This work consists of furnishing and installing fence, brace panels and gates; salvaging of existing fence; installation of temporary fence; and incidental work.
620.2MATERIALS
Right-of-way fence materials will conform to Section 920, except materials for Type I and Type IA temporary fence may consist of any approved new or used fencing material.
620.3CONSTRUCTION REQUIREMENTS
A.Right-of-Way Fence : Wood posts may be either handset or power driven. If hand set, the posts will be placed in the centers of the post holes and the backfill will be thoroughly tamped around the posts. The post holes will be a minimum of 2 inches larger in diameter than the nominal diameter of the post. If posts are sharpened, the posts will be sharpened on the small end to a blunt point approximately 3/4 inch wide prior to treatment. The fencing will be fastened to the sides of the posts facing the private property adjacent to the highway right-of-way. Fence on curves will be fastened to the side of the post, which will allow the wire to be pulled tight against the post. Woven wire fence fabric will be placed by securing or fastening one end and applying sufficient tension to remove all slack before making permanent attachments elsewhere. The fabric will be stretched until the tension curves in the line wires are approximately one half their original depths, keeping stay wires vertical. The bottom of the woven wire fabric will be placed a normal distance of 2 inches above the ground line. Over irregular ground a minimum clearance of 1 inch and a maximum clearance of 6 inches will be permitted for a distance not to exceed 8 feet. The Contractor will remove debris and perform necessary excavation and backfilling prior to installing the fence. Woven and barbed wire will be cut and wrapped at each panel encountered. In two post and three post brace panels, each line wire will be wrapped once around the last post and twisted back on itself with a minimum of four twists. If a three post panel has any angle to it, each line wire will be wrapped once around the middle post and twisted back on itself. Barbed wire will be fastened to brace panels by wrapping it twice around the last post and twisting it back on itself. Woven wire fabric splices will be made by the “wrap” splice method consisting of placing the two end vertical stay wires next to each other and twisting all of the free line wires four times around the line wires beyond these vertical stays. Barbed wire splice will be made by interlocking three barbs and twisting the loose ends four times around the main strands
