In a first for the Namma Metro project, Tunnel Boring Machine (TBM) Urja drilled a distance of 27 meters on April 25. The machine is currently deployed between Cantonment and Pottery Town.
There are nine TBMs deployed to build a tunnel network for a distance of 14 km under the phase II of Namma Metro project. Usually, each TBM bore a distance of maximum of six meters in a day, but Urja outperformed them all by drilling a distance of 27 meters.
