Résumé
The Costanera Center Torre 2, better known as Gran Torre Santiago (Great Santiago Tower), and previously known as Torre Gran Costanera, is a 62-story skyscraper in Santiago, Chile. It is the tallest building in South America, the second tallest building in Latin America (behind Mexico's T.Op Torre 1) and the fifth tallest building in the Southern Hemisphere (behind Indonesia's Autograph Tower and Luminary Tower, and Australia's Q1 Tower and Australia 108). The tower was designed by Chilean architects Alemparte Barreda & Asociados, the Argentine architect César Pelli and the Canadian company Watt International.
Gran Torre Santiago is part of the Costanera Center complex, which includes the largest shopping mall in Latin America, two hotels and two additional office towers. Gran Torre Santiago is tall and 64 storeys high plus 6 basement floors, with a floor pitch of and in area.
The tower has nearly 700,000 square meters of building space available built on 47,000 square meters of land. Planners estimated that there would be some 240,000 people going to and from the site each day.
The tower was designed by Chilean architects Alemparte Barreda & Asociados, the Argentine architect Cesar Pelli of Pelli Clarke Pelli Architects, and by the Canadian company Watt International. Structural engineering is performed by the Chilean company René Lagos y Asociados Ing. Civiles Ltda. Salfa Corp. was responsible for its construction.
Pelli would use a similar design in the San Francisco's Salesforce Tower.
Construction of the building began in June 2006 and was expected to be completed in 2010, but was put on hold in January 2009 due to the global financial crisis of 2008–2009. Construction on the project resumed on 17 December 2009.
In early November 2010, standing tall, it overtook the neighboring Titanium La Portada to become the tallest building in Chile. In February 2011, La Segunda daily reported that, at tall, the tower had overtaken Caracas's Twin Towers to become the tallest building in South America, while La Tercera newspaper reported in February 2012 that it had achieved that feat on 12 April 2011.
