SECTION C—STATEMENT OF WORK

SCOPE OF CONTRACT

The purpose of this IDIQ contract is to construct 5 aspen field fences to function as large ungulate exclosures in the Summit Mountain area and the Spring Valley area on the Kaibab National Forest. The fences will be constructed primarily of field fence material to a seven foot height at each location to exclude large ungulates from live aspen clones.

LOCATION OF PROJECTS

The first two aspen field fences items are east of Summit Mountain which is located south of Williams, AZ. One of the field fences is near McDougal Spring and is 3200 feet length and 7 acres. The other aspen field fence is on the east slopes of Summit Mountain and is 550 feet length and .3 acre. The other three aspen field fences are north of Parks, AZ. Two aspen field fence items are on the north slope of Wright Mountain and is 900 feet length and 1.3 acre, and 425 feet and .5 acre.. The other aspen field fence item is south of Quakie tank and is 400 feet length and .3 acre.

When completed to specifications the aspen field fences should remain in place for 20 years and be a sturdy barrier that would prevent big game, elk and deer, from damaging existing and future aspen regeneration. The work must be performed in compliance with the terms, specifications, and provisions of this contract; it includes furnishing transportation, equipment, construction operating supplies including materials and incidentals; labor and supervision necessary to complete the project. The source of the fence perimeter distances for Items 1-6 listed in this contract have been derived from a Garmin GPSmap 62 data collector set at NAD 83 datum. The perimeter distances listed in this contract represent three dimensional measurements which account for variations in elevation and slope.

TECHNICAL SPECIFICATIONS

1. SITE PREPARATION

Four of the field fence perimeters will be designated with red flagging and one with blue flagging, or other flagging color designated during contract prework. At several fence perimeter locations there may be standing live sapling trees, dead trees, or dead and down trees which may necessitate chain saw work and removal aside several feet of bucked up logs and slash. A construction corridor would have to be created wide enough to roll out and erect the field fence wire materials.

2. Fence Construction Items 1, 2, 3, 4, 5, 6

The fences shall be erected from a starting point designated and flagged as the fence gate location by the government. There will be two runs of field fence which will overlap and be attached with hog rings to create a fence not less than 7 foot height as measured from ground level to the top wire. Alternately, there may be erected 1 run of single panel field fence which would be 7 feet height or greater as measured from ground level to the top wire. The fence will be attached with fence clips to 10 foot steel ‘T’ posts, set 20 feet apart. The ‘T’ posts will be driven in the ground with a post pounder or by other means until the post spade is buried completely beneath the ground surface. A minimum of 6 fence clips shall attach the field fence to the t-posts.

A minimum of 4 hog rings shall connect overlaps of upper and lower field fence wire between line posts, or one hog ring every 5 feet.

3. Setting Posts

There shall be a t-post, tree bole, or wood post every 20’ feet along the fence perimeter. When t-posts are used for line posts, every seventh post shall be a live tree or construction of a wood post. Whenever possible, the contractor may utilize as line or corner posts healthy green trees (excluding aspen) which are 16” dbh or larger. In this instance, a 2x4 inch wood stay, 7-10 foot in length, shall be attached to the face of trees with nails 5 inches or longer. Next, the fence wire will be stapled or nailed to the 2x4. It may be necessary to drill holes in the 2x4 stays to prevent 2x4 wood splits from the nails. When a tree is used to begin or end a stretch of field fence, several 2x4 stays shall be nailed around the tree bole (Exhibit 13). The field fence wire shall be wrapped around the tree and tied off approximately 1 foot away from the tree bole to allow it to expand in growth for the lifetime of the fence. In some locations where there is uneven ground topography or unstable soil conditions it may be necessary to have closer steel post spacing to maintain fence specifications.

If a suitable tree is not available as a line or corner support, the contractor shall erect a fence support utilizing a wood post and wood supports. (Exhibit 7, 8, 9) The wood post shall have a 6 inch top, and shall be of good quality and treated with preservative (do not use posts treated with copper-type wood preservatives). Inferior grade wood posts with cracks along the length of the post will be unacceptable. All wood corner posts or wood line posts shall be set firmly, vertically into the ground at least 2 ½ feet below the ground surface. The top end of the wood brace shall be secured with barbless wire and nails to a groove cut near the top of the corner or line post, and when completed shall form an approximate 45 degree angle with the center post. The bottom end of the wood brace shall lay on a flat rock and be connected to the base of the corner or line post with two wraps of barbless or high tensile wire twisted tight. The resulting construction of the line post and the brace when completed should usually form a right triangle on level terrain. At each designated corner post construction two braces shall be used to support the center post. The horizontal angle between the bases of the corner brace construction shall not be greater than 90 degrees for sturdy field fence support. Any other prospective fence corner or line construction method or modification shall be first discussed with the COR.

4. Attaching Fencing To Posts

The field fence wire shall be pulled tightly between tie-off corners with a fence stretcher, come-along, small tractor, or any other device so that there is not any visible sag in the field fence panel. The field fence wire shall be placed on the outside of trees or wood posts for installation along curved sections. The field fence wire shall be attached to the wood posts but not the braces. If the field fence is stretched down into a drainage or over undulating ground surface, extra t-posts shall be used to reduce excess space between bottom of the fence and the ground. There shall not be any spaces greater than two inches from the bottom of the field fence wire to the ground level.

An alternative is to utilize anchor weights as in the illustration below. Anchor weights for holding down fence wires crossing drainages or depressions in this example shall weigh at least 50 pounds or be equivalent to a 1 cubic foot concrete block. They shall be attached with 9 gauge or heavier smooth wire

Any changes in fence line direction or method of construction must be approved by the COR. Approval from the COR must be received before a front end loader tractor or any other heavy machinery that might excessively impact the subsurface soil is utilized to stretch the fence or haul materials

5. Gates The fence gates shall be constructed at designated locations. The width of the fence gates should not be greater than 10 feet. If the fence gate width is wider than 10 feet, a t-post shall be pounded into the ground at the midpoint of the gate. There shall not be a gap greater than 3 inches between the ends of fence gate and its attachments to a tree bole or fence post. Any changes to fence gate location shall be approved by the COR. Whenever available, the fence gate shall be constructed between two live Ponderosa pine trees >16 inches at dbh (diameter breast height), or alternately, the gate shall be constructed utilizing one live Ponderosa pine tree and a fence end post assembly. Where suitable live tree are not available, two end fence brace supports and the gate shall be constructed using available field fence materials. (Exhibit 11, 12, 13)

Contractor Furnished Property

The Contractor shall provide all materials for fence construction at each project sites. The contractor shall not substitute for the listed materials any inferior quality of materials to facilitate cost or completion of the fence. Materials include but are not limited to:
