January 17, 2022 Update: DMRC has issued LOA to Afcons Infrastructure with a contract value of Rs. 1608.09 crore + Euro 68,00,000 (Approx. Rs. 1669,20,96,000.00) – see details.

November 23, 2021 Update: Afcons Infrastructure is lowest bidder (L1) for DC-07’s contract – see details.

August 18, 2021 Original Post: 6 construction firms / consortia have submitted bids to build Package DC07 of the 23.622 km Silver Line after the Delhi Metro Rail Corporation (DMRC) today opened technical bids.

This 6.981 km section on the eastern side of the Silver Line will connect Sangam Vihar Station’s east-end and Sarita Vihar Depot via 3 stations at Maa Anandmayee Marg, Tughlakabad Railway Colony, and Tughlakabad where it will form an interchange with the Violet Line’s station built in Phase 2.

Financed by JICA, DMRC invited tenders for this tunneling contract in May 2021 with a 42 month deadline and an unknown estimate. They had previously estimated it to cost Rs. 1365.51 crore, but that was up to only Tughlakabad Station. The package’s scope now includes tunnels all the way up to the existing Sarita Vihar Depot, which will be augmented to stable and maintain the Silver Line’s train-sets.

    Do you expect STEC to be disqualified in technical evaluation given the criticism govt had to face the last time they were awarded a contract.

    • TMRG says:

      Things have cooled down since Galwan, but you never know how this is going to play out. I wouldn’t be surprised if they’re disqualified on a random parameter.

      • SS says:

        Actually new Minstry of finance circular has given then leeway. The companies from country sharing borders with India have to show security clearance from appropriate authority before getting LoA. I am not sure if they have already acquired the permissions.
