  • Elevators and escalators inspected for safety and quality.

Soaring above the city at 1,176 feet, One World Trade Center is America’s tallest building and a New York landmark. The building’s success relies heavily on the proper installation and maintenance of the elevators and escalators that transport tenants to stops within its 104 floors. The elevators move at a speed of 2,000 feet per minute, making them some of the fastest in the Western Hemisphere.

What We Did

Vertical Transportation Excellence (VTX®), the vertical transportation division of Gannett Fleming, provided detailed inspections, test witnessing, field surveys, and quality control/quality assurance services for the installation of 71 elevators and 11 escalators. As the number of completed floors increased throughout construction and hoists were removed, Gannett Fleming kept pace with the interior elevator installation, working 16-hour days to complete each inspection. Code-required testing ensures that the elevators run smoothly and safely, providing a smooth ride for tenants and tourists.

Key Features

  • Technical guidance led to the successful installation of 82 pieces of vertical transportation equipment.
