Investment in Victoria’s infrastructure and urban planning is making way for growing economic precincts outside of Melbourne’s CBD. The Suburban Rail Loop (SRL) will better connect Victorians, slash travel times and ensure the city grows in the right places.

When completed, the 90km SRL will transform Victoria’s public transport system, linking every major rail line from the Frankston line to the Werribee line, via the airport, ensuring Melbourne remains one of the world’s most livable cities.

The project will be delivered in stages over several decades, with SRL East the first to be constructed. Future SRL sections to be developed include SRL North (Box Hill to Melbourne Airport), SRL Airport (Melbourne Airport to Sunshine), and SRL West (Sunshine to Werribee).

SRL East will include 26km of twin tunnels, a train maintenance facility and six underground stations from Cheltenham to Box Hill. Since 2018, WT’s been working closely with Suburban Rail Loop Authority (SRLA) providing cost advisory services across the Tunnelling, Stations, Linewide and Rolling Stock packages. We support the project with whole-of-life cost estimation, cost planning, value engineering, probabilistic risk modelling, tender evaluation and negotiation, and project controls services.

Leveraging digital solutions including Building Information Modelling (BIM), we deliver accurate cost estimates and present our cost reports through bespoke, interactive reporting portals tailored to SRLA’s needs.

With our deep understanding of the project scope, methodology and documentation, we have been able to provide consistency of information and reporting, underpinned by extensive cost data and benchmarking.

We also support SRLA with portfolio and program advisory, ensuring projects and project activities are aligned with strategic goals, are feasible and well-managed from a risk, cost and schedule perspective.

Construction of SRL East started in 2022, with works now powering ahead at all six stations sites. Planning is well underway to ensure the neighborhoods around these stations are vibrant and thriving communities for generations to come, and we’re proud to be a part of this city-defining project.
