DESCRIPTION OF WORK:
Dworshak Dam is located in central Idaho on the North Fork of the Clearwater River at 1.9 miles above the confluence with the Clearwater River. The dam is a straight axis concrete gravity dam with a maximum height of 717 ft. It is the third tallest dam in the United States. It was constructed between 1966 and 1972. Dworshak project has authorized purposes of hydropower and flood risk reduction. Normal outflows are made through three regulating outlet conduits that discharge into the spillway chute or through the three powerhouse turbines. Additional releases are made through the spillway, which is controlled by two Tainter gates.
The successful offeror will be required to manufacture, supply materials and install upgrades to the Regulating Outlet Valves at Dworshak Dam. Three regulating outlet intakes (RO) were placed in the dam during original construction. The upstream intake openings are 22 ft. tall by 16 ft. wide at the face of the dam. These bell mouth intakes taper, once inside the dam, to approximately 12.5 ft. tall by 9 ft. wide at the tainter gate valve (approximately 30 ft. inside the dam).
The work to be performed will include upgrade of all three ROs. Presently each RO valve has two hydraulic cylinders for operation. The main operating cylinder has a stroke of 15 feet which raises or lowers the valve. A hydraulic eccentric cylinder is used to unseat or seat the valve whenever the valve is moved. These hydraulic cylinders are provided high pressure oil from a hydraulic power unit located in the equipment room which is isolated from the RO valve room by a water tight door. Access is limited to the valve room via the watertight door and an airshaft from the valve room to the top of the dam. Position of the RO valve is provided by linkage to a position sensor.
The work will also include replacement of the eccentric cylinder and the valve lifting cylinder with cylinders that incorporate rod locks to prevent un-intentional motion. Replace the existing RO position indication system with a magneto-restrictive indication system built into the valve lifting cylinder. Replace the valve 18 inch wall support bearings and 23 inch eccentric bearings along with appurtenant seals and fasteners. Replace the valves controls both locally at the valve shaft and within the control room. Replace the hydraulic power units for the valves along with grease lubrication system. Also, the contractor will be required to perform patching of concrete and crack sealing on the concrete spillway below the valves. For RO Valve #3, new 36” diameter access shaft will need to be cut to realign the existing RO3 Vent/Access Shaft that is offset approximately 2 feet to the axis of the dam.
