DELHI (Metro Rail News): Delhi Metro Rail Corporation (DMRC) has officially opened the bidding process for two underground tunneling contracts, PC05 and PC06 of the Patna Metro’s Line-1 connecting Danapur Cantonment to Khemni Chak.

This spanning approximately 8 kilometers within the broader 30.91-kilometer Phase 1 of the Patna Metro project, will link Rukanpura Ramp and Mithapur Ramp through the construction of twin tunnels using tunnel boring machines (TBMs).

Each contract encompasses three underground stations and comes with a strict 42-month construction deadline, with funding secured through a loan from the Japan International Cooperation Agency (JICA). These contracts mark the final two out of the six civil construction packages, as listed, for the entire project to progress to the tendering stage.

Upon reviewing the tender documents, it has been observed that the initially planned station at Chanakya National Law University (CNLU) near Mithapur has been excluded from the current scope of work.

Details of the contracts are as follows:

Patna Junction Station will serve as an interchange between Lines 1 and 2. The ongoing construction of Line-2’s 14.05-kilometer tunnels connecting to Patna Junction is being executed by Larsen & Toubro as part of Package PC-03, awarded in December 2021.

Moreover, the Rukanpura Ramp of PC-06 will be integrated with the elevated section of PC-04, currently under construction by YFC Projects – Montecarlo JV. Simultaneously, Mithapur Ramp will connect to PC-04’s eastern section, also being constructed by YFC Projects – Montecarlo JV.

With these recent developments, the only major tender notice pending is for the project’s rolling stock (train) contract. The approval of JICA, coupled with the publication of PC-05 & PC-06’s notices, suggests that the tender notice for the trains is imminent.
