Statement of Work August 06, 2018 Repair and Repave Price Park Campground Roads Loops B thru F Blue Ridge Parkway

PART 1 – GENERAL

1‐1 DESCRIPTION OF WORK

A. Julian Price Campground is adjacent to Price Lake and is a top destination for boating, hiking, fishing and more. The surrounding forest offers hemlock, white pine, oak, hickory and birch trees, along with a colorful assortment of wildflowers in the spring and an array of vivid orange and red foliage displays in autumn. The Blue Ridge Parkway (Parkway) is a scenic byway that follows the high crests of the central and southern Appalachians for 469 miles from Shenandoah National Park in Virginia to the Great Smoky Mountains National Park in North Carolina.

Canoe rentals are available at Price Lake, and other types of non‐motorized boats are permitted.

Fishing is also available at the lake, with a dock provided. Price Lake Trail offers a refreshing hike around the edge of the water, and the Boone Fork, Green Knob and Tanawha Trails are just a few of the trails that are conveniently accessed through the campground. Wildlife viewing is also popular as campers have a good chance of spotting bears, grouse, turkeys, owls, hawks and more. Julian Price Campground combines the traditional great outdoors experience with the modern conveniences of flush toilets and drinking water. Both RV and tent sites are available and provided picnic areas are perfect for barbecues or late‐night marshmallow roasting. Blowing Rock, North Carolina, located just 20 minutes away on the Blue Ridge Parkway, offers fine dining, shopping and more.

B. This Statement of Work (SOW) consists of repairing and repaving asphalt pavement roads, replacing pipe culverts with associated features, asphalt pavement widening, deep asphalt patching and installing paved waterways in Julian Price Campground Loops B through F (MP 297.0) of the Blue Ridge Parkway. Campground lane width is typically 11 feet +/‐.

C. Refer to Bid Sheet for required work items.

a. WEATHER‐ Sudden and dramatic changes in climate conditions are common. The Contractor must be prepared to alter work plans and provide protection for workers and equipment.

b. CLOSURES‐ Parkway officials may close portions of the Parkway at any time to protect visitors from hazardous conditions or to implement official duties of the Parkway.

c. REMOTENESS‐ Many portions of the Parkway are of extreme distance to typical services available in developed areas, including cellular, food, fuel, and emergency services. The Contractor must arrange and account for appropriate precautions and plans prior to bid submission.

d. RESOURCES‐ As a unit of the National Park System, the Blue Ridge Parkway is tasked to preserve unimpaired its natural and cultural resources and values. The Contractor must make every effort to ensure no impacts are made deleterious to these resources. It is expected that the project site and access areas will be minimally impacted only as absolutely necessary for the performance of the SOW requirements. Mitigations approved by the COR will be taken to restore pre‐existing conditions.

Blue Ridge Parkway

e. ROCK‐ The presence of various forms of rock is ubiquitous. The Parkway does not maintain data for construction purposes on the location or type of rock to be encountered by excavation or drilling activities. The contractor must verify and account for the extent, nature and impact to work activities of rock within the project site prior bid submission.

f. INVASIVE EXOTICS‐ To reduce the chance that harmful, non‐native plants or organisms will be transported from off‐parkway locations to the work site, the contractor, prior to entering the parkway, must clean all soils, roots, seeds, and other sources of plant parts and pathogens from any equipment used for the application of grasses and all heavy equipment, such as dump trucks, front end loader, and graders, which have previously been operating off the park.

g. WILDLIFE‐ All wildlife is protected within the park boundaries, and some species, which occur within the park, receive special State and Federal protection due to their rare, threatened or endangered status. Very few wildlife species present any danger to persons working within the park. Even species which have the potential to do harm to persons, can usually be avoided. Unless wildlife is presenting an immediate threat to persons, harassment or destruction of wildlife is prohibited.

Trash containers may not be available throughout the duration of the project so the Contractor shall dispose of food trash and debris off‐site at the end of each work day.

B. Final Cleanup: Remove all tools, equipment, surplus materials and rubbish from the site upon completion of the work. Restore, refinish or repair surfaces of existing facilities that are marred, scratched or damaged due to work of this contract, to match the original condition. Remove any grease, dirt, asphalt, stains or foreign material from the finished surfaces. Use cleaning materials recommended by the manufacturer of the surface to be cleaned. Sweep paved or concrete areas and rake grounds to remove all construction debris. At time of the final inspection, project site shall be thoroughly clean and ready for use. All nails shall be found, collected and removed during the final cleanup of the site and through the entirety of the project at the end of each work day.

2‐6 CLOSEOUT

A. Closeout Submittals: Upon completion of the work, the Contractor shall provide any final submittals called for in Section 1‐8.

B. Substantial Completion and Final Inspection: Submit written certification that project, or designated portion of the project, is substantially complete, and request in writing a final inspection. The NPS or designated representative will make an inspection within 10 days of receipt of request. When the NPS determines the work is substantially complete, a Letter of Substantial Completion will be issued along with a list of any deficiencies to be corrected before final acceptance. If the NPS determines the work is not substantially complete, the Contractor will be notified in writing, stating the reasons.

After completing the work, Contractor shall resubmit certification and request a new final inspection.
