Installation of new fence at the USDA-ARS, Central Plains Experimental Range, Nunn, CO April 1, 2021

A Base of approximately 18,514 feet (3.5 miles) of new 4-wire, wood post fence is needed to be installed at the USDA-Agricultural Research Service (USDA-ARS) Central Plains Experimental Range

(CPER), two miles east of the intersection of Weld Country Road 37 and Weld County Road 114

Nunn, CO. There are four (4) segments of new fence to be installed (please see attached files for fence map locations and specifics for each fence segment):

1) Fence 1: (section 29, east fence) for 1 mile (5,280 feet)

2) Fence 2: (section 29, pasture name 29-30, south fence) for 0.93 mile (4,899 feet)

3) Fence 3: (section 32W, east fence) for 1 mile (5,280 feet), and

4) Fence 4: (sections 32W, south fence) for 0.58 mile (3,055 feet).

Only wooden line posts and wire (both barbed and barbless) will be provided by the USDA-ARS. All other materials (including, but not limited to staples and steel pipe H-braces (see specs below), and installation will be provided by the contractor. Removal of existing fence shall be done by the

USDA-ARS.

The contractor is expected to install ten (10) 2 post-H-braces (terminal), seven (7) single in-line corner posts, and approximately eleven (11) deadmen.

For terminal 2 post H-braces (10 of these), both the primary and secondary corner posts in each of these braces will be 2 7/8 inch outside diameter (OD) steel posts with length of 10 feet (120 inches). These posts need to be pounded into the ground a minimum of 60 inches, thereby leaving approximately 60 inches aboveground. H brace posts (minimum 2 7/8 inch OD and minimum length of 120 inches (or 10 feet)) will be connected by a steel pipe sleeve (3 ½ inch OD and length

10 inches) and bolt (minimum ½ inch bolt). See pictures at end of attached file.

Single in-line corner posts (7 of these) will be a 2 7/8 inch OD 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.

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. Posts cannot be hammered in – all holes for wooden posts must be augered or dug.

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 2 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 2 inches) at heights of approximately 28, 40 and 52 inches from the ground.

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

USDA-ARS personnel.
