<br />PUMP STATIONS #15 <br />SCOPE OF SERVICES <br /> <br />CITY OF REDWOOD CITY <br />August 23, 2005 <br /> <br />Phase C. <br /> <br />Preliminary Design Study <br /> <br />This phase includes a preliminary design layout and memorandum that will be the basis for the <br />development of the final design. The tasks include but are not limited to the following: <br /> <br />1. Review the existing pumping conditions using the 7.4 HP and 9.4 HP pumps. During a site <br />inspection pump data and pump cycle time measurements will be collected. This data, <br />along with running time measurements nom the City's historical records, will allow an <br />estimate of the performance of the existing pump. <br /> <br />2. Review wet well volume and pump cycle time with 20 HP pumps. Establish whether City <br />standard Flygt pump model CP3l53 will work. <br /> <br />3. Develop three pump station modification alternatives. Possible alternatives are a separate <br />valve vault with the wet and dry wells modified using the existing 48" RCP manways or <br />modifying the walls or a modified dry well with the valve vault on top of the existing wet <br />well. A preliminary cost estimate will be prepared for each alternative. <br /> <br />4. Provide concept for discharge pipe alignment. <br /> <br />5. Recommend coating material to rehabilitate the wet well. <br /> <br />Six (6) sets of preliminary design study will be presented to the City for review. One meeting is <br />scheduled with City staff after review of the preliminary design study submittal. The goal of the <br />scheduled meeting is to come to consensus on the design elements and layout and move directly <br />into the 65% design submittal. <br /> <br />Phase D. <br /> <br />Design Development <br /> <br />Task 1. Sixty-Five Percent (65%) Submittal <br /> <br />Prepare for review by City, sixty-five percent (65%) complete construction documents consisting <br />of drawings showing all plan views, profiles, cross-sections, general notes, detailing of major <br />components, construction notes, utility connection points, outline specification and other <br />documents, including, but not limited to, details, catalog cuts and product literature for all <br />products, and engineering calculations. <br /> <br />Six (6) sets of sixty-five percent (65%) plans, outline specifications, and Engineer's Estimate <br />will be presented to the City for 65% review submittal. A marked set will be returned along with <br />City staffs comments and/or request for clarifications to Nolte for revision. One meeting is <br />scheduled with the City staff after review of the 65% submittal. <br /> <br />Task 2.
