5 civil construction firms (2 in a consortium) have submitted bids for underground Package UG-06/RT-01 of Chennai Metro’s 44.6 km Line-5 after Chennai Metro Rail Ltd. (CMRL) opened technical bids today.
This roughly 5.8 km civil package of Chennai Metro’s Phase 2 project consists of twin tunnels and 5 underground stations between Kolathur and Nathamuni on the mostly elevated Line-5 which will connect Madhavaram and Sholinganallur through 45 stations.
This is a contract retender. In the original round, L&T was the only bidder in August 2021 and was naturally declared as the lowest bidder in November 2021. Their bid was substantially higher than CMRL’s estimate, which led to the cancelation of that tender and re-invitation of bids in December 2021.
In this round, CMRL has set the contract’s estimated value at Rs. 1580 crore and would like work to be completed within a 1395 day (3.8 year) deadline.
