Lodgepole Fire Fence Rehab Charles M Russell National Wildlife Refuge

Garfield County, MT

Description of work: Provide all labor, materials, and equipment to repair or replace fence burned in the 2017 Lodgepole wildfire in accordance with attached specifications.

Project includes approximately 21 miles of burned fence. Currently, funds are available to cover approximately 14 miles of fence rehab. If funds become available for the remaining 7 miles, during the period of performance, they will be added by a negotiated modification.

Job conditions: Fence lines traverses terrain that may be wet, muddy or uneven. There are numerous drainages, both small and large, rises and falls, loose, rocky and compacted soils.

Location: Work is located on the Charles M Russell National Wildlife Refuge (CMR

NWR) in Garfield County, State of Montana. Prospective bidders may inspect the site by contacting the CMR NWR Sand Creek Field Station, 8407 Hwy 191 North, Roy, Montana, 59471. Telephone 406-464-5181. Work location is shown on attached map.

Contractors are urged to visit the work site and become familiar with existing conditions.

Failure of the contractor to ascertain the nature, location, and conditions which will affect the work will not relieve them from the responsibility for successfully performing the work without additional expense to the Government.

Removal of burned fence and structures: The contractor shall remove all fire damaged structures. This includes; wood post (remove or flush cut post at ground level), wire, wire clips, and staples. All removed materials will be properly and legally disposed of by the contractor.

Clearing: The contractor will, if necessary, clear fence lines of trees, brush, and other obstructions large enough to hinder construction operations. Fence lines may be cleared to a maximum of 4 feet on each side of the fence. On interior fence lines where the

Government owns the land on both sides, clearing may be done on either or both sides of the fence. On boundary fence lines where the Government owns land on only one side, clearing may only be done on the Government-owned side. Existing grass, sod, and other vegetation shall be disturbed as little as possible.

Construction Specifications:

Construction of new fence will be with 3 strands (Top 2 wires will be barbed wire and bottom wire will be barbless) in accordance with the specifications. Repairing fence will consist of replacing ALL wood structures with steel tubing, re-stretch and reattach wire to steel tubing.

General: T-Posts (Steel) shall not be used for end-panel, corner-panel, gate-panel, or stress-panel. Posts shall be installed plumb, to the designated depth, and the lateral alignment shall be within plus or minus ½ inch. T-Post spacing shall be 1 rod (16.5 feet) between posts. T-posts may only deviate 6 inches from the 1 rod spacing except

(due to the topography of the ground) when closer spacing is needed to attain specified wire heights. Drive T-Posts into the ground until the anchor plate is slightly below the ground surface.

Corner Panel, End Panel, and Stress Panel Assemblies: All structures shall be replaced and constructed with steel tubing.

Wire:

Barbwire fence (two upper wires) will be replaced with new wire if the galvanizing is burned off. Wire heights of 30 inches and 42 inches from the ground will be used.

Stretch tightly and securely attach to steel post or structures. Wire is properly stretched when it is springy to the touch. Terminate wire at each end post, gate post, corner post, or stress panel by wrapping around the post a minimum of two times and tie off by wrapping incoming wire a minimum of five times.

Smooth wire fence (bottom wire) will be replaced in its entirety and will be at a height of 18 inches. If any sections of fence have a bottom wire that is barbed, it will be removed and replaced with smooth wire.

Fence stays: shall be used and placed approximately halfway between line posts, and shall be replaced if damaged. Missing stays shall be added. Wire fence stays shall be used for intermediate gate stays.

Wire Gates: Replace wood gate sticks with steel tubing.

Panel or dead man at minor depression: Dead man shall be constructed of barbless wire bent in two and wound around the three wires in the fence and attached to a full-length steel post. The wire shall be wrapped around the steel post a minimum of 2 times, and then wrapped around itself a minimum of five times. The post shall be driven 4 feet underground at a 45 degree angle with 1-1/2 feet extended above ground level. In extreme conditions, two steel posts shall be used and shall be positioned opposite one another to form a 90 degree angle between the two posts for maximum holding power. Line post may not deviate more than 6 inches on line spacing, except closer when needed to achieve specified wire heights

All posts may not deviate more than 1 inch from plum or specified height above ground Wire spacing may not deviate more than 2 inches from that specified The center of no post shall be more than 3 inches out of alignment between quarter-mile stakes set by government Splicing – Use wrap or telephone-type splice using at least five complete turns in each direction. Do not pull wire around corners.

Deviations:

Approximate structures affected by fire:

99 corners (replace with steel tubing)

19 Drainages (repair to original condition)

66 End Braces (replace with steel tubing)

27 Wire Gates

29 Single Wood Post (replace with steel tubing)

82 Stress Panels (replace with steel tubing)
