General Information and Requirements

PART 2: PRODUCTS

2.1 CONTRACTOR FURNISHED MATERIALS (all quantities listed below are estimates. Contractor responsible for calculating quantities and providing all materials needed):

A. General: Submittals shall be according to General Information and Requirements. All new fencing materials (no modifications to the factory constructed panels will be allowed) shall be as follows:

Continuous Panel Fence (35 panels total), posts, mounting hardware, end caps, jump-out materials

1. Panels: Manufactured, unaltered unpainted panels, constructed with 1.25 inch 14-gauge pipe. Panels shall have five rails (top, bottom, and three evenly spaced mid-rails). Panels shall be 20 ft long with a total panel height of 48 inches. Rail spacing shall be even between all rails. Panels will include four vertical stays spaced so as when panels are coupled together, there will be 5-foot spacing between the stays.

2. Fencing will be mounted to 6-inch by 8 ft treated wood posts, set at ten-foot spacing to a minimum depth of 36 inches. Post will be set and tamped into the post holes. No driving of wood post will be accepted.

3. Factory mounting brackets shall be provided to attach every rail to each wood post.

4. Couplers/connectors shall be provided for every rail.

5. 5/16 inch x 3 inch galvanized hex-head lag or “Timberlock” screws shall be provided.

5. Thirty-eight 5/16-inch x 6-inch galvanized hex-head lag screws or “Timberlock”. Every cross support shall have two screws with appropriately sized pre-drilled pilot holes.

PART 3: EXECUTION

3.1 MOBILIZATION AND DEMOBILIZATION:

A. Summary: All preparatory costs, work, and operations, including those necessary for the movement of personnel, equipment, supplies and incidentals to and from the project site. Progress payments will be made as follows:

1. Mobilization: When 10% of the total original Contract amount is earned from other Bid Items, 50% of the bid amount for Mobilization and Demobilization will be paid.

2. Demobilization: Upon final inspection and acceptance by the Contracting Officer, the final 50% of the bid amount for Mobilization/Demobilization will be paid.

3.2 PREPARATION:

A. Clearing: Where vegetation clearing is necessary, the Contractor shall clear vegetation with bush-hog mower, chain saws, hand saws or similar, to provide a maximum open width of 10 feet along the new fence alignment. No soil disturbance / bucket work shall occur for line clearing. The absolute minimal amount necessary of soil disturbance / bucket work may occur to lessen grade changes on the upper and lower ends of the exclosure. Woody debris generated by hand clearing shall be placed directly outside the clearing limits, as directed by the Contracting Officer. After the construction of the fence, woody debris will be scattered across any visible OHV tires tracks left near the egress and ingress points in a manner that prevents the future use of this area by OHVs and to promote herbaceous recovery.

B. All Equipment used for fence construction shall be cleaned before it enters the project site to minimize the potential for noxious weeds to be introduced to the project area.

3.3 INSTALLATION:

A. Continuous Fence (see also photos):

1. Fence will be constructed generally as depicted in site map. Exact installation location (fence alignment) may be shifted to optimize placement for function and longevity. Estimated overall length is approximately 640 feet. Panels will be mounted on outside sides of wood posts using mounting brackets and lag screws. No lag screws may be placed in the tops/side of top of posts. The height of the top rail will not exceed 50 inches. The height of the bottom rail will be approximately 2 inches above the ground. Every rail will have a coupler. All corners or open panel ends will have factory end caps installed. Every rail at every post will have a bracket. Every bracket will be attached with two screws. All panels must be parallel to the terrain. At channel crossings panels may need to be installed high enough to allow adequate clearance to prevent debris catching on bottom rail during high flow events. Banks may be cut as needed to establish a functional grade for fence installation. Removed soils shall be spread so no piles remain.

2. Post holes shall be dug or drilled and shall provide adequate open space around the post so backfill can be tamped the full depth around the post. Set posts plumb and to the spacing and grades as shown on the drawings or described herein, unless staked otherwise. Backfill and tamp gradually and uniformly with soil around each post. Compact backfill firmly from the bottom of the hole to the ground surface. Post will not be driven into the ground.

3. Wood Posts: Wood posts will be spaced at 10-ft intervals. All posts will be buried no less than 36 inches. Posts shall be installed plumb and in a straight line along the alignment. Corners will be constructed to minimize or prevent rail ends from protruding to reduce hazards and livestock rubbing. Panel end caps will be installed in all “open” panel ends.

