FocusWith thousands of people migrating to Mumbai

every month, the city’s infrastructure is hardly able

to cater to the burgeoning population, making the

lives of people in the already congested city very

difficult. With a view of provide a feeder system of

mass public transport, the Mumbai Metropolitan

Region Development Authority is building India’s

first monorail.

The Mumbai Monorail is a pioneer project in

more ways than one with innovative advances in

engineering, construction and management, not

just by Indian standards, but at an International level

as well. Once completed, the Mumbai monorail is

also slated to be the world’s second longest system

next only to the 23.8 km long Osaka monorail in

Japan. L&T has been making this infrastructure

dream of Mumbaikars come true and has also

conducted trails runs recently.

This issue covers L&T’s own temple of learning - the

Management Development Centre at Lonavla. With

more facilities added, the training centre has now

become one of the best campuses even surpassing

some of the best management institutes of the

country. Adding the list of first’s, L&T has created

a benchmark by commissioning India’s first ever

substation for evacuating power at two voltage

levels of 765 kV and 400 kV in the state sector

for Uttar Pradesh Power Transmission Corporation

Limited at Unnao.

Hindalco envisaged the setting up of aluminium

smelter cum power project at Mahan near Singrauli

in Madhya Pradesh. The Mahan Aluminium Project

includes a 359-ktpa Aluminium smelter and a 900-

MW captive thermal power plant. L&T is doing the

smleter project and also the coal handling project

for the captive power plant. The kaleidoscope

section, as usual brings to you a plethora of

corporate events, launches and happenings.

Wish you a happy reading!

Mumbai Monorail India’s first monorail corridor


The Mumbai Monorail project, currently under construction for the city of Mumbai, India

is a pioneer project in more ways than one with innovative advances in engineering, construction and management, not just by Indian standards, but at an International level as well. Once completed, the Mumbai monorail is also slated to be the world’s second longest system next only to the 23.8 km long Osaka monorail in Japan.

Although Mumbai monorail is the first large-scale monorail project in India, monorail technology has been used elsewhere in the world for over a century. However some of the structural design concepts and construction methodology adopted and implemented in Mumbai monorail can be considered the first in Indian construction history.

India’s first Monorail corridor, the Mumbai Monorail is the latest ‘dream project’ that could well make common man’s life better and easier. Construction of this prestigious project began in January 2009.

Scope of work

The work under this package consists of design and construction of Monorail system from Gadge Maharaj Chowk (Jacob circle) to Wadala (Approximately 10.64 km) and Wadala to Chembur via Mahul (approximately 8.9 km). The various scope of works involved in the project can be categorized into 4 distinct phases:

1. Phase # 1 – 8.9 km of viaduct + 6 Side Platform stations + 1 Central platform station

2. Phase # 2 – 10.64 km of viaduct

+ 8 side platform stations + 2 platform stations

3. Construction of depot building – 100 m X 100 m

4. Construction of depot guideway

Successful Monorail Trial Accomplished


1. India’s first commercial monorail is between Jacob circle and Chembur station via Wadala. Wadala also serves as the maintenance depot for the system.

2. The first section of the Mumbai Monorail project between Jacob Circle and Wadala will be 10.6 km long. Passengers will be able to cover the distance in 25 minutes. This route of the monorail will have 10 stations.

3. Second section of the Mumbai Monorail between Wadala and Chembur will be 8.9 km. Passengers will be able to cover the distance in 19 minutes. The route will have 7 stations. In all, the distance of 19.54 km from Jacob Circle to Chembur will be covered in 44 minutes.

4. The monorail train will run at a speed of 32 km per hour and will be completely air- conditioned.

5. There will be a total of 17 monorail stations, each at a height of 11 metres above the ground or road level.

6. Initially, a monorail will be available every 4.5 minutes. The waiting period proposed to be subsequently reduced to 3 minutes later.

7. Capacity per carriage or compartment of the monorail is 150 persons (30% seating and 70% standing with occupancy as 6 persons per sq. m).

