Construction Progress

Mitsubishi Power Systems Americas – Savannah Machinery Works
February 2012

The joint venture team of Batson-Cook and H. J. High has completed construction of Bay 4 which is the latest addition to the project. With bays 1-4 and the office building at the front of the project complete we have constructed approximately 325,000 sf. This includes bays for refurbishing parts of the compressors and bays for assembling entire gas turbines. Bay 4 is unique in that we installed (2) 250T bridge cranes that contain (2) auxiliary 50T cranes. These will allow the user to make tandem picks in excess of 400T. All the foundations, building steel and crane runways were sized for this loading. The bay also has (2) 30T cranes for general use.

A large portion of the floor has 2” steel plates installed with concrete in filled around them. This area will be covered with scaffold that will allow the user to vertically align the turbines to very minute tolerances. The 200 plates have to be set dead level.

The balance bunker is proceeding as well. The steel chamber is now outlined with vertical steel and will soon have the roof steel in place. Once this is complete we will weld steel plating inside the chamber on the walls and ceiling. All welds are inspected for leakage as this room will be drawn down in a vacuum. The last act will be welding the same steel plates outside the chamber and then filling the inside void with concrete. When finished it will provide a 7’ thick steel and concrete wall. Needless to say, what is in the room is going to stay in the room.
