Shanghai World Financial Center vs One World Trade Center

Informations

The Shanghai World Financial Center (SWFC; Chinese: ????????) is a supertall skyscraper located in the Pudong district of Shanghai. It was designed by Kohn Pedersen Fox and developed by the Mori Building Company, with Leslie E. Robertson Associates as its structural engineer and China State Construction Engineering Corp and Shanghai Construction (Group) General Co. as its primary contractor. It is a mixed-use skyscraper, comprising offices, hotels, conference rooms, observation decks, and ground-floor shopping malls. Park Hyatt Shanghai is the tower's hotel element, comprising 174 rooms and suites occupying the 79th to the 93rd floors, which at the time of completion was the highest hotel in the world. It is currently the third-highest hotel on earth after the Ritz-Carlton, Hong Kong, which occupies floors 102 to 118 of the International Commerce Centre.

On 14 September 2007, the skyscraper was topped out and is 492 meters (1,614.2 feet ), which makes it the 12th tallest building in the world and the fourth tallest structure in Mainland China. The SWFC opened to the general public on 28 August 2008, with its observation deck opening on 30 August. The observation deck offers views from 474 m (1,555 feet ) above ground level.The SWFC was lauded for its design, and in 2008 it was named by architects as the year's best-completed skyscraper. In 2013, the SWFC was exceeded in height by the adjoining Shanghai Tower, which will be China's tallest structure as of 2017. Collectively, The Shanghai World Financial Center, The Shanghai Tower and The Jin Mao Tower form the world's first adjoining grouping of three supertall skyscrapers.

One World Trade Center (also known as One World Trade, 1 WTC, or Freedom Tower) is the main building of the rebuilt World Trade Center complex in Lower Manhattan, New York City.

1 WTC is the tallest building in the United States, the tallest building in the Western Hemisphere, and the sixth-tallest in the world. The supertall structure has the identical title as the North Tower of the original World Trade Center, which was destroyed in the terrorist attacks of September 11, 2001. The new skyscraper stands on the northwest corner of this 16-acre (6.5 ha) World Trade Center site, on the website of the original 6 World Trade Center. The building is bounded by West Street to the west, Vesey Street to the north, Fulton Street to the south, and Washington Street to the east. The building's architect is David Childs, whose firm Skidmore, Owings & Merrill (SOM) also designed the Burj Khalifa and the Willis Tower. The construction of below-ground utility relocations, footings, and foundations for the new building began on April 27, 2006. One World Trade Center became the tallest construction in New York on April 30, 2012, as it surpassed the height of the Empire State Building. The tower's steel structure was topped out on August 30, 2012. On May 10, 2013, the last component of this skyscraper's spire was set up, which makes the building, including its spire, reach a whole height of 1,776 feet (541 m). Its elevation in feet is a deliberate reference to the year when the United States Declaration of Independence was signed. The building opened on November 3, 2014; the 1 World Observatory opened on May 29, 2015. On March 26, 2009, the Port Authority of New York and New Jersey (PANYNJ) confirmed that the building would be officially known by its legal name of'One World Trade Center', rather than its colloquial name of'Freedom Tower'. The building is 104 standard floors high, but the tower has just 94 real stories. The new World Trade Center complex will eventually contain five high-rise office buildings built along Greenwich Street, in addition to the National September 11 Memorial & Museum, located just south of One World Trade Center where the original Twin Towers stood. The construction of the new building is part of an effort to memorialize and rebuild following the destruction of the original World Trade Center complex.
