Title: Fence Installation at the High Plains Grasslands Research Station

Scope of Work: A total of approximately 19,400 feet (3.7 miles) of new 4-wire, wood post fence is needed to be installed at the USDA-Agricultural Research Service (USDA-ARS) High Plains Grasslands Research Station, near 8408 Hildreth Road, Cheyenne, WY. There are four sections of new fence to be installed, Section 1 West Side (1 mile); Section 2 North Side (0.86 mile); Section 3 East Side (1.23 mile) and Section 4 West fence (.59 mile), as shown on the attached diagrams. All materials (posts, wire, staples – see below for specs) will be provided by the USDA-ARS. Installation will be provided by the contractor. Removal of existing fence shall be done by the USDA-ARS.

The contractor is expected to install 14, 2 post-H-braces (terminal), 3, 2 post-H-brace (in-line), 3, 3 post H-braces, and 6 single in-line corner posts. In-line 2 post-H-braces or single corner posts (see maps) will be installed approximately every 1,320 feet (1/4 mile) on fence with all 4 wires tied off to facilitate pull of wire in opposite directions from the in-line H-brace or in-line single corner post.

For terminal 2 post H-braces (14 of these), the primary corner post in each of these braces will be a 7 inch minimum diameter post with length of 10 feet (120 inches). These posts need to be installed to a minimum of 60 inches, thereby leaving approximately 60 inches aboveground.

The secondary corner post in each of these braces will be a 6 inch diameter post with a length of 8 feet (96 inches). These posts need to be installed to a minimum of 40 inches, thereby leaving approximately 56 inches aboveground. H brace posts will be connected by a steel pipe (minimum 1.9 inch diameter and a minimum length of 96 inches). A diagonal wire (using #9 wire) will be wrapped around both posts, with it tied to the bottom of the corner on the H brace using a deadman and at top of the other post (see examples of H brace terminal end assembly).

For in-line H brace posts (3 of these), both posts will be a 6 inch minimum diameter post with a length of 8 feet (96 inches). These posts need to be installed to a minimum of 40 inches, thereby leaving approximately 56 inches aboveground. H brace posts will be connected by a steel pipe (minimum 1.9 inch diameter and a minimum length of 96 inches). Two diagonal wires (using #9 wire) will be wrapped around both posts (see examples of H brace in-line assembly).

Single in-line corner posts (6 of these) will be an 7 inch minimum diameter post with length of 10 feet (120 inches). These post need to be installed to a minimum of 60 inches, thereby leaving approximately 60 inches aboveground.

Line posts will be wood, minimum 4 inch diameter at top, pointed/capped/round and doweled, with a length of 7 feet (or 84 inches). Line posts will be installed every rod (16 feet), and to a minimum depth of 28 inches, thereby leaving approximately 56 inches aboveground.

Four strands of fence wire will be as follows, top 3 strands barbed wire (12 ½ gauge, Class I, 2pt, 4 inch spacing) and the 4th (bottom) strand being smooth (barbless) wire (12 ½ gauge, Class I). Each roll of barbed/barbless wire is approximately 1,320 feet (1/4 mile) in length. The smooth wire will be attached to wood line posts by barbed, galvanized staples (minimum length of 1.5 inches) at a minimum height of 16 inches from the ground. The 3 top strands of barbed wire will also be attached to wood line posts by barbed, galvanized staples (minimum length of 1.5 inches) at heights of approximately 28, 40 and 52 inches from the ground.

All sixteen foot tubular steel gates will be provided by the USDA-ARS and installed by USDA-ARS personnel.
