The diver with ROV submersible will conduct ROV/Sonar survey along <br />fully submerged SE line including the inverted siphon portion in the middle third <br />section. If the condition is not adequately documented due to sediments and/or <br />water turbidity, divers would conduct tactile inspection and use a "clear water" box <br />over CCTV camera/digital still cameras to optimize. Removal of any sediment and <br />siphon dewatering will be provided as an optional service and is not included in the <br />scope. <br />Task 2.8: Shoring Methods Evaluation: Brierley Associates, a subconsultant to LEE & <br />RO, will evaluate and recommend appropriate shoring methods to suit soil conditions and <br />utility clearances, while protecting the underground utilities in place. It is noted that the <br />60" storm drain parallel with the existing sanitary sewer lines in Davis Street is backfilled, <br />at least in some areas, with pea gravel. <br />Task 2.9: Prepare Predesign Report: LEE & RO shall prepare a preliminary design <br />report summarizing the findings and recommendations of initial investigation. The <br />preliminary design report will define the basis of design and design criteria. A draft <br />predesign report will be submitted to the City for review and comments. Final report will <br />be prepared by incorporation the City's comments on the draft report.
