Data Sheet. Set posts plumb and to the spacing and grades as shown on the drawings, unless staked otherwise. Space holes within 6 inches of the dimension shown on the drawings or in the Work Data Sheet. Holes shall provide adequate open space around the post so backfill can be tamped the full depth around the post.

Backfill with soil around each post gradually and uniformly. Compact backfill firmly from the bottom of the hole to the ground surface.

C. Driving Posts:

1. Steel Tubular Post: Drive to the depth shown on the Work Data Sheet. Drive posts plumb. Posts that are split, bent or broomed will not be accepted. When rock formations prevent driving excavate or drill holes a minimum of 36 inches deep and slightly larger than the diameter of the post. Place posts in the holes and grout the post solidly in position.

02827-13

2. Steel Posts: Drive 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 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.

D. Corner Post, Gate Post, Corner Panel, Brace, End Panel, and Stress Panel 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, at points which wire is to be stretched, and a maximum of 1320 feet center-to-center.

Construct end panels at the end of fence runs unless shown otherwise on the drawings. Brace rails shall be nailed to the panel posts using two nails at each end of the rail.

E. Figure Fours and Rock Jacks: May be used in rock. Figure fours shall be used in lieu of steel posts, and rock jacks in lieu of wood line posts; except 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 securely attach to steel posts with standard wire clips. Wire is properly stretched when it is springy to the touch. 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 a stick. Leave one end of the stick long enough to fasten behind the horizontal brace to prevent wire from unwinding.

Fireproof Fencing Brace Tensioner Kit or equivalent is also acceptable.

H. Gates: Installed according to the Work Data Sheet, 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 1/2 the length of the spike.

K. Minor Depressions or Minor Drainage Crossings: Add additional steel posts and wire when space between bottom wire and ground exceeds 20 inches for barbed wire

02827-14 fence. Additional steel posts shall be set at the top and bottom of breaks or the centerline of the drainage depending on the size and shape of the drainages.

Additional wire shall start and end from the main fence.

4.1 METHOD OF MEASUREMENT

A. Units: The work described in this section will be measured and paid for by the foot of fence as measured along the ground surface next to the completed fence, including distance across gate openings, end panels, stress panels, corner panels, and drainage crossings. The quantities of end, stress, and corner panels, and gates 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.

B. No direct payment will be made for deadmen, minor depression crossings, or drainage crossings. The Contractor shall include consideration for these items in the bid price for other items of the contract.

C. Fence removal will be measured and paid for in Section 02827 – Fence Removal.
