All bids have now been sent for technical bid evaluation which can take a couple months to complete. When that is done, the financial bids of the technically qualified bidders will be opened to reveal who’s the lowest bidder and most likely supplier.

Siemens in May emerged as the lowest bidder for the 26 km Line-4’s electrification contract.

Things on the tendering side – both civil & systems – are moving along nicely although with some hiccups along the way for its rolling stock. A list of all Chennai Metro Phase 2 civil & system packages and their status can be viewed here.
