Mined Tunnels
Rock tunnels and caverns are an integral part of many major infrastructure projects as they are required for stations or bifurcations at underground road intersections.
Read moreMechanised Tunnels
It is common standard to use mechanised tunnels using Tunnel Boring Machines (TBMs) for the construction of underground structures, especially in urban environments.
Read moreCut & Cover Tunnels & Shafts
The design and construction of deep cut-and-cover boxes requires careful consideration of the construction sequence, the support systems and the interaction of the ground with the earth retaining structures and strutting arrangements.
Read moreGeotechnical Engineering
One of the most important aspects to a successful implementation of any tunnel project is obtaining detailed knowledge of the geology to be encountered and the geotechnical aspects associated with the required design.
