Case Studies

Here's a sample of some recent programs and initiatives happening around our company in sustainability, safety, broader social outcomes, and digitial engineering.

Tunnel Boring Machines

McConnell Dowell tunnels have provided the means to alleviate traffic congestion, extend rail networks, generate sustainable hydropower, unlock precious resources and sustain communities through new clean water supplies.

We have delivered over 140 km of safe, smart, efficient tunnels and underground spaces while minimising community and environment impact.

Our skill is in selecting the right technology and approach to suit each project’s unique requirements.
We have engineered solutions using tunnel boring machines (TBM), road headers, drill and blast, pipe-jacking, micro-tunnelling and horizontal directional drilling (HDD).

Our strong relationships with key equipment suppliers mean we mobilise quickly and begin construction on time. Our standard practice is to coordinate underground and above-ground activities to minimise any inconvenience to businesses, residents and traffic.

We broke TBM tunnelling world records during the Blue Mountains Sewerage Scheme, completed the longest pipejack in the Southern Hemisphere on the Pringle Hill NNA Pipeline, and are the only contractor in the Southern Hemisphere to have performed three successful TBM marine recoveries.

Looking to the future, we are driving progress in the resources sector through the safe, compliant and efficient delivery of mine access drives using rapid advance, full-face tunnelling technology.
