<br />Grace Le, Redwood City <br />Redwood Shores Levee Proposal <br />October 7, 2008 <br />Page 4 <br /> <br />IIII~~ <br /> <br />consider future settlement, or other levee closure related issues Also, we have not <br />included an environmental consultant or biologists on our team, because we believe it is <br />premature to do so without knowing what the construction will involve. <br /> <br />Task 1 Deliverables: <br />. Existing Conditions Summary based on Visual Observations <br />. Topographic Survey <br />. Preliminary Engineering Analysis Report <br /> <br />TASK 2: GEOTECHNICAL CONDITIONS SUMMARY <br /> <br />2.1 Investigate Geotechnical Con ditions <br /> <br />Data Review <br />This task involves a review of geotechnical reports to assess, at a "due-diligence" level, the <br />underlying soil conditions, ongoing settlement, and stability of levees. Data such as number, <br />location and depths of borings and cone penetrometer tests (CPTs), etc will be recorded. <br />ENGEO will meet with the City Engineer and Maintenance Department to discuss past levee <br />performance and future planned maintenance operations for the levee. <br /> <br />Preliminarv Analvses <br />ENGEO will review the existing subsurface data including boring logs and strength data, and <br />perform general seepage, settlement, and stability calculations based on two or three typical <br />sections. <br /> <br />Summarize Geotechnical Conditions <br />ENGEO will prepare a Technical Memorandum summarizing their work, which will be <br />appended to the Preliminary Engineering Analysis Report. <br /> <br />Task 2 Deliverables: <br />. Technical Memorandum Summarizing Geotechnical Conditions <br /> <br />FEE & SCHEDULE <br /> <br />An estimate of hours by task, and our standard Rate Schedule, is attached. We will invoice <br />monthly based on Time and Materials, up to the limit shown in the attached fee. <br /> <br />We understand that the City is anxious to obtain the Preliminary Engineering Assessment <br />(Task 1 deliverables) and believe that w e can provide the report within 4 weeks of receiving a <br />signed contract and notice to proceed. <br /> <br />The Task 2 deliverables will be provided 4 weeks after the Task 1 deliverable. <br /> <br />M:\2007 Proposa/sl07401 Redwood CityLevee CertIGLe-10-07-08.doc <br />
