L&T Wins Chennai Metro Phase 2’s Tunneling Work

Besides Line-4’s elevated Package ECV-02, Larsen & Toubro today also emerged as the lowest bidder to construct roughly 42 kms of underground tunnels (Packages TU01 & TU02) using tunnel boring machines (TBMs) of Chennai Metro’s new 45.81 km Line-3 (Madhavaram – SIPCOT).

Both these packages on Line-3’s 26.7 km underground section of the 118.9 km Phase 2 project also consist of partial diaphragm & entry/exit structural work at 8 stations. The rest of the station work will be carried out through 5 dedicated station packages for which bidding is currently underway.

CMRL had invited tenders (bids) for both tunnel packages in January 2020 and expects the assigned contractor(s) to finish all civil works within 1460 (4 years). Technical bids were opened in October 2020 to reveal 4 bidders for each package.

Package TU-01

CMRL’s Estimate: Approx Rs. 1800 crore

Financial Bid Values:

FirmBid
Larsen and Toubro Limited (L&T)Rs. 1998.00 crore
Tata Projects Ltd. (TPL)Rs. 1999.00 crore
Gulermak Agir Sanayi Insaat ve Taahhut A.S. (Gulermak)Rs. 2270.07 crore
Shanghai Tunnel Engineering Co (Singapore) Pte Ltd – Woh Hup Pte Ltd Joint Venture (STEC – WH JV)Disqualified in Technical Bid Evaluation

Scope of TU01: Construction of approximately 9 km twin bored tunnels (total = 18 km) from the TBM Retrieval Shaft near Venugopal Nagar (of Line-5) to Kellys Station, and the construction of diaphragm walls, entry/exit structures of Madhavaram Milk Colony Station, Murari Hospital Station, Ayanavaram Station and Purasaiwakkam High Road Station, including launching and retrieval shafts at the above stations.

Package TU-02

CMRL’s Estimate: Approx Rs. 2550 crore

Financial Bid Values:

FirmBid
Larsen and Toubro Limited (L&T)Rs. 2385.00 crore
Tata Projects Ltd. (TPL)Rs. 2542.00 crore
Gulermak Agir Sanayi Insaat ve Taahhut A.S. (Gulermak)Rs. 2682.81 crore
Shanghai Tunnel Engineering Co (Singapore) Pte Ltd – Woh Hup Pte Ltd Joint Venture (STEC – WH JV)Disqualified in Technical Bid Evaluation

Scope of TU02: Construction of approximately 12 km twin bored tunnels (total = 24 km) from Kellys Station to Taramani Road Junction and the construction of diaphragm walls, entry/exit structures of Chetpet station, Royapettah Government Hospital Station, Thiruvanmiyu Station, and part diaphragm wall of Greenways Road Station, including launching and retrieval shafts at the above stations.

Here’s CMRL’s official map for Phase 2 with my edits emphasizing the start/end points of each package:

Line-3’s underground section: Venugopal Nagar – Kellys – Taramani Road Junction | Map via Chennai Metro Rail Ltd. includes my edits

In Package TU-01, L&T beat TPL by just Rs. 1 crore! L&T’s bid was Rs. 198 crore (11%) higher than CMRL’s estimate – so after negotiations – this should be awarded to them.

In Package TU-02, L&T’s bid was approx. Rs. 165 crore (6.47%) less than CMRL’s estimate, so there should be no issues during financial bid evaluation.

NOTE: This is unconfirmed right now, but CMRL may have placed restrictions on contractors winning more than 1 contract for Line-3’s tunnels to reduce risk, just like it was done in Ahmedabad Metro’s Phase 1. If that’s the case, then L&T and TPL will be awarded one tunnel package each.

UPDATE: It’s confirmed that one contractor can win only one package – see snippet from tender document below. For CMRL to achieve the least cost – following negotiations, package TU-01 will likely be awarded to TPL and package TU-02 to L&T.

Here’s a status of Line-3’s civil packages where bidding has started. Tender notices are still pending for the line’s elevated section between Taramani Road Junction and SIPCOT. That portion will be partly financed by the Asian Development Bank (ADB) through a $780 million (approx. Rs. 5890 crore) loan.

Line-3: Package TU01 – 9 km tunnels from Venugopal Nagar Shaft to Kelly’s Station and partial works at 4 stationsL&T is lowest bidder but TPL likely to be awarded contract (this post)

    Just to inform as per bid condition one bidder can get one package. So L&T and TPL will be awarded one pkg with criteria of least cost to CMRL. Even EMD for these two packages was combined.

    Still these packages are not awarded despite bids are well under CMRL estimates.
    Any timeline on when it will be awarded or the project work will actually start?
