7 Bidders for Delhi Metro Silver Line’s DC-08 Underground Work

November 232021 Update: Tata Projects (TPL) is lowest bidder (L1) for DC-08’s contract – see details.

August 10, 2021 Update: 7 construction firms have submitted bids to build the western-most underground section of the 23.622 km Silver Line after the Delhi Metro Rail Corporation (DMRC) today opened technical bids for Package DC-08.

This 6.116 km Aerocity – Kishangarh section of the Delhi Metro Phase 4 project comprises of 6.11 km twin tunnels, to be built by tunnel boring machines (TBMs), and 4 stations at Aerocity, Mahipalpur, Vasant Kunj and Kishangarh.

Its construction will be financed by the Japan International Cooperation Agency (JICA) with whom the Government of India reached an agreement and signed a Rs 8,390 crore ODA loan in March towards financing 44 civil & system packages, some of which have already been awarded.

DMRC invited tenders in April 2021 with a 42 month deadline and an unknown estimate. They’ve previously indicated this section to cost Rs. 1349.37 crore, but I’m not entirely sure if that’s still the current value.
