4 Bidders for Kolkata Metro Line-6’s Airport Extension

Rail Vikas Nigam Ltd. (RVNL) today opened technical bids from construction companies to reveal that four firms had submitted tenders (bids) to build Kolkata Metro Line-6’s Package ANVS – a 3.519 km mostly elevated extension from Sub CBD-2 Station to Kolkata Airport (Biman Bandar).

This section of the 32 km Line-6 (Kavi Subhash New Garia – Netaji Subhash Chandra Bose International Airport) was originally envisioned to be underground, but large-scale land acquisition for its ramp and station at Teghoria (named Rabindra Tirtha) forced RVNL to convert a large potion of it – barring an approximate 950m airport stretch – into an elevated line.

RVNL invited bids for this package in June with an estimated value of Rs. 526.62 crore and expects the assigned contractor to complete all work within 36 months.


  • Afcons Infrastructure
  • ITD Cementation India
  • Gulermak
  • STS – KEC JV

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

Contract / IFB No: RVNL/KOL/New Garia-Airport/Metro/ANVS
