Mumbai Metro Line-3 – February 2018 Tunneling Update

With construction work picking up pace on Mumbai Metro’s new 33.5 km Line-3 (Cuffe Parade – Aarey Colony), here’s a consolidated update on the line’s tunneling progress highlighting key developments that took place over the past 2 months.

Going forward, I plan to publish a similar post at the beginning of every month which will hopefully answer a lot of questions and make the project’s progress clearer. Since March 1 is right around the corner, the next edition will be published on April 1 or sometime in its first week. In case you’re unaware of Mumbai’s neighborhoods or need a map to help visualize what goes where, then you can refer to the Mumbai Metro Info Page & Map.

MMRCL’s 5 contractors plan to deploy a total of 17 TBMs across the line’s 7 civil packages. In December 2017, they decided to personalize and name their TBMs after local rivers in Maharashtra – Surya, Vaitarna, Tansa, Krishna, Godavari, Tapi and Wainganga to “create a sense of belonging”. For instance, Package UGC-04’s 3 TBMs have been named Krishna-1, Krishna-2 and Krishna-3.

As of the morning of February 21 –

• 5 TBMs have been commissioned (T-59 ‘Vaitarna-2’ will be commissioned today at Azad Maidan)
• 2 TBMs have been lowered into their respective shafts (T-59 ‘Vaitarna-2’ and T-60 ‘Godavari-2’)
• 13 TBMs have passed factory acceptance tests (1 Terratec and 3 Robbins machines are pending)
• 11 TBMs have arrived in the city’s port from China & Singapore (2 refurbished TBMs which completed FAT in July 2017 are yet to arrive from Delhi)

On the systems side of things, technical bid evaluation is ongoing for the tunnel ventilation system (TVS), environmental control system (EVS), elevators and lifts, signalling and telecom systems. Bids for the rolling stock and automatic fare collection (AFC) system are planned to be opened in March 2018, while two contracts for the line’s traction & SCADA system will soon be awarded after JICA’s approval.

    This is one of the better post from you. I do appreciate the progress you guys have made in the quality of the post. The post is not only informative for general public but also to industry people like me.

    The format wherein you have compiled the progress so far is good. What i would recommend that you should add two more columns. One for the geology , i.e Basalt or Bercia and in second column date of TBM launch and if possible Commencement of final drive.

    This will help the industry engineers and estimators to understand the average productivity vis a vis TBM type and Geology.

    This is best update I have ever read.
    Keep going

  5. Anuj Wankhede says:

    Very nice and informative write-up.
    Could we also have some sort of timelines i.e how much is the estimated time for the tunnelling, station work etc (some would be done concurrently I presume) Also, is the work progressing as planned and delays in timelines.
    Once again, great job.

  19. Shreeharsha Phene says:

    Mr TMRG,

    Your latest post on Mumbai Metro 3 is really informative and deserves big Congratulations.

    While reading the post one realises that Robbins TBMs (3 in Nos) deployed at Section 1 – 2nos and Section 3 -1 No are still not passed the FAT.

    From the time taken by other TBMs from FAT to Final tunnelling drive ranges between 6 to 7 months.
    If not controlled right now this delay will surely put the entire project in to Delay mode.

    As it is the section 1 is riddled with legal cases foisted by Cuffe Parade Residents and Heritage building owners to add to it this avoidable delay by contractor L& T and Soma in getting TBMS on site is really causing concerns.

    Any updTe when realistically these TBMs will start their Final Tunnelling run ?

    Sir, I would request the MMRDA to give us better roads for metro station GHATKOPAR to versova which they have neglected the reasons best known to MMRDA, MCGM, CONTRACTORS, AND THE OFFICIALS We suffer a lot of traffic jam on road.

  21. shubh says:

    Do you know if MMRCL has made a Traffic Management Plan for this line? Where do you would it be available?
