The Sydney Metro West project

Connecting Sydney’s major business districts with an underground railway

GBA: Mobility | Country: Australia

The Sydney Metro West project aimed to create a new underground railway line between Sydney’s two main business hubs: Parramatta and Sydney CBD. Plans were drawn up for twin 9km tunnels, excavations of two new metro stations, and a set of advanced maintenance facilities – all to be constructed as sustainably as possible.

Arcadis worked with our client GLC (Gamuda Australia and Laing O’Rourke Consortium) to identify ways of using its resources efficiently across each stage of the project, as well as optimizing infrastructure design. From integrating 100% renewable power across all operations, to using concrete mixes with up to 60% recycled content, to reducing overall material and energy useage, we played a pivotal role in minimizing environmental footprint. 

Achieving a 96-point ISC ‘Leading’ rating demonstrates the sustainable merit of our work. By reducing energy emissions by 43% and cutting embodied carbon emissions from materials by 25%, our collaboration helped shape a more well-connected and eco-friendly urban space.

Good consultants are hard to find, but brilliant ones, now that’s a rarity! Arcadis did an amazing job with the resource use credits and I hope to work with the team again in the future.
