Cut and cover tunnels are technically and economically optimal for tunnelling at shallow water depths in urban areas.
Cut and cover tunnels at low depth have been used worldwide for centuries. However, new technologies now allow the use of cut and cover technology at increasing depths and very close to, or even under, existing tall buildings.
In locations with no important constraints on the surface, cut and cover tunnels are inexpensive compared to other tunnelling techniques. Approaches to immersed or bored tunnel sections will often be constructed as cut and cover tunnels.
COWI UK Limited's design of cut and cover tunnels is supported by intensive use of software developed in-house for all design phases:
Several construction techniques exist and will be chosen depending on the ground conditions, the space available and environmental requirements.
