The scope of this project is to install a 8’ H x 900’ L chain link fence enclosure. The chain link fence will include the following:

1) excavation and concrete,

2) corner posts and braces,

3) three double swing gates, 8’ H x 20’ W opening, including posts and hardware in concrete,

4) a latch will permit operation from both sides of the gate with a provision for padlocking, accessible from both sides of the gate,

5) post caps for each post; provide line post caps with loop to receive top rail,

6) rail and brace ends for the gate, corner, pull and end post,

7) top rail sleeves or round-steel tubing not less than 6-inches long,

8) rail clamps: line and corner boulevard clamps for connecting intermediate and bottom rails to posts,

9) tension and brace bands: pressed steel,

10) tension bars: steel, length not less than 2-inches shorter than the full height of chain-link fabric,

11) truss rod assemblies: steel, hot-dipped galvanized after threading rod and turnbuckle or other means of adjustment,

12) tie wires, clips and fasteners,

13) three strands of galvanized barbed wires, arms, with clips, slots, or other means for attaching strands of barbed wire.
