Chennai Metro Rail (CMRL) has started its search for companies to conduct the soil test and design the alignment and the stations for Phase-II of the project. The phase spans a wide 108 km.
CMRL has reportedly floated separate tenders for both, soil tests and designing the alignment and stations for the underground and elevated sections of Corridor-3 and 5. As per reports, Corridor-3 will cover a 46.1-km stretch from Madhavaram to SIPCOT with 50 stations and Corridor-5 will cover 45.2 km from Madhavaram to Sholinganallur with 46 stations.
Phase-II, which is awaiting approval from the Centre, will cover 107.55 km with 104 stations estimated to cost about Rs 85,047 crore. Soil tests are crucial for deciding on the approach to be followed during construction of the line and the stations.
According to reports, the consultants will be conducting a detailed geotechnical investigation and complete the task in 10 months. CMRL has divided the corridors into small stretches and floated six tenders to conduct the test.
