Chennai Metro Rail Ltd. (CMRL) today opened technical bids for constructing roughly 42 kms of underground tunnels (Packages TU01 & TU02) of Chennai Metro’s new 45.81 km Line-3 (Madhavaram – SIPCOT) to reveal 4 firms / consortia had submitted a total of 8 bids on October 29.
These tunnels on the Line-3’s 26.7 km underground section in the 118.9 km Phase 2 project will be built as part of a 52.01 km prioritized sub-project which will first see the development of Line-3 between Madhavaram – Sholinganallur and Line-5 between Madhavaram – CMBT.
CMRL had invited tenders (bids) for both packages in January 2020 with estimates of approximately Rs 1800 crore and 2500 crore, and expects the assigned contractor to finish all civil works within 1460 (4 years). Prior to that, CEG – AECOM JV had been appointed as its detailed design consultant (DDC) in September 2018.
Bidders for Both Packages:
- Gulermak Agir Sanayi Insaat ve Taahhut A.S. (Gulermak)
- Larsen and Toubro Limited (L&T)
- Shanghai Tunnel Engineering Co (Singapore) Pte Ltd – Woh Hup Pte Ltd Joint Venture (STEC – WH JV)
- Tata Projects Ltd. (TPL)
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.
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.
