11 1 <br /> WORK PLAN <br /> As shown on attached Boring Location Map, 12 geotechnical soil borings are proposed to the <br /> depth of 40 feet from the surface. The test boring will be advanced with a truck-mounted drill <br /> rig with 8 inches diameter auger. Boring will be advanced by using hollow stem augers. The <br /> boring will be drilled and capped in accordance with cement slurry. <br /> Selected samples will be obtained from 2.5-inch I.D. Modified California (MC) sampler and <br /> 1.4-inch I.D. Standard Penetration Test(SPT) sampler at various depths. The samplers will be <br /> driven into.subsurface soils under the impact of a .140-pound hammer having a free fall of 30 <br /> inches to the depth of 18 inches or practical refusal. The blow counts required to drive the <br /> sampler for every 6 inch will be recorded in field log. Pocket penetration tests will be <br /> performed on clay samples to evaluate the consistency. The boring will be drilled under the <br /> supervision of our engineer/geologist, who classified and continuous logged the soils <br /> encountered during drilling and supervised the collection of soil samples at various depth for <br /> visual examination and laboratory testing. The samples will be visually classified in the field <br /> and then transported to our laboratory for further evaluation and testing. <br />
