PART 3 – EXECUTION

3.01 PREPARATION

A. Clearing: Maximum clearing width is 6 feet on each side of the fence line. Provide minimum disturbance to existing grass and sod. Dispose of debris by scattering.

3.02 INSTALLATION AND REMOVAL

A. General: Drive/set steel posts for fence endpanels, cornerpanels, and stresspanel posts (Steel t-posts shall not be used for panels unless specified in drawings).

B. Driving/Setting Steel Posts: Drive or dig holes into the ground to the depth shown on the drawings. Set posts plumb and to the spacing shown on the drawings, unless staked otherwise. Holes shall provide adequate open space around the post so backfill can be tamped to the full depth around the post. Backfill gradually and uniformly with soil around each post. Compact backfill firmly from the bottom of the hole to the ground surface. Where existing soils are sandy and posts are loose and unstable, posts shall be set in concrete at depths indicated in specs and drawings. All posts shall be firmly set in place.

C. Driving T Posts: Drive into the ground to the depth shown on the drawings or until the anchor plate is completely below the ground surface. Posts shall be driven plumb. When rock formations prevent driving remove anchor plate and excavate or drill holes a minimum of 18 inches deep and slightly larger than the diameter of the post. Place posts in the holes and grout the post solidly in position with cement grout or mortar.

D. Corner panel, End Panel, Stress Panel/H Brace assemblies: Construct as shown on the drawings or as staked in the field. Rock jacks shall not be substituted for these items. Construct stress panels on crests of hills, and a maximum of 1,320 feet center-to-center for barbed wire sections. In addition, stress panels are required at points between which wire is to be stretched. Construct end panels at the end of fence runs, including at gates, cattleguards, and rock rim termination points unless shown otherwise on the drawings.

E. Figure Fours and Rock Jacks: May be used with Contracting Officer's permission. Figure fours shall be used in lieu of steel posts, and rock jacks in lieu of wood line posts, except that where a series of figure fours are required, a rock jack shall be substituted for every fifth figure four. Figure fours and rock jacks shall be constructed as shown on the drawings.

F. 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. The wire shall be free to move through the wire ties as it expands and contracts. Drive staples into wood until the staple meets the wire against the post, but not so tight as to crimp the wire or prevent movement of 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. Wrap wire around the post two times and tie off by wrapping around the incoming wire a minimum of four times.

G. Brace Wire: Double-loop and twist tight with rebar, partial t-post, or steel rod. For steel pipe panels, each wrap shall be looped once around the post (as shown in drawings).

H. Gates: Shall be installed according to the drawings and as recommended by the manufacturer when applicable.

I. Mechanical Gate Closers: Line up the latch with the gate. Adjust latch assembly after installation so that the latch does not bind, and the gate hangs properly.

J. Spiking: For spikes larger than 40d, predrilled lead holes shall be used. The hole diameter shall be three-fourths the diameter of the spike and drilled to a depth no greater than one-half the length of the spike.

3.03 EXPLOSIVES

A. Requirements: The use of explosives is prohibited.

PART 4 – MEASUREMENT AND PAYMENT

4.01 METHOD OF MEASUREMENT

The work described in this section will be measured and paid for by the rod for each type of fence as measured along the ground surface next to the completed fence, including distance across gate openings, end, stress, and corner panels; cattleguards and drainage crossings.

Note: Gates do not include adjacent end or corner panels, these are separate items.

4.02 BASIS OF PAYMENT

A. Payment: Prices and payment will be full compensation for the work described in this section. Payment will be made under:
