SOIL BORING DATA

02/16

PART 1 GENERAL

1.1 Soil Classification

The soil was visually classified in the field according to the "Unified Soil Classification System" and described utilizing ASTM D 2488 Standard Practice for Description and Identification of Soils (Visual-Manual Procedure). While it is believed that borings accurately indicate subsurface conditions for boring locations on the date taken, the Government assumes no responsibility for actual conditions which may be encountered in execution of Contract. Should the Contractor rely, for any purpose, upon the accuracy or completeness of soil borings, or boring logs thereof, he does so at his own risk. The geotechnical report, including soil boring drilling logs and data are provided with the design package.

All samples contained at the end of this SECTION were obtained on various dates as designated on the respective boring. Geotechnical analysis data is available for review at Norfolk District, 803 Front Street, Norfolk, VA 23510 (Attention: Jane Bolton, telephone 757-201-7123).

1.2 Sampling Method

Cone Penetration Testing (CPT) was completed at three locations proximate to the proposed structure in accordance with ASTM D 5778. Cone resistance, friction resistance and pore pressure, among other data sets, were recorded at approximate five centimeter intervals. CPT data is available for review in the Geotechnical report located in ATTACHMENT 1:

Geotechnical Report. Additionally, soil samples were collected at depths ranging from about three to five below the mudline at two locations using a vibracore sampler until the sampler could not be advanced due to encountering denser soils. The CPT rig was also used to direct push tube samples to recover soils for visual classification and laboratory testing at one location to a depth of about 30 feet.

1.3 Soil Consistency Determination

Estimated consistencies (med. stiff, soft, etc.) are from Terzaghi & Peck "Soil Mechanics in Engineering Practice".

1.4 Boring Elevations and Locations

All boring elevations and locations are approximated. Boring logs are shown at the end of this section.
