### ITEM F-163 WILDLIFE DETERRENT FENCE

DESCRIPTION

**163-1.1** This item shall consist of furnishing and installing
chain-link fence fabric underground along an existing chain link fence,
constructing concrete pads at existing fence gates in accordance with
these specifications and the details shown on the drawings and in
conformity with the lines and grades shown on the plans or established
by the Engineer.

MATERIALS

**163-2.1 CHAIN LINK FENCE FABRIC.** The fabric shall be woven with a
9-gauge galvanized steel wire in a 2-inch (50 mm) mesh and shall meet
the requirements of ASTM A 392, Class II. The fabric shall be 5\'-0\"
wide.

**163-2.2 BARBED WIRE.** Barbed wire shall be 2-strand 12-1/2 gauge
zinc-coated wire with 4-point barbs and shall conform to the
requirements of ASTM A 121, Class 3.

**163-2.3 WIRE TIES AND TENSION WIRES.** Wire fabric ties, wire ties,
and tension wire for use in conjunction with a given type of fabric
shall be of the same material identified with the fabric type. The
tension wire shall be 7-gauge coiled spring wire coated similarly to the
respective wire fabric being used.

Wire fabric ties shall be hog rings of galvanized steel wire not less
than 9-gauge.

All material shall conform to Fed. Spec. RR-F-191/4.

**163-2.4 MISCELLANEOUS FITTINGS AND HARDWARE.** Miscellaneous steel
fittings and hardware for use with zinc-coated steel fabric shall be of
commercial grade steel or better quality, wrought or cast as appropriate
to the article, and sufficient in strength to provide a balanced design
when used in conjunction with fabric posts, and wires of the quality
specified herein. All steel fittings and hardware shall be protected
with a zinc coating applied in conformance with ASTM A 153.

**163-2.5 CONCRETE PADS AT GATES.** Concrete shall be of a commercial
grade with a minimum 28-day compressive strength of 3000 psi.

**163-2.6 MARKING.** Each roll of fabric shall carry a tag showing the
kind of base metal, kind of coating, the gauge of the wire, the length
of fencing in the roll, and the name of the manufacturer. Posts, wire,
and other fittings shall be identified as to manufacturer, kind of base
metal, and kind of coating.

**163-2.7 WEED CONTROL MATERIAL.** A commercially available weed control
material shall be applied at the manufacturer's recommended rate.

CONSTRUCTION METHODS

**163-3.1 CLEARING FENCE LINE.** All brush, stumps, logs, and other
debris which would interfere with the proper construction of the fence
in the required location shall be removed a minimum width of 4 feet on
the side of the fence centerline before starting fencing operations. The
material removed and disposed of shall not constitute a pay item and
shall be considered incidental to fence construction.

**163-3.2 INSTALLING FABRIC.** Excavate ground to the depth required for
proper installation of the fabric. Obtain Engineer's approval of depth
of excavation before placing the wire fabric. Place the fabric and lap
splice it to existing fence fabric and tie with wire ties at 2 foot 0
inch spacing. Cut wire fabric around fence post footing to allow proper
placement. Backfill with native soil to original grade. Compact all
backfill and fill to attain 90% of AASHTO T-180.

**163-3.3 WEED CONTROL APPLICATION.** Weed control material shall be
applied over an area 3 feet wide, measured from the fence centerline,
and over the wildlife fence. Apply weed control material as recommended
by the manufacturer's instructions and in compliance with state and
local regulations.

METHOD OF MEASUREMENT

**163-4.1 CHAIN LINK FENCE FABRIC.** Chain-link fence fabric shall be
measured for payment by the linear foot to the nearest foot. Measurement
shall be along the fence from center to center of end or corner posts,
excluding the length occupied by gate openings.

**163-4.2 CONCRETE PADS AT GATES.** Concrete pads at gates shall be
measured by the unit.

**163-4.3 BORROW FILL MATERIAL.** Borrow material for fill will be
furnished by the Contractor. This shall be measured by the cubic yard in
place.

**163-4.4 WEED CONTROL APPLICATION.** Shall be measured by the linear
foot.

BASIS OF PAYMENT

**163-5.1 CHAIN LINK FENCE FABRIC.** Payment for chain-link fence fabric
shall be made at the contract unit price per linear foot. This price
shall be full compensation for furnishing materials, all labor
(including preparation, excavation, backfill, fill, and installation),
equipment, tools, and incidentals necessary to complete this item.
Utility locates shall be included in this pay item.

**163-5.2 CONCRETE PADS AT GATES.** Payment for concrete pads at gates
shall be made at the contract unit price for each pad. This price shall
be full compensation for furnishing materials, all labor (including
preparation, excavation, backfill, placement of concrete, reinforcing
steel, and forms), equipment, tools, and incidentals necessary to
complete this item.

**163-5.3 BORROW FILL MATERIAL.** Payment for the loading, transporting,
and placing of borrow material shall be made at the contract unit price
per cubic yard. This price shall be full compensation for furnishing all
labor (including placement, compaction, and grading), equipment, tools,
and incidentals necessary to complete this item.

**163-5.4 WEED CONTROL APPLICATION.** Payment for weed control
application shall be made at the contract unit price per linear foot.
This price shall be full compensation for furnishing materials, all
labor, equipment, tools, and incidentals necessary to complete this
item.
