Z--Lower Granite Permanent Closures: Fish Screen Slots and Wagner Horns

Work is to permanently close Fish Screen Slots and Wagner Horn openings at Lower Granite Dam on the Snake River. Openings are currently screened. Work area cannot be unwatered. Diving is required. There are 6 turbine units at Lower Granite Dam. Each turbine unit has 3 Fish Screen Slots and 9 Wagner Horn openings. All existing screens shall be removed from the Fish Screen Slots and Wagner Horn openings by the Contractor. Wagner Horns are 3 foot diameter, Corrugate Metal Pipe lined, openings. They are accessed from the turbine intake. Contractor shall construct reinforced concrete plugs, and grout plugs into place in the turbine intake. Reinforced concrete plugs are roughly 6-foot tall, 30-inch diameter, with bottom form, and grout injection ports. Estimated dry weight per closure plug is 5,300 pounds. Contractor shall pressure wash the corrugated inside walls of the conduit prior to precast plug placement. Grout shall be pumped through the injection ports to fill the space between the precast plug and the existing interior conduit walls. After the grout has hardened, injection ports shall be removed from the forms, and area ground smooth. Fish Screen Slots are approximately 24 feet long by 4 feet wide. Estimated dry weight of existing Fish Screen Slot Screens is 8,000 pounds per screen. Contractor shall modify existing screens and screen legs, form and pour a reinforced concrete plug on the screen (approximately 7 feet high), then return screen and plug to the Fish Screen Slot. Packing shall be placed around plugs (approximately 6 inches down from the top of the plug) and covered with cementitious grout. Plugs shall be covered with approximately 6 feet of reinforced tremie concrete. Contractor shall pressure wash side walls of the Fish Screen Slots prior to placing tremie concrete. Estimated dry weight of each Fish Screen Slot plug (prior to tremie placement) is 90,000 pounds. Work must be accomplished between August 3, 2014 and January 30, 2015. The construction magnitude is estimated between $1,000,000 and $5,000,000. 100% performance and payment bonds will be required.
