The Spiral – 66 Hudson Boulevard, a 67-story office building, was built in the Hudson Yards neighborhood of Manhattan. Standing at 1,031 ft tall and featuring 2.85 million sq ft of office space, the building’s design includes terrace gardens along the exterior in the shape of a spiral, leading to the name of the structure. Roughly 30,000 tons of structural steel were fabricated for the project, and ironworkers and operating engineers completed more than 500,000 hours of steel erection.
