Sydney Metro Northwest

Sydney, New South Wales, Australia - The first stage of Sydney Metro, a fully automated metro railway delivering 31 new stations from Tallawong in Sydney’s North West, through to Bankstown in the city’s South, and more than doubling the capacity of Sydney’s rail network.

8

new railway stations

15

trains per hour

The first fully automated metro rail system in Australia, with trains running every four minutes.

Sydney Metro Northwest delivers eight new railway stations to Sydney’s growing North West, and twin 15km tunnels between Epping and Bella Vista. With trains running every four minutes, this turn up and go service is providing reliable public transport service to a region which has the highest car ownership levels per household in NSW. 

Arcadis provided design and construction phase services to the D&C Joint Venture Contractor comprised of CPB, John Holland, and Dragados for the Tunnels and Stations Civils works (TSC). 

Arcadis’ responsibilities included the detailed design of the deep excavation supports at each underground station, and the associated surface civil works, including temporary structures, enabling the rapid deployment of tunnel boring machines which in turn enabled construction to finish well ahead of schedule.

In association with APP, Arcadis also provided Independent Certification services for the Stations, Viaducts, and Civil Works (SVC) between Bella Vista and Cudgegong Road. This section of the Metro Northwest includes an elevated viaduct structure between Bella Vista and Rouse Hill, and Arcadis’ role encompassed supporting the on time delivery of the design and construction phase by ensuring quality, durability, and safety compliance with the SVC contractor, Impregilo, Salini JV (ISJV).

Leading Construction Sustainability

A key focus of the Sydney Metro Northwest project has been sustainability, with a range of sustainable initiatives being employed throughout construction.

As a result of this focus, which saw the reuse of 100% of the 4.3 million tonnes of crushed rock and excavated material generated from tunneling, and a reduction in water use of 66%, the twin 15km tunnels were awarded the highest possible rating for sustainability by the Infrastructure Sustainability Council of Australia (ISCA).

At Arcadis, we’re proud of the innovative concept to recycle the recently decommissioned Sydney Monorail superstructure as bridge girders for the temporary bridge at the Norwest Station site, another significant sustainability achievement.
