3. BACKGROUND AND EXISTING CONDITIONS

3.1. Asbestos and Lead Based Paint Testing is required prior to demolition.

3.1.1. A lead-based paint analysis was accomplished on the Water Tower, the Water

Storage Tank and all 3 water treatment site buildings on Loggerhead Lane. The results show no lead-based paint or asbestos on any of the structures and are attached below.

3.1.2. Asbestos testing was accomplished on the Water Tower, Water Plant, Water

Tank, Pump House Building, and the Coast Guard sewer system components. The results show no lead-based paint or asbestos on any of the structures and are attached below.

4. Cape Point Elevated Water Tower Site

4.1.1. The Elevated Water Tower has a total diameter of approximately 27’ and is approximately 85’ tall. The tower is made of steel metal. The top portion (sphere) is ¼” thick steel. The Plate Ring sections are 1” thick. The pedestal area of the tower has 4 section – two sections are 9/32” thick and the other two sections are

5/16” thick. The Base cone is 11/32” thick. The water tower is empty. Any remaining electrical lines coming to the tower must be disconnected and properly capped at least 3 feet from the structure and buried. The tower shall be demolished or dismantled in a “top down” order/method. Any non-mature pine trees may be cut or trimmed as needed to make space for the tower demolition. Do not cut down any mature trees, you may trim some as needed. The water tower rests on a 12 x 12 concrete pad that will also need to be removed. Inside the tower, there is a vault that is approximately 6’x8’ in the ground that shall be removed. There are 18 timber piles under the concrete pad that are equally spaced on a 24’ diameter circle, that support the tower, they shall be removed. After the site is clear of debris, the ground shall be leveled and reseeded.

The tank will need to be pumped out completely and all water removed from the site before demolition can begin on this structure. The tank extends below ground approximately 2 ft including its concrete foundation. Access to the tank is direct from Loggerhead Lane. Clearing brush around this structure shall be limited to 15 feet. This site, to include all structures and contents, will be demolished down to the soil and disposed offsite.

5.0 SCOPE OF WORK

This Statement of Work is not meant to be an all inclusive to do list for the project, but a list of the main items involved in the project. The contractor can use this list to assist him with the cost estimate for the project. The contractor will provide all technical support, materials, tools, equipment, and manpower to demolish all the structures and associated utilities or appurtenances in this Scope of Work. The contractor must abide by the specifications which are associated with this Scope of Work. The major project components are listed below but are not limited to the following:

5.1 Furnish all labor, material, and equipment necessary and required to perform the complete demolition, removal, and disposal of all structures identified in this scope of work. Any brush clearing to obtain access to any structures will be kept to a minimum and will be limited to 15 ft around the perimeter of any structure. Any brush removal, matting for equipment, or additional work to obtain safe access to the any structure scheduled for complete demolition is included within this project. All construction/demolition site debris must be removed. No burying or abandoning in place any portions of the tank, tower, pumphouse, lifts stations, shacks, or any associated building materials in this scope of work. Ground pipes must be removed to at least 3 feet below the surface.

5.2 No explosives may be used to demolish the tower or any other structures in the project. The contractor may use man lifts, telescopic booms, scaffolding, excavators, or other similar tools to remove the top of the tower and the large above ground tank.

Other alternative methods of demolition are possibly acceptable, and your proposed alternative methods shall be discussed clearly in the safety plan and proposal submittals.

5.3 Upon completion, all disturbed areas must be restored which may include but not limited to backfilling, leveling, and reseeding all disturbed areas. All debris on the ground must be picked up. No debris larger than a quarter should be left behind or on the ground. If paint chips fall off the tower or any structure during demolition, they must be cleaned up.

5.4 Provide hydroseeding to the disturbed areas, including and ruts or other disturbance created by construction work. Fill ruts or low areas with suitable material. Continue to water the grass until 75% of the area has seeded and growing.

a. Seed shall be suitable for the following:

i. Mostly shade location.

ii. Residential lawn

iii. Mowing operations with hand operated push or riding mowers

iv. Sandy soils

v. Septic Field coverage (roots that do not grow deeper than 24 inches)

vi. No weeds (dandelion, Bahia, pennywort)

vii. No exotic species.

Demolish Utility Infrastructure, Buxton NC Page 15

b. Hydroseed. Add a cover crop of grain rye at 30 lbs./acre. Rake broadcasted seed mix into the soil and saturate with water 2 – 3 times per day for 7 days, or until 75% of the area has seeds germinated and growing at least 1 inch high. Hydroseeded area may be observed for 7 days or until 75% of the area has growing seeds. If after 7 days, the area is less than 75% covered with new growth, overseed again and water 2-3 times per day until 75% of the ground is covered with growth.

5.5 Use this Seed Mix for restoration of demo location soil. Vegetation restoration of highly developed areas should be restored using the turf grasses already present as appropriate (such as “Outer Banks” Seed Mix)
