Capita Centre
From Wikipedia, the free encyclopedia
Capita Centre is a skyscraper in Sydney, Australia. Located at 9-11 Castlereagh Street, it is 183 m tall from spire and 158 m tall from roof. The building was designed by Harry Seidler & Associates. The structural engineer was Miller, Milston & Ferris and the builder was Civil & Civic. Completed in 1989 at the cost of $200 m, the building is primarily used as a commercial office tower.
The Capita Centre is rectangular and consists of 34 levels, with a total floor area of 24,450 m². The building is constructed of composite structural steel and concrete, with its support structures making it unique as it wears its structure on the outside as an outer skeleton. The external columns or lateral bracing truss are unique because they exist outside the core of the building.
