PRELIMINARY GEOTECHNICAL INFORMATION <br />Page 2 <br />Earth Mechanics, Inc. <br />March 20, 2018 <br />Lowering the groundwater table locally, for a temporary period, to an elevation just below the <br />pile cap elevation may be required (to construct the pile caps). If CIDH piles are used for deep <br />foundations, pile construction will require the wet method (slurry) of construction or installing <br />temporary casing. Whether slurry or casing is used, groundwater will be expelled from each pile <br />hole due to slurry or concrete displacing the groundwater. The expelled groundwater will need <br />to be temporarily stored, tested for contaminants, and properly disposed. <br /> <br />
