Afcons & TATA Win Delhi Metro Phase 4’s Underground Work

Afcons Infrastructure and Tata Projects Ltd (TPL) today emerged as the lowest bidders for constructing 3 underground tunneling packages (DC05, DC07 & DC08) of the 65.1 km Delhi Metro Phase 4 project.

Delhi Metro Rail Corporation (DMRC) had invited bids for all 3 civil packages in May & June 2021 with a 42 month deadline financed by JICA through a Rs 8,390 crore ODA loan.

  • DC-05: Afcons is L1 (Magenta Line’s 7.46 km Derawal Nagar to RK Ashram section with 6 stations)
  • DC-07: Afcons is L1 (Silver Line’s 6.477 km Sangam Vihar to Tughlakabad section with 3 stations)
  • DC-08: Tata Projects is L1 (Silver Line’s 6.11 km Aerocity to Kishangarh section with 4 stations)

Package DC-05

This 7.46 km underground section connects a ramp north of Derawal Nagar with RK Ashram via 6 stations at Derawal Nagar, Ghanta Ghar, Pulbangash (interchange with Red Line), Sadar Bazar, Nabi Karim & Ramakrishna Ashram Marg (interchange with Blue Line).

This is the 4th (and final) civil package of the Magenta Line’s 28.92 km Janakpuri West – RK Ashram extension. Other packages are 12.375 km DC-01, 7.473 km DC-03R, 2.03 km underground DC-06 – all of which are under construction.

DMRC had previously estimated DC-05 to cost Rs. 2444.828 crore, but I’m not sure if that is still current. Technical bids were opened in September to reveal 4 bidders.

The assigned contractor will be required to use at least 4 tunnel boring machines (TBMs). DC-05’s design details such as crossover and ramp locations can be viewed here.

Package DC-07

This 6.981 km section on the eastern side of the 23.622 km 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.

DMRC 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.

Technical bids were opened in August to reveal 6 bidders. During technical evaluation, HCC – JMC JV and STEC were disqualified.

DMRC’s current estimates for all 3 packages are unknown, so I can’t provide an assessment on how Afcons and Tata’s bids are placed and what the next steps look like. Per an industry source they all seem “high”.

If these are within DMRC’s acceptable range, then we should see contracts getting awarded by year-end with basic ground work starting in Q1 2022 and actual construction work in Q2 2022.

With this development, financial bids for 3 out 4 JICA-funded underground packages of Phase 4 have been opened. See a list of all Phase 4 packages and their status here.

    DC-08 passes through very hard Aravali Rocks, I am not surprised that the bidding values are way over the estimate. Looks like DMRC will re-tender it. Rest look reasonable.

    Is there any application of NATM or Drill & Blast in DMRC new packages?

      Basic scope in the notices didn’t mention anything on NATM. Pretty sure some of the station boxes will require NATM work.
