Work is approaching topping out on 66 Hudson Boulevard, aka The Spiral, a 1,041-foot-tall commercial supertall in Hudson Yards and number seven on YIMBY’s December construction countdown. Designed by Bjarke Ingels Group and developed by Tishman Speyer, the skyscraper occupies a full block between Tenth and Eleventh Avenues and 34th and 35th Streets and will yield 2.85 million square feet of office space. Turner Construction Company is serving as the construction manager, Banker Steel is in charge of manufacturing the steel, and Permasteelisa is the contractor for the glass enclosure for the 66-story project, which is expected to cost $3.7 billion.

Construction of the concrete core appears to have topped out at 50 Hudson Yards, a 1,011-foot-tall commercial supertall in Hudson Yards and number eight on our countdown of the tallest buildings in progress in the New York metropolitan area. Designed by Norman Foster of Foster + Partners and developed by Related Companies with Oxford Properties, the 58-story skyscraper will yield 2.9 million square feet of office space, making it the largest building by volume in the first phase of the Hudson Yards master plan.
