Chennai Milestone
Chennai Milestone
METROS speed people to their destinations, cutting short the miles, saving time and money, while slashing carbon emissions at the same time. Metro construction deadlines, therefore, are sacrosanct.
Working against a stiff deadline, L&T GeoStructure achieved a major milestone in the Chennai Metro Phase-I Extension UG-009 project. Working hard and smart, the team completed and handed over the underground metro station and the cut-and-cover section at Tondiarpet well on schedule.
Both these facilities were inaugurated by Prime Minister Mr Narendra Modi and Tamil Nadu Chief Minister Mr Edappadi K Palaniswami on 14 February. 
This metro link is crucial: it connects North Chennai to the rest of the city and the underground section of Chennai Metro (Phase-I) to the elevated section via a ramp. At 200 metres the underground Metro station is spacious. Its four major entry structures, three vent shafts and ancillary building were constructed by L&T meeting high safety and quality standards. The cut-and-cover section has a 400-m roof slab, a base slab of 650-m and a 900-m side and mid-wall.
The L&T team, led by Mr Balamanikandan V and Mr Praveen K Shetty, achieved the commissioning within 20 months. This despite the constraints of the pandemic and challenges such as a difficult soil stratum, a congested area and narrow workspaces. The success of this project is yet another feather in L&T’s cap.
