GLM-SAM Lowers Kanpur Metro’s TBM S93 at Bada Chauraha

Gulermak – Sam India Builtwell JV this Sunday began lowering parts of tunnel boring machine S93 (TBM Ganga) at Bada Chauraha Station for tunneling the first 3.619 km underground section of the 32.4 km Kanpur Metro Phase 1 project.

This new 6.52m diameter & 120m long Terratec Earth Pressure Balance (EPB) machine had passed factory acceptance tests in November 2021 and arrived in town in February 2022.

Per the tunneling plan, this machine on the up-line along with the refurbished TBM S92 on the down-line will be deployed on Package KNPCC-05 for a total of 4 drives each:

• Bada Chauraha to Nayaganj: 989.5m
• Permat Ramp’s cut & cover tunnel to Chunniganj: 414m
• Chunniganj to Naveen Market: 748m
• Naveen Market to Bada Chauraha: 516m

Gulermak – Sam India was awarded Package KNPCC-05’s contract by UPMRC in March 2021 with a combined value of Rs. 769.23 crore & USD 3.674 million. Besides tunneling, they will construct 4 station at Chunniganj, Naveen Market, Bada Chauraha and Nayaganj, each 215m long.

Global EPC contractor Gulermak has completed tunneling projects all over the world, including Lucknow Metro where tunneling with Tata Projects in a JV was completed ahead of schedule.

Just earlier this month, they recorded Pune Metro’s 8th and final TBM breakthrough for the Purple Line’s 6.52 km underground section, and in my interactions with employees they intend to finish Kanpur’s work in a similar fashion.
