Abstract: Large-scale beach restoration undertaken by the U.S. Army Corps of Engineers in Florida requires millions of cubic yards of beach quality sand. Exploration for these sand resources starts with analysis of the geologic setting, often with remote sensing tools, highlighting the possibility for relict sand deposits. Vibracore sampling and laboratory testing determine the quality of the sand deposits. Grain size comparisons with the native beach sand verify the compatibility of the sand for use in beach restoration. The geologic setting is used to determine the Government.s position for construction contract differing site conditions claims. The geotechnical aspects of beach restoration for Dade, Duval, Manatee and Pinellas County.s beach restoration project are reviewed.
