<br />. <br /> <br />~ <br /> <br />" <br /> <br />f. Based upon the results of Task 15, the operations <br />program will be utiliz6d to determIne the average annual <br />energy, the firm energy, and the dependable capacity of <br />the selected Installed project capacIty for each water <br />rIghts sc~narIo, both wIth and wIthout the use of the <br />Placita Reservoir decree. This would be performed for <br />both the initial reservoir capacity and Its capacity <br />after 50 years of reservoir sedimentation. <br /> <br />g. Based upon the results of the operations study, <br />the incidental reduction in the peak flow of a 100-year <br />flood at the project site would be determined by routing <br />the hydrograph through the :eservoir under average <br />operating conditions. <br /> <br />Task 10 - Comparison of Alternative Arrangements - Dam and <br />, <br />Appurtenances <br /> <br />The purpose of this task is to establish the optimum <br />location, arrangement, and design of the dam and appurtenances. <br />This will be done by considering the geotechnical investigations, <br />site investigation, flood hydrology and sedimentation studies, <br />storable water analysis and operation studies. In carrying out <br />this work task, the Contractor shall: <br /> <br />a. Establish preliminary design criteria and parameters for <br />dam, spillways, outlet works, power plant and diversion. <br /> <br />b. Based on the preliminary operation studies for water <br />yield and power generation, the site inspection, and <br />the geotechnical investigations make a conceptual layout <br />of the project with an earth embankment based on the <br />maximum practical reservoir size. <br /> <br />c. E5tablish a basis for comparison of cost estimates <br />including cost level, date, construction perIod, annual <br />operating and maintenance costs, and interest rate, loan <br />term and other conditions to be assumed for financing, <br />all of which items shall be subject to the State's <br />approval. <br /> <br />d. Compare cost of concrete spillway arrangement such as <br />gravity, and slab and buttress, to determine most <br />ecomomic type of dam. <br /> <br />e. Compare costs of dam and spillway based on different <br />size"Location and arrangement of spillways, power <br />conduits, outlets and powerhouse, to optimIze facility <br />arrangements. <br /> <br />f. Analyze alternative diversion arrangements. <br /> <br />-10- <br />
