R -- SAFETY OF DAMS PROJECT-EAST FORK Sol C-90-011. Due 062395. POC Jim Morsette, Safety of Dams Officer 406-395-4207. Perform safety and enlargement studies on East Fork Dam. 1. Safety of Dams (SOD) and Operation and Maintenance Deficiencies. A. Identify modification alternatives to mitigate safety of dams deficiencies as identified in the DA prepared by the Bureau of Reclamation, dated May 17, 1990. As interim and possible permanent corrective action, develop nonstructural alternatives (Early Warning System) to address SOD deficiency. B. Inability of the dam and appurtenances to pass floods greater than 6.4 per cent of the general storm probable maximum flood (PMF) and the downstream static slope stability factor of safety is unnaceptably low for normal operation. C. At the option of the Contracting Agency prepare structural conceptual designs to address SOD deficiency. D. Prepare conceptual designs and cost estimated for modification alternatves selected by the Contracting Agency for alternatves developed in ``B'' and ``C'' above. E. Identify remediation measures to designs as appropriate cost O&M efficiencies identified in the DVA and prepare cost estimates for the required activities. 2. Reservoir Enlargement. A. Develop alternative schemes for increasing reservoir storage to 700 acre feet total capacity. Two basic schemes will be required: 1. enlarging the existing embankment dam. A variation of spillway type, location, and capacity will be identified with enlargement alternatives addressing all SOD concerns. Potential alternative schemes will be defined to an extent adequate for selection for alternatives for conceptual development. B. Prepare conceptual designs and cost estimates for alternatves selected by the Contracting Agency. C. Prepare downstream inundation studies for selected modification alternatives to identify an inflow design flood that results in no incremental consequences from dam failure for the enlarged reservoir. D. Perform Environmental Assessment for East Fork. The evaluation criteria for the RFP will be based on the following percentages: A. 30% professional qualification and experience of personnel for assignment to work in a specific discipline. B. 30% exhibited competence of the firm in this specialized displine. C. 16% exhibited ability and resources of the firm to plan. Manage and coordinate work as a team on a project that consists of several phases of work, and availability of additional qualified regular employees for support. D. 12% specific performance record on previous and similar technical work for tribes, Government or private industry. E. 12% Indian preference compliance. Contract Range $75,000 to $150,000. (132)
