EXECUTION

EXAMINATION

Examine areas and conditions, with Installer present, for compliance with requirements for site clearing, earthwork, and other conditions affecting performance of the Work.

Proceed with installation only after unsatisfactory conditions have been corrected.

PREPARATION

Stake locations of fence lines, gates, and terminal posts. Do not exceed intervals of 300 feet or line of sight between stakes. Indicate locations of utilities, lawn sprinkler system, underground structures, benchmarks, and property monuments.

CHAIN-LINK FENCE INSTALLATION

Install chain-link fencing according to ASTM F567 and more stringent requirements specified.

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

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

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

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

Concealed Concrete: Place top of concrete 2 inches below grade to allow covering with surface material.

Terminal Posts: Install terminal end, corner, and gate posts according to ASTM F567 and terminal pull posts at changes in horizontal or vertical alignment of 15 degrees or more. For runs exceeding 500 feet, space pull posts an equal distance between corner or end posts.

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

Post Bracing and Intermediate Rails: Install according to ASTM F567, maintaining plumb position and alignment of fence posts. Diagonally brace terminal posts to adjacent line posts with truss rods and turnbuckles. Install braces at end and gate posts and at both sides of corner and pull posts.

Locate horizontal braces at midheight of fabric 72 inches or higher, on fences with top rail. Install so posts are plumb when diagonal rod is under proper tension.

Tension Wire: Install according to ASTM F567, maintaining plumb position and alignment of fence posts. Pull wire taut, without sags. Fasten fabric to tension wire hog rings of same material and finish as fabric wire, spaced a maximum of 24 inches. Install tension wire fully before stretching fabric. Provide horizontal tension wire at the following locations:

Extended along bottom of fence fabric. Install bottom tension wire within 6 inches of bottom of fabric and tie to each post with not less than same diameter and type of wire.

Top Rail: Install according to ASTM F567, maintaining plumb position and alignment of fence posts. Run rail continuously through line post caps, bending to radius for curved runs and terminating into rail end attached to posts or post caps fabricated to receive rail at terminal posts. Provide expansion couplings as recommended in writing by fencing manufacturer.

Chain-Link Fabric: Apply fabric to outside of enclosing framework. Leave 1-inch bottom clearance between finish grade or surface and bottom selvage unless otherwise indicated. Pull fabric taut and tie to posts, rails, and tension wires. Anchor to framework so fabric remains under tension after pulling force is released.

Tension or Stretcher Bars: Thread through fabric and secure to end, corner, pull, and gate posts, with tension bands spaced not more than 15 inches o.c.

Tie Wires: Use wire of proper length to firmly secure fabric to line posts and rails. Attach wire at one end to chain-link fabric, wrap wire around post a minimum of 180 degrees, and attach other end to chain-link fabric according to ASTM F626. Bend ends of wire to minimize hazard to individuals and clothing.

Maximum Spacing: Tie fabric to line posts at 12 inches o.c. and to braces at 24 inches o.c.

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

GATE INSTALLATION

Install gates according to manufacturer's written instructions, level, plumb, and secure for full opening without interference. Attach fabric as for fencing. Attach hardware using tamper-resistant or concealed means. Install ground-set items in concrete for anchorage. Adjust hardware for smooth operation.

GATE-OPERATOR INSTALLATION

Install gate operators according to manufacturer's written instructions, aligned and true to fence line and grade.

Excavation: Hand-excavate holes for posts, pedestals, and equipment bases/pads, in firm, undisturbed soil to dimensions and depths and at locations according to gate-operator component manufacturer's written instructions and as indicated.

Ground electric-powered motors, controls, and other devices according to NFPA 70 and manufacturer's written instructions.

GROUNDING AND BONDING

Comply with requirements in Section 260526 "Grounding and Bonding for Electrical Systems."

Connections:

Make connections with clean, bare metal at points of contact.

Make aluminum-to-steel connections with stainless-steel separators and mechanical clamps.

Make aluminum-to-galvanized-steel connections with tin-plated copper jumpers and mechanical clamps.

Make above-grade ground connections with mechanical fasteners.

Make below-grade ground connections with exothermic welds.

Coat and seal connections having dissimilar metals with inert material to prevent future penetration of moisture to contact surfaces.

ADJUSTING

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.

Automatic Gate Operator: Energize circuits to electrical equipment and devices, start units, and verify proper motor rotation and unit operation.

Test and adjust operators, controls, alarms, and safety devices. Replace damaged and malfunctioning controls and equipment.

Lubricate operator and related components.

Lubricate hardware and other moving parts.
