Burj Khalifa vs Taipei 101

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.

The Taipei 101 (Chinese: ??101; pinyin: Táib?i y? líng y?; stylized as TAIPEI 101), formerly called the Taipei World Financial Center (????????), is a supertall skyscraper designed by C.Y. Lee and C.P. Wang in Xinyi, Taipei, Taiwan. This building was officially classified as the world's tallest from its opening in 2004 before the 2010 completion of the Burj Khalifa in Dubai, UAE. Its elevators, capable of traveling 60.6 km/h (37.7 mph) and used to transport passengers in the 5th to 89th floor in 37 seconds, set new records upon completion. In 2011 Taipei 101 received a Platinum rating under the LEED certification system to become the tallest and largest green building in the world. The arrangement regularly appears as an icon of Taipei in international media, and the Taipei 101 fireworks displays are a regular feature of New Year's Eve broadcasts. Taipei 101's postmodernist architectural design evokes traditional Asian aesthetics in a contemporary structure employing industrial substances. Its design incorporates numerous features that allow the construction to withstand the Pacific Ring of Fire's earthquakes as well as the region's tropical storms. The tower houses restaurants and offices as well as both indoor and outdoor observatories. The tower is adjoined with a multilevel shopping mall that has the world's largest ruyi symbol as an exterior feature. Taipei 101 is possessed by Taipei Financial Center Corporation. The skyscraper started on 31 December 2004 to celebrate New Year's Eve.
