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.
In urban centers and airports, the underground builds of transit systems must be planned to minimize surface disruption throughout the construction process. We provide the geotechnical, structural, and tunneling skills you need, and complement them with track design, signaling, communications, traction power, ventilation and emergency egress, rail activation, and systems commissioning.
