Mr, Robert L. Warnick <br />September 16, 1982 <br />Page 3 <br /> <br />,AMP DRESSER & MCKEE INC. <br /> <br />The preliminary thickness of the wall and floor sections will be determined <br />by water, soil and seismic loading conditions. The type of roof structure, <br />its thickness, and the spacings of the support columns will be determined <br />by loadings on the roof and seismic conditions. <br /> <br />Task 4 - Evaluate Each Concept <br /> <br />Preliminary construction costs and maintenance costs will be made for each <br />of the conceptual layeuts prepared in Task 3. The concepts will then be <br />evaluated relative to each other, considering reservoir type, construction <br />costs, maintenance costs, aesthetics, visual impacts, and other aspects. <br /> <br />Task 5 - Prepare Report <br /> <br />A brief report will be prepared that will describe CDM's work, the concep- <br />tual layouts and their evaluation. Based upon the evaluation process in <br />Task 4, a "best conceptual layout" will be recommended to the City. <br /> <br />Task 6 - Meet with the City <br /> <br />Upon completion of Task 5, meet with the City to describe and discuss all <br />conceptual layouts and the recommended layout. <br /> <br />Phase Two - Design <br /> <br />Task 7 - Prepare Preliminary Design <br /> <br />Based upon the recommended conceptual layout from Task 5, and upon approval <br />thereof by the City, expand upon the layout to produce a preliminary design <br />of the Foothill Reservoir. This preliminary design will include piping and <br />valving arrangements, reservoir dimensions, roof support systems, and other <br />features all in detail sufficient to arrive at a reliable preliminary cost <br />estimate of the completed works. Prepare a preliminary estimate of the <br />costs of construction. <br /> <br />Task 8 - Meet With the City <br /> <br />Meet with the City, explain the preliminary design, and discuss and resolve <br />any problems or constraints relating thereto. <br /> <br />Task 9 - Prepare Final Design <br /> <br />Following approval of the preliminary design by the City, the final design <br />to determine the structural requirements of the reservoir wall, roof, roof <br />support system, floor, and piping and valving will be completed. Consid- <br />eration will be given to the results for the geotechnical analysis from <br />Task 2. <br /> <br /> <br />
