Engineering Bengaluru's underground transit future through hard granite terrain.
Namma Metro's Phase 2 underground extension required tunnelling through Bengaluru's notoriously difficult mixed-face granite geology. Cemindia's scope covered underground station civil works, TBM launch shafts, and cross-passage construction. The project demanded innovative drill-and-blast sequencing in dense residential areas with vibration monitoring to protect adjacent structures.
