Tata Projects sets tunneling Benchmark

 

Completes first part of tunneling for Lucknow Metro Rail project in record time, without any disruption to normal life of Lucknow citizens. ‘Earth Pressure Balancing Tunnel Boring Technology’ used as part of the 3.67 km Lucknow Metro Rail track project.

 

Early last month India’s EPC big league major Tata Projects set a record of sorts when it completed a 812 meters long tunnel within 5 months (excluding 1½ months of waiting period to confirm breakthrough dates) of its commencement, the tunnel is part of the Lucknow Metro Rail Track project, and is being executed in the EPC mode. The 75 meter long TBM (Tunnel Boring Machine) - Gomti saw the light at the end of tunnel and come out in the open (breakthrough) near Sahu Cinema at Hazratganj. An announcement to this effect was made jointly with the Lucknow Metro Rail Corporation (LMRC). The tunnel boring project was executed in a seamless, disruption free manner and in the fastest time period. The state-of-the-art onboard computerized tunnel guidance system ensured that the tunneling was done as per the designed alignment to the highest level of accuracy. Extensive instrumentation has been done throughout the underground stretch and continuous online and real time monitoring is done by a team of dedicated experts to ensure safety during TBM operation.

The TBM - ‘Gomti,’ successfully drilled this tunnel below the dense city center areas of Sachivalaya (the Secretariat area) and Hazratganj (Heritage Building area) without any disturbance to the buildings, public utilities, and traffic, on the land above. LMRC and Tata Projects have accomplished the difficult mission of not affecting the working of commercial establishments even for a day while tunneling beneath them. Tata Projects will now set up Gomti to construct another tunnel between the Sachivalaya and Hussainganj Metro Station as the next part of the construction plan.

 “This unique achievement was only possible due to the hard work and commitment of Lucknow Metro Project team. The tunneling in this stretch posed an enormous technical challenge as the route passes beneath highly congested areas and basements of commercial establishments to lay the tracks at the depth of 12 to 15 meters below ground level. With this ‘breakthrough,’ LMRC achieved one of the biggest milestones in form of completion of first TBM drive in the construction of underground metro in the state of Uttar Pradesh,” highlighted Kumar Keshav, MD, Lucknow Metro Rail Corporation.

Upon achieving this unique feat, Vinayak Deshpande, MD, Tata Projects beamed, “Due to many heritage structures, the stretch was highly challenging. With excellent guidance from LMRC team, state-of-the-art TBMs and dedicated, passionate project team, the daunting task was completed in a world class manner with outstanding quality and before time completion. We all at Tata projects feel very proud of this accomplishment and thank LMRC, and people of Lucknow for the cooperation extended."

 

 

 

 

PROJECT SCOPE

Tata Projects is executing the design and construction of the project overall, underground track of 3.67 km Charbagh Metro Station to KD Singh Babu Stadium Metro Station. Estimated to cost Rs.1,190 cr, Tata Projects will also construct three underground metro stations at Hussain Ganj, Sachivalaya and Hazratganj, which included Architectural Finishes, Electrical and Mechanical Systems (E&M), Tunnel Ventilation System (TVS) and Environment Control System (ECS) on the North-South Corridor of Lucknow MRTS, Phase I A Project. The company is implementing Top-Down Construction Methodology for station construction, wherein the permanent structure is built from top to bottom of the basement along with the excavation.

For speedy execution Tata Projects installed state-of-the-art ‘Earth Pressure Balancing TBM’ to ensure protection of Heritage Structures in Hazratganj Area. Unique Vibration sensors were installed in various buildings and on the ground to monitor vibrations within permissible limits. The company followed NATM construction methodology for ‘Cross Passage Construction’ to ensure safety. Air suction tubes and pumps were installed to ensure zero pollution and provide a healthier public transport option to the public.

“Today’s feat is a milestone achievement, during the last five months this very complex project was executed in one of the busiest areas and there was no disruption to the common man. We are sure that Lucknow Metro will prove to be a model metro rail project of the country and will be showcased as one of the best metro rail projects in the country,” adds Vivek Singhal,  Chief Operating Officer, Tata Projects Urban Infra.
