Specifications include, but are not limited to: All replacement fencing components shall be installed to the most current design standard and in accordance with the Specifications and applicable Standard and Construction Details. Any exceptions to this shall have prior approval from the Engineer. In addition, all materials are to be replaced with like materials. Construct the fence to follow the contour of the ground. Place the bottom of the fence fabric at least 1 in. (25 mm) from the ground surface, but no more than 6 in. (150 mm). Clear the fence line a maximum of 8 ft. (2.4 m) wide and grade where necessary to provide a neat appearance. When the ground profile in low areas changes abruptly, use longer posts to maintain the ground clearance. Stretch multiple strands of barbed wire on the posts with 6 in. (150 mm) or less vertical clearances between strands of barbed wire. Connect the existing cross fences to new fencing, except for obviously unserviceable fences.
