Construction crews on the massive One World Trade Center site Wednesday reached a milestone by placing the largest steel column to date for the $3.1 billion tower in Lower Manhattan.
The 60-ft, 70 ton beam will serve as one of 24 perimeter columns that surround the building’s core. Once placed, the columns will allow the initial floors of the tower – including the lobby – to be built out. Each of the 24 columns was manufactured at the ArcelorMittal plant in Luxembourg. The steel plates were shipped to North America and fabricated in shops in South Plainfield, N.J. and Terrebonne, Canada. The columns are being delivered to the site from New Jersey over the George Washington Bridge.
