903.02 Materials.
Use m aterials for chain link fences, gates, posts and post foundations, hardware , and appurtenances that conform to SECTION M08. Chain Link Fence. For permanent and temporary chain link fencing, use gates, posts, fittings, and related hardware that conform to Subsection M08.02. For fittings and other hardware not specifically included in these specifications, use standard commercial grade. Split Rail Fence. Use materials for split rail wood fences, gates, posts, and all related hardware that conform to Subsections M08.04 and M08.06. Fence Post/Fabric Replacement. Use materials and finishes that match the existing fence’s original application.
903.03 Construction Methods.
General. Perform clearing as necessary to construct the fence to the required grade and alignment. At locations with small streams or drainage ditches where it is not practical to conform the fence to the general contour of the ground surface, span the opening below the fence with wire fastened to stakes of the length required. Tie new fence to the terminals of existing fences, and stake down the chain link fence at several points between posts. At each location where electric al transmission or distribution lines cross any fence type covered by this Specification, furnish and install a ground conforming to Section 9 of the National Electric Safety Code. Installing Posts. Set p osts in Class A concrete w hen the Contract requires that posts, braces , or anchors be imbedded in concrete, and install temporary guys or braces as required to support the posts in proper position until the concrete has set sufficiently to anchor the posts. Do not place materials on posts or place strain on guys and bracing that are set in concrete until directed by the Engineer. Extend concrete footings to the required depth and dimensions. Where rock is encountered within the required depth to which the post will be erected, drill a hole of a diameter slightly larger than the largest dimension of the post into the rock , and grout the post in. Place the regular dimensioned concrete footing between the top of the rock and required grade. Use hollow pipe and tube type post that is fitted with post tops. Ensure that the bases of the post tops have flanges that fit around the outside of the posts and are secured.

SECTION 903 — FENCES 900-11 Use tension wires in sections of chain link fence. Place the top and bottom tension wire, stretched taut and secured at ends, to all posts in a satisfactory manner before fabric is placed. Installing Fabric. Place the fabric on the outside of the fence. Splice the rolls of fabric together. At end, corner, or gate posts, slip the stretcher bar through the end picket of the fabric and the stretcher bar bands at the same time. Tighten t he bolts in the stretcher bar bands. Stretch the fence at intervals of 100 ft. Secure one end of the fabric and apply sufficient tension to remove all slack before making the subsequent attachments. Tie the fabric to the tension wire with fabric ties spaced not more than 24 in. apart. Attach the fabric to the line posts with fabric ties spaced not more than 14 in. apart. Place the topmost clip on the line post as near to the top of the fabric as possible and the lowest clip as near to the bottom of the fabric as possible. At terminal sections (end, corner , and pull) and gate posts, fasten the fabric stretcher bars and bands. Space the fastenings not more than 14 in. on center for terminal sections (end, corner , and pull) and gate posts. Place t he topmost band on these posts as near to the top of the fabric as possible and the lowest band as near to the bottom as possible. Before making a closure, fasten the other end of the run to the end, corner, or gate post as described previously. Use the following for t he operation of making a closure of a run. Clamp the stretching equipment on the ends of the fabric parallel to each other and approximately 5 ft apart when the tension is first applied. Continue the stretching until the slack has been removed from both sections of the fabric. If the ends overlap, cut the fabric to match. Join the ends by the insertion of a picket. Braces. When top rail is not used, place braces 12 in. down from the top of the terminal posts and extend from the terminal (end, corner, and pull) post and gate posts to the brace post. Fasten the braces to the post, and truss the braces from the brace post back to terminal post with round rod and turnbuckle. Gates. Place the lower hinge (ball and socket type) on top of the concrete in which the gate post is set. Set the sockets for the cone and foot bolt in concrete so that the plunger pin will fit perfectly in the socket when the gate is in a closed position. Erect the g ates to swing in the direction indicated and provide with gate stops. Ensure that all hardware is secured, properly adjusted, and left in perfect working order. Adjust hinges and diagonal bracing in gates so that gates will hang level. Existing Fence Connection. Where a new fence joins an existing fence, set the corner post with brace post at the junction and brace the corner posts . If the connection is made at other than the corner of the new fence, ensure that the last span of the old fence contains a brace span.
