II. STATEMENT OF SERVICES

1. Description of Work. The Contractor shall perform a total of 13 vibracore drill holes for this project. The locations of these borings and are shown in Figure 1 (Attached). The coordinates for these borings are given in Table 1 (NC Grid). In order to delineate the soil to be removed in the Corridor, the Contractor shall thoroughly communicate field findings from each vibracore drill hole to USACE within five calendar days of borehole completion, including all field documentation.

The Contractor shall perform sampling procedures on all borings in accordance with the paragraph “Vibracore Sampling”.

The Contractor shall deliver the completed vibracore sample tubes and the field drilling data to USACE at the USACE Snows Cut Facility, 304 Annie Dr., Snows Cut, NC, 28428. See Figure 2 for the location of the Snows Cut Facility.

2. Purpose. Vibracoring is necessary to determine the location of material suitable for beach placement and the material to be disposed of in the ODMDS. The sampling, testing, analysis and determination of soil characteristics shall be performed by the U.S. Army Corps of Engineers, Wilmington District personnel.

3. USACE Furnished Materials. A map of pre-determined boring locations is provided in Figure 1 (attached), and coordinates provided in Table 1.

4. Vibracore Sampling. Borings shall be performed within 20 feet of the locations provided by the USACE in Table 1.

At each boring location, real-time kinematic (RTK) Global Positioning System (GPS) surveying techniques shall be utilized to provide accuracies of 0.2 feet both vertically and horizontally. Borings will be designated as the following “MHCC-16-V-#”. The recovered vibracore sampling tubes shall be carefully transported to the Snows Cut USACE Facility along with field drill data.

It is noted that the proposed boring locations are in an area with strong currents and can have rough sea conditions. The vessel and drilling equipment used to perform this work must be capable of operating and successfully completing the vibracore drilling in these adverse conditions.
