The blow count provides a measure of soil strength as it relates to soil's in situ consistency or <br /> condition. <br /> The samples were obtained from the borings generally at intervals not exceeding five feet. <br /> LABORATORY TESTING <br /> Classification <br /> Soils were visually classified according to the Unified Soil Classification System, as presented <br /> in the boring logs in Appendix A. Most of the laboratory testing program was designed to <br /> review classifications made in the field. <br /> Moisture/Density <br /> The field moisture contents and dry unit weights were determined for selected soil samples. <br /> The wet unit weight was determined in pounds per cubic foot, and the field moisture content <br /> was determined as a percentage of the dry weight. The results of these tests are presented on <br /> the boring logs in Appendix A. <br /> Sieve Analysis <br /> A grain size analysis and determination of the percentages of material passing the No. 200 <br /> sieve was conducted on three samples. The sieve analysis results are used as an aid in soil <br /> classification. The sieve analysis results are presented in Appendix A. <br /> CONCLUSIONS <br /> Based on the results of our geotechnical investigation including field reconnaissance, <br /> laboratory testing and engineering analysis of the subject site. It is our opinion that the <br /> proposed development is feasible from a geotechnical standpoint provided the <br /> recommendations contained in the following section are incorporated into the project plans <br /> and specifications. <br /> 1) The site is underlain with Brown Sandy Silt, to a depth of approximately 4 <br /> feet. Below this soil is a dense, Tan Sandy Silt. <br /> 2) These soils are not expansive. <br /> 3) The Potential for Liquefaction and/or seismic induced surface rupture is low. <br /> 4) Differential settlement should not be a problem. <br /> (4) <br />
