Construction Project: McNary JBS Outfall Pipe Relocation. Work consists of relocating the juvenile fish bypass outfall at McNary Dam on the Columbia River near Umatilla, Oregon. The contract will relocate the juvenile fish bypass outfall from its current location about 250 feet downstream from the dam in front of the powerhouse to a new location about 1100 feet downstream from the dam and 1200 feet away from the bank out into the river. The new pipeline will be comprised of three different sections. At the upstream end of the modification, just after the fish are routed through a primary/secondary switchgate, the primary bypass pipe will be replaced with 900 feet of 36-inch covered, corrugated metal flume elevated anywhere from 39 feet above the ground at the upstream end to ground level at the downstream end. The 900-foot length of the flume includes about 250 feet within an elongated circular loop to limit rate of descent. The flume will be supported by steel support structures spaced from 50 to 58 feet apart. The steel supports will stand on concrete footings set into the ground. The flume transitions to a fabricated steel junction box where the secondary bypass pipe rejoins the primary bypass pipe after leaving the juvenile fish facility. After the junction box, the bypass pipe goes underground in a 42 inch high density polyethylene (HDPE) pipe for a distance of 950 feet. After the HDPE pipe daylights at the western end of the run, the pipe transitions to a 36 inch smooth steel pipe that turns north and continues out over the water for a distance of approximately 1320 feet. The overwater portion is supported on drilled shaft, cast-in-place reinforced concrete piers spaced about 55 feet apart. The piers will generally be in water depths of 20 to 25 feet except for the final pier near the end of the outfall. That pier will support the pipe in a water depth of about 55 feet or more. The invert of the overwater portion of the pipeline will generally be about 11 feet above the water surface when the river is at the average tailwater elevation. Support piers will be required to extend a minimum of 10 feet into bedrock. In addition to the relocation of the outfall, the contractor will also be required to modify a number of pipes within the juvenile fish facility. These pipes are generally smaller in diameter, usually either steel or plastic pipe. Most of these pipelines are elevated as well and steel supports/concrete footings will be required. Contract requirements will also include demolition of existing pipelines to be abandoned within the juvenile fish facility as well as the existing outfall pipe and supports, including the underwater portion of the supports. Contract activities required include material acquisition and delivery, off-site fabrication of aluminum and steel hydraulic control structures and steel pipe supports, reinforced concrete placement, welding, crane work, pipe joint treatment, paint prep and painting, in-water construction, barge-mounted crane work, construction of reinforced concrete retaining walls, trenching and backfill, relocation of a comfort station drainfield, landscape restoration, installation of valves and water control mechanisms in the juvenile fish facility, electrical work, and on-site component assembly as well as miscellaneous associated tasks. Pipe slopes and alignments are critical to the performance of the completed system and will require tight tolerances during construction. Work conditions will include hazardous work such as elevated work, work on or over water, work under water, confined spaces, and cold or icy weather. The in-water work window is expected to be 01 Nov 2011 through 31 March 2012. The Juvenile Fish Facility will be shut down on 15 Dec 2011 and then is scheduled to be in operation on 15 March 2012. Commissioning of the work is expected to be completed by 12 March 2012. This project will be incrementally funded.
