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

Impact of construction on trading of existing centre (disruption of potential closure time, car-bays, services and other features)

Impact of construction on adjoining non-centre buildings and services
