intervals not greater than 500 feet. For runs exceeding 500 feet, space pull posts an equal distance between corner or end posts.

F. Line Posts: Space line posts uniformly at 10 feet o.c.

G. Barbed Wire Arms: Bolt or rivet to top of post. Angle single arms away from approach side of fence.

H. Tension Wire: Install in accordance with ASTM F567, maintaining plumb position and alignment of fence posts. Provide horizontal tension wire at the following locations:

1. Extended along top of fence fabric.

I. Bottom Rails: Secure to posts with fittings; anchor rail at midspan to concrete footing.

J. Chain-Link Fabric: Apply fabric on the approach side of fence, inside of enclosing framework. Pull fabric taut and tie to posts, rails, and tension wires. Anchor to framework so fabric remains under tension after pulling force is released.

1. Overlapping Fabric: Overlap ends of fence fabric at or between posts or rails;

overlap 6 inches and secure with wire ties or steel strap method.

2. Bottom Clearance: Leave 2 inches between finish grade or surface and bottom selvage unless otherwise indicated.

K. Fasteners: Install nuts for tension bands and carriage bolts on the side of fence opposite the fabric side.

Gates: Adjust gates to operate smoothly, easily, and quietly, free of binding, warp, excessive deflection, distortion, nonalignment, misplacement, disruption, or malfunction, throughout entire operational range. Confirm that latches and locks engage accurately and securely without forcing or binding.

B. Lubricate hardware and other moving parts.
