Larsen & Toubro is yet again the only bidder for constructing another package of Chennai Metro’s 47 km Line-5 after Chennai Metro Rail Ltd. (CMRL) opened technical bids for Package UG-06 last Saturday.
This roughly 5.8 km underground civil package consists of twin tunnels and 5 underground stations between Kolathur and Nathamuni of the mostly elevated Line-5 which will connect Madhavaram and Sholinganallur through 48 stations.
CMRL invited tenders for UG06 in January 2020 with a 1395 day (3.8 years) completion deadline. They require a minimum of 4 tunnel boring machines (TBMs) to be deployed for tunneling here, and out of those 2 must be sourced from Japanese manufacturers, per the conditions laid out by Japan International Cooperation Agency (JICA).
Brief Scope: Construction of underground stations at Kolathur, Srinivasa Nagar, Villivakam Sub-urban Station, Villivakam bus-terminus and Nathamuni with entry / exit, ventilation shafts, plumbing, earthmat, architectural finishes including signages etc. including twin bored tunnels from Kolathur retrieval shaft to Nathamuni launching shaft and ramps with U – section in corridor-5 of CMRL phase-II project
Whether CMRL is satisfied or not with receiving just 1 bid across 3 packages remains to be seen. If they aren’t, then this and others will head to a retender. If they are, then L&T’s technical bid will be evaluated for the next steps in the tendering process.
With this development, here’s a status of all 5 civil packages on Line-5 (north to south). L&T was awarded 1 package and is the only bidder for 3 packages:
