MEDORA, ND

Replace Wildlife Boundary Fence – North Unit

PROJECT SCOPE OF WORK

NATIONAL PARK SERVICE

6 August, 2021

SECTION 01 10 00

DIVISION 1 GENERAL REQUIREMENTS OF THE PROJECT FOR CONSTRUCTION

PART 1 – GENERAL

ITEM 1 - DESCRIPTION OF WORK

1.1 Background: The North Unit (24,000 acres) boundary fence is an essential component in effective natural resource management. The park must maintain its boundary fence in good condition to keep cattle from encroaching on park land which prevents resource damage, and to keep large park ungulates (bison, longhorn steer, and horses) contained and managed.

1.2 Work Covered by the Contract Documents:

A. Project Location: Theodore Roosevelt National Park, Watford City, ND. Located in western North Dakota. The National Park Service is charged with preserving and protecting the resources. In order to execute this charge, resource preservation and protection is a central consideration in performing the work of this project. Plan set THRO2021-02, sheet #1gives general location of the North Unit’s Zone 4 of the boundary fence.

B. Work consists of Furnishing labor, equipment, supplies, and materials, to remove and rebuild with new materials approximately 5.6 miles (29,902 ft) of wildlife woven wire fence, , steel posts (U-channel Design) at 16 foot spacing. See Fence Line Detail Map (Attachment C). The total linear footage excludes approximately 1,250 ft of fence that will be replaced by the North Dakota Department of Transportation (NDDOT) under a separate contract.

The NDDOT work is not expected to impact the work of this contract. All existing corners, panels, gates, wood and steel posts along the fence route on the location maps shall be replaced to meet the minimum specifics identified in this scope of work and shown in the attached design documents. Tie fence into existing badlands formations where topography is vertical and precludes a normal fence from being constructed Note: The fence route shown on the location map on the THRO2021-02 plan set (sheet #1). This map is intended to indicate the approximate location and general description of the work sites. Detailed features such as fence alignment, corners, and panels are not depicted. These features can more accurately be identified and assessed by visiting the site. Contractor shall install National Park Service provided boundary markers and shall be installed in sight distance of each other, to indicate National Park Service Boundary.

Contractor Site Access and use of equipment- Contractor will be allowed limited access to the fence on the park and private sides of the fence line. The North Unit’s Zone 4 is adjacent to public land that is managed by the National Forest Service. During the construction phase Contractors may use pickup trucks for daily access the job site . Work site access locations and routes are identified on the Fence line Access Routes maps (Attachment B). In addition to these routes the park will identify known cultural resources that must not be disturbed. As a general rule, rocks should not be piled nor otherwise used as part of fencing or disturbed where piles of rocks currently exist. Pick-ups with trailers may be used to stage materials and equipment Skid-steer and front end loaders may be used in conducting work along the fence line.

C. Storage & Staging Materials- The contractor is allowed to use the park’s mix pit area to store fence materials. The Mix Pit area location is identified on North Unit overview map (Attachment A).

D. All work will be performed under a single contract.

ITEM 2 - CONTRACTOR’S USE OF PREMISES
