Robbins TBMs Commissioned for Mumbai Metro towards Hutatma Chowk

L&T-STEC JV today commissioned TBM Surya-1, a Robbins Crossover XRE tunnel boring machine (TBM), from the Churchgate Station towards Hutatma Chowk Station for building the 649m up-line tunnel of Mumbai Metro’s 33.5 km Aqua Line (Line-3).

This development comes just a few days after they commissioned TBM Surya-2, another Robbins Crossover machine, on the same section to build the 650m down-line tunnel. This is the third and penultimate drive for both machines which are expected to arrive at Hutatma Chowk in May 2020.

Here’s a status of package UGC-01 between Cuffe Parade and CST stations where 3 breakthroughs are pending. This table is best viewed on a desktop device –

At some point, I’d like to start compiling a monthly tunneling update like I did for Delhi & Bangalore with pending drives to give an idea of how other packages are performing.
