DIVISION 1 SHORT FORM GENERAL REQUIREMENTS

PART 1 – GENERAL

ITEM 1 - DESCRIPTION OF WORK

1.1 Sections of the existing boundary fence along the west rim of the park on Wetherill Mesa need to be replaced. It has deteriorated due to age, experiences reoccurring damage and failure due to constant pressure from livestock and native ungulates, and it is not an effective fence design to prevent livestock entry into the park or allow safe wildlife passage in and out of the park. The fence to be installed is a fixed knot woven wire fence design that is more durable and effective at reducing livestock access and allows for safe wildlife passage.

1.2 Work Covered by the Contract Documents:

A. Project Location: Mesa Verde National Park (MEVE)

1 Mesa Verde Mesa Verde, CO 81830 Wetherill Mesa – Montezuma County

B. Work consists of:

Work consists of: Removing 1.35 miles of existing boundary fence and installing 1.6 miles of new woven wire boundary fence. Removal of all old fence materials. Installation of one steel livestock gate and the repair/replacement of one “swing/flood gate” across a small wash.

Work site access may be reached by the main park road to Wetherill Mesa followed by a short hike (less than 1 kilometer). A helicopter may also be used if the contractor deems it necessary. The NPS personnel will not directly supervise the contractor during the performance of the work specified; however, the project’s COR or project inspector will inspect the work and field spot visits may occur at any time. Staging areas for installation equipment and fence materials will be designated and coordinated with the COR near the project area. The use of UTV’s is not authorized on this project.

See Division 05 – Fence Construction for additional details.

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

D. Contractor responsible for any and all required federal, state, county or city permits related to this project.

E. Period of performance: Work shall be completed within 365 days after the issuance of the Notice to Proceed.

a. Clarification: The Notice to Proceed will be issued with a period of performance that is all inclusive of supply lead times, material deliveries, decommissioning, installation, Page | 4 anticipated average weather days for location, final commissioning, and acceptance of completed work. The contractor will be expected to provide a project schedule with adequate critical path details to ensure all work is completed within the stated calendar days from issuance of the Notice to Proceed. If weather impacts project beyond typical average weather patterns, contractor shall provide documentation in request for additional days.

1.3 Existing Condition Protections:

The cultural and natural resources of MEVE are protected. The contractor is expected to mitigate, by all reasonable means available, any impacts to cultural and natural resources in the park. The contractor shall not collect or remove any cultural or natural resources within the park during the performance of this scope of services. At least one member of the contractor’s field crew must attend park backcountry training. There must be at least one contractor crew member on-site at all times that has attended the backcountry training. Training takes approximately 3 hours and will be provided free by park staff.

A. Preservation of Historical and Archeological Resources:

Cultural Resources Mitigations:

An archaeological survey will be conducted prior to the start of the project to identify cultural sites. If there are cultural sites along the fenceline, staging areas, or access routes, then avoidance and minimization measures will be put in place to protect them.

All archeological resources found within 5 meters (16 feet) of the fence line, staging areas, and temporary access routes will be documented and flagged for avoidance. H braces and T posts will not be placed within archeological site boundaries. If it is necessary to construct a segment of the fence across an archeological site, the contractor will modify the standard fence design to minimize ground disturbance. The contractor will not dig out any existing fence braces that are within an archaeological site.

Such fence braces will be cut flush with the ground and left in place, in order to minimize soil disturbance. An archeologist may be required to be on site during ground disturbing activities (e.g. digging/excavating etc). If any archeological materials are encountered, the contractor will stop construction at that location and contact the project COR or inspector immediately; construction cannot resume prior to COR approval.

B. Conservation of Natural Resources

Natural Resource Mitigations:

Prior to any necessary vegetation removal by the contractor (if construction occurs from April 1- August 1) Natural Resources staff will survey the area for active nests and any extant vegetation containing active bird nests (species protected by the Migratory Bird Treaty Act) will be flagged for avoidance. Prior to construction initiation, a representative from the natural resource office will inspect all proposed fence lines to identify any plant species of concern. Sensitive plants will be flagged and the contractor will be informed of the need for avoidance. Any deviation from the designated equipment and supply staging areas and fence construction area must be approved by the project COR or project inspector. Mitigations will be described to reduce the spread of noxious weeds to and from the work site. The contractor will coordinate with the COR before any shrubs or trees are removed if necessary.

