Construction is moving along at 66 Hudson Boulevard, aka The Spiral, the eighth-tallest skyscraper under construction in New York City in YIMBY’s annual countdown. Designed by Bjarke Ingels Group, the massive commercial office tower is rapidly ascending toward its 1,031-foot-tall parapet over the Midtown neighborhood of Hudson Yards. Tishman Speyer is the developer, Turner Construction Company is the construction manager, and Banker Steel is in charge of fabricating the 66-story, $3.7 billion supertall.

The steel superstructure is continuing to rise skyward at 50 Hudson Yards, the number-nine project on YIMBY’s countdown of the tallest buildings under construction in New York City. Workers have made a significant amount of progress since we checked in one year ago, when foundations were just beginning to make their way toward street level. Now, a mass of steel beams, columns, and trusses for the wide floor plates are ascending around the reinforced concrete core. Designed by Norman Foster of Foster + Partners, the 1,011-foot-tall commercial office supertall is the final segment of the first phase of Related Companies‘ Hudson Yards complex. Oxford Properties and Mitsui Fudosan are developing the 2.9-million-square-foot structure, the largest component in the 28-acre master plan by volume.
