With in-depth knowledge of marine technology, maritime structures such as greenfield ports, breakwaters, docks, container terminals, bulk berths, liquid jetties, shipyards, shiplift systems and shore protection have been engineered and built to spearhead waterway transportation.

In-house expertise in design, quarrying and state-of-the-art equipment ensure world-class quality and timely delivery.

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!

Special Bridges
L&T has bridged people and places in several countries across Asia with the finest bridges. Having pioneered the design and 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, prestressed concrete
  • Steel and concrete composite construction
