ROBERTSON DRAW FENCE REPLACEMENT SOW-1

STATEMENT OF WORK (SOW)

PROJECT: The Bureau of Land Management (BLM) Billings Field Office (BiFO) located in Billings, MT has a need for new fence installation, fence removal and replacement, removal of existing brace structures, and installation of new steel braces in Carbon County nearest the Town of Belfry, Montana and the City of Red Lodge, Montana. More specifically, the project takes place near BLM roads located near Grove Creek Road and Meeteetse Trail Road. All work takes place in Section

(S) 25 & S26 of Township (T) 8S and Range (R) 20E; S18 of T8S and R21E; and S4, S5, S6, S8, S9, S15, and S17 of T9S and R21E. All fence work is on land owned by the BLM.

The project is divided into a base bid and three (3) Additive Alternates that will be awarded based on the availability of funds. The Government may elect to award the Base Bid and/or any combination of the option bids. The Base Bid and Additive Alternates are described as follows:

The Base Bid involves furnishing labor, tools, equipment, supplies, and materials to construct approximately 489 rods of new barbed 4-wire fence (3 barbed with bottom barbless wire) with all steel fence posts and braces, and including gates; to remove and dispose of approximately 268 rods of existing woven wire and barbed wire fence; and to replace approximately 268 rods of woven and barbed wire fence with new barbed 4-wire fence (3 barbed with bottom barbless wire) with all steel fence posts and braces, and including gates, per this SOW, the supplemental specifications, and as designated on the Construction Drawing Sheet 4 of 19: Base Bid – 1 – New Fence; and Sheet 5 of 19: Base Bid – 2 – Replace Fence. Contractor shall connect existing barbed wire fences to new structures as designated by the Contracting Officer Representative and per this SOW and the supplemental specifications.

Additive Alternate 1 involves furnishing labor, tools, equipment, supplies, and materials to remove and to replace existing wood braces with steel braces, and install new steel braces, on existing barbed wire fence lines as designated by the COR, as staked in the field, and as shown on the Construction Drawing Sheet 6 of 19: Add Alt 1 – 1 – Replace Fence.

Contractor shall connect existing barbed wire fence to new structures as designated by the Contracting Officer Representative and per this SOW and the supplemental specifications.

Sheet.

B. Driving Posts:

1. Steel Line Posts (t-post): Drive posts plumb, into the ground to the depth shown on the

Drawings, Work Data Sheet, or until the top of the anchor plate of the steel line post (t-post) is 1-inch below existing ground surface. When rock formations prevent driving, remove anchor plate of the line 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.

2. Steel Brace Posts: Posts shall be driven plumb, into the ground to the depth shown on the Drawings and Work Data Sheet.

C. Corner Panel, End Panel, and Stress Panel Assemblies: Set posts as specified. Fabricate panels as shown on the Drawings and indicated on the Work Data Sheet.

D. 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 or only with prior approval from the COR.

E. Wire: Stretch tightly and securely attach to steel line posts with standard wire clips. Wire is properly stretched when it is springy to the touch. Terminate wire at each steel end post, wood gate stay, steel corner post, or steel stress panel. Wrap wire around the post two (2) times and tie off by wrapping around the incoming wire a minimum of four (4) times.

F. 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-inches above the existing ground surface. All brace wires shall have their own twist stick or post, unless otherwise approved by the CO.

G. 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.

J. 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-feet steel post driven angled into the ground a minimum of 4-feet parallel and in line with the fence attached with additional double twisted wire of the same material as the bottom wire.
