What it’s like High atop One World Trade Center
It’s a 1,776 ft. symbol of America’s freedom, determination and resilience. One World Trade Center took nearly a decade of planning and construction to complete, but it’s finally here. The final piece of the puzzle was erecting the massive 408-ft. spire atop the roof the building.

The final section of the 758-ton spire was set into place in May (2013). One World Trade Center then officially became the Western Hemisphere’s tallest building, surpassing the Willis Tower in Chicago by more than 300 feet.

Needless to say, it was a challenge for architects and workers to put the finishing touches on the $3.9 billion project. Safety was of the utmost importance when erecting the top deck and spire sections.

Safety of rooftop workers is ensured by a series of horizontal and vertical tracks designed to prevent falls. The rigid-track fall protection was designed by Rigid Lifelines and in all, 1,975 linear feet of steel tracks were installed atop the building to ensure worker’s safety when doing routine roof maintenance on the roof itself, communications equipment and lighting.
Roof workers can navigate the base of the spire via a 64-foot radius platform with the trolley and track system providing safety against slips and falls. Weather can be unpredictable at nearly one-third of a mile off the ground, not to mention other risks associated with working at such heights, such as vertigo.
Green Building Technology is at the Forefront of the One World Trade Center Design
Nearly 75% of One World Trade Center is made from recycled or eco-friendly building materials.
The concrete used in construction was mixed in a more eco-friendly fashion that helped save over 30,000 gallons of water and 8 million kWh of electricity.
The building is powered by one of the largest fuel cells in the world, able to run at a 95-percent efficiency rate.
Exhaust fumes are recycled and used to heat/cool the building.
Rainwater collection systems provide water at the entire World Trade Center complex, including the waterfall memorial sites.
Sensors strategically positioned in rooms throughout the building automatically dim the lighting based on the lighting conditions outside.
One World Trade Center’s green design has earned it a LEED Gold Certification.
Constructing a National Treasure
Breaking ground in 2004, the One World Trade Center project took nearly a decade to complete. It’s safe to say it’s one of the most incredible office buildings in the world.
The building’s roof stands 1,368 ft. tall, which is identical to the height the North Tower stood. Add in the 408-ft. spire, and you achieve a symbolic 1,776 ft. total. For those of you who failed U.S. history class, the Declaration of Independence was signed in 1776.
The fact that One World Trade Center features a sustainable design and green technology everywhere you turn is important to the future of skyscraper design. It’s sort of a blueprint for future architects. There’s no doubt that sustainable design is the future.
If you weren’t able to spend the last decade in NYC watching One World Trade Center become a reality, I’ll do you a favor and show a quick 2-minute time-lapse video that sums it up for you.
