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.

The Pentagon is the headquarters building of the United States Department of Defense.

As a symbol of the U.S. military, the phrase The Pentagon is also often used as a metonym for the Department of Defense and its leadership. Located in Arlington County, Virginia, across the Potomac River from Washington, D.C., the building was designed by American architect George Bergstrom and constructed by contractor John McShain. Ground was broken on 11 September 1941, and the building was dedicated on 15 January 1943. General Brehon Somervell supplied the important motivating power behind the project; Colonel Leslie Groves was responsible for overseeing the project for the U.S. Army. The Pentagon is the world's largest office building, with about 6,500,000 sq feet (600,000 m2) of space, of which 3,700,000 sq feet (340,000 m2) are used as offices. Some 23,000 military and civilian employees, and another 3,000 non-defense support employees, work in the Pentagon. It has five sides, five floors above ground, two basement levels, and five ring corridors per floor with a total of 17.5 mi (28.2 km) of corridors. The fundamental five-acre (20,000 m2) pentagonal plaza is nicknamed'ground zero' on the presumption that it would be a prime target in a nuclear war.On 11 September 2001, exactly 60 years after the building's construction began, American Airlines Flight 77 was hijacked and flown into the western side of the building, killing 189 people (59 victims and the five terrorists on board the airliner, as well as 125 victims in the building), according to the 9/11 Commission Report. It was the first major foreign attack on Washington's governmental facilities since the town was burned by the British during the War of 1812. The Pentagon is listed on the National Register of Historic Places and is a National Historic Landmark.
