About this file
This is a site characterization report (Appendix G) related to the Craney Island Eastward Expansion (CIEE) Pre-Dredging Phase 1C project. As an appendix document, it likely contains technical data and analysis about the site conditions but does not directly specify required products or services for the contract opportunity.
The associated contract opportunity itself involves new work dredging at the CIEE southeastern cell, with required depths of -41 feet MLLW for the main dike footprint and -25 feet MLLW for central/southern access channels, plus 2 feet of allowable over-depth dredging. The work is being conducted by the US Army Corps of Engineers Norfolk District and includes removing approximately 3 million cubic yards of material to be placed at the Norfolk Ocean Disposal Site (NODS), requiring EPA Section 103 concurrence. The contractor must handle dredging, material transport via ocean-going barges, NODS placement, and coordination with Port of Virginia maritime traffic.

APPENDIX E
1983-1985 VIBRACORES
Virginia Port Authority November 9, 2009 (Project No. 3582.006)
INTRODUCTION
This appendix includes data from vibracore sampling performed by Ocean Seismic and Survey, Inc. of Norwood, New Jersey and Exploratory Marine, Inc. (Exmar), of Virginia Beach, Virginia under the supervision of the United States Army Corps of Engineers, Norfolk District. A total of 45 vibracores were conducted within the potential sand resource area of Atlantic Ocean Channel in May of 1983 and July 1985. Geotechnical exploration logs and laboratory test data were obtained from Appendix C, Volume 4 of the report, “Geology and Soils, Subsurface Investigation, Atlantic Ocean Channel, Norfolk Harbor and Channels, Virginia,” June 1986, prepared by the United States Army Corps of Engineers Norfolk District.
Vibracore penetration logs with core descriptions, penetration rates, and laboratory test results are presented in this appendix in the original format of the 1986 USACE report.
Available laboratory test data and grain size curves are also presented in Appendix E in the original format of the 1986 USACE report and include data from all 45 vibracore explorations conducted during the marine drilling programs of 1983 and 1985. The laboratory test data summary table contains soil sample numbers, depth intervals, and laboratory soil classifications as well as the laboratory results for fines content, Atterberg limits, specific gravity, natural water content, natural dry density, and shear strength.
For clarity purposes, the exploration identification nomenclature from the original report has been standardized in this report. For our standardized exploration identifiers, we have retained the original exploration number (e.g. 194), but have altered the prefix to include the year of the exploration and the type of exploration (e.g. 85V-194), where “V” represents a vibracore exploration. The logs presented in this appendix contain a note that indicates the standardized exploration identification number that has been applied to each exploration and is used throughout this report, while Table E-1, along with charts and figures presented in this report use Fugro’s standardized nomenclature.
