HCC Lowers Delhi Metro Phase 4’s First TBM S86 at Vikaspuri

Workers from HCC – VCCL JV today started lowering parts of tunnel boring machine S86 – the very first machine of Delhi’s new Phase 4 project – at the Vikaspuri Park Shaft to build a new 2.03 km underground extension of the Delhi Metro’s 38.235 km Magenta Line (Line-8) to the Vikaspuri Ramp near Keshopur.

This 6.52m diameter refurbished Terratec Earth Pressure Balance (EPB) TBM previously saw action in Lucknow, where it was deployed by Tata Projects Ltd – Gulermak JV to build tunnels for its 3.44 km underground section between Charbagh and Hazratganj ramps.

HCC – VCCL is responsible for building package DC-06 of the 61.679 km (and growing) Delhi Metro Phase 4 project which was awarded with a contract value of Rs 489 crore in January 2020 and deadline of 36 months.

Their scope of work involves building this section’s twin tunnels from the Vikaspuri Park Shaft (co-incidentally built by HCC in a JV with Samsung for Phase 3’s Package CC-34 north of Janakpuri West Station) to the Vikaspuri Ramp, with one underground station at Krishna Park Extension.

HCC-VCCL’s workers had started casting works for this section’s approximately 2100 tunnel ring segments at their Mundka yard back in July. Tunneling works are expected to start right before the year ends.

      JICA prouds itself in financing Delhi Metro. A Lot of Japanese and Korean Companies get business in the projects financed by JICA. Keep calm and trust Delhi Metro. They would certainly close the deal.

    After watching the site photo, it doesn’t look like a shaft. It mainly look like a metro station. TMRG, is DMRC have a plan to make this shaft into a metro station. I m saying that because the shaft is look same as a metro station. Please clarify this?

      It’s just a shaft – no plans to build a proper station here.

      They built it in Phase 3 (this was the launch site for CC-34’s TBMs), closed it and have now reopened it.
