Not only is 580 Fifth the heart of the United States diamond and jewelry trade, it is also the headquarters of Royal Masonry and Concrete, where we occupy the top two floors. Completed in 1927 by architects Warren and Wetmore, the building comprises a Neo-Gothic 33-story tower on the east side and a 13-story building on the west side. In 2023, building owner Forty Seventh Fifth Co. hired RCM to repair the facade, which included extensive terracotta panel replacement, roof repairs, corner and parapet replacement, as well as decorative stone repairs. We also performed extensive work to waterproof the entirety of the building envelope.
