About One World Trade Center:
One World Trade Center, abbreviated as 1 WTC and commonly known by its previous name Freedom Tower, is the lead building of the new World Trade Center complex in Lower Manhattan, New York City. The 104-story supertall skyscraper is being constructed in the northwest corner of the 16-acre World Trade Center site, occupying the location where the original 8-story 6 World Trade Center once stood. The building is bounded to the west by West Street, to the north by Vesey Street, to the south by Fulton Street, and to the east by Washington Street. Construction on below-ground utility relocations, footings, and foundations for the building began on April 27, 2006. On March 30, 2009, the Port Authority confirmed that the building would be known by its legal name of One World Trade Center, rather than the colloquial name, Freedom Tower.
At the time of its completion in 2013, One World Trade Center will be the tallest building in the Western Hemisphere and the third-tallest building in the world by pinnacle height, with its spire reaching a symbolic 1,776 feet (541.3 m) in reference to the year of American independence. 1 WTC has been the tallest building in New York City since April 30, 2012. The new World Trade Center complex will also feature three other high-rise office buildings, located along Greenwich Street, and the National September 11 Memorial & Museum, located just south of One World Trade Center, where the Twin Towers once stood. The construction is part of an effort to memorialize and rebuild following the destruction of the originalWorld Trade Center complex during the attacks of September 11, 2001.
Along with the protection offered by the reinforced concrete base, a number of other safety features were included in the building's design, in order to better prepare it for a major accident or terrorist attack. These features include 3-foot (91 cm) thick reinforced concrete walls for all stairwells, elevator shafts, risers, and sprinkler systems; extra-wide, pressurized stairwells; a dedicated set of stairwells exclusively for the use of firefighters; and biological and chemical filters throughout its ventilation system. The building is no longer 25 feet (8 m) away from West Street, as the Twin Towers were; at its closest point, West Street is 65 feet (20 m) away. The windows on the side of the building facing in this direction are equipped with specially tempered blast-resistant plastic, which looks nearly the same as the glass used in the other sides of the building. The 70 elevators and nine escalators for 1 World Trade Center will be provided by ThyssenKrupp, with steel counterweights supplied by Concord Steel. The Port Authority has stated: "Its structure is designed around a strong, redundant steel moment frame consisting of beams and columns connected by a combination of welding and bolting. Paired with a concrete-core shear wall, the moment frame lends substantial rigidity and redundancy to the overall building structure while providing column-free interior spans for maximum flexibility." In addition to optimum safety design, new security measures will also be implemented. All vehicles will be screened before they enter the site via the underground roadway, including for radioactive materials. Visitors to the National September 11 Memorial will furthermore undergo airport-style screening during the "Interim Operating Period", which is expected to end on December 31, 2013. 400 closed-circuit surveillance cameras will be placed in and around the site, with live camera feeds being monitored around the clock by the NYPD. A computer system will use video-analytic computer software designed to detect potential threats such as unattended bags and retrieve images based on descriptions of terror or other criminal suspects. New York City and Port Authority police will patrol the site. Once the World Trade Center site is fully completed, the plaza will be opened entirely to the public, as was the original World Trade Center.
