Tunnelling challenges on Mumbai’s Metro Line 3 revealed
Tunnel boring machines (TBM) used to complete the tunnelling for Metro Line 3 in Mumbai were called on to undertake a hybrid method in order to deliver a platform tunnel in hard rock, as well as deliver some tunnelling firsts for India.
The second of two 6.65m diameter Robbins Crossover XRE TBMs made its third and final breakthrough on the project delivered by a joint venture of Larsen & Toubro and the Shanghai Tunnel Engineering Company (L&T – STEC) in spring this year. However, the engineering challenges, such as the hybrid TBM/New Austrian Tunnelling Method (NATM), high groundwater pressures and variable ground conditions, it was used to overcome have only just been outlined.
Sao Joao and the folklore of wells

Synopsis
Wells are linked to life and death, and appreciated in India where so many dry areas survive through wells, whose waters seem increasingly scarce.
Revellers decorated with a copel (headgear) jumped in the well by maintaining a safe distance during the traditional Sao Joao celebrations at Arpora in North Goa.
Sao Joao was subdued in Goa this year. Because of Covid everyone had to tone down the Feast of St. John the Baptist which Goa uniquely celebrates with people jumping into wells and other freshwater sources. People just made the flower crowns called kopels and did some local splashing.
