The CompanyLarsen & Toubro Limited (L&T) is India’s leading

engineering and construction conglomerate. Its

reputation is based on a strong customer orientation and

the technological sophistication that characterises its

products and projects.

ECC - the Engineering Construction & Contracts

Division of L&T makes critical and vital contributions to

the core sectors of the industry. It includes infrastructure

development. ECC undertakes single-point responsibility

for execution of major projects involving comprehensive

engineering and construction services, meeting stringent

quality standards and delivery schedules.

Landmark Projects

For over six decades, ECC has been building Landmark projects

in India and abroad. The hallmark of ECC’s continuing success

is its ability to execute complex projects of large magnitude

with in the stipulated time and cost as per international

standards of quality and safety. Experienced project managers

and skilled engineering, procurement and construction

management teams play a vital role in successful project delivery.

Turnkey Capabilities

Innovative techniques accelerate the pace of construction and

ECC’s comprehensive construction capabilities overcome

challenges of engineering and logistics. Strategic alliances with

world leaders enable ECC to access the latest technical know-

how and execute technology-intensive, large-scale turnkey

projects.

Through the successful execution of a number of complex

projects, ECC has acquired world-class technical expertise and

leadership in many of its areas of operation. ECC has earned

the confidence and trust of innumerable customers, who have

entrusted it with major contracts in India and abroad.

Today, ECC is executing some of the largesthydroelectric power projects (such as the 2000 MWSubansiri Lower Hydroelectric Project) in India and itsneighbouring countries - Bhutan and Nepal. Some ofthem are being executed on EPC basis. Yet anothernotable feature is the ongoing construction of Asia’sfirst underground cavern at Vizag for storing 60,000tonnes of LPG.

Ever increasing population in metrosand major urban centres demandsconstruction of tunnels to complementmillions of kilometers of highway andrailway networks providing vital linksto the nation as a whole.

ECC has made a vital contribution tothe development of transportationinfrastructure, particularly in the areaof road and rail tunnels includingconstruction of underground metro railcorridors. It has the necessaryresources, latest know-how and ProjectManagement expertise coupled withquality and safety for construction ofall types of underground structures.State-of-the-art systems and cuttingedge technology like cut and cover, topdown, NATM, tunnel boring machines(TBM), earth pressure balancingmethod (EPBM) and other advancedmethods are extensively used today asper project requirements for meetingthe construction needs.

Capabilities cover construction of:• Railway Tunnels• Road Tunnels• Metro Tunnels• Large Underground Caverns for

storage of Liquefied Products• Underground Caverns for Power

House, Transformer Caverns etc.

POWER

• Fabrication and erection of gates, penstocks and other hydro-mechanical works and erection of electro-mechanicalequipment.

• Refurbishment of old hydro power plants.

• Preparation of pre-feasibility, feasibility and detailed projectreports for hydroelectric power plants

• Geo-technical investigation and reports for hydro projects.

• Access roads and other infrastructure

• Switchyards, electricals and transmission lines.

Harnessing energy from moving waterwas known to man many years back. Aperennial source of electrical energy,hydroelectric power, is non-polluting andenvironment friendly. It is also efficient andinexpensive.

ECC is poised to make a significantcontribution to the development ofhydroelectric power plants in India. Itundertakes turnkey construction, involvingengineering, procurement and constructionservices. Construction is also undertaken onBuild - Operate - Transfer (BOT) basis. L&Tis a pioneer in executing BOT projects andcurrently a number of infrastructure projectsare operated by L&T on BOT basis indifferent parts of the country.

The power of choice and promise of the future

India is a growing agricultural economy and there is an everincreasing demand for large-scale irrigation of agriculturallands. This has necessitated the development of larger, morecomprehensive irrigation schemes using structures such asdams, weirs, diversion structures and water distributioninfrastructure for irrigation projects. Lift irrigation schemesare also adopted for larger stretches.

ECC offers a wide range of service for the construction ofIrrigation structures, such as:

• Barrages

• Lined and unlined canals and aqueducts

• Lift irrigation Schemes including pipelines.

• Rehabilitation and modernisation of existing irrigationschemes

• Intake structures - open and closed channels
