Tunnelling

Below the surface. Above every standard.

In 2009, Cemindia set an Asian record - 37.5 metres of TBM tunnelling in a single day beneath the streets of Delhi. It was not an accident. It was the product of decades of accumulated expertise across every tunnelling method the ground demands i.e. TBM, M-TBM, NATM and box pushing. From Delhi Metro's first underground packages in the 1990s to Himalayan railway tunnels and urban sewer mains, Cemindia has tunnelled through soil, weathered rock and hard rock, beneath live railway lines, active city centres and open countryside without disrupting what lies above.

Featured Projects

Delhi Metro Phase III

Delhi Metro Phase III represented the largest underground metro construction programme in India at the time. Cemindia executed multiple underground civil packages across the Janakpuri–Botanic Garden and Pink Line corridors, deploying TBM and cut-and-cover methodology in some of Delhi's most congested zones. The works included station boxes, cross passages, and utility diversions across 12+ kilometres of alignment.

Mumbai Metro Line 3

Maharashtra

Kolkata Metro Extension

The East-West Metro in Kolkata required tunnelling beneath the Hooghly river — a first in India. Cemindia's package included underground station construction and tunnel lining works across the Howrah corridor. Ground conditions in central Kolkata posed extreme engineering challenges requiring precision grouting and real-time settlement monitoring throughout.

Bangalore Metro UG Section

Hyderabad Metro Phase II

Namma Metro's Phase 2 underground extension required tunnelling through Bengaluru's notoriously difficult mixed-face granite geology. Cemindia's scope covered underground station civil works, TBM launch shafts, and cross-passage construction. The project demanded innovative drill-and-blast sequencing in dense residential areas with vibration monitoring to protect adjacent structures.

All Projects

JAIPUR METRO PHASE II

2026Rajasthan

Jaipur Metro Phase II extends the network beyond the existing line into Jaipur's southern and eastern districts. Cemindia worked on viaduct and station packages with particular sensitivity to the heritage-listed zones along the alignment, requiring bespoke vibration management, ground monitoring and approval from the Archaeological Survey of India before every major operation.

Lucknow Metro Extension

2026Uttar Pradesh

The Lucknow Metro extension adds further coverage to a city experiencing rapid urbanisation. Cemindia's scope covers elevated civil and structural works, dealing with Lucknow's mixed alluvial geology, seasonal groundwater fluctuations, and busy road arteries beneath the proposed alignment.

Agra Metro Phase I

2026Uttar Pradesh

Agra Metro Phase I is being built in one of India's most culturally sensitive cities. Cemindia's elevated package required compliance with ASI regulations prohibiting heavy vibration within a 3 km radius of the Taj Mahal, demanding non-percussive foundation methods and noise-dampened construction techniques across the entire alignment length.

Bhubaneswar Metro

2026Odisha

Bhubaneswar Metro is part of the Smart City Mission's integrated transport vision for Odisha's capital. Cemindia's civil works cover elevated viaduct and station construction across a corridor that links the old city to the new development zones, requiring careful integration with the ongoing smart city utilities infrastructure beneath the roads.

Kochi Metro Extension

2026 Kerala

Kochi Metro's southern extension to Thrippunithura passes through some of the most densely built urban areas in Kerala. Cemindia constructed elevated viaduct spans and station shells, working around a network of canals, narrow road widths and high groundwater, characteristics unique to Kerala's coastal urban landscape that demanded innovative falsework approaches.

Contract CC-50 package for DMRC

2026Delhi

Contract CC-50 covered the underground civil works for a key station and running tunnel section within the Delhi Metro network. Cemindia executed diaphragm walls, station box excavation, and internal structural works in an exceptionally constrained urban corridor, managing ground settlement risks adjacent to existing metro infrastructure and heritage zones.
