Piling Starts for all 7 TBM Launch Shafts of Mumbai Metro’s Line-3

Construction on Mumbai Metro’s 33.5 km underground Line-3 project has picked up this month with secant piling work for Tunnel Boring Machine (TBM) launch shafts now taking place at all 7 packages of the line.

Since the construction of underground stations is time consuming, these 7 launch shafts – one per package and generally 25m long x 25 m wide, are being constructed adjacent to one station of each package so that TBMs can be lowered into them for building the line’s twin tunnels.

The piling rig shown above has been keeping local residents awake at night.

Want to see what the shafts will end up looking like? Check out Lucknow Metro’s recently completed Bapu Bhawan Shaft where TBM S52 was lowered into last week. Coming back to Mumbai, the 7 shafts are expected to get ready, one after the other, in Q3 2017 after which tunneling works by TBMs (see a preliminary of 17 TBMs) will commence in Q4 2017.

    I can’t wait for the TBMs to start. Any idea on where they will drill first?

      Tunneling plan hasn’t been revealed, but you can easily guess some of the 1st destinations:

      UGC 1 – Cuffe Parade -> Vidhan Sabha (confirmed)
      UGC 2 – CST -> Kalbadevi (confirmed)
      UGC 3 – Science Museum -> Mahalaxmi (?)
      UGC 4 – Dharavi -> Shitladevi (?)
      UGC 5 – Vidyanagari -> Santa Cruz (?)
      UGC 6 – Sahar Road -> Terminal 2 (?)
      UGC 7 – Marol Naka -> MIDC (?)

    Information provided for UGC 03 is not correct. The first drive is expected from Science museum towards Acharya Are Chowk station, not Mahalaxmi.

    What is the exact location of stations on map? Any idea?

      MMRCL hasn’t revealed that, but I do know the locations for a handful. Which ones do you want to know about?

        MIDC, because just heard that it will come up at the old police quarters which have been demolished for the same, however wondering why the station will be so in from the central road. I also heard that they have started digging outside road 12, which makes more sense to have the station there as it is on the central road.
