1834 W. 3 rd St. <br />Santa Ana CA 92703 <br />LABORATORY TESTING PROGRAMS <br />Samples of the in-situ soils recovered from the borings were used for our visual classification of the <br />material and further laboratory testing to obtain data for foundation design and site preparation <br />recommendations. <br />The laboratory testing consisted of performing classification, strength (shear), determining in-situ dry <br />density and moisture content; and determining the moisture-density relationship of major soils. <br />Descriptions of test procedures are included in the Appendix of this report. <br />The results of the testing are the basis for the conclusions and recommendations in the report. <br />SUMMARY OF SOIL AND DESIGN PROPERTIES <br />The following subsections and sections will present our detailed conclusions and recommendations for <br />the development of the site. <br />Basic Soil Properties <br />Maximum Density <br />The Maximum Density for the grayish brown silty sand per (ASTM D1557) <br />Boring #1 <br />Boring #2 <br />116.2 pcf@ <br />119.1 pcf@ <br />13.0% MC <br />10.8%MC <br />For compaction control during excavation and recompaction of the on-site soils use: <br />Direct Shear <br />Boring #1 <br />Boring #2 <br />114.2 pcf@ Optimum moisture <br />108.45 pcf@Optimum moisture <br />The Shear values for the grayish brown silty sand per (ASTM D3080) <br />Bearing Value <br />Boring #1 <br />Boring #2 <br />For design purposes <br />Peak <br />260 <br />250 <br />2900 psf <br />Ultimate Angle <br />160 28° <br />140 27° <br />2 <br />1834 W Third St & <br />#2,33/21/2025
