Tunneling in limestone rock using TBM method for MRT projects near cochrane station

Tunnel construction in Kuala Lumpur area are to be build due to the increasing traffic congestion in urban areas and increasing land price. Underground structure like tunneling can preserve the land above while providing a route for Mass Rapid Transport (MRT) line for transportation. MRT line in Kua...
