<br />!"~~;,.,?~ <br />\,)...' v.",....... <br /> <br />. <br /> <br />Cost Estimates <br /> <br />Costs for dams and reservoirs, the diversion darl and for <br />conduits were obtained by computation of quantities and applying <br />unit costs, Powerplant and substation costs were obtained frOLl <br />curves) transmission line costs per mile were taken from estimating <br />data. Data from curves were compared with ex1sting installations <br />of silililar size. RegardJ.ess of the method used, 00_1' s were <br />prepared for all features. Advance prints of recent U.S.G.S. <br />napping on a 1 to 24,000 scale were very usefUL in roaking layouts <br />and obtaining quantities, profiles, and lengths. Exhibit 1A is <br />a schematic single-line diagram of the electrical transmission <br />system. Adjustments were made in cost estimates to the degree <br />that accessibility, altitude, climate, geology, hydrology, labor <br />supply, and sources of material deviate from normal conditions. <br />All costs were converted to J~ 1962 price levels. Costs for <br />recreation development were obtained from the NationaJ. Park <br />Service and the Bureau of Sport Fisheries and Wildlife. <br /> <br />Suuw:y of Construction Costs <br /> <br />. <br /> <br />Over-all costs charged to construction include the estimated <br />cost of construction in the field, a contingency factor, and allow- <br />ances for construction facilities, investigations, engineering, and <br />overhead expenses. The estimated construction cost as set forth in <br />the plan of development is $lll,l08,ooo including costs associated <br />with recreationaJ. development. V <br /> <br />O];leration, Maintenance and Replacement Costs <br /> <br />Costs chargeable to Operation, Maintenance and Replacement <br />were obtained from three sources. Those associated with irrigation <br />works were computed from data in the Reclamation Instructions, <br />Series 150, Part 153; Operation, Maintenance and Replacement costs <br />of powerplants and power lines were derived from Reclamation <br />Instructions, Series 580, Part 583. Operation, Maintenance and <br />Replacement costs for fish and w1ldlife and recreation were <br />estimated by the agency concerned. <br /> <br />Instructions used for determining replacement costs were <br />published in reports of J~ 1958, November 1960, and supplemented <br />by letter of J~ 12, 1960, entitled "Approximate Factors for <br />Computing Replacement Reserve Requirements--Missouri River Basin <br />Project." <br /> <br />Y Costs by feature appear in Table No. A-l. <br /> <br />. <br /> <br />9 <br />
