Blue Ridge Parkway Rehabilitate Humpback Rocks Picnic Area

STATEMENT OF WORK (SOW)

I. PROJECT BACKGROUND

This project consists of the removal and replacement of 20 (with additional as price options) picnic tables and picnic grills along the Blue Ridge Parkway in the Humpback Area of the Ridge District in Virginia. The contractor will purchase the appropriate concrete tables and elevated picnic grills that meet the specifications, and the contractor will fabricate appropriate wood seats for the concrete picnic tables. The Humpback Rock picnic area has 98 picnic sites, of which 20 tables

(with wood benches) and picnic grills are to be replaced, three of those designated wheel chair accessible. This project also allows for price option to rehabilitate additional picnic sites at

Humpback Rocks Picnic Area, striping for van accessible parking space, sidewalk and ramp for that parking space, and a 120-linear-foot accessible path.

II. SCOPE

Contractors shall furnish all labor, supervision, equipment, materials, transportation, supplies

(unless specified elsewhere as Government-furnished), and incidentals required to accomplish specified work in compliance with the terms, specifications, and provisions of the contract. Work onsite is estimated to begin around June 1, 2023 will need to be completed before the summer season begins again on April 15, 2024.

Performance Period: June 1, 2023 to April 15, 2024

Project Location: This project is located in the Ridge District of the Blue Ridge Parkway.

The Humpback Rock Picnic Area is located in Virginia, near the northern most part of the Blue Ridge

Parkway near milepost 8.5.

III. GENERAL DESCRIPTION OF WORK:

A pre-bid site visit is strongly recommended. Contractor and NPS personnel will walk site and identify and stake out specific picnic sites, tables, grills, etc., COR will attach site visit notes with photos of staking, selected picnic areas, and notations.

Each picnic site is surfaced with gravel and features a picnic table and elevated cook grill.

Remove and replace picnic tables. Old picnic tables are buried in the ground and will need to be pulled/dug out, and some of the old tables to be removed also have asphalt around them or concrete around them. Contractor is responsible for disposal of old picnic tables and any removed asphalt or concrete, as well as created a compacted gravel based site to place the new universally accessible concrete picnic table onto.

Example picnic sites as they exist:

Figure: A concrete top picnic table with recycled plastic benches.

Figure 3: A metal grill at the picnic area.

Figure: Condition problems associated with some picnic tables include spalling concrete.

And examples of expectation of completed work:

Picnic table replacement:

• Demolition: Remove and dispose of old picnic table, and associated/connected asphalt/concrete/rebar anchors

• Picnic Table Site Preparation: Grading work and recompacting after the old picnic tables are removed, installation of pad and fill to be able to support the weight of the concrete table. Level site with existing grade, providing additional compactable structural surface material as necessary to return grade and make up the void from the removed picnic table footing volume. Non-ADA picnic sites should have a level compacted gravel area at least 8’x10’ with an approximate 2% grade for drainage, then taper beyond to blend with existing landscape. Water should not stand onsite.

• Contractor will need to procure new universally accessible concrete picnic tables with wood (locust or white oak) benches (Outdoor Rec Inc, MODEL#100FSS or similar, submit for government approval as technically acceptable prior to purchase).

• Contractor will need to supply and install 92-inch long and 3”x12” strait cut locust or white oak boards for bench seats for the picnic tables, as well as carriage bolts fasteners, sand or plane any rough surfaces that would interfere with use. Two benches for each table to be installed and secured to the rebar welded plate of the concrete table, installed to manufactures recommendations.

• Installations of new picnic tables: New picnic tables should be installed back in the same location and orientation; product is 1-piece cast in place and weight 1900 pounds. * Note when the Park placed similar tables, they utilized a 60’ telescopic forklift with straps to be able to place the picnic tables from the asphalt road/picnic area without driving on the sloped grassy landscape.

• * ADA picnic sites will include a 4” thick concrete walk and pad. For ADA picnic sites assume 500 square feet of concrete will be required on average per site, each end should be assessable with a 4 foot clearance around, centered on a 16’x 24’ pad with a 4’ clearance around to the campfire grill and a 5’ sidewalk to the site from the ADA parking spot(a and be places so there is room for wheelchair maneuvering and a hardened surface is required; sidewalks and pad not to except a 2% slope in any direction for drainage.

• Water should not stand onsite.

Cook Grill replacement:

• Demolition: Remove and dispose of cook grills, and associated/connected asphalt/concrete/rebar anchors

• Contractor will need to procure new ADA and non-ADA cook grills (may install all

ADA, but no fewer than three will be ADA) (Pilot Rock ASW-24 Series Accessible

Grills for accessible sites, N-24 Series Charcoal Grill for non-ADA sites, or similar, submit for government approval as technically acceptable prior to purchase).

• Cook Grill Site Preparation: Grading work and recompacting after the old cook grills are removed, installation of new post and grill in same position and to specifications with compacted level surface around new grill, and at least 4’ between the grill and any tree or the picnic table. Non-ADA picnic sites should have a level compacted gravel area at least

4’ radius around new grill with an approximate 2% grade for drainage, then taper beyond to blend with existing landscape. Water should not stand onsite.

Accessible Van Parking striping, one site:

• Stripe 96” minimum space, and 60” minimum access aisle

• Ensure curb ramp and sidewalk access to bathroom pathway from access aisle.

• Install van accessible parking sign and post.

Demolish dumpster blind and pad:

• Demolish and remove all material associated with dumpster pad and blind.

• Restore site to level, apply 1” topsoil to site, seed and straw area disturbed my demolition work.

Layout Concept:

Images below is meant to illustrate Accessible site layout and potential walkway, and not pad dimensions, this project will require larger pads for ADA sites then those show in sketches below:

5. Park-Specific Conditions and Limitations

a. The Blue Ridge Parkway is wholly located along the ridges of the Appalachian Mountain range in parts of Virginia and North Carolina. The following conditions may be applicable to work sites inside Parkway boundaries:

i. 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.

ii. 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.

iii. 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.

iv. 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.

v. 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.

vi. 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.

vii. 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.

b. Project-specific environmental compliance mitigations: The following items are required by the National Environmental Policy Act and National Historic Preservation Act as applied to this project and may be described further in other sections of this statement of work.

i. All debris shall be removed from the park for legal and proper disposal.

ii. Staging and parking for vehicles, equipment and materials shall be confined to paved areas. Other areas utilized shall be only as designated approved by the

COR.

iii. Store all temporary inorganic or construction and demolition materials in a gathered/piled manner that will readily accommodate removal, and will not create fluid or additional waste removal problems.

iv. No tree removal has been identified as part of this project. In order to protect rare species, if a tree should require removal, all appropriate time of year restrictions shall be observed and removal shall occur outside of these restrictions, please provide the COR with as much notice as possible if tree removal may be necessary.

v. All construction activities shall be performed in a manner having the least possible detrimental effect upon the surrounding terrain or vegetation.

VII. SAFETY

Safety plans to be submitted for review, a specific plan for the relocation and placement of the picnic tables will need to be submitted and approved before that work can begin.
