PART 3: EXECUTION

3.01 PREPARATION:

A. Clearing: Maximum mowed/clearing width is 6 ft on each side of the fence line. Provide minimum disturbance to existing grass and sod. Any blade work or other surface disturbance shall require prior approval.

3.02 INSTALLATION:

A. General: Set wood posts in dug or drilled holes. Drive steel posts. All line posts shall be steel and wood configuration as designated on the Work Data Sheet.

B. 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 within 6 inches of that 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 gradually and uniformly with soil around each post. Do not exceed 6 inch lifts during backfill. Compact backfill firmly from the bottom of the hole to the ground surface.

*Note: Milled wood posts shall be allowed to have an anchor plate or wood block attached to the bottom or a wood block attached to the side of the post base area to help anchor the post in place since it has no taper.

C. Driving Posts:

1. Wood Posts: Drive only when approved by the Contracting Officer to the depth shown on the Work Data Sheet. Predrill a 2 or 3 inch diameter hole as necessary if wood posts are to be driven. Wood posts shall be machine pointed if driven into the ground. Posts shall be driven 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 with cement grout or mortar.

D. Corner Panel and Stress Panel Assemblies: Set posts as specified, fabricate panels as shown on the drawings and indicated on the Work Data Sheet.

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 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. 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 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: Shall be double-looped and twisted tight with a stick. Leave one end of the stick long enough to fasten behind the horizontal brace to prevent wire from unwinding.

H. Wire Spacing: The wire spacing will be from the ground up. Bottom wire shall be smooth unless designated otherwise. Spacing for all projects is indicated on the Work Data Sheet.

I. Gates: Shall be installed according to the drawings, unless directed otherwise by the Contracting Officer. Contracting Officer will determine if stays shall be wood or wire.

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

K. Spiking: For spikes larger than 40d, predrill lead holes. 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. Deadman: Shall be installed at all minor depressions when the spacing between the bottom wire and the ground exceed 20 inches. Deadman can be rock weighing a minimum of 50 lbs or a 5 ½’ steel post driven straight into the ground a minimum of 4 ft. and parallel with the fence attached with additional wire of the same material as the bottom wire. See drawing 02834-1. Salvageable steel posts as approved and designated by the Contracting Officer shall be allowed as deadmen.

3.03 FENCE REMOVAL:

A. Shall include removal and disposal of clips, stays, wire, wood & steel posts, various panels, plus salvage of designated steel posts, wood posts, and gates as determined by the Contractor and as approved by the Contracting Officer. All removed material shall become the responsibility of the Contractor. Salvageable material shall be utilized as directed and approved by the Contracting Officer. Material not salvaged shall become the property of the Contractor. The Contractor shall be responsible to remove, dispose, and haul away all material as directed and approved by the Contracting Officer. Roll, secure wire, posts, and stock pile. No woven wire shall be returned to any of the fence permittees or other operators unless approval is given by the Contracting Officer. Wood and steel posts shall not be cut off at the ground level. Wood or steel posts that break off at the ground level shall be pulled or the stub shall be pushed below the ground surface. Any large holes or voids in the ground from pulled posts shall be covered or filled with appropriate sod or backfill to eliminate any safety hazards. Wood posts shall not be stockpiled and burned.

PART 4: MEASUREMENT AND PAYMENT

4.01 METHOD OF MEASUREMENT:

A. Units: The work described in this section will be measured for by the rod as measured along the ground surface next to the completed and removed fence including distance across gate openings, end, stress, and corner panels. The quantities of stress, and corner panels, single wood posts, 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. Deadman in the fence line are considered part of the fence construction and will not be paid as a separate item.
