GEOTECHNICAL ENGINEERING STUDY Mr. Arthur Skotdal , c/o Dykeman Architects E-6225 July 27, 1993 Page 3 _. Groundwater No groundwater seepage was observed while drilling. Therefore, we do not anticipate _ groundwater levels wiil have a significant sffect on the proposed excavation. Dewatering should not be necessary before beginning the excavation. However, permanent post- construction groundwater control measures should be provided by providing drainage � behind all foundation watis. In addition, it should be noted that groundwater conditions are not static; thus, one may -� expect fluctuations in the level and flow depending on the season, amount of rainfall, � surface water runoff, and other factors. Generally, the water level and flow rate is highest in the wetter winter months (typically October through May). -� � Laboratorv Testina "i laboratory tests were conducted on several representative soil samples to verify or modify � the field soii classification of the units encountered and to evaluate the general physical properties and engineering characteristics of the soii encountered. Field visual � classifications of the encountered soiis were supplemented by grain size analyses on � representative samples. Moisture content tests were performed on all samples. The � results of laboratory tests performed on specific samples are provided either at the I appropriate sample depth on the individual borinfl logs or on a separate data sheet contained in Appen�iix B. It is important to note that these test results may not accurately � represent the overall in-situ soil conditions. Our geotechnical recommendations are based on our interpretation of these test results and their use in guiding our engineering judgement. ECI cannot be responsible for the interpretation of these data by others. IIn accordance with our Standard Fee Schedule and General Conditions, the soil samples for this project will be discarded after a period of fifteen days following completion of this Ireport unless we are otherwise directed in writing. � I j �i ( Eorth Consultants, Inc. r
