PART 3: EXECUTION

3.1 PREPARATION:

MELSTONE DAM FENCE 02834-5

A. Clearing: Maximum mowed/clearing width is 6 ft on each side of the fence line. Some tree removal will be required, as directed by the Government. Significant areas of removal will be shown on the Maps and Drawings. All tree removal shall be conducted from the government side of the fence. Some hand work may be required due to the ground cover or terrain. Provide minimum disturbance to existing grass and sod. Any blade work or other surface disturbance shall require prior approval from the Government.

3.2 INSTALLATION:

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

B. Setting Posts: Dig holes for setting wood posts to the depth as shown on the Drawings. Set posts plumb and to the spacing and grades as shown on the Drawings, unless staked otherwise. Space within 6 inches of the dimension shown on the Drawings. 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 block attached to the bottom or a wood block attached to the side of the post base area to anchor the post in place since it has no taper to properly hold it in place.

C. Driving Posts:

1. Wood Posts: Drive only when approved by the Government to the depth shown on the

Drawings. 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 of the T-post is slightly below the ground surface. Posts shall be driven plumb. When rock formations prevent driving remove anchor plate of the T-post 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 and Stress Panel Assemblies: Set posts as specified, fabricate panels as shown on the Drawings.

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 standard Drawings.

MELSTONE DAM FENCE 02834-6

F. Wire: Stretch tightly and staple to wood posts or securely attach to T-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 or post. The contractor shall ensure that one end of the post or stick is long enough to physically rest behind as well as being physically secured to the horizontal brace member to prevent wire from unwinding.

All brace wires that lie on the groundward side of all support structures shall not exceed an overall height of 6” above the existing ground surface. All brace wires shall have their own twist stick or post, unless otherwise approved by the Government.

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

I. Gates: Shall be installed according to the standard Drawings or the Government.

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. 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. resting on the ground or a 5-1/2 ft. steel post driven angled into the ground a minimum of 4 ft. parallel and in line with the fence attached with additional double twisted wire of the same material as the bottom wire. See drawing Deadman at Minor Depression. Salvageable steel posts as approved and designated by the Government shall be allowed as deadman.

3.3 FENCE REMOVAL:

A. Shall include removal and disposal of staples, clips, stays, wire, wood & steel posts, various panels, fence marking lathe, plus salvage of designated steel posts, wood posts, and gates as designated and determined by the Contractor and as approved by the Government. All removed material shall become the responsibility of the Contractor. Designated salvageable material shall be stockpiled, utilized as directed and approved by the Government. 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 Government. No woven wire shall be returned to any of the fence permittees or other operators unless approval is given by the Government. 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 6 inches 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 on federal land. All felled trees shall be piled on federal land until removal.
