Afcons Wins Mumbai-Ahmedabad Bullet Train’s C2 Tunnel Contract

June 8, 2023 Update: Afcons and NHSRCL have signed a Rs. Rs. 6397.27 crore contract for the civil construction of Package C2. LOA was issued in mid-May.

April 6, 2023 Original Post: After much drama in the construction industry’s circles, Afcons Infrastructure today emerged as the lowest bidder to construct 20.377 km underground Package C-2 of the 508.17 km Mumbai – Ahmedabad High Speed Rail (MAHSR Bullet Train).

Package C2 of the main-line will link chainage Km 0.773 (Bandra Kurla Complex Station) to Km 21.150 (Shilphata Ramp) and consist of roughly 3 km “undersea” twin tunnels below Thane Creek. The appointed contractor will be required to use at least 3 Mega TBMs with a diameter of roughly 14.5 meters.

National National High Speed Rail Corporation Ltd. (NHSRCL) had originally invited bids for this package in 2019, which received zero bids, and then again in November 2021 which was canceled in February 2022.

For the latest round, bids were invited in September 2022 with a 1888 day (5.17 years) deadline and an unknown estimate. Technical bids were opened in February to reveal 2 bidders – L&T and Afcons.

Technical bid evaluation was completed on Wednesday. When financial bids were opened today, it was revealed that Afcons offered a 9.11% discount which allowed them to narrowly clinch the contract. L&T offered none.

Financial Bid Values

Afcons InfrastructureRs. 7009.88 crore
Larsen & ToubroRs. 4577.61 crore + USD 245 million

IFB Number: Package No. MAHSR-C-2

Brief Scope: Construction of Tunnelling Works including Testing and Commissioning for Double Line High Speed Railway using (TBM) and (NATM) between Mumbai Underground Station at Bandra-Kurla Complex (MAHSR Km. 0.773) and Shilphata (MAHSR Km. 21.150)

Without NHSRCL’s estimate, I can’t provide an assessment of how Afcons’ bid is placed. We’ll have to wait and see how this plays out.

If the bid falls within NHSRCL’s estimate, then we should see Afcons starting preliminary construction work in Q3 2023 and actual tunneling work in 2025. They’ve historically tied up with Herrenknecht for metro projects and more recently with Terratec for the Delhi-Meerut RRTS, so I believe their 3 TBMs will definitely come from either of those suppliers.

With this development, 135.45 km Package C3 (Shilphata – Zaroli) in Maharashtra is the only civil package left in the bidding stage. The current bid submission deadline is April 11 with technical bids scheduled to be opened on the following day, so stay tuned!

    Finally….. I don’t think NHSRCL has much option even if the bids are higher then estimated. They can negotiate ofcourse but i doubt the center or even Japan for that matter will want to delay this anymore.

    The damage is already done , 6 years wasted in bidding only, what a shame.. NSHRCL had to give contract to someone that’s why no estimate, 3 years of sena gormint, nobody wanted to touch any project in maharashtra, now new regime has finally placed the construction vehicle in 5th gear…C3 package going to Jkumar or Lnt, China constructing 10000km of HSR in 5years, India very close to finally able to award tender in 6 years

      The problem was with Maharastra Govt who was not giving Land in Gujarat work has started in November 2020

  13. RISHABH SINGH says:

    What was all the drama you are talking about?? Couldn’t find any relevant news regarding it…

    • TMRG says:

      An entire 6 hours of confusion on who won. Multiple bid values were floating around, all declaring L&T as the winner. A guy working in Afcons’ management publicly conceded defeat. Bless his heart.

      You won’t find this in the news media. They work off of copy-pasting press releases.

  14. D K Kunar says:

    Congrats Afcons Team and Tech Director for securing the Metro package.

  15. Sajad Bazaz says:

    I must say only Afcons could do such kind of projects after L&T which has under sea tunneling like difficult tasks involved. Congratulations and Cheers.

  16. SBS says:

    Why will tunneling start so late in 2025?

    • TMRG says:

      2 reasons –
      1) TBM launch shafts have to be prepared
      2) TBMs have to be custom manufactured per geology and tunnel profile requirements (they aren’t available off the shelf), pass factory acceptance tests, get dismantled, get shipped, get re-assembled and pass local site acceptance tests.

  17. Sunil says:

    The state authorities should have included navi mumbai on the route and then via thane. It would have been a big boost to that city and for Maharashtra to include one more city in the route.

  18. Unnikrishnan TS says:

    Congratulations ! While I appreciate the healthy competition, I’m sure AFCONS with its long rich experience in tunneling will scale new heights in this execution !
