GEO-ETKA, INC. <br /> Job No: F-12136-24 <br />2 <br /> <br />Soil Condition <br /> <br />The on-site soil is composed of a layer of silty sand extending to the depth of the <br />borings 10 feet. Note that soil variations in soil type may occur between the borings. <br /> <br />For a detailed soil classification refer to logs of the borings, Plates “B-1” and “B-2”. <br /> <br />Ground water was not noted in either of the borings. <br /> <br />All of the dry, loose, soft soil or fill soil found, irrespective of depth or lateral extent, must <br />be removed to firm native soil and replaced as compacted soil tested to 90%. <br /> <br />Remedial grading is required in order to minimize the potential differential settlement <br />and to clear the demolition debris along with compacting the disturbed soil from the <br />demolition debris. <br /> <br /> <br /> <br />Investigation <br /> <br />The subsurface was explored by hand drilling 2 borings, 5 inches in diameter, to a depth <br />of 10 feet below the existing ground surface. The borings were placed in strategic <br />locations where the major structure is to be constructed in a manner to determine the <br />subsurface conditions. Approximate locations of the borings are shown on the attached <br />Plot Plan, Plate “A-2”. <br /> <br />All of the borings were logged by our soil’s technician. Samples of both undisturbed <br />and disturbed soils encountered were obtained for laboratory testing and observation. <br />Logs of the borings are shown on Plates “B-1” and “B-2”. <br /> <br />The soils are classified in accordance with the Unified Soil Classification System <br />described on an attached Plate. This Plate also shows the type of sampler used in <br />obtaining undisturbed samples. <br /> <br /> <br />Laboratory Testing <br /> <br />The field moisture content and dry densities of the soils encountered were determined <br />by performing tests on the undisturbed samples in accordance with the ASTM Test <br />Method D-2216. Direct shear tests were performed on selected, undisturbed samples of <br />the soils in order to determine the strengths and supporting capacities of the soils in <br />accordance with ASTM Test Method D-3080. Density and field moisture information is <br />useful as indicators of the nature and quality of the material. <br /> <br />The results of the tests are shown on the logs of the borings, Plates “B-1” and “B-2”. In <br />addition, the blow counts to attain these samples using hand sampling tools are also <br />noted for information. <br /> <br /> <br />2010 & 2012 N Bush Ave, <br />#100 and #1012/21/2025
