Informations

The Burj Khalifa (Arabic: ??? ?????, Arabic pronunciation: [b?rd?? xa?li?fa]; pronounced English: ), known as the Burj Dubai prior to its inauguration in 2010, is a skyscraper in Dubai, United Arab Emirates. With a total height of 829.8 m (2,722 feet, just over half a mile) and a roof height (excluding antenna, but such as a 244 m spire) of 828 m (2,717 feet ), the Burj Khalifa has been the tallest structure and building in the world since its topping out in 2009 (preceded by Taipei 101).Construction of the Burj Khalifa began in 2004, with the exterior finished five decades later in 2009. The principal structure is reinforced concrete. The building was opened in 2010 as part of a new development called Downtown Dubai. It is designed to be the centrepiece of large-scale, mixed-use development. The decision to construct the building relies on the government's decision to diversify from an oil-based economy, and for Dubai to obtain international recognition. The building was originally named Burj Dubai but was renamed in honour of the ruler of Abu Dhabi and president of the United Arab Emirates, Khalifa bin Zayed Al Nahyan; Abu Dhabi and the UAE government lent Dubai money to pay its debts. The building broke numerous height records, including its designation as the tallest building in the world. Burj Khalifa was designed by Adrian Smith, of Skidmore, Owings & Merrill, whose firm designed the Willis Tower and One World Trade Center. Hyder Consulting was selected to be the supervising engineer with NORR Group Consultants International Limited selected to supervise the architecture of this project. The design is derived from the Islamic architecture of the region, such as in the Great Mosque of Samarra.



The Y-shaped tripartite floor geometry is designed to optimize residential and hotel room. A buttressed central core and wings are utilised to support the elevation of the building. Although this design was derived from Tower Palace III, the Burj Khalifa's central center homes all vertical transport with the exception of egress stairs within each of the wings. The structure also offers a cladding system which is designed to withstand Dubai's hot summer temperatures. It comprises a total of 57 elevators and 8 escalators. At a particular stage in the architectural and engineering process, the original Emaar programmers experienced financial problems, and required more money and financial funding. Sheikh Khalifa, the ruler of the United Arab Emirates, granted monetary aid and financing, hence resulting in the changing of the name to'Burj Khalifa'. The concept of profitability derived from creating high density developments and malls around the landmark have proven effective. Its surrounding malls, hotels and condos in Downtown Dubai have generated the most revenue from the project as a whole, while the Burj Khalifa itself made little or no profit.Critical reception to Burj Khalifa has been generally positive, and the building has received many awards. However, there were numerous complaints regarding migrant workers from South Asia who were the key building labor force. These centered on low wages and the practice of confiscating passports until duties were complete. Several suicides were reported.

Informations

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.
