3 Bidders for Mumbai Metro’s Dongri Depot on Red Line (CA-207)

Three civil engineering firms have submitted bids to construct Mumbai Metro Red Line‘s Dongri Depot after the Mumbai Metropolitan Region Development Authority (MMRDA) opened technical bids on Tuesday.

Dongri Depot & Workshop, under Package CA-207, is proposed to come up on 41.36 hectares of land in north-west Mumbai (view on Google Maps). This facility will be built to stable and maintain BEML trains for the entire Red Line (Line-9, Line-7 & Line-7A) connecting Dongri – Mira Bhayandar – Dahisar East – Gundavali – CSIA Terminal 2.

Besides an Operations Control Centre (OCC), Dongri Depot will consist of a 690m long test track with platforms, stabling shed (SBL) with 20 lines (with room for 18 future lines), workshop shed (WSL) area with 3 lines, an inspection shed (IBL) area with 4 lines, receiving substation (RSS) and two auxiliary substations (ASS).

MMRDA had invited bids for the depot’s construction in February 2024 with a Rs. 626.69 crore estimate and 52 months (4.3 year) construction deadline.

The bids have now been sent for technical evaluation which can take a couple months to complete. When that is done, the financial bids of the technically qualified bidders will be opened to reveal who’s the lowest bidder and most likely contractor.

As shared in the past – the contract’s duration at 52 months is unusually long since the site currently comprises of a hill which will have to be levelled. The package’s scope identifies the ‘land development’ component will include cutting, filling, preparatory works, tree transplantation and soil stabilization.

Access to the Dongri Depot will require a 4.9 km long extension of Line-9 on Uttan Road from Subhash Chandra Bose Ground Station. Here’s an alignment of the extension prepared by Line-9’s Detailed Design Consultant (DDC) Archom – Veritas – LKT Engineering JV in June 2023:

Back in September 2023, MMRDA formally submitted an application to obtain Coastal Regulation Zone (CRZ) clearance for this extension’s construction which will feature 2 new elevated stations at Murdha and Rai Goan. A tender notice for their construction is currently pending.

It goes without saying but once Dongri Depot is built, all Red Line BEML train-sets currently stabled & maintained at Line-2’s operational Charkop Depot and the under construction Mandale Depot will move to Dongri Depot.

    1) Any Update on Mumbai Metro L2B Half Height PSD tender? which was invited by DMRC. MS-04. I didn’t find it in your Yellow Line Tenders & Updates.
    Btw many Technical & Financial Bids opened of L2B Yellow line after Model Code of Conduct ended your page especially Yellow line one needs update.
    2) Local Media is saying atleast 3 months wait for Kanjurmarg Land.
    3) On 2nd July 5 bids will be opened unless they decide to extend the date.
    4) Mumbai Metro Line 12 work is in great speed.
    Here ☝️is the update on Casting Yard of Metro L12

      1) Missed writing about MS-04, but that was awarded to Zhuzhou CRRC Times Electric in July 2023. I’ve now updated Yellow Line’s page with all the information I have. Let me know if you have any further updates on specific contracts.

      2 & 4) Cool. As much as I love the rains, I can’t wait for them to end so things pick up

      3) Which ones? I only see Line-2B lifts & escalators (CA-162)

      • Aryan says:

        1) Thanks TMRG for the update on Line 2B PSD MS-04 Tender was looking for it since long 🙏.
        2) Now they are not revealing the Bidders Names & Winners Name. Looks like you have some Great Sources.

    Any update on MM3? RDSO rolling stock trials just finished, so I was expecting a July-end opening, but recent updates show a September opening

    • TMRG says:

      There’s pending architectural finishing work inside some of the stations. I’ve seen recent snaps and the signage is disappointingly small.

      Before CMRS, at least the following are needed:

      Speed Certificate from RDSO (likely received by MMRC)
      Schedule of Dimensions (SoD) certificate from RDSO (likely received by MMRC)
      Fire Department’s NOC for each station after mock-fire demo
      Independent Safety Assessment (ISA) certificate

      • Aryan says:

        As per some of the media Reports Mumbai Metro Line 3 Phase 1 from Aarey to BKC Deadline is now December 2024.

    There are several private lands in the middle of the car shed land. How will MMRDA give access to the owners of these lands and how will it achieve the hill levelling (cutting of the hill by 10mtrs) without touching these private lands?
