Burj Khalifa vs Trump International Hotel & Tower

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 Trump International Hotel and Tower is a skyscraper condo-hotel in downtown Chicago, Illinois.

The building, called for businessman and later U.S. president Donald Trump, was designed by architect Adrian Smith of Skidmore, Owings and Merrill. Bovis Lend Lease constructed the 98-story structure, which reaches a height of 1,388 ft (423.2 m) including its spire, its roof topping out at 1,171 ft (357 m). It's next to the main branch of the Chicago River, with a view of the entrance to Lake Michigan past a series of bridges across the river. The building received publicity once the winner of the first season of The Apprentice reality television show, Bill Rancic, chose to handle the construction of the tower over handling a new Trump National Golf Course and resort in Los Angeles. Trump announced in 2001 that the skyscraper would become the tallest building in the world, but following the September 11 attacks that same year, the architects scaled back the building's plans, and its design underwent several revisions. When topped out in 2009, it turned into the second-tallest construction in the U.S.. It surpassed the city's John Hancock Center as the construction with the maximum residence (apartment or condominium ) in the world, and held this title until the conclusion of the Burj Khalifa. The design of the building includes, from the bottom up, retail space, a parking garage, a hotel and condominiums. The 339-room hotel opened for business with limited accommodations and services on January 30, 2008, then full lodging and services on April 28. The construction topped out in late 2008 and construction was finished in 2009. Sixteen was one of five restaurants in Chicago with a Michelin Guide two-star evaluation in 2016 and one of three five-star Forbes-rated restaurants in town until it closed in 2018. The spa is one of six with a four-star Forbes score in the Chicago area in 2015.
