Metro Tunnel Project

The Metro Tunnel Project is a city-shaping project for Melbourne and Victoria. The project includes the construction of twin nine-kilometre rail tunnels and five new underground stations. When complete, the Metro Tunnel will untangle the City Loop and create a new end-to-end rail line across Melbourne. The approved budget for the project is $12.4 billion.

CYP Design & Construction – a joint venture comprising John Holland, Lendlease Melbourne Metro and Bouygues Construction Australia are delivering the tunnels and stations package for the Metro Tunnel Project.

The Challenge

The Metro Tunnel is one of the largest transport infrastructure projects ever undertaken in Australia. It is complex and multi-faceted. Our client, CYP Design & Construction, required a comprehensive range of spatial services from a service provider that could meet the large resourcing demands, as well as deliver specialist expertise to overcome a range of technical challenges.

Our Solution

The multi-disciplinary expertise of Veris, combined with our capacity to flex resources to meet project requirements, has enabled us to deliver an array of in-house services across the life cycle of the project.

Cadastral Survey and Consulting

In the project’s early stages, our team provided cadastral consulting and land tenure advice with the preparation of plans and documentation required for land acquisitions and crown allotment creation. This role required extensive engagement with the Office of the Surveyor General (OSG), local governments, Rail Projects Victoria (RPV) and CYP to enable the most efficient and cost-effective outcomes for a challenging project.

Engineering Survey

Our team have been responsible for delivering all aspects of engineering survey for the project’s CBD precincts, which include the Town Hall and State Library stations. These works have involved:

  • Initial excavation of five shafts, eight connecting adits, central caverns, and platform tunnels
  • Managing the tunnel guidance network of eight roadheaders utilising VMT software
  • The building of two top down OSD construction sites
  • Final structures and lining of the stations.

To perform the works, we have provided a workforce of up to 30 surveyors for the CBD precincts, utilising 12D and synergy for all design set out and as-built data capture.

Control and Audit Survey

We designed, installed, and maintained a high order primary survey control network throughout the project extents. To complete a control network of such scale it was necessary to utilise GNSS, TPS and differential levelling techniques. The high-order control network developed by Veris has since been adopted and registered with the Office of the Surveyor General as an asset for all Victorian survey professionals to utilise into the future.


To monitor and protect significant infrastructure and buildings given the large-scale nature of project construction, our team have deployed a range of bespoke monitoring solutions. This includes automated monitoring of critical road infrastructure including tunnels and freeways, deformation monitoring of historic CBD buildings, construction zones, as well as quarterly subsidence monitoring. A 3D laser scanning solution was also deployed in the station’s central caverns to provide monitoring during platform construction.


The Metro Tunnel Project is planned to open in 2025. To support the ongoing delivery of the tunnels and stations main works package, our team has supported outcomes including:

  • Schedule milestones - our capacity to flex resources to meet the needs of such a large-scale project has supported schedule milestones
  • Reduced interfaces - our ability to offer an integrated spatial solution has minimised the need to source other specialist service providers
  • Safety and efficiency - the use of innovative technologies including 3D scanning and automated monitoring have provided significant safety and efficiency outcomes.
