Larsen & Toubro is the only bidder for the construction of Chennai Metro Line-5’s 12.431 km elevated CMBT – Puzhuthivakkam section after Chennai Metro Rail Ltd. (CMRL) today opened technical bids for Package C5-ECV-02.

This elevated section’s viaduct and 12 sections are right in the middle of the 47 km Line-5 which will connect Madhavaram – Sholinganallur through 48 stations in the 118.9 km Chennai Metro Phase 2 project. It consists of 2 disjointed sections on either side of the double-decker Package C4-ECV-01 (Power House – Porur) which was awarded to Larsen & Toubro in May 2021.

The two sections and other infrastructure within this package include:

  1. CMBT to Alwartiru Nagar (approx. 3.2 km) with 3 stations at Grain Market, Sai Nagar Bus Stop and Elango Nagar Bus Stop

This section of Line-5 will be partly financed by the Asian Infrastructure Investment Bank (AIIB) through a $438.75 million (approx. Rs. 3266 crore) loan. The loan’s concept review was approved on April 7, 2020, and a formal appraisal decision is currently pending.

If CMRL and AIIB are not satisfied with 1 bid, then this package will head to a retender. If they are, then L&T’s bid will be sent for technical evaluation which can take a month or so to complete. If L&T qualifies, which they easily should, then their financial bid will be opened to see if their bid is within a certain range of the budgeted estimate for a contract to be awarded.