B. Wildlife Jump out Gate (see photos below, taken from Montana Fish, Wildlife & Parks “Landowner’s Guide to Wildlife Friendly Fences” Second edition, 2012): One ten-foot wide opening jump out gate will be installed in the north 1/3 of the long west side. One eight-foot wide opening jump-out will be installed in the approximate mid-point of the east side. Wood up-right posts will be buried at a depth of no less than 30 inches. The top rail of jump out gates will be no higher than 36 inches and the bottom rail no lower than 18 inches. There will be a 10-inch spacing between the bottom and top rail (see attached diagram, Figures 1 and 2 and following detailed description: Rails will be attached so that the bottom of the bottom rail sits 18 inches above the ground and the top of the bottom rail sits 22 inches above the ground. There will be a 10-inch spacing between the top of the bottom rail and the bottom of the top rail so that the bottom of the top rail sits 32 inches above the ground. The top of the top rail will sit 36 inches above the ground). The rails will rest on cross-members lag screwed onto the wood upright posts. Wood horizontal rails will be wired in place using heavy gauge tie-wire.

PART 4: MEASUREMENT AND PAYMENT

4.1 METHOD OF MEASUREMENT:

A. Units: The work described as mobilization/demobilization will be measured and paid for on a lump sum basis once you are mobilized onto the site (10%). The remainder of the price (90%) will be paid upon satisfactory completion of the project.

4.2 BASIS OF PAYMENT:

A. Payment: Prices and payment will be full compensation for the work described in this section. Payment will be made under:

1. Mobilization/demobilization 10% of contract price paid once on site.

2. Fence construction 90% Paid upon satisfactory completion of the project.

PART 5: OTHER TERMS AND CONDITIONS

5.1 TERMS AND CONDITIONS

A. All fence construction will cease when soils or road surfaces are saturated to a depth of 3 inches.

B. The BLM Project Lead and Contractor is responsible for informing all persons who are associated with the project that they will be subject to prosecution for knowingly disturbing archaeological sites or for collecting artifacts.

C. If any archaeological materials are discovered because of operations under this authorization, activity in the vicinity of the discovery will cease, and the Contracting Officer (CO) or Contracting Officer Representative (COR). Work may not resume at that location until approved by the CO. The Contractor will make every effort to protect the site from further impacts including looting, erosion, or other human or natural damage until BLM determines a treatment approach, and the treatment is completed. Unless previously determined in treatment plans or agreements, BLM will evaluate the cultural resources and, in consultation with the State Historic Preservation Office (SHPO), select the appropriate mitigation option within 48 hours of the discovery. The Contractor, under guidance of the BLM, will implement the mitigation in a timely manner. The process will be fully documented in reports, site forms, maps, drawings, and photographs. The BLM will forward documentation to the SHPO for review and concurrence.

D. Pursuant to 43 CFR 10.4(g), the Contractor must notify the CO or COR, by telephone and written confirmation, immediately upon the discovery of human remains, funerary items, sacred objects, or objects of cultural patrimony. Further, pursuant to 43 CFR 10.4(c) and (d), the Contractor must stop activities in the vicinity of the discovery and protect it for 30 days or until notified to proceed by the AO.

E. After the construction of the fence, any woody debris will be scattered across any visible OHV tires tracks left near the egress and ingress points in a manner that prevents the future use of this area by OHVs.

F. The Project Lead and/or Contractor is responsible for informing all persons who are associated with the project operations that they will be subject to prosecution for disturbing or collecting vertebrate or other scientifically important fossils, collecting large amounts of petrified wood (over 25 lbs./day, up to 250 lbs./year), or collecting fossils for commercial purpose on public lands.

G. If any paleontological resources are discovered as a result of operations under this authorization, the Project Lead and/or Contractor or any of his agents must stop work immediately at that site, immediately contact the BLM Paleontology Coordinator, and make every effort to protect the site from further impacts, including looting, erosion, or other human or natural damage. Work may not resume at that location until approved by the AO. The BLM or designated paleontologist will evaluate the discovery and take action to protect or remove the resource within 10 working days. Within 10 days, the Project Lead and/or Contractor will be allowed to continue construction through the site or will be given the choice of either (a) following the Paleontology Coordinator’s instructions for stabilizing the fossil resource in place and avoiding further disturbance to the fossil resource, or (b) following the Paleontology Coordinator’s instructions for mitigating impacts to the fossil resource prior to continuing construction through the project area.

H. Fence construction will take place between July 15 and October 15, 2021. This timeframe would avoid the greater sage-grouse and migratory bird nesting period and would allow for fence construction to be completed prior to big game rifle season.
