The Portland District Corps of Engineers plans to issue task order number 0014 under contract W9127N-08-D-0003 to MWH Americas, funded through the Recovery Act, to support the Denison Hydro Turbine Rehabilitation project. The contractor's responsibilities include conducting an economic and benefit-cost ratio analysis, preparing a comprehensive mechanical design package for turbine rehabilitation, and developing a complete set of Plans and Specifications for the project. This project involves rehabilitating two S. Morgan Smith Francis turbines located on the Red River near Denison, Texas, which are operated by the U.S. Army Corps of Engineers, Southwestern Division, Tulsa District. The turbines in question feature 191.5-inch diameter runners with 15 blades each and 20 wicket gates, with the wicket gate pad height measuring approximately 69.375 inches. The turbines rotate clockwise at 90 rpm, operating under a rated head of 102.5 feet and producing a rated output of 56,000 horsepower. The associated generators are rated at 53.5 megawatts. The work falls under NAICS code 541330 and is managed through the Portland office of the Department of Defense, emphasizing engineering and design services to support the rehabilitation and modernization of this hydroelectric facility.
