At this stage of the study, the communication and coordination with the <br />technical staff of the City and CWCB is essential to ensure that the <br />characteristics of each potential solution are adequately defined. MKE shall <br />prepare a brief interim report to document the background and development of <br />the alternatives for the project to this point. <br />The second phase of the alternative selection process under this task shall be <br />to compare and examine the alternatives in relation to the suitability for <br />project implementation. Reconnaissance -level cost estimates shall be made, <br />taking into account a wide range of contingencies. At this stage, the long- <br />term operation and maintenance advantages and disadvantages shall also be <br />reviewed. Judgmental values shall be applied in regard to assessing the dam's <br />safety and long -term liability, even though such factors may not be directly <br />quantifiable. <br />The City, CWCB, and the MKE project team s 1 conduct meetings which will <br />lead to a mutual agreement as to which a ive o carry forward on this <br />project. Sub- alternatives or integr the 1 tives may result from <br />this process. y <br />The final step in this task shall '� proceed to the feasibility design <br />phase, based on the results of the w lternative selection process outlined <br />above. Further detailed analyses shall be made regarding the structural and <br />hydraulic elements. Checks shall be made on earlier criteria and assumptions, <br />and the design shall be advanced to a feasibility level. Test results and <br />strength parameters shall be reviewed and additional stability analyses will <br />be performed as necessary. Spillway and dam modifications shall be compared <br />in greater detail and outlet works design refined. <br />Layouts and drawings shall be prepared to meet CWCB report standards. New <br />cost estimates shall be prepared based on a more detailed computation of <br />quantities and unit prices. <br />The plan developed under this task shall become the preferred plan for repair <br />and rehabilitation to be used in the remainder of the feasibility analysis for <br />this project. <br />
