PART 3: EXECUTION
3.1 INSTALLATION
A. Drive steel fence posts into the ground to the depth shown on the Drawings or until the anchor plate is slightly below the ground surface. Posts shall be driven plumb. When rock formations prevent driving remove anchor plate and drill holes a minimum of 18 inches deep and slightly smaller than the diameter of the post. Drive posts solidly into the holes.
B. Wire: Stretch tightly and staple to wood posts or securely attach to steel posts with standard wire clips. Wire is properly stretched when it is springy to the touch. Drive staples into wood until the staple comes in contact with the wire against the post, but not so tight as to crimp the wire. Do not drive staples parallel to the grain of the wood. Terminate wire at each end post, gate post, corner post, or stress panel by wrapping wire around the post two times and tie off by uniformly wrapping the incoming wire a minimum of four times.
C. Brace Wires: All panels shall be wrapped with two complete wraps of barbless wire and twisted tight with a tensioning device (wood stay stick, rebar or digger link). Leave one end of the tensioning device long enough to fasten behind the horizontal brace to prevent wire from unwinding.
D. Corner Panel, Stress Panel, and End Panel Assemblies: Construct as shown on the Drawings or as staked in the field. Construct stress panels on crests of hills, and a maximum of 1320 feet center-to-center for barbed wire. In addition, stress panels are required at points between which wire is to be stretched. Construct end panels at the end of fence runs and on each side of a gate unless shown otherwise on the Maps or Drawings.
E. Rock Jacks: With the approval of the Contracting Officer, steel rock jacks may be used in lieu of steel end panels, corner panels, and stress panels where rock formations prevent dug holes. Rock jacks will be paid for at the same unit price as the substituted item. Construct as shown on the Drawings. Figure fours shall not be used in place of line posts.
F. Gates: Shall be installed according to the Work Data Sheet and the Drawings. Fulcrum-type gate openers shall be installed on all gates using 4 foot long wood stays, or as approved by the Contracting Officer. Wire Gates: Shall be constructed of smooth wire, wood stays, and wire stays. Gate should be constructed to a width of 14’ unless otherwise noted by flagged area at project site.
G. Wood Stay Installation: Shall be installed at the spacing and quantities as shown on the Work Data Sheet. Stays shall be secured with 1.75” staples. Drive staples into wood until the staple comes in contact with the wire against the stay, but not so tight as to crimp the wire.
H. Items or debris (including layout flags), not designated as salvage for return to the government, shall become the property of the Contractor. The Contractor is responsible for the disposal of materials in a legal manner and the payments of all disposal fees. Burning of removed materials is not permitted on the work site.
I. Steel Pipe Assemblies: Steel pipe panels shall be constructed in accordance with the Drawings and will include galvanized pipe caps on the tops of the structures. If loose soil conditions cause corner panels to lift when the fence wire is stretched, a steel post shall be driven parallel and adjacent to the corner pipe a minimum of 2'-6" deep and wired to the panels. When rock formations prevent driving pipe, drill holes 18 inches deep and the same diameter as the pipe. Drive pipe solidly into the holes.
4.1 METHOD OF MEASUREMENT
A. Units: The work described in this Section will be measured and paid for by the linear foot for each type of fence constructed or repaired as measured along the ground surface next to the completed fence or as measured with GPS as indicated in the Order, including distance across gate openings; end, stress, and corner panels; and drainage crossings. The quantities of end, stress, and corner panels, gates, rock cribs, and stiles to be paid for will be the actual number of these items. Note: Gates do not include adjacent end or corner panels. These are separate items.
4.2 BASIS OF PAYMENT
A. Payment: Prices and payment will be full compensation for the work described in this Section. Payment will be made under:
