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.

L&T’s Heavy Civil Infrastructure business vertical designs, engineers and constructs projects in crucial segments: 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. Its in-house design strengths and unique construction methodology cells enable it to provide concept-to-commissioning solutions.

Metros

L&T has expertise in end-to-end engineering and construction of elevated and underground metros, specialising in delivering metro projects on a turnkey basis using sophisticated tunnelling techniques. Having ventured into metro rail construction in 2001 with the prestigious Delhi Metro project, L&T has emerged as the leading builder of metro systems in India, executing 19 projects across 10 cities – including the Hyderabad Metro – the world’s largest in the PPP mode. L&T is executing major portions of the Riyadh and Doha Metros.

Areas of expertise

  • Elevated viaduct construction using segmental, U-trough and I-girder methods
  • Underground tunnel construction (NATM, cut-&-cover, TBM)
  • Underground station construction using top-down and bottom-up approaches
  • Elevated metro station and balanced cantilever constructions

Defence

L&T’s comprehensive range of engineering and construction services meets the specialised needs of the Defence sector. With massive investments planned by the Ministry of Defence for developing world-class systems and equipment, opportunities are aplenty in the areas of infrastructure facilities for defence bases, storage structures, underground facilities, niche technologies, security and surveillance and training facilities. L&T’s specialty is offering EPC (Engineering Procurement Construction) solutions with single-source responsibility for the execution of mega projects, from concept to commissioning.

Nuclear Power

L&T has played a crucial role in the nuclear sector by constructing most of the country’s nuclear power plants. It has developed expertise in both Pressurised Heavy Water (PHWR) and Light Water (LWR) reactor technologies, capturing the lion’s share of the market. L&T is attracting global companies in the field of LWR as partners to set up new plants in India. L&T should emerge as a front-runner in supporting India’s plan of supplying 25% of its electricity needs from nuclear power by 2050.

Areas of expertise:

  • Successfully executing EPC contracts in civil, mechanical, electrical and instrumentation segments of PHWR projects
  • Expanding our Engineering, Procurement and Construction capability by venturing into EPC contracts in LWR
  • Design, consultancy including seismic qualification, procurement and construction services for pump houses, cooling towers and other auxiliary facilities
  • Adoption of modular construction methodology for fast-tracking projects
  • Construction of Kudankulam Nuclear Power Project (LWR) – one of the largest projects in India’s nuclear industry

Special Bridges

L&T has built some of the finest bridges across challenging terrains, incorporating design features that are among the most complex of their kind. The Company has pioneered new technologies such as incremental launching, segmental construction, cable stayed, precast, prestressed concrete, steel and concrete composite construction. Apart from a pan-India project-scape, L&T has executed several projects in Malaysia, Dubai, Oman and Jordan.

L&T built India’s longest extradosed bridge across the Narmada river at Bharuch, Gujarat. L&T is building the world’s longest extradosed bridge at Patna, in a Joint Venture with Daewoo. It is executing three other iconic bridges across India and a major railway bridge project at Khulna, Bangladesh.

Hydroelectric Power Plants

L&T is a significant player in the development of hydroelectric power plants, and offers a comprehensive ‘water to wire’ range of services that facilitates the execution of hydroelectric power projects on an Engineer-Procure-Construct basis in tough mountainous terrains.

Areas of expertise:
