As the population grows in our cities and surface roads become more congested, tunnels are becoming an increasingly attractive option, for both public transport and private vehicles.

Melbourne Water Northern Sewerage Project, VIC

Our tunnelling team provides a one-stop-shop of specialist knowledge that includes planning, procurement and delivery of tunnelling infrastructure solutions.

We have bored tunnels in hard rock and soft ground, and have a strong understanding of segment lining, drill and blast tunnel excavation, trenchless methods, micro-tunnelling, pipe-jacking, shaft sinking in soft ground and rock and refurbishment of tunnels. 

We delivered the $2.5b Eastlink project, with our joint venture partners, Thiess. It was Australia's largest road infrastructure project, setting a new benchmark in safety and environmental management. Other key projects we have constructed are Airport Link in Brisbane, the Northern Sewerage project in Melbourne and we have recently completed the tunnelling works on Sydney Metro Northwest.

We have led the way and worked on the Australian Standard for Compressed Air, assisted with the development of the Tunnelling Code of Practice and assisted in the development of international tunnelling standards.
