AECOM Tishman served as construction manager for the original World Trade Center and built towers One, Three, Four, and Seven of the new World Trade Center. AECOM Tishman also built the Vehicular Security Center and retail program, and, as part of a joint venture, the Transportation Hub. In 2013, One World Trade Center was designated the tallest building in the Western Hemisphere at 1,776 feet.
Rebuilding the World Trade Center — a site imbued with deep national meaning and packed with subterranean, surface-level and vertical infrastructure — presented an engineering, urban design and construction challenge of enormous complexity. The series of projects has reshaped Lower Manhattan, transforming what was a business district into a vibrant neighborhood and a community that is stronger than ever.
