Z--Lower Granite Dam Units 3-6 Cavitation Repair

Construction Project: Units No. 3-6 Cavitation Repair at Lower Granite Dam in Whitman and Garfield Counties, Washington. This will be a firm-fixed-price contract. Estimated construction magnitude is between $5,000,000 and $10,000,000. The period of performance is approximately May 2011 through April 2013, with 2 units to be repaired during May 2011-April 2012, and 2 more units during July 2012-April 2013. 100% Performance and payment bonds will be required. The work consists of providing all labor, technical expertise, materials, equipment, scaffolding and appurtenances necessary to accomplish the following turbine cavitation repairs for Units 3, 4, 5, and 6 at Lower Granite Powerhouse: Cavitation damage repair shall be performed on the turbine discharge ring only. A portion of the existing discharge ring material shall be ground or milled to good metal and anchoring the discharge ring/draft tube liner to the concrete. The contractor shall install 1 inch diameter reinforcement bars into the predrilled holes with epoxy-resin cartridges. After curing, the bars will be welded to the interior surface of the discharge ring and the ends cut off and ground flush. The discharge ring shall be spot repaired, built up with mild steel weld metal, stainless steel weld overlay placed, and the discharge ring surface ground and machined to the finished profile. There is some removal of concrete and restoration of the concrete surfaces and architectural finishes to the required lines and grades. The Contractor shall refurbish the discharge rings by removing material from the existing ring by machining, sanding, or grinding methods; repair and overlay welding; and surface finishing of the welded areas by machining and/or grinding, unless otherwise approved. No more than a 1/2 inch thickness of weld material shall be uniformly laid on the discharge ring, unless otherwise approved. Localized cavitation and surface damaged areas shall also be repaired. The contractor shall provide a procedure that describes the method of monitoring the weld interpass temperature and a detailed description of the method of protection of the turbine and generator from damage due to the repair process if that process involves unit rotation (e.g., thrust and guide bearing during machine rotation for discharge machining; weld current through the thrust or guide bearing). Welder qualification shall be in accordance with one of the following codes: (1) Section 4, Part C, of AWS D1.1, or (2) Section IX of the ASME Boiler and Pressure Vessel Code (ASME BPVC), or (3)AWS B2.1 (for cladding), whichever is most applicable to the work being performed. Cavitation repair welding will distort the discharge ring/draft tube liner causing it to pull away from the concrete behind it. The resulting voids must be filled with epoxy to absorb vibration of the discharge ring during turbine operation. The contractor will perform drilling and washing the epoxy injection holes and air relief holes; making epoxy-injection connections; furnishing, transporting, mixing and injection of the epoxy; patching the finished epoxy injection holes; clean-up of the draft tube lining and such other operations as are incidental to the drilling and epoxy-injection. Following the repair welding, the Contractor will inject a two component low viscosity epoxy resin adhesive behind the discharge ring/draft tube liner to fill voids created by distortion. Runner Blades, Runner Cone, Runner Hub Repair, Seal Retainer Segments and other Water Passage Elements are optional work items that would require excavation and deposit of mild steel or 309L stainless steel to a depth that is within 1/4 to 5/16 inch of the finished surface. This area would be finished with a stainless steel overlay. Solicitation No. W912EF-11-R-0008 will be posted to the FBO website on or about February 28, 2011.
