Geotechnical Investigations Begin for Delhi Metro’s Phase 4

Numerous geotechnical engineering firms have started soil investigations throughout Delhi for the upcoming Phase 4 project which just grew to 108.79 km long. The data captured through this activity will serve two purposes – (1) help determine a optimal line alignments, especially in the underground sections, and (2) later be included within the civil construction tender documents to help infrastructure companies make accurate financial bids & use appropriate machinery, methods & technology during construction.

DMRC invited bids for 3 packages of this service in December 2016 while it was awaiting the Delhi Government’s approval which finally came through in January 2017. The 3 contracts for it were awarded in early March:

• Geo-Technical-1: Detailed geotechnical investigation work for Rithala – Bawana Narela corridor and Janakpuri – Majlis Park (including) corridor.
Contractor: Unknown

• Geo-Technical-2: Detailed geotechnical investigation work for Majlis Park (excluding) – R K Ashram corridor, Majlis Park – Maujpur corridor and Inderlok – Indraprastha corridor.
Contractor: Unknown

• Geo-Technical-3: Detailed geotechnical investigation work for Tughlakabad – Aerocity corridor and Lajpat Nagar – Saket G Block corridor.
Contractor: Cengrs Geotechnica Pvt. Ltd.

TMRG follower Simarjeet Singh spotted men with a tripod in west Delhi’s Keshopur by which the Magenta Line’s 28.92 km Janakpuri (W) – RK Ashram extension will be built on the Outer Ring Road:

Phase 4’s Current Status

Apart from last week’s approval of the Red Line’s 4.86 km extension to Kundli, things haven’t significantly changed in the pre-construction stage since my previous update which included an updated official map & detailed table of the project.

    TMRG!!! Where is the extension of vaishali metro towards mohan nagar??? Why isnt this happening?

    • TMRG says:

      Hi, DPR is ready. Ghaziabad Development Authority followed by UP government’s cabinet need to approve it now.

  2. ANJAY ANAND says:

    what is the proposal of yamuna bank to kajoori via Gandhi nagar shastri park.. This rout need metro and pending due from first phase

    • TMRG says:

      It was initially planned to be built in Phase 4, but the DMRC and Delhi Govt no longer see a need for it. With the limited funds available, other routes have been given priority.

    I spotted geotech teams boring at multiple places near Devli Khanpur area on Tughalkabad Aerocity Line one week ago.

    • TMRG says:

      Good stuff!

      If you have any images, feel free to get in touch with me using the ‘contact’ form above and I’ll plug them into the post.

    When do you expect the tendering will be started for construction of phase IV

    • TMRG says:

      Hi, in Phase 3, DMRC started inviting bids for construction months before central government’s approval, but in Phase 4 there’s one big roadblock. It’s still not clear which external agency is going to provide a loan and how is the funding pie going to be split between them, state government and central government.

      So it could take a couple months (initially supported by state funds for elevated sections) or years to start.

    I saw one of these boards in Vasant Kunj today. Will try to take a pic sometime.

  7. Vishal says:

    Are they extending the line from Noida Sec 62 to Indirapuram ?

    Sometime back head that GDA has approved the budget and has asked DMRC to submit DPR ?

    • TMRG says:

      Yes, that’s one of the plans. In fact, I believe they want to extend it all the way to Mohan Nagar in Ghaziabad.
