Office building in Perth (Central Park)

Building use

Office building

Country/Region

Australia

Overview

This building utilised high strength steel sections encased in concrete. This allowed steel beams to be connected to the steel columns.

Basic information (construction date, number of stories, gross floor area, adopted design code, engineer(s), Contractor(s), etc.)

Construction date: 1992
Number of stories: 51
Gross floor area: 66,500m2
Adopted design code: AS1250/AS2327.1 (Standards Australia, 1990 and 1980)
Engineer(s): Bruechle, Gilchrist & Evans
Contractor(s): Multiplex

Issue and/or innovation

The building utilised encased high strength steel sections. This involved the use of high strength quenched and tempered structural steel of yield stress of 690 MPa (N/mm2) being used for encased struts.

Specific solution/technical details

This building utilised high strength steel sections encased in concrete. This allowed steel beams to be connected to the steel columns. The steel columns and beams thereby promoted off site fabrication and significantly improved construction speed. Furthermore, precast concrete slabs were placed between steel beams, further adding to the rapid nature of construction. Over 60,000 m2 of precast concrete floor units were used in this project, making it the largest precast supply to an Australian construction company and project.

Impact or effectiveness

Central Park is the tallest building in Perth and the 14th tallest in Australia.
