Install fence system per approved drawings.

3.2.2 Security Fencing

Install new security fencing, remove existing security fencing, and perform related work to provide continuous security for facility.

Schedule and fully coordinate work with Contracting Officer.

3.2.3 Posts

3.2.3.1 Earth and Bedrock

a. Set posts plumb and in alignment. Except where solid rock is encountered, set posts in concrete to the depth indicated on the drawings. Where solid rock is encountered with no overburden, set posts to a minimum depth of 18 inches in rock. Where solid rock is covered with an overburden of soil or loose rock, set posts to the minimum depth indicated on the drawing unless a penetration of 18

SECTION 32 31 13.53 Page 15 inches in solid rock is achieved before reaching the indicated depth, in which case terminate depth of penetration. Grout all portions of posts set in rock.

b. Set portions of posts not set in rock in concrete from the rock to ground level. Set posts in holes not less than the diameter shown on the drawings. Make diameters of holes in solid rock at least 1 inch greater than the largest cross section of the post. Thoroughly consolidate concrete and grout around each post, free of voids and finished to form a dome. Allow concrete and grout to cure for 72 hours prior to attachment of any item to the posts. Group II line posts may be mechanically driven, for temporary fence construction only, if rock is not encountered. Set driven posts to a minimum depth of 3 feet and protect with drive caps when setting.

c. Test fence post rigidity by applying a 50 pound force on the post, perpendicular to the fabric, at 5 feet above ground. Ensure post movement measured at the point where the force is applied is less than or equal to 3/4 inch from the relaxed position. Test every tenth post for rigidity. When a post fails this test, make further tests on the next four posts on either side of the failed post. Remove, replace, and retest all failed parts at the Contractor's expense.

3.2.3.2 Concrete Slabs and Walls

When installed in concrete slabs or walls, set posts in zinc-coated sleeves, to a minimum depth of 12 inches. Fill sleeve joint with lead, nonshrink grout, or other approved material. Set posts for support of removable fence sections in sleeves that provide a tight sliding joint and hold posts aligned and plumb without use of lead or setting material.

3.2.4 ORNAMENTAL FENCE INSTALLATION MAINTENANCE

When cutting/drilling fence system components adhere to the following steps to seal the exposed steel surfaces; 1) Remove all metal shavings from cut area. 2) Apply zinc-rich primer to thoroughly cover cut edge and/or drilled hole; let dry. 3) Apply 2 coats of custom finish paint matching fence color. Failure to seal exposed surfaces per steps 1-3 above will negate warranty. Spray cans or paint pens shall be used to prime and finish exposed surfaces; it is recommended that paint pens be used to prevent overspray. Use of non-manufacturer approved parts or components will negate the manufactures’ warranty.

3.2.5 Turnstile installation

The minimum conditions necessary to initiate installation are:

a. Grade must be dead level at any point within the footprint of the door.

b. Finished surface must be installed, complete with conduit supplied to meet manufacturer's specified drawings.

c. Power supply (110 VAC) must be installed. Power and communication come from the floor to the secure side of the cabinet.

3.2.5.1 Erection

Install turnstile in accordance with manufacturer's printed instructions.

Set units level, plumb, and with uniform hairline joints. Anchor securely into place. Use only factory trained installers.

SECTION 32 31 13.53 Page 16

3.2.5.2 Adjustment

Installer shall adjust turnstile for smooth operation and proper performance.

3.2.5.3 Maintenance

Follow maintenance procedures as outlined in the Operation Maintenance Manual.

3.2.5.4 Cleaning

Clean metal surfaces carefully after installation to remove excess caulk, dirt and labels.

3.2.6 Fabric

a. Set fabric height at 7 feet.

b. Install chain link fabric on the opposite side of the post of the area being secured. Attach fabric to terminal posts with stretcher bars and tension bands. Space bands at approximately 15 inch intervals.

Install fabric and pull taut to provide a smooth and uniform appearance free from sag, without permanently distorting the fabric diamond or reducing the fabric height. Fasten fabric to line posts at approximately 15 inch intervals and fastened to all rails and tension wires at approximately 12 inch intervals.

c. Cut fabric by untwisting and removing pickets. Accomplish splicing by weaving a single picket into the ends of the rolls to be joined.

Install the bottom of the fabric 2 plus or minus 1/2 inch above the ground.

d. After the fabric installation is complete, exercise the fabric by applying a 50 pound push-pull force at the center of the fabric between posts; use a 30 pound pull at the center of the panel to ensure fabric deflection of not more than 2.5 inches when pulling fabric from the post side of the fence. Every second fence panel is required to meet this requirement. Resecure and retest all failed panels at the Contractor's expense.

3.2.7 Supporting Arms

Install barbed wire supporting arms and barbed wire as indicated on the drawings and as recommended by the manufacturer. Anchor supporting arms to the posts in a manner to prevent easy removal with hand tools. Pull barbed wire taut and attach to the arms with clips or other means that will prevent easy removal.

3.2.8 Gate Installation

a. Install gates at the locations shown. Mount gates to swing inward.

Install latches, stops, and keepers as required. Install gates as recommended by the manufacturer.

b. Attach padlocks to gates or gate posts with chains. Weld or otherwise secure hinge pins, and hardware assembly to prevent removal.

SECTION 32 31 13.53 Page 17

c. Submit 6 copies of operating and maintenance instructions. Outline the step-by-step procedures required for system startup, operation, and shutdown. Include the manufacturer's name, model number, service manual, parts list, and brief description of all equipment and their basic operating features. Include in the maintenance instructions routine maintenance procedures, possible breakdowns and repairs, and troubleshooting guide. Also include the general gate layout, equipment layout and simplified wiring and control diagrams of the system as installed.

3.2.9 Grounding

a. Ground fencing as indicated on drawings and specified.

3.2.10 Cable Reinforcement Installation

Comply with the contract drawings. Install three strands of 3/4 inch cables or two strands of one-inch in steel aircraft cables mounted to the ornamental fence system posts utilizing u-bolts and nuts. Peen the ends of the U-bolts to prevent removal. Tighten cables with galvanized steel turnbuckles with swaged fittings to the point there is no visible sag.

Install concrete deadman anchors, size as determined by Cable Reinforcement Design, which are a minimum of 3 ft underground and installed in undisturbed surrounding soils. Space dead man anchors no more than 200 ft apart and on each side of gate openings. Connect steel aircraft cables to dead man anchors using swaged end fittings and turnbuckles attached to 1.25 in galvanized threaded rod which is embedded into concrete anchor and held in place with steel plates welded to the threaded rod. Dimensions of rods and steel plates shall be in conformance with Cable Reinforcement design. Place deadman anchors within 10 feet of last post and on each side of gate openings.

3.3 CLOSEOUT ACTIVITIES

3.3.1 Cleanup

Remove waste fencing materials and other debris from the work site each workday.
