Tata Projects Limited and Lucknow Metro Rail Corporation (LMRC) has announced that they have completed Lucknow Secretariat to Hazratganj underground tunnel boring project.
LMRC and Tata Projects achieved the completion of the tunnel of 812-metres within 5 months (excluding one and a half months of waiting period to confirm breakthrough dates) of its commencement under the EPC (Engineering, Procurement, Construction) project. The 75-metre 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.
The state-of-the-art onboard computerised tunnel guidance system has been provided in the TBM to ensure that the tunnelling is 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.
Kumar Keshav, Managing Director – Lucknow Metro Rail Corporation said, “This unique achievement was only possible due to the hardwork 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 metres below ground level.”
“During the last 5 months this very complex project was executed in one the busiest of the 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,” said Vivek Singhal, Chief Operating Officer, Tata Projects Urban Infra.