DIVISION 05 – FENCE CONSTRUCTION

OLD FENCE REMOVAL

The contractor shall remove the existing 1.35 miles of fence at this site. The fence consists of h-braces, t-posts, 4 or 5 strand smooth and barb wire fence, and attachment hardware. Wooden posts may be flush cut. Some t-posts may require to be cut out of firm ground or rock. Any vegetation impeding the project will be removed (trimmed back) in coordination with the COR.

FENCE CONSTRUCTION

INSTALL H BRACES

H-braces will consist of either 5-inch wooden pressure-treated posts with wire and strainers, or metal posts and metal cross members. Metal posts will be used to facilitate h-brace installation into rocky substrate. IF WELDING H BRACES IN THE FIELD, APPROVAL

MUST BE OBTAINED FROM THE CHIEF RANGERS OFFICER FIRST DUE TO

POTENTIAL WILDFIRE CONDITIONS AND POTENTIAL. IN COORDINATION WITH THE

COR. H-braces will be placed between each 200 foot section of woven wire fence. H-braces may be placed closer (less than 200 feet) to adjust for terrain. H-braces also may be placed up to 300 feet apart and wire spliced together to adjust for terrain or where a gate or end-point is less than 300 feet from last h-brace. H-braces will include woven wire fence from the bottom of the cross member to within 18 inches of the ground to prevent livestock from crossing under the h-brace. The top of this woven wire shall not go above the bottom of the horizontal post. H-braces shall be placed to ensure the fence is straight and shall not deviate more than two feet from the boundary delineated by the COR. Portions of the fence line that need to deviate from the line due to rocky features shall be approved by the COR.

• Wooden Posts- Set each 5-inch wooden post 24-30 inches deep with a half 80-lb bag of concrete. The top of each h-brace will be 2-6 inches above the height of the woven wire. Five-inch diameter, six-foot long, wooden posts will be used as cross members with a top height of 42 inches. Support cross members by notching wooden posts and drilling 10 inch nail stake through the post into the cross member. Tighten the h-brace using two 12.5gauge high tensile wires tightened with an in-line strainer. The wires should wrap completely around the brace and meet at a mid-point between the opposite corners. Fence staples nailed diagonally will be used to secure the wire to the post.

• Metal posts- Steel posts (2-3/8 inch outside diameter, #10 gauge) can be used where the ground is composed of rock and too hard to dig wooden posts into. Metal posts will be set at least 12 inches deep. These posts will be installed into drilled holes and concrete will be used to fill any gaps in the drilled holes to ensure a tight pipe fit.

Angle iron or other alternative materials may be available for H-braces in these rocky areas if approved by the project manager. Again, woven wire fence will be used to fill the gap below the cross member to 18 inches above the ground. The dimension specs of the metal braces will follow the above specs for the wooden h-braces.

Page | 16

INSTALL WOVEN FENCE (SEE APPENDIX C FOR DETAILS)

7-foot t-posts and 8-foot #23 u-channel posts will be installed every 12 feet along the fence line. One u-channel post will be installed alternately for every two t-posts. Where the ground is too rocky to pound in posts, holes will need to be drilled and t-posts installed. U-channels do not need to be installed in rocky terrain where t-posts can be drilled in. T-posts and u-channel posts will be driven so no more than 6 inches of post is above the top of the woven wire, unless rock impedes further pounding. T-posts will be driven so the top of the cleat is below the surface of the ground.

The fence shall be straight and shall not deviate more than two feet from the boundary delineated by the COR. Portions of the fence line that need to deviate from the line due to rocky features must be approved by the COR.

Woven wire shall be high-tensile and fixed knot. It will be 48 inches high with 13 horizontal wires, 3 inches between vertical wires, and graduated horizontal wire spacing from 3 inches to 6 inches.

The woven wire fence will be installed so the graduated horizontal spacing is installed with the 6 inch mesh at the bottom and the 3 inch mesh at the top. The wire will be hung so that it is on the outside of the posts and h-braces.

The bottom of the fence at the posts will be 18 inches (no more than 22 inches and no less than 12 inches where ground is uneven) above ground to facilitate movement of wildlife under the fence. Where the bottom of the fence is above 22 inches due to uneven terrain, additional fencing, either woven wire or 12-guage double-strand wire, shall be used to fill in the bottom of the fence to keep it below 22 inches. The total fence height will be 66 inches. If double-strand wire is used to fill the gap, fence stays will be skewered into the woven wire and double-strand wire to reduce the double-wire from flexing up.

Woven wire will be attached to the h-brace posts using fence staples nailed diagonally and wired back on itself with the wire end wrapping at least 360 degrees. Woven wire will be attached to metal h-brace posts by wiring it back on itself with the wire end wrapping at least 360 degrees.
