L&T’s 1st Patna Metro TBM Passes Factory Tests
China Railway Construction Heavy Industry Co. Ltd. (CRCHI) has completed factory acceptance tests (FAT) on the 1st of 2 new tunnel boring machines for the 30.91 km Patna Metro Phase 1 project’s underground section.
This TBM will be deployed by Larsen & Toubro along with 3 other machines on 14.05 km Line-2’s 8 km Rajendra Nagar – Patna Junction Railway Station section (Package PC-03).
Delhi Metro Rail Corporation (DMRC) had awarded L&T with package PC-03’s Rs. 1989 crore contract in December 2021 with a 42 month deadline.
PC-03 will connect a ramp near Rajendra Nagar with Patna Junction Railway Station through TBM bored twin tunnels and 6 underground stations at Akashvani (formerly Dak Bungalow), Gandhi Maidan, PMCH, Patna University, Moin Ul Haq Stadium, Rajendra Nagar.
Besides 2 CRCHI machines, L&T will deploy 2 THI machines (S71 & S72) previously used for Ahmedabad Metro Phase 1’s tunneling where a final breakthrough was recorded in August 2020.
L&T’s tunneling plan remains unknown to me at this time. If someone reading this is aware, then leave a comment below or shoot me a message via the Contact page.
