RECOVERY--R--Emergency Water Supply Line Replacement. Engineering and Design - Alternative X-Option C Tunnel & 72 pipeline and Alternative 3A Pump Station and 36 Pipeline. Don Clausen Fish Hatchery Warm Springs Dam Sonoma County, CA.

This project is for work required to complete the Engineering and Design (E&D) for two separate Alternatives. The A-E shall prepare two separate packages of Plans and Specifications as well as a Design Documentation Report for each alternative. Both Alternatives are intended as Emergency Water Supply Line Alternatives for the Don Clausen Fish Hatchery, at Warm Springs Dam, Sonoma County, California. Successful completion of this SOS involves: A. The preparation of plans and specifications packages that reflects 65% of completion. B. Design Documentation Reports (DDR) that shall reflect as a minimum the completion of a DDR that was prepared for a feasibility study during the planning stage. The DDR shall document the detailed design/analysis for all project features including pre-design geotechnical investigation and surveying. Alternative X-Option C proposes a tunnel construction through the left abutment and 72-inch outlet pipe construction that connects to the wet well and to the Sonoma County Water Board pipeline. The design of this alternative shall account for and be integrated with the design and construction plans for the outlet water pipe construction to be tied to this project as designed by the Sonoma County Water Board. Alternative 3A proposes a Pump station construction and the tie-in to the wet well in the Control Structure as well as a 36-inch pipeline construction over the left abutment and connection to the stilling basin for the hatchery. Required completion includes preparation of the design plans, design specifications, construction cost estimate, construction schedule for the project to 65% completion.
