� •�� <br /> • Preliminary Soils Recommendations: Prepare preliminary soil design parameters and <br /> recommendations for the proposed widening. <br /> • Prepare Geotechnical Desi� and Materials Report: Prepare detail report including <br /> desi� recommendations for pavement sections, subg� preparation for culver[s, <br /> information on g conditions, and other relevant geotechnical issues. <br /> • Discuss seismic considerations, evaluate the liquefaction potential and comment on the <br /> site soil conditions from this standpoint. Information related to Caltrans Seismic desi� <br /> criteria such as depth to rock like material and peak rock acceleration shall be provided. <br /> • Prepare the report documentin� the work performed, physical data acquired and <br /> geotechnical design recommendarions. <br /> � Using the general plan as a base map, prepare Soil Survey Sheets and Log of Test <br /> Borings for roadway and structures, respectively, in accordance with the Caltrans <br /> standards. <br /> b) Bridge Foundation Report <br /> • Research and Data Collection: Review of readily available published geologic and soil <br /> literature in the viciruty of the site including review of the as-built drawings and esisting <br /> LOTB. <br /> • Permits: W e will comply with the City and Caltrans Permit requirements. We will <br /> obtain necessary utility clearances for field exploration. <br /> � Field Exploration: For the proposed new ramp bridge structure, drill2 borings ranging in <br /> depth from 2�-30 meters in depth. The borin� locations will depend upon the available <br /> access and any boring data from previous studies. A truck mounted drill ri� is <br /> anticipated for this work. Some traffic control is assumed at this time in areas where <br /> necessary. <br /> • Classify and continuouslv loa subsurface soil conditions encountered in each test boring <br /> at the time of drilling. Obtain "relatively undisturbed" and bulk samples of substrata <br /> from test borings. The bonn�s will be drilled and capped in accordance with the permit <br /> requirements. <br /> • Laboratory Testing: Perform laboratory tests on representative soil samples such as <br /> moisture density, unconfined compression, gradation analyses, corrosion tests and <br /> Plasticity Index test, as necessary. <br /> • Soils !�nalysis/Evaluation: Perform engineering analyses to develop design <br /> recommendations for the proposed foundations and approaches. <br /> City of Be[mont — Rou�e 101/Ralsron Ave IC Ntodifications 07/06/00 <br /> Proposal — PS�cE <br /> 4 <br /> � <br />
