Chain link fence fabric shall conform to the requirements of Subsection 902- 2.04 of the specifications for fabric using 11 gauge wire. Woven wire fabric shall be of the same kind used for the adjoining woven wire fence. When the adjoining fence is barbed wire fence, gate fabric shall be of the kind used with Type 2 woven wire fence. Gates shall be hung by at least two steel, ductile iron, or malleable iron hinges so designed as to securely clamp to the type of gate post furnished and permit the gate to be swung back against the fence.

Above the top fence wire and below the bottom fence wire, a double strand of steel wire shall be placed around the latch post forming loops of such size that they will accept the ends of the latch board. A pry stick shall be sewed to the gate post so as to draw the fence to a taut condition when closed. The latch board and pry stick assembly shall be made of wood or of steel. Wood shall be clear select Douglas fir, 2 inch by 2 inch by 4 feet for the latch board and 2 inch by 2 inch by 2 feet for the pry stick. Steel latch board and pry stick shall be fab ricated from the same type of steel utilized for line posts. TABLE OF CONTENTS INDEX 1030 903- 3 Construction Requirements: 903- 3.01 General: In areas where there is livestock, the contractor shall take all measures necessary to restrict the livestock to the land where it is being kept. The contractor shall furnish all materials and construct temporary fence, gates and cattle guards as may be necessary to restrict the livestock as specified. Existing fences that are to remain in place and which have been damaged by the contractor's operations shall be replaced or restored by the contractor at no additional cost to the Department in accordance with the provisions of Subsection 107.11 of the specifications. The contractor shall clear the fence lines of all earth, trees, brush and other o bstructions which interfere with the proper construction of the fences, unless the Engineer orders certain trees to remain in place. Clearing the fence line shall be within the highway right -of-way. Disposal of removed material shall be in accordance with the requirements of Subsection 201- 3.02 of the specifications. Fence shall be constructed within the highway right -of-way as shown on the plans. 903- 3.02 Setting Fence: Fence posts shall be spaced at the intervals and set to the depths show n on the plans. In determining the post spacing, measurements shall be made parallel to the ground slope, and all posts shall be placed in a vertical position, except in unusual locations where the Engineer may direct that the posts be set perpendicular to the ground surface. Line posts may be driven into undisturbed earth provided driving does not injure the posts. All voids around the post shall be backfilled and the material thoroughly tamped. End, corner, pull, latch and gate posts and braces shall be set in concrete footings crowned at the top to shed water. Any high points which interfere with the placing of wire fence fabric shall be excavated to provide the clearance shown on the plans. Changes in the horizontal alignment of the fence line where the angle of deflection is 15 degrees or more shall be considered as corners and a corner post assembly shall be installed. Changes in fence alignment where the angle of deflection is less than 15 degrees but more than 5 degrees shall be considered as alignment angles and diagonal tension TABLE OF CONTENTS INDEX 1031 wires shall be installed. The diagonal tension wires shall consist of two twisted steel wires and shall be attached to the adjacent line posts. Where the fence line intersects a cross fence, the wires of the existi ng cross fence shall connect to an end post assembly as shown on the plans. Connecting fence assemblies with braces for every direction of strain shall be placed at the junction with new fences. Intermediate post assemblies shall be installed at not more t han 650- foot intervals between other braced posts, but for woven wire fence the spacing shall be such as to use standard rolls of fabric with a minimum of cutting and waste. After post assemblies have been placed, the barbed wire and woven wire fabric shall be pulled taut to the satisfaction of the Engineer, and each longitudinal wire shall be cut and securely fastened to the braced post with devices customarily used for the purpose. Barbed wire or woven wire fabric shall not be carried past a post assembly, but shall be cut and fastened to the post independently of the adjacent spans. A maximum of two splices on barbed wire will be permitted between post assemblies, but not on the same wire. No splice shall be placed closer than 100 feet to any post assembly. Where fence lines are interrupted by openings for gates and cattle guards, intermediate post assemblies shall be installed at both sides of the opening at a distance of one panel width from the end of the opening. After the tensioning of the barbed wire or woven wire fabric between two post assemblies, all longitudinal wires shall be attached to each intervening line post at the height and spacing as shown on the plans. The distance from the bottom wire to the ground may vary at any one point from t hat shown on the plans 4 inches plus or minus for barbed wire fence and game fence and 1 inch plus or minus for woven wire fence. Where abrupt changes occur in the fence line grade, intermediate line posts may be required to maintain proper distances betw een the bottom wire and the ground. Spacing of the twisted vertical wire stays shall be as shown on the plans for each type of fence. The vertical wire stays shall be woven into every horizontal wire for each type of fence. At all grade depressions where stresses tend to pull the posts from the ground, the affected fence posts shall be anchored in concrete or the fence wires shall be weighted with concrete sag weights. The volume of concrete required to anchor the posts shall be not less than 1 cubic foot . Fence sag weights shall weigh not less than 100 pounds and shall be made with a wire loop hanger embedded in the concrete. A double strand of wire shall be attached to each horizontal line of barbed wire and to the top and bottom wire of the woven wire fabric and tied to the wire loop hanger of the sag weight. TABLE OF CONTENTS INDEX 1032 903- 3.03 Flood Gates: Flood gates shall be constructed at the locations specified on the project plans or where designated by the Engineer and in accordance with the details shown on the project plans. If the length of the flood gate is such that the Engineer determines that line posts are needed, the posts shall be placed as necessary and driven to the depth required to keep the flood gate upright. Flood gates shall be constructed to the same requirements specified for barbed wire fence construction, except that the concrete sag weights shall weigh 35 pounds. 903- 4 Method of Measurement: Wire fence will be measured by the linear foot of each type of fence specified. Measurement will be made along the top of the completed fence from outside to outside of end posts, excluding the widths of gate and cattle guard openings. Gate posts and latch posts will be considered as included in the measurement of the completed fence. Type 1 g ates will be measured as a complete unit in place by the width of the gate opening. Double gates will be measured as one complete unit by the width of the gate opening. A gate unit complete in place shall include the gate with all necessary fittings, har dware, and gate bracing. Type 2 gates will be measured as a complete unit in place by the width of the gate opening. A gate unit complete in place shall include the wire gate with vertical stays, latch board and pry stick. Flood gates will be measured by the linear foot. Measurement will be made on the fence line along the top wire from gate post to gate post as shown on the plans, but exclusive of any Type 2 gates. 903- 5 Basis of Payment: The accepted quantities of wire fence and flood gates, measured as provided above, will be paid for at the contract unit price per linear foot for the type of fence and gate designated in the bidding schedule, complete in place. Types 1 and 2 gates, measured as provided above, will be paid for at the contract unit price per gate for the type designated in the bidding schedule, complete in place. No payment will be made for furnishing materials and constructing temporary fence, gates and cattle guards as may be necessary to restrict livestock.
