Last Wednesday, developers Related Companies, Mitsui Fudosan America, and Oxford Properties celebrated the grand opening of 50 Hudson Yards, a 78-story supertall commercial skyscraper in Hudson Yards. Designed by Foster + Partners, the 1,011-foot-tall structure is the largest building by volume in the first phase of the Hudson Yards complex and the fourth-largest in the city overall, yielding 2.9 million feet of office space. ArcelorMittal provided the steel components, R&R Scaffolding provided the BMU equipment, Langan Engineering is the civil and environmental engineer, and WSP is the structural and MEP engineer for the $3.8 billion project, which occupies a full block bound by West 34th Street to the north, West 33rd Street to the south, Tenth Avenue to the east, and Hudson Boulevard to the west.
