Yesterday evening, a Tunnel Boring Machine (TBM) operated by the FEMC-Pratibha JV for contract CC-18 of Delhi Metro’s Phase 3 project made a second breakthrough at the Sarojini Nagar station! The TBM started boring from the Bhikaji Cama Place station and traveled 1105m while building 790 rings for the 58.596 km Pink line’s up-line tunnel.
