Bids Invited for Chennai Metro Line-5’s Underground Work

Chennai Metro Rail Limited (CMRL) on Thursday invited tenders (bids) for the construction of twin tunnels and 5 underground stations (Package UG-06) between Kolathur and Nathamuni of Chennai Metro’s new 47 km Line-5 which will connect Madhavaram and Sholinganallur through 48 stations.

This roughly 5.8 km underground civil package lies towards Line-5’s northern end and will be the only underground package of the entire line. This is so far the 11th tender notice for civil work on the 118.9 km Chennai Metro Phase 2 project and 3rd for Line-5.

Interesting to note that while tunneling and station work have been split up into 2 & 5 dedicated packages for the 45.813 km Line-3 (Madhavaram – SIPCOT 2), the scope of this line’s package includes both tunnel and station work.

Like Line-3’s 26.72 km underground section (Madhavaram – Taramani Link Road), this package will also be funded through an ODA loan by Japan International Cooperation Agency (JICA).

CMRL requires a minimum of 4 TBMs to be used for tunneling here and out of those 2 must be sourced from Japanese manufacturers, per the conditions laid out by JICA.

      A heavy ‘metro’ rail system is not being pursued anymore. Project will now be built as a light rail ‘metrolite’ system. Revised DPR is ready and currently pending AP govt’s approval.
