Chennai: Work to build elevated structures of Metro Rail has started in 3 different locations as part of the 9km long phase-I extension project between Washermenpet & Wimco Nagar.

Foundation to build pile column & pile caps for the elevated viaduct on which rail tracks will be laid, is underway in a 3-kilometre stretch of the total 7km elevated corridor.

More Information:

  • Columns & pile caps are being built in locations close to Tondiarpet, Tollgate & Wimco Nagar stations, Metro officials said.
  • Officials said that the foundation work is likely to be complete in these locations by November.
  • An official said,”We started pile foundation work in 3 locations, as we wanted to start as early as possible. Separate tenders have been floated for pile foundation work in other elevated stretches and also for building the viaducts.”
  • In July 2016, construction work for 9.051 km phase-1 extension was launched.
  • The about Rs 3,770 crore (approx US$ 589.06 Million) project is expected to be completed by 2019.

About The Stretch

  • The stretch has a 2 kilometer underground line with 2 stations Theagaraya College & Korukkupet.
  • The rest is elevated with 6 stations covering a distance of around 7km incude — Tondiarpet, Tollgate, Thangal, Gowri Ashram, Thiruvottiyur & Wimco Nagar.

Further Information:

  • An official said,”We are expecting to complete tunneling work in the stretch by October this year.”
  • The soil tests conducted along the alignment in North Chennai showed they were favourable for construction of both underground & elevated corridors.
  • An official explained,”Soil conditions are crucial in deciding the depth of the foundation to be laid for elevated stretches. Since it is mostly clay and sand, excavation for both tunneling and building pile foundation for the elevated stretch can be done faster.”
  • Preliminary work like land acquisition process for the extension project began towards the end of 2015, much before it received the Centre’s approval, as officials wanted to begin construction immediately after getting clearances.
