The total linear footage of the interior fence line is approximately 1,800 ft. This includes divider fences between the elk exhibit and the alpaca exhibit. The replacement fence should be constructed of welded steel pipe fencing with 4” vertical posts and 2 3/8” horizontal top, bottom, and middle rails. Posts should be placed at intervals of 10’ with post bases set in concrete at a depth of 2 ½ ‘. 12 ½ gauge hi-tensile black woven wire should be stretched between the posts to a height of 8’. Rock or gravel should be placed under the bottom rail to prevent animals from tunneling under the fence. Installation of five 10’ swing gates and two 5’ swing gates should be included in the bid. Gate locations will be specified by the Zoo Director. All posts, rails, and gates should be painted black.
