It measures 552 by 164 feet and stands 85 feet high.","why_significant":"The nomination presents it as one of the most impressive early 20th century industrial buildings in the San Francisco Bay Area and, when built, the largest of its kind on the Pacific Coast. It is the most prominent industrial work of architect John Reid, Jr. It is also the nucleus of a shipyard that played nationally recognized roles in both World Wars and shaped the industrial development of the Alameda estuary.","narrative":"Built in 1918 on the Alameda waterfront, this enormous steel-frame shop measures 552 by 164 feet and rises 85 feet. Red brick piers and spandrels frame vast industrial windows that fill about 90 percent of the wall area, and a monitor skylight lights an open central space once served by a giant overhead crane. It was designed by San Francisco architect John Reid, Jr., with engineers Hall and Snyder, to make marine turbines and engines for the Union Iron Works shipyard, later part of Bethlehem Steel. At completion it was the largest building of its type on the Pacific Coast, and it was called the finest machine shop there. The yard it served built 58 ships between 1916 and 1923, set wartime speed records, and repaired more than 1,000 vessels in World War II. The shop later fabricated structural steel. Most neighboring yard buildings have been demolished, leaving this one as a rare survivor. It has stood vacant since 1972.","period_of_significance":"1900- (specific date 1918)","architect_builder":"John Reid, Jr., architect; Hall and Snyder, engineers","architectural_style":null,"criteria":[],"status_note":"Vacant since 1972; the building is little altered apart from replaced ground-level doors and vandalized window panes.
