In a first step as part of phase II of its network, Chennai Metro Rail Ltd (CMRL) has commenced soil tests in Madhavaram.
We have started with Madhavaram now and will conduct soil tests in other areas too,” an official said.
“These tests will tell us about various aspects, including the soil conditions underneath and the depth of the water table.
According to CMRL officials, the soil tests and geo-technical investigations at Madhavaram will reveal the geological conditions in the two corridors.
This is important because a majority of the 52 km stretch will be underground and to build that, we need to have precise information about the soil conditions.
