Tunnels play a critical role in the ongoing delivery and maintenance of the transport infrastructure required to support our modern world.



Supporting the growth of our communities through the delivery and maintenance of state-of-the-art tunnels and tunnel systems

Tunnels play a critical role in the ongoing delivery and maintenance of the transport infrastructure required to support our modern world. As well as connecting communities, our road and rail tunnels provide pivotal links to support ongoing population growth by allowing people and freight to move more freely across our road and transport networks.

Tunnelling often presents significant engineering challenges requiring practical knowledge, technical skills and commitment to achieve fruitful project outcomes – and, at Aurecon, our tunnel consultants are committed to overcoming these challenges.

Our difference

Our technical engineering specialists unite to offer an integrated service.

The depth of our tunnelling experience, and the size of our team, means we are able to successfully deliver on major projects through each stage of the project lifecycle – from pre-construction, right through to construction and asset management.

Our specialised and multidisciplinary team of tunnel consultants can design and deliver tunnels and tunnel systems in complex environments, utilising experience across multiple disciplines, including geotechnical, drainage, fire systems, sustainability, structures, mechanical and electrical engineering.

An integrated solution

Our tunneling capabilities include:

  • Rock and soft ground tunneling
  • Tunnel mechanical and electrical (M&E) systems
  • Specialist design
  • Materials engineering
  • Tunnel maintenance and refurbishment
  • Geotechnical services
  • Tunnel survey, geometry and visualisation
  • Foundation and excavation support/retention systems design
  • Drill and blast
  • Digital engineering and advisory
  • Understanding and controlling ground water
  • Construction programming

We are dedicated to pioneering tunnel design and have our finger on the pulse when it comes to new technology. We use advanced 2D/3D continuum and discontinuum computer modelling, as well as traditional and practical engineering design methods.

Our internationally renowned engineering experience is exemplified through a diverse portfolio of ambitious tunnelling projects that demonstrate our abilities in design and geotechnical, to design creative and effective solutions, with a user-led approach.

Supporting essential infrastructure

The tunnels we design for our cities and regional areas are successful examples of our state-of-the-art engineering expertise; creating more integrated networks. They are the legacy we continue to leave.

Our tunnel infrastructure experience includes:


Rail and mass transit

Aurecon has a strong understanding of the business and economic fundamentals of successful rail and mass transit projects that involve major tunnels. We ensure we understand the specific business operations requirements and success factors and incorporate them into the design, planning and project delivery of rail and mass transit tunnelling projects.

Energy and resources

Aurecon focuses on assisting energy and resources clients through tailored solutions that will increase direct operating hours, improving reliability and reduce maintenance through operational design solutions, including tunnelling techniques for energy and resources projects.

Underground space

To meet continuous population growth, governments are increasingly looking to underground space to free valuable land. Underground space requires complex networks of tunnels and large span caverns. Aurecon’s extensive experience designing caverns in excess of 20m span allows us to be at the forefront of the storage revolution.

Immersed tunnelling shaping Sydney's transport network

Sydney Harbour Tunnel

A look into how immersed tube tunnelling is shaping the Sydney's transport network.

As we approach the 30-year anniversary of the iconic Sydney Harbour Tunnel we are also imagining what Australia’s second immersed tube tunnel will mean for the city’s transport network.

Light rail and mass transit

Flexing the rail network

Around the world, governments are using light rail and mass transit to improve connectivity and reshape cities.

As cities grow and public expectations for low-carbon transport options increase, light rail and other forms of mass transit are experiencing a resurgence.
