BORING LOG NOTES <br />These notes and boring logs are intended for use with this geotechnical report for the <br />purposes and project described therein. The boring logs depict ORA's interpretation of <br />subsurface conditions at the location of the boring on the date noted. Subsurface <br />conditions may vary, and groundwater levels may change because of seasonal or <br />numerous other factors. Accordinc�ly, the boring logs should not be made a part of <br />construction plans or be used to define construction conditions. <br />The approximate locations of the borings are shown on the Site Plan. The borings were <br />located in the field by measuring from existing site features. <br />"Boring Size" refers the diameter and type of auger used. "HSA" denotes hollow-stem <br />auger. "SSA" denotes solid-stem auger. "BA" denotes bucket auger. <br />"Sample Nurtiber and Type" refers to the sampling method and equipment used during <br />exploration where: <br />�"AU" indicates a bulk sample taken from the ground surtace or from the auger flights. <br />•"SS" indicates split-spoon sampler with 1-3/8" inside diameter and 2" outside <br />diarr�eter. <br />"N-Value Blows/Foot" refers to the Standard Penetration Test which records number of <br />blows from a 140-pound hammer falling 30 inches required to advance a standard <br />sampler one-foot or a specified distance. Refusal is 50 blows for less than six inches or <br />25 blows without advancing the sampler. <br />"Water Content" refers to the moisture content of the soil expressed in percent by weight <br />of dry sample as determined in the laboratory. <br />"Qp" is an estimate of the unconfined compressive strength of the soil as determined with <br />a handheld, calibrated, spring-loaded penetrometer. <br />"Description and USCS Classification" refer to the materials encountered in the boring. <br />The descriptions and classifications are generally based on visual examination in the field <br />and laboratory. Where noted, laboratory tests were pertormed to determine the soil <br />classification. The terms and symbols used in the boring logs are in general accordance <br />with the Unified Soil Classification System. Laboratory tests are performed in general <br />accordance with applica��le procedures described by the American Society for Testing <br />and Materials. <br />"�" Indicates location of groundwater at the time noted. <br />A5 <br />l� 7 <br />
