2) Ocracoke North end ferry bulk material storage yard

a. 35.189489 N -75.783677 W

3.0 BACKGROUND AND EXISTING CONDITIONS

The NPS maintains vehicle access ways to the National Seashore using a variety of materials for the surface. Shell materials must be conducive for passenger tire and off-road tire vehicles to drive over. Clam shells have been found as an aggregate material to be used for unpaved surfaces successfully allow passenger tires and off-road tire vehicles to drive over. Several types of shells are unsuitable due to their material properties. Oyster shells form sharp edges which can slash and cut tires, as well as visitor feet when walked upon. Scallop shells are thin, have little strength, break apart quickly, and provide no resiliency. Traditional gravel such as limestone or granite are not found locally, can be tracked onto the beaches, and are unsuitable for use on beach access roads. Suitable materials such as clam shells last approximately one year under normal traffic conditions and must be replenished regularly.

NC Highway 12 runs from Bodie Island south to Ocracoke Island. The Cape Point Campground located on Cape Hatteras National Seashore is accessed from Highway 12 onto Lighthouse Rd.

The Campground includes a parking lot located near the back of the campground with paved driveway and is a suitable place for shell storage (See Figure 1 below).

NC Dept of Transportation operates a ferry from Hatteras Island to Ocracoke Island. The north end of Ocracoke Island, near the ferry terminal, includes a dredge spoil and material storage

FY 24 Provide Clam Shell Materials Page 2 location (See Figure 2 below). The driveway into the material storage area is unpaved sandy surface unsuitable for vehicles which cannot travers off road.

4.0 STATEMENT OF TASKS

The contractor will provide all technical support, materials, tools, equipment, and manpower required to provide the NPS with the following:

Base BID: Provide 1200 cubic yards of clam shell material to Buxton to the Cape Point

Campground storage site. Take special note of the additional requirements below – receipts showing weights/volumes must be provided to the NPS and a copy kept for the Contractor’s records.

Material Requirements:

1) The clam shells must meet the following specifications:

a. The clam shells must be crushed and rolled to reduce edges. Whole shells should not account for more than 25% of the delivered material.

b. Scallops, cockle shells, whelks, and cone shells can be included but should not be more than 10% of the total shell volume.

c. Oyster shells may not be substituted.

Option 1: Provide 210 cubic yards of shell material to Ocracoke. Shell materials shall meet the same specification as the Base Bid.

Option 2: Provide 780 cubic yards to Cape Point Campground Storage Site. Shell materials shall meet the same specification as the Base Bid.

The NPS reserves the right to take samples of any or all deliveries to be tested for consistency and material distribution. The NPS reserves the right to withhold payment for any delivery that does not meet expectations as agreed upon between the NPS and contractor providing the material. If the material is deemed inadequate the NPS may reject the delivery and the contractor must provide additional material until the full amount of acceptable material is received. The contractor may obtain additional samples and test above the required number at his own expense to verify overall consistency of the deliveries.

ADDITIONAL REQUIREMENTS:

1) The vendor will be required to call the NPS point of contact (POC) for exact location on the day of delivery.

2) The Contractor must abide by the conditions listed in the Deliverables section of this scope of work.

3) The Contractor is responsible for all drivers and vehicles used for deliveries. These sites are considered off road and may require backing, turning, dumping, etc. on or near

4) The Contractor is required for scheduling deliveries to meet ferry routes to and from

Ocracoke Island. Contractor vehicles are authorized to utilize the priority lane for ferry routes between Hatteras Island and Ocracoke Island.

5) Each vehicle/truck providing a delivery must also provide a receipt showing the materials being delivered to include volume, weight, dimensions, etc.

6) The Contractor must keep his own record/receipts of delivery in order to request payment. Accumulated totals of each type of material must be provided to the POC prior to submitting an invoice for payment.
