CHAIN LINK FENCES & GATES <br />Section 02444 <br />15-1207 <br />4. Double gates: Provide cane bolt and ground set keeper with locking device and <br />padlock eyes designed as integral part of latch, requiring one padlock for locking both <br />leaves. <br />J. Post caps: Cast or malleable iron ball or acorn shape; with opening for top rail. <br />K. Wire ties: For tying fabric to tension wires, use 11 ga. steel hog rings spaced 24" o.c.; for <br />tying fabric to posts, use 9 ga. steel wire spaced 12" o.c.; for tying fabric to rails and braces, <br />use 9 ga. steel wire spaced 24" o.c. These are minimums. Manufacturer's standard <br />procedure may require more ties. <br />L. Bands: Use 14 ga. x 1" wide steel bands spaced 15" o.c. for securing stretcher bars to end <br />and gate posts. Bands may be used in conjunction with special fitting for securing rails to end <br />and gate posts. Chamfer to ease projecting edges of bands. <br />M. Concrete: Portland cement, ASTM C150; aggregate, ASTM C33; clean water. Mix materials <br />to obtain low slump concrete with 28 day compressive strength of 3,000 psi. Maximum size <br />aggregate 1-1/2". Re -tempering not permitted. <br />PART 3 - EXECUTION <br />3.01 INSTALLATION <br />A. General: Execute work in accord with best trade practice for industrial fence installations. <br />Make welds neat and secure, grind off excess exposed metal. Securely set posts plumb in <br />alignment at proper depth and height, and rigid bracing where needed; install fabric under <br />tension and securely tie to posts, rails and braces. Gates shall move freely without sag. <br />B. Setting posts: Space posts as indicated (10 ft. o.c. max.). Pour and tamp concrete leaving <br />no voids. Check posts for vertical and top alignment and hold in position. Dome top of <br />concrete and trowel smooth to shed water away from post. Align posts in footings as follows: <br />Without Slats or Windscreen: <br />a. Line Posts to 8'-0" high max: 1'-0" diameter, 3'-3" min. embedment. <br />b. End, Corner & Pull Posts to 8'-0" high max: 1'-0" diameter, 4'-3" min. embedment. <br />C. Line Posts 8'-1" to 10'-0" high max: 1'-0" diameter, 3'-9" min. embedment. <br />d. End, Corner & Pull Posts 8'-1" to 10'-0" high max: 1'-6" dia., 5'-3" min. embed. <br />2. Gates (single leaf) <br />a. To 6 ft. wide: 12 inch diameter, 36 inch embedment. <br />Where posts occur adjacent to structures or other work where concrete foundations may <br />conflict with post footing, block out to allow post installation or use off -set post. Hold post 4 <br />inches clear from face of structure <br />C. Tension wire: Provide wire at bottom of fence fabric. Install taut, tying to each post with 6 ga. <br />wire. <br />D. Fabric: Leave about 1-1/2" between ground and bottom barbs. Pull fabric taut and tie to <br />4 <br />
