Larsen & Toubro’s 12.19 m dia Slurry TBM (Tunnel Boring Machine), named ‘Mavala’, has achieved a world record for monthly lengths by excavating 456.72 m at the prestigious Mumbai Coastal Road Project, Package 4. Deployed from Girgaon Chowpatty, the TBM, presently the largest deployed in the country, broke the previous global record of 455.4 m for monthly tunnelling done by a 13m single shield EPB (Earth Pressure Balance) TBM.

TBM Mavala was delivered during the height of the pandemic. Weighing approximately 2,500 tonnes, the TBM was then lowered into the launching shaft in a fully assembled form. Another innovative method they adopted was to ‘rotate’ the TBM inside the shaft to start the second tunnel construction which saved them several months to dis-assemble, lift, transport, re-assemble & lower the TBM at a new location.

The Mumbai Coastal Road Project (MCRP) Phase-1 is a 9.98 km section from Princess Street Flyover at Marine Lines to the Worli end of the Bandra-Worli Sea Link (BWSL) involving sea front development and is a first-of-its-kind in India. The project is divided into 3 Packages viz. Package-I – From Amarsons Garden till Baroda Palace, Package-II – From Baroda Palace connecting it to Bandra Worli Sea Link & Package-IV – From Princess Street Flyover at Marine Lines to Priyadarshini Park. L&T is executing Packages I & IV for MCGM involving the construction of a 3.82 km long section over reclaimed land from Priyadarshini Park to Baroda Palace and interchanges at Amarson Garden and Haji Ali. Package IV involves the construction of a 2 km long twin bored tunnel along with cut & cover, ramp, etc. to form a combined road length of 4.06 km. When completed, it would be the largest and deepest bored road tunnel in India.
