Sculptor Kenneth Snelson is tired of having his name all over the derided spire atop One World Trade Center. It has been widely reported that Snelson consulted with Skidmore, Owings & Merrill (SOM) on the 441-foot-tall spire that brings the tower to its highly symbolic height of 1,776 feet. But he said he was only peripherally involved in the early stages of the design and is not all that connected to what now towers above Lower Manhattan. Snelson said everyone involved in the design of the spire had the best intentions, but as for its final iteration, he’s no fan. “I don’t know why somebody doesn’t decide, ‘well, we should remove the spire,’” he said.

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

Anticipation was running as high as the tower itself as construction crews were standing by to raise the final two sections of the spire to the top of One World Trade Center today, a move that would have officially made the tower the tallest building in the Western Hemisphere at 1,776 feet, but high winds brought on delays. The final two sections of the 408-foot-tall spire, capped by a shining, pointed beacon, were scheduled to rise this afternoon, but the Port Authority decided to wait for for clearer skies to top-off the tower.

The spire that will one day reach a point 1,776 feet above Lower Manhattan on the ever-progressing World Trade Center is en route to New York via a barge from Valleyfield, Quebec, Canada. The Port Authority of New York & New Jersey put out a statement that the giant antenna embarked on its 1,500-nautical-mile journey on November 16 and is expected to arrive at Port Newark any day now, but a tracking website doesn’t appear to be working. Smaller pieces will be trucked in over the next month. Each segment of the spire weighs from five to 67 tons. Once the spire is on site, construction is expected to take about three months to complete.
