UNIQA PS1 - Ein Hochhaus aus Stahl

UNIQA PS1 a high rise building made from steel.

From September 2008 to July 2009 the steel construction of a high rise building was erected in Vienna. A 13-storey tower floats above an air-space with 30 m height and 27 m width. The main carrying structure consists of a latticed framework which is integrated into the walls. The connection between the steel construction and the concrete structure was an ambitions task for the structural team of the client UNIQA, consisting of Werner Consult Ziviltechniker GesmbH and Zivilingenieurbüro Roller. Detail engineering, fabrication and erection was executed by ARGE Stahlbau PS1 consisting of Zeman and Strabag. The order was won amongst other reasons because of an innovative erection procedure. The two lowest floors were pre erected on the ground floor and the approximately 1600 tons lifted into the final position on 30 m afterwards. It was only possible to complete this task on time and in budget due to the intensive cooperation between the partners from the steelworks and the concrete works.
