RSK Powerhouse Modernization Electric Infastructure

This is a sources sought synopsis for the purchase and installation of a 15kV Switchgear and Bus, Generator Step-Up (GSU) and Oil Instulated Transformers.
Background:
Dam Purpose: Navigation, hydroelectric power, and recreation.
History of Construction: Construction began in April 1964. Closure occurred in October 1970. The lock and dam became operational for navigation in December 1970. Power units 1, 2, 3, and 4 were placed on line on October 5, July 27, September 1, and November 2, 1971, respectively.
Type of Structure: The dam is constructed of rolled earth-filled material. The total length of the structure, including the spillway, powerhouse intake, and navigation lock, is 7,230 feet. The maximum height is 75 feet above the streambed. There is a service road to the right embankment and an access road to the lock in the left embankment.
Spillway & Outlet Works: A gated, concrete, ogee weir type spillway extends partly across the existing river channel and a portion of the right bank between the power improvements and the navigation lock. The spillway weir has a net length of 900 feet and is surmounted by eighteen 50- by 44-foot-high tainter gates. The gates are separated by seventeen 10-foot piers which support a 5-foot-wide service roadway bridge. The spillway has a capacity of 1,542,000 cfs at the maximum pool elevation(19.5 feet above the top of the power pool).
Hydrologic Data: The flood of record occurred in May 1943 with an estimated peak discharge at the dam site of 810,000 cfs
The United States Army Corps of Engineers is performing Market Research for the purchase of the following:
Replace the four main unit 15kV switchgear line-ups, replace the 480V station service switchgear, replace the unwatering/sump pumps and motors, transformer deluge containment, rehab of transformer fire protection system, governor kidney loop system upgrade, draft tube valve and spiral valve replacement, and install/terminate new GSU transformers to be supplied and placed by another contractor, at Robert S. Kerr Lock and Dam powerhouse.
The non-segregated 15kV bus from the generator to the switchgear and from the GSU transformers to the switchgear, draft tube valves, and spiral case valves will also be replaced under this project. The GSU transformer installation will require new transformer deluge containment including transformer pedestal structure modification. New equipment will replace aged and obsolete equipment, meet current applicable codes and standards while providing additional capabilities, and take advantage of new technology as appropriate. Both the design and construction aspects of this project will interface with ongoing and expected work at the powerhouse; specifically, other projects that directly relate to MEI work including the GSU transformer supply and turbine generator rehabilitation.
