Standing 1,776 feet tall, One World Trade Center is the tallest building in the United States and a defining symbol of resilience, renewal, and American craftsmanship.

Constructed on the site of the original World Trade Center complex, the tower serves as the centerpiece of the rebuilt World Trade Center campus in Lower Manhattan.

Construction began in 2006, and the building officially opened in November 2014. Designed by Skidmore, Owings & Merrill, the 104-story skyscraper features more than 3 million square feet of office space and is home to the One World Observatory, offering panoramic views of New York City from floors 100 through 102. The building’s iconic height of 1,776 feet was intentionally chosen to commemorate the year of American independence.

The successful completion of this landmark project required the expertise of thousands of skilled union tradespeople, including members of the International Union of Elevator Constructors. IUEC members played a vital role in the installation and operation of the building’s advanced vertical transportation systems, helping ensure safe, efficient movement throughout one of the world’s most recognized skyscrapers.

Today, One World Trade Center stands as both an engineering achievement and a lasting testament to the skill, dedication, and professionalism of union construction workers.
