L&T wins Chennai Metro Line-5’s UG6 Tunneling Work

Larsen & Toubro in October-end emerged as the lowest bidder for constructing yet another package of Chennai Metro’s Phase 2 project after Chennai Metro Rail Ltd. (CMRL) opened financial bids for Package UG-06.

This roughly 5.8 km underground civil package consists of twin tunnels and 5 underground stations between Kolathur and Nathamuni of the mostly elevated 47 km Line-5 which will connect Madhavaram and Sholinganallur through 48 stations.

L&T was the only bidder for Package UG06 when technical bids were opened in August, so it was fairly obvious they’d be the lowest bidder when CMRL moved on to technical bid evaluation and onward to the financial bid opening stage.

L&T’s Bid: Rs. 2230.93 crore

CMRL invited tenders for UG06 in January 2021 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).

Tender: CMRL/CON/PHASE-II/CORR-5/CP06/UG06/2021

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

Like other Phase 2 packages, CMRL’s estimate for this package is also unknown, but I hear L&T’s bid was below their estimate.

With this development, here’s a status of all 5 civil packages on Line-5 (north to south). L&T has been awarded 1 package so far and is the lowest bidder for another 3 packages:

Package CP10-EV-03 – 10.2 km viaduct, 11 elevated stations and 1 underground station between CMBT and Venugopal NagarL&T is lowest bidder
Package UG6 – 5.8 km underground section with 5 stations from Kolathur and NathamuniL&T is lowest bidder (this post!)
Package C5-ECV-02 – 12.431 km elevated section from CMBT to Alwartiru Nagar and from Porur Junction to Puzhuthivakkam with 12 stationsL&T is lowest bidder
Lines 4 & 5: Package C4-ECV-01 – 7.955 km elevated section from Power House to Porur Junction with 9 stationsAwarded to Larsen & Toubro
Package C5-ECV-03 – 11.61 km elevated section with 11 stations from Puzhuthivakkam to SholinganallurHCC-KEC JV is lowest bidder

Overall this is L&T’s 8th win out of 19 civil packages. A list of all Phase 2 civil packages and their status can be viewed here.

    Hey tmrg, it’s been months and yet they haven’t awarded the contract for line 5’s cmbt to Venugopal Nagar section and l&t being the lowest bidder. Any issues where one firm can be contractor for only one package in a corridor?
