634.01Description

This Section shall cover the work of furnishing and installing, complete in place, commercial chain-link fence on posts and frames with either standard ground mounting or mounted on structures (bridges, retaining walls, etc.) as required by the plans, at locations shown on the plans or designated, all in accordance with the details shown on the plans and these specifications. CHAIN LINK INDUSTRIAL FENCE 517

634.02Materials

All materials shall conform to the requirements of Division 800, Materials, and shall be in accordance with details shown on the plans. Special attention is directed to Section 871.

When the fence is to be installed on structures which cannot utilize the standard method provided by the regular fence drawings, the type of post installation, etc., will be shown on the plans. Requirements for such installations will be shown on the plans. All miscellaneous steel used in such installations or mounting assemblies shall be of ASTM A 36 steel or approved equal and galvanized in accordance with ASTM A 123, unless such is otherwise provided by the plans.

634.03Construction Requirements

All construction methods and equipment employed in the setting of fence shall be in accordance with requirements of the specifications of the manufacture of the fence materials being used and such that the resulting structure will provide the expected service and be durable and complete in every detail.

All brush, stumps, logs, large roots, humps of earth, boulders or debris which would interfere with proper construction of the fence in the required location and present a pleasing and acceptable profile along the tops of posts shall be removed before starting fencing operations. Sound standing trees in the fence line shall be removed or trimmed as directed to provide adequate working room. The clearing and/or grading of the fence line and the disposal of material removed shall be accomplished in such a way that trees and shrubs on the remainder of the right of way will not be damaged. Breaks in profile of the fence shall be spread over vertical curves of sufficient length to ensure a pleasing appearance.

Posts and anchorages shall be set at intervals shown on the plans or directed. The posts shall be set plumb and true in alignment on the side which the fabric is to be attached. All end and corner posts, brace posts, pull posts and gate posts shall be set in concrete in accordance with plan details. Line posts may be set in place by one of the following methods: (1) set in concrete in the same manner detailed in the plans for brace posts, (2) driven, provided soil conditions are suitable and full embedment depth is obtained. When posts are driven, methods shall be used to protect the posts from damage due to driving operations. Damaged posts shall be repaired as directed or removed and replaced without additional cost to the State, Regardless of the installation method used, a stable fence frame shall be obtained. Where unstable soil is encountered, the use of longer posts, concrete anchorage or other approved post stabilization methods shall be required. Where fence is over solid rock or other hard unyielding material is encountered, special treatment may be authorized. When installing fence through areas where other than ground installations are required, special attention shall be given to the attachment of the mounting assemblies to the structure. Anchor bolts, etc. shall be cast into structures wherever possible. Other types of attachments, if permitted by the plans, must be approved by the Engineer before use. In any event, anchorage must be so installed as to present a neat workmanlike appearance.

Chain link fence shall be stretched taut and securely fastened to each post by means of approved metal bands or No. 9 gage {3.75 mm} wire spaced not more than 12 inches {300 mm} apart on posts and not more than 15 inches {375 mm} apart on the rail. The method of attaching at end posts, gates, and corner posts shall be as shown on the plans. If barbed wire is specified on the plans, the barbed wire, barbed wire arms, and method of attachment shall be as shown on the plans. Wires shall be stretched taut and spaced as shown on the plans.

634.04Method of Measurement

The quantity of chain link fence of each separate height and variation shall be the accepted lengths, exclusive of gates, measured along the top rail overall in linear feet {meters} to the nearest foot {0.1 m}, complete in place. The quantity of gates shall be the actual accepted number of gates classified according to type and width of gates.
