- R09PS30017 A6 Turbine Seal Rings for Hoover Dam-NevadaNAICS: 331513 Steel Foundries (except Investment)PSC: J0428 Maint-rep of engines & turbines The Bureau of Reclamation (Reclamation), Lower Colorado Region, has a requirement for new seal rings, ranging in size from 140" to 188" in diameter. The new seal rings will be installed on 130 megawatt (178,000 horsepower) hydroelectric Francis type turbines and will have running clearances no greater than 0.045" radial between the rotating and stationary seal rings. Past seal ring replacements utilized nickel-aluminum bronze paired against austenitic stainless steels such as CF8/304L. Wear rates observed using these materials were excessive, primarily on the aluminum bronze rings. Nitronic 60 stainless, with excellent mechanical properties, is now being used in place of the aluminum bronze to extend the life of the turbine seal rings and improving the long-term efficiency of the turbines at Hoover Dam. The principal components of the work include the following: (1) The stationary seal rings shall be fabricated as one piece, seamless and continuous either by centrifugal casting or ring roll forging; (2) The seal rings shall be furnished oversized relative to installation - final machining of the seal ring clearance surfaces will be done in the field by Hoover Dam staff to assure proper clearances between the stationary rings and runner as well as accurate pre-stressing of the rings during installation; (3) The seal rings shall be delivered in the fully annealed condition to insure minimal internal stresses and distortion during final machining operations by government personnel. The manufacturers suggested heat treatment procedure information, including intermediate "tempering", furnace type, and controls shall be reviewed by the Government prior to any heat treatment of the material. This solicitation is unrestricted. The North American Industry Classification System (NAICS) code for this acquisition is 331513 Steel Foundries (except Investment) with a small business size standard of 500 employees. The solicitation, in the form of a Request for Quote (RFQ), will be issued on or about August 5, 2009 with offers due on or about August 19, 2009. The RFQ will include evaluation factors for experience, past performance, and price. The Government anticipates awarding multiple indefinite delivery-indefinite quantity type contracts with a one-year base period and two two-year option periods. Fixed-price delivery orders will be issued as required to purchase the components. The estimated magnitude of each task order is $5,000 to $100,000 with a total contract value of each contract awarded estimated between $100,000 - $5,000,000. The estimated contract award date is September 14, 2009. No documents will be available until the solicitation is issued. The solicitation will only be issued electronically via www.FedBizOpps.gov. The Government reserves the right to issue the solicitation on paper or CD if the FedBizOpps (FBO) web site becomes inoperable or if the Contracting Officer determines it is in the Government's best interest to do so. Offerors should register at the FBO to be included on the offeror list in order to receive notifications pertaining to the solicitation, or visit the FBO website after issuance download the solicitation and any subsequent amendments.
