Tunnelling Asia 2022, organized by TAI, which took place in Mumbai during 27th and 28th June, saw a huge gathering of delegates/engineers from all around the world. The theme of the conference: ‘Underground Space: Need of the Day’ focused on the methodologies and technologies available for enabling fast-paced tunnel construction.
Lt. Gen Suresh Sharma, Senior VP, Tunnelling Association of India (TAI), while inaugurating the conference, emphasized on the growing importance of tunnelling in urban areas. “We can see the tunneling methodology shifting from DBM to NATM, while Micro-tunnelling is picking up because of the growing need for utilities and sewage. There is a lot of investments coming in, given the growing importance in hydro power projects, irrigations, railways, water supply, roadways, and sewage. TAI has analyzed 1726 tunnels spanning over 3600 km, till date, of which, 1200 have been completed, which means 2200 km of tunnels are yet to be constructed.”
He also informed the audience about the huge tunnel - a railroad project of the Border Roads Organization - being built below the Brahmaputra River.
