SOIL BORING DATA

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 the "Burmister's Method of Material Proportions". 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 said borings, or log thereof, he does so at his own risk. The geotechnical report, including soil boring drilling logs and data, is shown in the 2018 Schnabel Geotechnical Report at the end of the specifications. Soil borings shown in Appendix A, Laboratory Analysis is shown in Appendix B, and Beach Laboratory Analysis data is shown in Appendix C of the Geotechnical Report. All samples contained in the appendices at the end of the specifications 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: Matt McKeehan telephone 757-201-7172).

1.2 Sampling Method

All boring samples were obtained utilizing a vibracore sampler.

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 approximate and their respective location indicated.
