Cockburn Gateway Shopping City Stage 3
In this large suburban shopping complex, ASL used its proven top-down design technique to achieve build cost savings of 30% on traditional methods reducing capital costs from $106 million to $80 million - as well as yielding 4 months improvement on delivery of the project, enabling the Centre to be tenanted and trading by the Christmas period.
The design - construct proposal was fully validated by Quantity Surveyors, and assisted the Owners (Perron Group) in reassessing their reluctance to proceed with the project.
The project represents a landmark top-down construction project in Western Australia for several of Advanced Substructures' systems, including the patented Piles to Pillars system.
Estimate of conventional project cost of $106m to $112m made completion commercially unviable
