2612 S Griset PL <br />Santa Ana CA 92704 <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 brown clay per (ASTM D1557) <br />Boring #1 <br />Boring #2 <br />117.9 pcf @ 13.6% MC <br />113.2 pcf @ 12.8% MC <br />For compaction control during excavation and recompaction of the on-site soils use: <br />Boring #1 <br />Boring #2 <br />Direct Shear <br />106.11 pcf @ Optimum moisture <br />101.88 pcf @ Optimum moisture <br />The Shear values for the brown clay per (ASTM D3080) <br />Bearing Value <br />Peak Ultimate Angle <br />Boring #1 230 240 27° <br />Boring #2 310 315 18° <br />For design purposes 3100 psf <br />2 <br />2612 S Griset Pl Unit <br />#23/17/2025
