Proposed Operations Service Center Proposal PR86053 <br /> Busch Road - Pleasanton, CA December 10, 1986 <br /> Page 2 <br /> <br /> PURPOSE AND SCOPE <br /> <br /> The purpose of our investigation would be to explore the surface <br /> and subsurface soil conditions in order to provide site <br /> preparation procedures, foundation design parameters and pavement <br /> design sections for the subject development. In order to <br /> accomplish this and satisfy the objectives set forth in your RFP, <br /> we propose the following: <br /> <br /> Field Exploration <br /> <br />Based on our present knowledge of the subsurface conditions in <br />the general area, we plan to drill a total of 10 borings in the <br />proposed building areas as shown on the attached Boring Plan. <br />These borings would be drilled 20 to 25 feet deep each. In <br />addition, a total of 5 shallow borings, 4 to 6 feet deep each, <br />would be drilled to assess the subgrade conditions in the paved <br />and walkway areas. The borings would be advanced using a truck- <br />mounted rotary drill rig. <br /> <br />The field exploration program would be performed under the <br />technical direction of our soils engineer, who would also <br />maintain a continuous log of the borings, obtain undisturbed and <br />bulk soil samples, observe groundwater (if encountered) and other <br />site conditions, and record sampler driving resistance. The <br />soils would be classified according to the Unified Soil <br />Classification System. <br /> <br />Laboratory Testing <br /> <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, expansion, soil corrosivity, compaction, and <br />R-value tests. <br /> <br />Geotechnical Evaluation & Report <br /> <br />Based on the results of our field work and laboratory testing, we <br />would perform engineering analyses to evaluate foundation and <br />pavement conditions. The results of these analyses would be the <br />basis for our conclusions and recommendations; these would be <br />summarized in a report containing the following: <br /> <br /> 1. Site plan showing boring locations; <br /> <br /> 2. Detailed logs of borings; <br /> <br /> 3. Depth to groundwater (if encountered); <br /> <br /> BSI< <br /> ~\~ .... <br /> <br /> <br />
