HistoryThis one-story, plus mezzanine, 230,000 sq. ft. building was constructed in 1984 and housed the general fabrication, metal and machine shop for non-plutonium pit components, primarily stainless steel. It is "L" shaped, and is constructed of a steel frame with corrugated metal walls on a poured concrete foundation. The shallow pitch roof is metal and the metal doors have shed roof porches. There are round metal exhaust fans along the exterior walls of the building. The fixed, single-pane windows are only on the mezzanine level, except on the east end of the south wall, where there are windows on the ground level as well. In 1984, this building also assumed stainless steel operations from Building #881. The first tool-made samples were producing in May 1985. At the time, the structure was described as the most modern non-nuclear manufacturing building in the weapons complex.
