Cockburn Gateway Shopping City Stage 3

Advanced Substructures were invited by the Architect to conduct a Value Engineering redesign of this large suburban shopping complex to overcome the client’s reluctance to proceed. Initially valued at $106 million, the client was aiming at a reduction of costs of at least $10 million.

The alternative 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 our 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

Impact of construction on service routes

Key Challenges

No impact on trading of existing Centre, buildings, services, transport
