The Aspire Tower is a 300 metres (984 ft) tall tower-like skyscraper located in the Doha Sports City complex in Doha, Qatar. Designed by architect Hadi Simaan and AREP and engineer Ove Arup and Partners,^[1] the tower served as the focal point for the 15th Asian Games hosted by Qatar in December 2006.

The Aspire Tower is currently the tallest structure and building in Doha and Qatar, but it is expected to be surpassed by the Dubai Towers Doha and the Barwa Tower. The tower has also been known as Khalifa Sports Tower, Doha Olympic Tower or the Torch.

Construction and use

The tower was a landmark of the 2006 Asian Games due to its size and proximity to the main venue, the Khalifa International Stadium. The tower housed the Asian Games flame during the games and holds the record for tallest ever games flame and highest positioning of a games flame, which was visible throughout Doha for the duration of the games. The design employs a concrete core which acts as the primary support. The remainder of the building is a steel structure that cantilevers out from the concrete core. The exterior of the building is covered in a steel mesh which, during the Asian Games, was festively illuminated by vibrant LED lights.

The final form consists of a 1-to-1.8 metre thick, reinforced-concrete cylinder (the core), varying from 12 to 18 metre in diameter, encircled with radiating networks of cantilevered steel beams on each floor of its building modules. The modules themselves are composed of steel columns, metal decking, concrete slabs, and outer tension and compression ring beams, which support glass-paneled outer walls. The bottom of each module is covered with glass-fiber-reinforced concrete. Beams, as well as steel struts tying all the structural components together, are bolted through the concrete core and hence are anchored into place, transferring vertical loads from perimeter columns and ring beams to the core.^[2]

The designer, Simaan, has described the structure as "a celebration of earth and sky" adding that, "the structural steel struts that brace the structure back to the core also act as visual forces which create energy radiating from the center in a centrifugal rise." One of the most interesting features of the tower is the broadcast of videos which was carried out around an 8 metre section of the tower; this was done through the use of Philips technology.

The building was fully completed in November 2007 at a final cost of €133,395,000.
