We’re Australia’s leading tunnelling contractor responsible for delivering projects across the transport and utility sectors in Australia, New Zealand and South East Asia. Our tunnelling experience dates back to 1958, when we were the first Australian company to be awarded major construction projects on the Snowy Mountains Hydro Electric Scheme.  

From hard rock to flowing sands, our diverse tunnelling, underground excavation and associated civil works experience enables our people to develop innovative solutions that safely and successfully deliver projects of long-term value.
