| 1 WTC reached the 100th floor in April 2012
|
The Port Authority is nearing completion progress on the $3.8 billion
1 World Trade
(formerly called the "Freedom Tower"). Located at the northwest corner of the WTC site, installation of steel columns and core concrete continues.
The skyscraper was built according to a revised design released in June 2005. The new design retains essential elements of the original plan -- soaring 1,776 feet into the sky -- but features a smaller, cubic base set back further from West Street to protect the building against future attacks.
Rising from its square base -- which will be constructed of impermeable concrete and steel -- the redesigned 1 WTC will taper into eight tall isosceles triangles, forming a perfect octagon at its center. The observation deck will be located 1,362 feet above ground (105 stories) and there will be a parapet at 1,368 feet, the heights of the original Twin Towers. From there, an illuminated spire containing will rise to a final height of 1,776 feet.
Other key elements include; 2.6 million square feet of office space, tenant amenity spaces, world-class restaurants, below-grade retail, and access to the PATH, subway, and World Financial Center. According to the Port Authority schedule, the tower is expected to be substantially complete in late 2013, with some interior fit out continuing into 2014.

Frequently Asked Questions
|
|
Q:
|
When will 1 WTC open?
|
|
A:
|
One World Trade Center is currently scheduled to open in late 2013. The finished structure will include 2.6 million square feet of office space, an observation deck, restaurants, and broadcast and antennae facilities. Underground, there will be retail shops and access to the PATH rapid-transit system, as well as a passageway to the World Financial Center.

|
Q:
|
Why did work on the 1 WTC take so long to start?
|
|
A:
|
One significant delay was the redesign of the tower in the spring 2005, to better accommodate security measures at street level. However, preliminary construction on the then-called "Freedom Tower" started on July 4, 2004, and crews have worked steadily since then.
Since fall 2008, tower construction is underway.

|
Q:
|
What are some of Tower 1 safety features?
|
|
A:
|
To address security concerns, the redesigned building's setback distance from West Street has been increased from 25 feet to an average of 90 feet, and its cubic base will be constructed of impermeable concrete and steel. Additionally, the building will feature advanced life safety systems that exceed the city building code, structural redundancy, extra-strong fireproofing, and biological and chemical filters in the air supply system. There will also be extra-wide pressurized staircases, low-level emergency lighting, and interconnected redundant exits. Finally, emergency communication cables will facilitate enhanced emergency response, and there will be a dedicated staircase for use by firefighters and "areas of refuge" on every floor.

Q:
|
How is 1 WTC using environmentally conscious systems?
|
|
A:
|
Tower 1 will use the latest technologies to maximize efficiency and minimize waste and pollution in both its construction and eventual operation. It is being built according to World Trade Center
Sustainable Design Guidelines
and will, at a minimum, conform to the
U.S. Green Building Council’s
Leadership in Energy and Environmental Design (LEED) standard. According to architectural firm Skidmore, Owings and Merrill, “Specific achievements of 1 WTC will include use of renewable energy for at least 20 percent of the building’s energy needs; state-of-the-art energy conservation technology to reduce energy demand; better interior “daylighting” and views of the outside for occupants due to ultra-clear glass technology; improved indoor air quality due to outside-air ventilation and use of building materials without toxic materials such as volatile organic compounds (VOCs); water conservation due to reuse of rainwater for building cooling and irrigation; reduction of vehicular traffic via proximity to public transportation and provision of facilities for bicycle commuters; waste reduction through recycling of construction debris and use of recycled-content building materials; natural resource protection via use of sustainably harvested wood; and cleaner air in the community due to use of
ultra-low-sulfur diesel
fuels and particulate filters on construction vehicles, for which the EPA has already given Silverstein Properties (the tower’s developer) a 2004 Environmental Quality Award.”
