Inscription.  This simple industrial building was constructed circa 1940 during a time of shipyard modernization and expansion, as World War II raged in Europe but the U.S. had yet to be attacked. Building 49 is a simple utilitarian structure that is 152 feet long by 46 feet long, with corrugated metal-clad walls over steel frames on a concrete foundation. The long monitor in the gable roof provides natural lighting inside its open interior, and two of the original three six-ton cranes in the building remain on rails under the roof. It was connected by rail lines to shipbuilding Slips 1 and 3 as well as nearby Slip 4.

Inside, steel hull plates and numerous other ship components were galvanized, or coated with zinc, in order to reduce corrosion: a process that involved lye, sulfuric acid and muriatic acid. The dangerous nature of this process may have led to the building being sited at the very edge of the yard.
