The Company

ECC, the Engineering Construction & Contracts Divisionof Larsen & Toubro Limited, is Indias largest constructionorganization. It has leading-edge capabilities, whichcover every discipline of construction: civil, structural,

mechanical, electrical and instrumentation. Many of thecountrys prized landmarks its exquisite buildings, talleststructures, largest industrial projects, longest flyovers,highest viaducts, longest cross-country conveyors andpipelines have been built by ECC.

Steel - Building Material of Choice

Due to its inherent advantages structural steel is thematerial of choice for the construction of industrialprocess plants, building structures, transportationstructures and other technological facilities.

Steel is Our StrengthKeeping pace with the changing times and tuned toinnovation, L&T has designed and constructed some ofthe Outstanding Steel Structures in India and abroad. Ithas made use of steel to provide effective and productivesolutions tailored to meet its clients needs.

L&T has a high reputation for fabrication and supply ofhigh-end process plant equipment as well as fabricationand erection of all types of steel structures for various coresector industries. State-of-the-art fabrication facilities

coupled with extensive expertise in design, erection,

testing and commissioning of massive steel structures,enable L&T execute major projects on EPC basis. Thus, ithas over the years evolved as one of the largest users ofsteel for industrial and building construction.

The high strength of steel combined with its light weight,outstanding ductility and durability, aesthetic appearanceand recyclability, makes it the most preferred constructionmaterial. Today, steel is increasingly combined with wood,glass, concrete and other finishing materials to producevisually appealing, aesthetic and functional structures.

Engineering Designand Research Centre

The Engineering Design and Research Centre (EDRC)of ECC at Chennai, Bangalore, Kolkata, Mumbai and

Middle East offers fast and accurate solutions for designengineering and consultancy services for all types ofconstruction projects. It has extensive experience inanalyzing the static and dynamic loads of plant andmachinery including structural loads through finiteelement analysis. EDRC employs over 600 experienceddesign engineers/technical personnel who meet everyspecific need of the customer.

L&Ts team of specialist engineers with long experience inquality management and quality assurance meets everystringent standard and specification both national andinternational - including the increasing demands of its

customers.Meticulous planning and optimized deployment ofresources for fabrication and erection helps L&T executethe most complex and critical steel structures with highquality, speed and economy to the complete satisfactionof the client.

Steel Constructions

The number of all-steel construction projects built byECC for various customers is steadily increasing. Overthe past 20 years, ECC has consumed more than onelakh tonnes of steel for industrial structures as well as

related infrastructure facilities. ECCs fabrication shopsat Kancheepuram, Pondicherry and Pithampur havebeen meeting this growing need for fabricated steel fordomestic and international customers. L&Ts state-of-the-art modular fabrication facility at Hazira in Gujarat isone of the largest in the whole of South Asia.

In addition to bridge structures, industrial plants and longspan storage structures, steel structures have becomea major component of multiplexes. Airport terminalbuildings, hangars, sports stadiums and the new lookrailway station buildings are now using a combinationof artistically created and aesthetically pleasing steel

structures.

The new station buildings built by L&T at Chennai formetro rail transit system (MRTS) have adopted the barrelvault, aerofoil roofing systems as well as cable stay typeof roof.

For the 1.2 MTPA state-of-the-art Lafarge Surma CementPlant at Chhatak, Sunamganj in north east Bangladesh,L&T constructed a 17.5 km long cross country beltconveyor for transporting limestone and shale from

Construction Methods

The Construction Methods Planning Cell (CMPC)complements site activities with safe and economicalformwork, erection schemes, method statements andproject planning. Wherever required CMPC offers innovative

solutions and implements construction methods andpractices to meet the specialized construction needs. As apart of the critical site construction activity, CMPC studies,identifies and develops enabling structures to facilitate thesmooth construction of structures for various projects.

The Steel Advantage

Highest strength-to-weight ratio among buildingmaterials

100% recyclable and non-combustible

Inorganic - will not rot, warp, split, crack or creep

Consistent material quality produced with stringentquality in accordance with national or internationalstandards and specifications

Light weight when compared to other building materials

Facilitates fast track construction

Environmentally positioned Green

Less scrap and wastage

Safer structures on account of high strength andfireresistantce

Not vulnerable to termites or chemical pesticides

Less damage in earthquakes, hurricanes, hailstorms,snow loads; lighter structure with stronger connections

results in less seismic force.

The Future

L&T is actively engaged in the design and construction ofsteel structures. With its high potential and vast expertise,L&T is effectively meeting international benchmarks ofquality in all its projects. Every project built by ECC is alandmark in its own right. And all of them stand tall payingtribute to L&Ts engineering and construction capabilities.L&T is all set to build a strong India.
