Suburban Rail Loop East – Monash

Project: Suburban Rail Loop East – Monash

Principal Contractor: CPB Contractors and ACCIONA

The Suburban Rail Loop East is Victoria’s largest transport infrastructure project, connecting Melbourne’s middle suburbs via a new 26-kilometre underground rail line from Cheltenham to Box Hill. The new Monash Station will be located at the corner of Normanby and Howleys Roads, delivered as part of the AU$3.6 billion tunnelling and station package by the Suburban Connect consortium of ACCIONA, CPB Contractors and Ghella. Early works to relocate utilities, modify road intersections and construct tunnel access structures were completed in 2025, with main works commencing in April 2026 to establish the construction site for station building and tunnel boring activities. Tunnel boring is expected to begin in early 2027, progressing north beneath Monash University’s Clayton campus, with the station serving the University, CSIRO, the Australian Synchrotron and the wider Monash Technology Precinct from 2035.

Key aspects of the project include:

• Construction of a new underground Suburban Rail Loop station at the corner of Normanby and Howleys Roads
• Relocation of underground utilities and construction of tunnel access structures ahead of main works
• Tunnel boring progressing north beneath Monash University’s Clayton campus from 2027
• Delivery by the Suburban Connect consortium of ACCIONA, CPB Contractors and Ghella

HCS is engaged on the project to provide Underground Service Locating services.
