Larsen Toubro Limited

A majority of nuclear power plants and heavy water projects in India carry the L&T stamp of excellence.

Areas of expertise cover:

• Civil construction and erection services for nuclear containment structures (reactor buildings), control buildings, auxiliary buildings and other associated structures
• Design, consultancy including seismic qualification, procurement and construction services for pump houses, cooling towers, head end facilities
• Mechanical works and piping systems, associated detailed engineering, procurement and other related works
• Engineering, procurement and construction for electrical and instrumentation works
• Construction and commissioning of back end projects such as fuel reprocessing and storage buildings

L&T offers comprehensive engineering, procurement and construction services for executing water retaining and diversion structures, water conductor systems, power houses and substations, right up to evacuation of power through multi-circuit transmission lines. Keeping in line with the corporate commitment to sustainability, L&T has constructed pumped storage projects and run-of-the-river projects which do not negatively impact the environment.

Through a dedicated Hydel Business Unit, L&T offers a wide range of services for implementation of hydel power projects on EPC / BOT basis - including, but not limited to, construction of:

• Diversion weirs, barrages, concrete / earthen / rockfill dams including roller compacted concrete dams
• Underground tunnels of various geometry (both concrete lined and steel lined), pressure shafts, surge and de-silting chambers
• Large underground power houses and surface power houses
• Hydro-mechanical components such as gates, penstocks, etc., including erection of electro-mechanical equipment
• Preparation of pre-feasibility, feasibility and detailed project reports for hydroelectric power plants including geo-technical investigation reports
• Specialized underground structures such as storage cavern for LPG / crude oil
• Refurbishment of old hydropower plants

As an industry leader in augmenting capabilities for urban mass rail transit systems, L&T is involved in the construction of metro rail systems in almost all the major Indian cities including Hyderabad, which is one of the world's most prestigious and the biggest metro contracts on BOT basis. On the global front, L&T has made inroads in the Gulf region and is currently executing metro projects at Riyadh and Doha.

Structures developed by L&T for the metro, range from elevated rail corridors to underground metro rail corridors, station buildings along with alignment and expansive depots. L&T's EPC capability enhances the pace of operations. Technologies adopted include the conventional Drill and Blast Method (DBM), the New Austrian Tunneling Method (NATM), Tunnel Boring Machines (TBM), mechanical excavations and soft tunneling using road headers for underground alignment. Construction methods for erecting super structures include incremental launching and full span ???U' girders for the rapid completion of elevated corridors. The post modern precast yards help fast track projects well before the scheduled time.
