Tunnel excavation requires lots of technical skills, professional and experienced workers and sophisticated machinery.
Tunnels are excavated for various reasons and purposes such as building underground, railways, mining operations, laying pipelines etc.
The method of tunnel construction depends mainly on the following factors:
The general ground conditions, the tunnel depth, the logistics of supporting the tunnel excavation, the diameter, and length of the tunnel drive, but also the final use and shape of the tunnel, including the tunnel construction safety, risk assessment, and management.
