Heavy Civil
Infrastructure

L&T's construction expertise has been offered for the elevated and underground sections of Chennai Metro including ballastless track work and a massive depot. The Company has been engaged in creating robust portals of connectivity for mass rapid transit systems in most of India’s major cities - Delhi, Mumbai, Kolkata, Hyderabad, Bengaluru - and soon in Kochi and Lucknow.

The Heavy Civil Infrastructure business vertical of L&T Construction undertakes design, engineering and construction of projects in several segments that are crucial to the economy: metros, nuclear, hydel, ports, special bridges, tunnels and defence.

The business is a total infrastructure solutions provider, not just in India, but overseas as well. It has in-house design strengths and unique construction methodology cells which enable it to serve its customers by providing concept-to-commissioning solutions.

Metros:

The business designs and constructs above-ground corridors, piers and complex superstructures, including underground corridors using sophisticated tunneling techniques. It ventured into metro rail construction in 2001 with the prestigious Delhi Metro project. Since then, L&T has emerged as the leading builder of metro systems in the country, executing as many as 17 ongoing projects – including the Hyderabad Metro, which is the world’s largest in the PPP mode. In addition, L&T is involved in building major portions of the Riyadh and Doha Metros.
