Seven tons of glass and steel clad a structural stainless frame on the Western Hemisphere’s tallest building.

Brooklyn-based metal fabrication company Kammetal and DCM Erectors of New Jersey were selected to fabricate and install the crowning beacon atop the spire on 1 World Trade Center. The fabrication team executed SOM’s design for a dynamic and complex adornment to one of the country’s most anticipated buildings, along with the help of engineers at Buro Happold to ensure safety at 1,776 feet.

To craft a 15-ton, 50-foot beacon that accounted for thermal expansion and movement, Kammetal modeled and drew their designs in SolidWorks. The company’s team laser cut 48 triangular 316 stainless steel panels with ¼-inch thickness in a nondirectional finish to clad DCM’s square tubular steel frame. “Before we started the project, we had the structural frame 3D scanned to generate a point cloud,” explained Sam Kusack, president at Kammetal. “Because the structure was so dynamic—it contains zero right angles or reference points—we had to verify the conditions.” Read More
