For the purposes of this Sources Sought, please reference RFP W912DW-08-R-9999 The U.S. Army Corps of Engineers (hereinafter referred to as the Corps ), Seattle District is seeking sources to complete the final excavation to design grade and install the personnel access and fish attraction water tunnel for the Fish Passage Facility at Howard Hanson Dam, Howard Hanson Dam is used for flood control and the public drinking water supply for the Ci ty of Tacoma and is located in King County near Ravensdale, Washington. The Dam is located wholly within the City of Tacoma Watershed and access is controlled by a gate at the Citys Headworks Facility. Personnel and equipment accessing the Dam construct ion areas will be required to register with the City. Howard Hanson Dam is located 4.5 miles upstream from the Headworks facility. The existing Dam structure is being modified to include a multi-elevation fish passage facility to ensure upstream and downstream movement of endangered salmon species. This modification is required under the Endangered Species Act and the 1998 Biological Opinion for the City of Tacomas Additional Water Supply Project. The fish passage facility structure constructio n currently is scheduled for 2010. The final excavation and tunneling must be completed before the facility structure can be constructed. The current excavation is approximately 80 feet deep in fractured volcanic bedrock with the excavation bottom elevation at elevation 1074 feet and the work site is separated from the reservoir by a cofferdam to elevation 1169 feet. Ground surface elevations vary from 1150 to 1165 feet around the excavation. The contractor will be expected to deepen the excavatio n to elevations ranging from 1054 to 1021 feet and construct two tunnels that will link the final structure to the existing outlet tower and the existing outlet tunnel. The personnel access tunnel, located from elevation 1071 to 1067.4, will be approximat ely 30 feet long, 6 feet wide and 8 foot tall concrete lined tunnel excavated through rock. The attraction water conduit upstream invert is at approximately elevation 1129, will be approximately 65 long, 6 feet wide of variable height with a minimum of 9. 5 feet, is concrete lined, excavated through rock, and will connect the final fish passage facility to the existing outlet tunnel. The attraction water conduit construction includes demolition and construction of the portal at the juncture with the existi ng outlet tunnel. Excavation of portions of the sidewall of the excavation above elevation 1074 feet are also required. The contractor will be expected to control all water from the concrete work to be compliant with the Corps Water Quality Permit with t he Washington State Department of Ecology. All construction spoils will be hauled to designated disposal sites within the Watershed. A bedrock dewatering system is already in place and will managed by the government. The Corps previously released this work scope in September 2007. All technical requirements remain the same; however, THIS work scope DOES NOT include several minor pieces of work that will be completed in 2008. All work contained in this work scope will be accomplished in the dry be hind the existing coffer dam. REQUIREMENT: Offerors must have a positive, proven track record in the industry and reputation for completing work within the negotiated schedule, scope, and cost for complex blasting, excavation, and tunneling pr ojects near critical structures. The specific requirements are as follows: " Tunnel excavation and liner construction, including excavating tunnels in r ock, installing rock support in unlined tunnels, and installing concrete liners while protecting nearby critical structures. " Work to be completed in the existing flood control tunnel is constrained by the annual outage window in the flood control tun nel, which occurs from approximately mid-July to Mid-September " Rock excavation, including rock slope stability support (e.g., cement-grouted rock dowels and shotcrete). " Close-in blasting or mechanical rock excavation near critical structures " Foundation drilling and grouting in bedrock (for facility construction at final design elevation). " Instrumentation installation, maintenance, and data interpretation for early warning of potential excavation slope failure and to vary excavation metho ds near critical structures. Instrumentation previously installed includes, vibrating wire piezometers, inclinometer casings, multi-point borehole extensometers, liquid level gages, crack meters, strain gages, sister bars, load cells, and seismographs.<BR >" Water quality maintenance " Management of water that enters the excavation.
