Some of the most challenging projects that assist marine and waterway transportation have been designed and executed by L&T, aimed at minimizing costs and maximizing efficiency. With an in-depth knowledge of marine technology, L&T has created maritime structures such as docks container terminals, ports, harbours, jetties, berths, breakwater and shipyards. Other areas of specialization are quarrying, preparation of breakwater beds, shore protection works and associated marine construction works.
With its rich experience of tunneling in challenging altitudes and terrains like in the Himalayas, one of the world's toughest fold mountain ranges, L&T has built expertise in all types, sizes and shapes of tunneling with vast experience in construction of tunnels using various technologies such as the conventional Drill and Blast Method (DBM), the New Austrian Tunneling Method (NATM), Tunnel Boring Machines (TBM), Mechanical excavation or soft tunneling using road headers, etc.
L&T Construction is involved in over 100 km of tunneling for hydel projects and has deployed the tunnel boring machine for a tunnel length of about 9 kms in a hydropower project in Uttarakhand. Soft tunneling employing road headers is being carried out at the 2000 MW Subansiri Lower HEP in Arunachal Pradesh for a length of about 14kms, for the first time in India!
Having pioneered the construction of major bridges, L&T has extensive experience in executing a wide range of bridges of different span lengths using ingenious cutting-edge construction techniques such as:
- Incremental launching
- Segmental construction
- Cable stay
- Precast, pre-stressed concrete
- Steel, concrete composite construction
L&T's capabilities in bridge-building cover design and construction of many types of bridges all over the country.
