Shaft

Shafts are commonly required on major infrastructure projects to provide early access to mined tunnels for opening several excavation fronts, or for bored tunnels to launch and retrieve the tunnel boring machine or simply to provide an escape or vent shaft.

What we offer is unique as our engineers are interdisciplinary experienced in the interaction of the walls, piles, strutting, dewatering (where required) as well as the construction sequence necessary to obtain sound and economic engineering solutions. That’s why we are known for our holistic and integrated design approach.

Our Expertise:

• Design of retaining structure using precast segments, bored piles, diaphragm, etc.
• Design of shotcrete and soil anchor support
• Control of ground movements and flow
