DMRC Opens Tender for Twin Tunnels, Two Subterranean Stations Along Central Vista Route.

The Delhi Metro Rail Corporation (DMRC) recently invited bids for the design and construction of twin underground tunnels and two new stations under Phase V(A) of the Delhi Metro project along the Central Vista corridor.

According to DMRC, the project will include twin tunnels between Shivaji Stadium and Central Secretariat using Tunnel Boring Machines (TBMs), as well as a cut-and-cover tunnel stretch extending up to Kartavya Bhawan. The contract also covers the construction of two underground stations—Central Secretariat and Kartavya Bhawan—along with entry and exit structures, pedestrian subways, and related civil works.

The selected contractor will handle both design and execution, including structural works, tunneling, station construction, utility integration, and associated infrastructure. The project will require detailed geotechnical studies, continuous ground monitoring, and advanced technology to ensure safety and minimize impact on surrounding structures.

The tunnels will run close to existing operational metro corridors, necessitating careful coordination to maintain uninterrupted services. DMRC said real-time instrumentation systems will be deployed to control ground settlement and safeguard nearby buildings and utilities.

Located in a high-security administrative zone, the Central Vista corridor houses several key government buildings. The new metro infrastructure is expected to significantly improve connectivity in the area. Final timelines will be determined after the bidding process concludes.

The development comes a day after the Cabinet approved three new corridors under Delhi Metro’s Phase V(A) project at an estimated cost of Rs. 12,014 crore, adding over 16 km to the network. The approved corridors include RK Ashram Marg to Indraprastha (via Central Vista), Tughlakabad to Kalindi Kunj, and Aerocity to Indira Gandhi Domestic Terminal-1.

The RK Ashram Marg–Indraprastha corridor will provide direct metro access to Kartavya Bhawan and surrounding offices, benefiting nearly 60,000 office-goers and around 2 lakh visitors daily. The expansion is expected to reduce traffic congestion, curb pollution, and ease daily commutes for thousands of people.
