Consulting engineers specialising in bridge, tunnel, marine and specialist engineering
COWI experience in designing tunnels and shafts to be constructed using drill and blast techniques, covers a range of sizes, from small diameter up to large span caverns.
The design of drill and blast tunnels requires detailed understanding of the geology through which the tunnel is to be driven. The behaviour of the rock mass due to slope excavation, has to be modelled and effective tunnel support designed. Optimal support is achieved by reinforcing the inherent strength of the rock mass.
COWI UK Ltd uses expertise gained over many years working underground in hard rock, together with sophisticated numerical analysis to develop optimal designs.
Our site staff have extensive experience in working with contractors to implement designs for temporary and permanent rock support.
