It was in 2013 that World Trade Center Tower 1 (or 1WTC), New York’s new world-class architectural landmark, became the tallest building in America with a height of 541 meters or 1,776 feet, symbolizing the year of the declaration of independence of the United States.
ADF Group was selected as the best partner for the construction of this important project because of our staff’s know-how and our proven expertise in complex steel structures. ADF’s contract was for the engineering of connections, the manufacturing and delivery of the complex steel framing as well as the heavy, oversized steel assembled components of a significant portion of this skyscraper. This major project took place over a period of five years.
