Located in the Perth CBD, 581 Murray Street is a 20-storey residential tower currently under construction. The structure comprises post-tensioned concrete slabs with a centrally located in-situ core and precast concrete columns. We were engaged to deliver both structural and civil engineering services for the development.
A key feature of the structural design was the complete removal of the transfer structure initially included in the concept design. This decision allowed for a significant reduction in both material use and embodied carbon, aligning the project with improved sustainability metrics. The structural grid and vertical load paths were reconfigured to suit this approach without compromising the architectural layout or buildability.
We provided detailed coordination with the architect and builder to optimise the sequencing of the post-tensioned slabs and manage the integration of the precast elements. The use of a reinforced concrete core provided lateral stability while allowing flexibility in the floor plate layouts. Our civil design scope included stormwater management and site grading within a constrained urban footprint.
The result is a rationalised structure using a consistent grid system, streamlined vertical elements, and construction techniques selected for efficiency within a constrained city site.
