A. General: Steel posts shall not be used for end-panel, corner-panel, gate-panel, or stress-panel posts. Set wood posts in dug or drilled holes unless written authorization is obtained for driving

02827-10 line posts. Drive steel posts. When treated members must be bored or cut during construction, thoroughly swab untreated surfaces with copper naphthenate.

B. Ratio of Steel Line Posts to Wood Posts: 4:1

C. Setting Posts: Dig holes for setting wood posts to the depth as shown on the Work 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.

D. Driving Posts:

1. Wood Posts: Drive to the depth shown on the Work Data Sheet. Wood posts to be driven shall have tapered end driven into ground. Drive posts plumb. Posts that are split, bent or broomed will not be accepted.

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.

E. 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.

F. 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.

G. 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 crosswise with the grain of the wood. The wire shall be free to move through the staples as it expands and contracts. 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.

H. 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.

I. Gates: Installed according to the Work Data Sheet, the drawings, and as recommended by the manufacturer when applicable.

J. 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.

02827-11

K. 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.

L. 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 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 on a lump sum basis.

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.
