� . . � - Appendix I private landowners, etc.) and will obtain from the Client information on water require- ments and possible cost sharing relationships with the villages of Argenta and Oreana. Pipeline routing alternatives will be reviewed with the Client to establish up to two routing plans to be used for costing. Harza will prepare report-quality exhibits of these alternatives based on USGS topographic maps. Subtask C.2 - Easement and Right-of-Way Requirements Harza's project team will offer technical advice to the Client's legal and real estate staff to determine the costs of obtaining rights-of-way, to advise on procedures to obtain easements and to develop pipeline routes that minimize both the costs and the delays anticipated in resolving property rights issues. To do this Harza will develop a list of easements to be acquired for proposed routes for purposes of cost appraisal. Costs of easements, specialty fees, and land acquisition will be estimated by Blank, Wesselink, Cook & Associates (BWC) as a subcontractor to Harza. Subtask C.3 - Economic Evaluation The two routing alternatives will be evaluated on the basis of their Net Present Value to determine the most economical option when estimated construction, property acquisition and operating costs are considered. Harza will develop pipeline sizing and pumping schemes for the two alternatives. Estimates of construction costs will be developed at the feasibility level (±25%) for the alternatives. Easement and land acquisition costs will be estimated based on information provided by BWC. Soils information as provided by the Client and the SCS will be used. Opera- �� tion/maintenance costs will be determined using labor and power rates provided by the Client. Present worth will be determined based on a planning period, interest rates and a financing strategy agreed upon with the Client. Subtask C.4 - Pumping Operations � Estimating the cost of construction and operation of pipeline alternatives will require an analysis of projected pumping requirements to convey water from the well field to Lake Decatur. Harza will optimize the combination of pumping plant and pipeline design that will result in the lowest Net Present Value of project costs over the e�tpected life of the proj ect. A total of 220 manhours have been budgeted to complete all subtasks of Task C. s9ioia A893092N-APP.I I-S
