Mr. James P. Bane Proposal PR89011 <br /> Subsurface Investigation March 6 , 1989 <br /> Proposed State Farm Service Center Page 2 <br /> Yosemite Avenue - Manteca, California <br /> The field exploration program would be performed under the <br /> technical direction of our field engineer, who would also <br /> maintain a continuous log of the borings, obtain undisturbed and <br /> bulk soil samples, observe groundwater and other site conditions , j <br /> and record sampler driving resistance. The soils would be <br /> classified according to the Unified Soil Classification System- <br /> Laboratory Testing <br /> Laboratory tests would be performed on selected samples to <br /> evaluate their physical and engineering characteristics and to <br /> aid in the engineering analyses. The testing program may include <br /> shear and/or compression, consolidation, moisture/density, <br /> classification, and R-Value test. <br /> Engineering and Report <br /> Based on the results of our field work and laboratory testing, we <br /> would perform engineering analyses to evaluate soil parameters <br /> influencing site preparation and foundations. The results of <br /> these analyses would be the basis for our conclusions and <br /> recommendations. These would be summarized in a formal report <br /> containing the following: <br /> 1. Site plan showing boring locations; <br /> 2. Detailed logs of borings; <br /> 3 . Summary of laboratory test data; <br /> 4 . Discussion of overall surface and subsurface soil <br /> and water conditions (if encountered) ; <br /> 5. Recommendations as to suitable foundation type <br /> and depth for the proposed structure; <br /> 6 . Recommended allowable bearing pressures and <br /> anticipated total and differential settlements; <br /> 7 . Recommended coefficient of friction and passive <br /> pressure to resist lateral sliding of foundations; <br /> 8. Recommendations for concrete floor slab and base; <br /> 9. Suitability of local material for fill and <br /> structural backfill; <br /> 10. Import fill specifications; <br /> BSI, <br /> &:�,tir,c i,31i <br />
