At locations where breaks in a run of fencing are required, or at intersections with existing fences, appropriate adjustment in post spacing shall be made in accordance with the requirements for the type of closure indicated. When the plans require that posts, braces, or anchors be imbedded in concrete, 30 temporary guys or braces shall be installed, if required to hold the posts in proper position. Unless otherwise specified, no materials shall be installed on posts or strain placed on guys and bracing shall be set in concrete until 96 h have elapsed from the time of placing of the concrete. The tops of all posts shall be set to the required grade and alignment. Cutting of the posts will only be allowed with the approval by the Engineer. Post caps shall be installed at the time the fence fabric is placed on the posts.
Wire or fencing of the size and type required shall be firmly attached to the posts 40 and braces in the manner indicated. All wires shall be stretched taut and installed to the required elevations. At each location where an electric transm ission, distribution, or secondary line crosses any of the types of fences covered by these specifications, a ground, conforming to applicable requirements of the NEC, shall be furnished and installed. 603.04 Setting Posts Posts, including the concrete foundation for posts, braces and anchors shall be set so that the entire fence is inside the right-of-way and th e fence can be placed on the 50 side of the post facing the roadway. If an object, such as a tree, is located on the right- of-way and is to remain in place, the fence may be adjusted to miss the obstruction. There shall be a gradual offset for at least three posts in each direction of the obstruction. Line posts for farm field type fence shall be set on 16 ft centers, and for chain link fence on 10 ft centers. In either case, a tolerance of ±2 ft in spacing will be allowed at special locations as approved. Spacing of thes e posts shall be as uniform as practicable under the existing conditions. Additional posts shall be set to maintain the bottom clearance dimensions as required. 60
Pull posts shall be set at 500 ft maximum intervals in straight runs and at each vertical angle point of 10° or more. Corner posts shall be set at each hor izontal angle point of 10° or more.
End, corner, and pull posts for both types of fence, line posts for chain link fence and diagonal braces for farm field type fence shall be set in concrete as shown on the plans. 70 603.04 499 Except where rock is encountered, intermediate or line posts shall be driven and furnished with an approved anchor plate or other satisfactory device to hold the post in proper alignment and plumb. The plate or anchor shall be welded or riveted to the post with no less than two rivets. Gate posts shall be set in concrete as shown on the plans. Extra length posts shall be required at stream crossings as shown on the plans or as directed and also at ground depressions where it is not practicable for the fencing to follow closely the contour of the ground. These posts shall be set in concrete as 80 shown on the plans. At small stream crossings and ground depressions, the space below the fence fabric shall be closed with barbed or ground tension wire, either on horizontal lines or fanned, as shown on the plans or as directed. The wires shall be stretched taut between and fastened to the posts to prevent vertical movement of the wires. Barbed or tension wire shall not be placed where its installation would cause collecting drifts in the channel. 603.05 Placing Barbed and Tension Wire and Fabric 90 The bottom of the fabric shall be placed above the ground line as shown on the plans. Over irregular ground, a minimum of 1 in. and a maximum of 4 in. clearance will be allowed. All necessary excavation and backfilling required shall be in accordance with 201.03. The tension required to stretch the fabric and wire shall be applied by mechanical fence stretchers and with single wire st retchers designed and manufactured for the purpose, and in accordance with the fe nce manufacturer’s recommendations. All splices in the fabric and wire sha ll be securely made in accordance with the 100 best practice and the manufacturer’s recommendations, and by the use of tools designed for that purpose. Farm field fence shall be placed by fastening one end and then applying sufficient tension to remove all slack before making permanent attachments elsewhere. The line wires shall be fastened to end, corner, and pull posts by wrapping the wires around the posts and tying the wire back on itself with no less than 1 1/2 tightly wrapped twists. Tying shall be with tools designed for the purpose in accordance with the fence manufacturer’s recommendations. This same method shall be used in placing barbed or tension wire. Fence fabric shall be fastened to intermediate or line posts with at least 110 five wire ties. Barbed or tension wire shall be fastened in the same manner with one fastening device for each post.
The top and bottom tension wires of chain link fence shall be placed, stretched taut, and secured at the ends and to all posts before the fabric is placed. The ends of the fabric shall be secured by the use of stretcher-bars threaded through the loops of 603.05 500 the fabric and secured to the posts by means of clamps with bolts and nuts. The number of clamps shall be as indicated on the plans. The fabric shall be placed by securing one end and then applying tension to remove all slack before making attachments elsewhere. The fabric shall be fastened to the line posts and to the top and bottom 120 tension wires with tie wires spaced as shown on the plans. 603.06 Resetting Fence Resetting fence shall consist of the removal of existing fence within the specified limits and, if necessary, storing and resetting it in accordance with the plans, or as directed. Resetting fence shall be in accordance with 603.03, 603.04, and 603.05. Damaged or missing parts, in cluding posts shall be replaced.
603.07Method of Measurement
Fence and resetting fence will be measured by the linear foot for the type 130 specified. Measurement will be made along the top of the fence from outside to outside of end posts for each continuous run of fence. Gates will be measured as complete units of the size and type specified. 603.08 Basis of Payment The accepted quantities of fence and resetting fence will be paid for at the contract unit price per linear foot for the type specified, complete in place. Gates will be paid for at the contract unit price per each for fence gate, of the type and size specified, complete in place. 140
