<br />Classify and continuously log subsurface soil conditions encountered <br />in each test boring at the time of drilling. Obtain "relatively <br />undisturbed" and bulk samples of substrata from test borings. The <br />borings will be drilled and capped in accordance with the permit <br />requirements. Generally the borings are required to be backfilled <br />with cement grout. <br /> <br />Task 3 <br /> <br />Laboratory Testing: Perform laboratory tests on representative soil <br />samples such as moisture density, direct shear, unconfined <br />compression, gradation analyses, R-value tests, corrosion tests and <br />Plasticity Index test, as necessary. <br /> <br />Task 4 <br /> <br />Soils Analysis/Evaluation: Perform engineering analyses to develop <br />design recommendations for the proposed pavement, embankment <br />slopes and retaining structures. Perform corrosion study of the <br />subsoils per Caltrans guidelines. <br /> <br />Task 5 <br /> <br />Preliminary Soils Recommendations: Prepare preliminary soil design <br />parameters and recommendations for the proposed widening. <br /> <br />Task 6 <br /> <br />Prepare Geotechnical Design Report: Prepare detail report including <br />design recommendations for pavement sections, sub grade <br />preparation for culverts, information on groundwater conditions, and <br />other relevant geotechnical issues. Since the project is within the <br />State right of way the report will be a Geotechnical DesignlMaterials <br />report format. Only one report is planned for the project. <br /> <br />Discuss seismic considerations, evaluate the liquefaction potential <br />and comment on the site soil conditions from this standpoint. <br />Information related to Caltrans Seismic design criteria such as depth <br />to rock like material and peak rock acceleration shall be provided. <br /> <br />Prepare the report documenting the work performed, physical data <br />acquired and geotechnical design recommendations. <br /> <br />Using the general plan as a base map, prepare Soil Survey Sheets and <br />Log of Test Borings for roadway and structures, respectively, in <br />accordance with the Caltrans standards. <br /> <br />Task 7 <br /> <br />Design Review/Consultation through final design. <br /> <br />Assist design team during Caltrans design review process. <br /> <br />City of Redwood City - Route 84 (Woodside Road) Widening <br />Proposal- PS&E <br /> <br />08/08/00 <br /> <br />6 of 1 0 <br /> <br />,."'-"""'--,..~"'" <br />
