Shanghai Tower

The Shanghai Tower is a 632-metre (2,073 ft), 128-story megatall skyscraper in Lujiazui, Pudong, Shanghai. As of 2015, it is the world's tallest building, by height to highest usable floor (Level 127, 587.4 m). It also has the world's highest observation deck within a building or structure (Level 121, 561.25 m), and the world's fastest elevators at a top speed of 20.5 m/s (74 km/h). It is the world's second-tallest building by height to architectural top (behind Dubai's Burj Khalifa, 828 m) and the world's third-tallest structure (behind Tokyo Skytree, 634 m).

Designed by international design firm Gensler and owned by the Shanghai city government, it is the tallest of the world's first triple-adjacent super-tall buildings in Pudong, the other two being the Jin Mao Tower and the Shanghai World Financial Center. Its tiered construction, designed for high energy efficiency, provides nine separate zones divided between office, retail and leisure use.

Construction work on the tower began in November 2008 and topped out on 3 August 2013. The exterior was completed in summer 2015, and work was considered complete in September 2015. Although the building was originally scheduled to open to the public in November 2014, the actual public-use date slipped considerably. The observation deck was opened to visitors in July 2016; the period from July through September 2016 was termed a "test run" or "commissioning" period.

Planning and Funding :

Planning models for the Lujiazui financial district dating back to 1993 show plans for a close group of three supertall skyscrapers. The first of these, the Jin Mao Tower, was completed in 1999; the adjacent Shanghai World Financial Center (SWFC) opened in 2008.

The Shanghai Tower is owned by Yeti Construction and Development, a consortium of state-owned development companies which includes Shanghai Chengtou Corp., Shanghai Lujiazui Finance & Trade Zone Development Co., and Shanghai Construction Group. Funding for the tower's construction was obtained from shareholders, bank loans and Shanghai's municipal government. The tower had an estimated construction cost of US$2.4 billion.

Burj Khalifa

The Burj Khalifa known as the Burj Dubai before its inauguration, is a mega tall skyscraper in Dubai, United Arab Emirates. It has a roof height of 828 m (2,717 ft), and with its antenna included, it stands a total height of 829.8 m (2,722 ft), making it the tallest building and the tallest structure in the world.

Construction of the Burj Khalifa began in 2004, with the exterior completed 5 years later in 2009. The primary 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 centre piece of large-scale, mixed-use development. The decision to build the building is reportedly based on the government's decision to diversify from an oil-based economy, and for Dubai to gain international recognition. The building was named 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 tower in the world.

Burj Khalifa was designed by Adrian Smith, then of Skidmore, Owings & Merrill (SOM), whose firm designed the Willis Tower and One World Trade Center. Hyder Consulting was chosen to be the supervising engineer with NORR Group Consultants International Limited chosen to supervise the architecture of the 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 space. An innovative buttressed central core and wings are used to support the height of the building. Although this design was derived from Tower Palace III, the Burj Khalifa’s central core houses all vertical transportation with the exception of egress stairs within each of the wings. The structure also features a cladding system which is designed to withstand Dubai's hot summer temperatures. It contains a total of 57 elevators and 8 escalators.

Critical reception to Burj Khalifa has been generally positive, and the building has received many awards. However, the labour issues during construction were controversial, since the building was built primarily by migrant workers from South Asia with several allegations of mistreatment. Poor working conditions are rife as the result of the lack of minimum wage laws in the United Arab Emirates. Several instances of suicides have been reported, which is not uncommon for migrant construction workers in Dubai despite safety precautions in place.

Development :

Construction began on 6 January 2004, with the exterior of the structure completed on 1 October 2009. The building officially opened on 4 January 2010, and is part of the new 2 km2 (490-acre) development called Downtown Dubai at the 'First Interchange' along Sheikh Zayed Road, near Dubai's main business district. The tower's architecture and engineering were performed by Skidmore, Owings and Merrill of Chicago, with Adrian Smith as chief architect, and Bill Baker as chief structural engineer. The primary contractor was Samsung C&T of South Korea. The tower's construction was done by the construction division of Al Ghurair Investment group.
