India's largest Tunnel Boaring Machine (TBM), 'Mavala' has been used to achieve this feat.
Moving closer towards the completion of Mumbai's coastal road project, BMC has successfully drilled over a kilometre-long tunnel using 'Mavala', India's largest Tunnel Boring Machine (TBM). Imported from China, this machine has a 12.9 meter-wide diameter which has hastened the progress of the entire tunnelling work, significantly.
As per reports, BMC began the tunnelling scheme of the coast road project in January 2021, with the aim to carve out 2.07km twin tunnels, each about 70 meter-wide, in 18 months. The work was, however, delayed due to the advent of the 'second wave' of the pandemic, and the consequent city-wide restrictions in March 2021.
Coastal Road Project stands at 40% completion
Despite losing three months of time on its work schedule due to pandemic limitations, the BMC has achieved a landmark achievement towards the development of the Mumbai Coastal Raod Project (MCRP). As per the project design, the slated coastal route will connect Nariman Point to the Bandra Worli Sea Link via two underground tunnels, stretching from Girguam Chowpatty to Malabar Hill in the town.
As of Saturday, the BMC has completed about 1-km tunnelling work of the twin tunnels pipelined on this 10.58-km route. Work has progressed from the south-bound arm of both the tunnels, read reports, and the remaining distance of over a kilometre will be achieved by January 2022. Presently, about 40% of the work on the coastal work has seen the light of the day.
MCRP delayed by 6 months due to COVID-19
If the BMC continues to work according to its initial timeline, the project will cover about 55% of development by the end of this year. Another 30%, cumulating to a total of 85% have been scheduled for completion in the next year, added reports.
However, the Chief Engineer of the parcel has told that the project is lagging behind by 6-months due to the unprecedented onset of COVID pandemic about 18 months ago. The deadline of the project is now marked in December 2023.
