The Worley Arcadis Joint Venture (JV) has been awarded the contract to deliver marine technical advisory services, which will be essential in the delivery of Westport, in Western Australia.
Westport is one of the largest infrastructure programs ever undertaken in Western Australia. Driven by the State Government, this project will aim to investigate, plan and build a future port in Kwinana, which will also integrate road and rail transport networks.
This program sets out to break down potential barriers presented by Western Australia’s current future container trade constraints, by relocating a portion of container trade from Fremantle to this new site in Kwinana.
The technical advisory services – to be delivered by the JV – will play an essential role in the definition and design of Westport.
The scope will support current definition activities including completion of reference designs and optimisation of infrastructure planning for the new port facilities, along with approvals, construction planning, and reliable costing ahead of final investment decisions.

A Westport Business Case was previously completed, showing significant risk to the Western Australian economy from future constraints on container trade if Westport was not built by the time Fremantle Port reaches capacity at the end of the 2030s.
The business case found inaction to address constraints on trade could cost WA’s economy $244 billion over coming decades – an average of $5 billion per year – driving significant increases in the costs of everyday household goods and for the State’s businesses.
Acting Transport Minister Dr Tony Buti said the new container port would be critical for the long-term strength of the Western Australian economy.
“This contract award marks a major milestone for Westport, bringing in the specialist marine design expertise needed for a once-in-a-century project to shape the future of container trade in the state,” Buti said.