8. Each monorail with 4 coaches will have a capacity to accommodate 600 passengers. Subsequently 2 cars can be added (the design of structures are based on the higher capacity)

9. Each monorail train will have the capacity to carry a passenger load of 8 - 10 buses.

10. The 19.54 km Mumbai monorail project is expected to carry nearly three lakh commuters who are currently taking buses, trains, taxis, auto rickshaws and private vehicles.

11. Mumbai Monorail should reduce 80,000 bus trips, 28,000 taxi and auto trips on a daily basis. Hopefully, 25,000 cars are expected to go off the city’s congested roads.

providers will prefer to undertake the design when such integrated systems have to be developed. In the case of Monorail Project – PJSI – Malaysia - is the structural designer. The station building design has been jointly done by L&T – Ramboll for only the concourse level and Geodesic – Bangalore for superstructure and architectural works. M/s Louis Berger, the Project Management Consultant (PMC) for this project was nominated by MMRDA.

StructureThe monorail guideway structure is unique in many ways since the structure also forms the running surface for the vehicle, unlike other rail or highway structures, which have additional surfacing, or track laid over the top. This fundamental constraint on the design criteria means that the beams have to be formed to suit the final alignment geometry, including both vertical and horizontal curves, gradients, transition curves and super elevation.

The substructure consists of 1000mm diameter bored cast in place piles with cast in-situ Pile caps,

Piers and Pier Caps. The design of the monorail structure is based on individually precast post tensioned beams that are erected and stitched together with in-situ concrete joints and continuity post-tensioning to form continuous frames of beams consisting of between three and five spans. Given that the alignment of the beams is so variable with multiple span combinations, each frame is unique.

Generally, spans are around 25m in length, however, due to various constraints such as road junctions, buried charted and uncharted utilities and drainage, as well as other structures such as stations and switches the spans vary anywhere between 16m to 28m.

Construction methodology

Shuttering scheme for casting yguideway beams was an innovative design

Usage of turnbuckles mounted yon the walls to set the correct curvature, radius and fit in +/- 2mm tolerance was indeed a technology by itself

Specialized schemes were ydevised to ensure smooth transportation of guideway beams. A separate floater assembly was designed to ensure that the bolster can carry the guideway beam of different curvature & different radii

Erection at critical locations ywhere road width is a constraint is devised based on the actual conditions at the site

The scheme which was yenvisaged is erection with the 200 t cranes (either crawler or Hydraulic). This primary scheme will be revisited and relooked at for critical locations

Construction logistics and management

A significant proportion of the construction utilized prefabricated or precast concrete construction, which

resulted in many of the activities getting centred on specialized casting, transportation and heavy lifting. The beams are precast in a purpose built factory near Wadala from where they are transported to the lifting location using multi-axle transport trailers. The lifting is typically done during nights using two telescopic mobile cranes and then placed by a sophisticated temporary works systems which will stabilize the beams and allow them to be adjusted later to the their final position prior to continuity works.

A typical frame comprises of four precast beams. Each element needs to be erected in sequence with the whole structure supported on a complex system of temporary supports and hydraulic jacks, whilst in-situ concrete joints and post tensioning are completed. Since the

majority of the erection operations could only be undertaken with partial road closures, the lift planning formed an integral part of the traffic management planning. The working window allowed for road closure and subsequent erection operations began during midnight and finished at 5.30 a.m.

Precast Factory

The superstructure of elevated structure is of precast guideway beam. Each guideway beam measures a minimum 16m to maximum 26m in length. Weight of each guideway beam is approximately 85 t.

The casting yard consists of:

Rebar bay: Soffit adjustment on trolley, rebar tying, insert fixing and shifting of trolley from rebar bay to casting bay

Rebar fixing at precast yard


Casting bay: Activities such as alignment of side shutters, concreting, de-shuttering of sides and shifting of trolley from casting bay to curing bay are carried out in this bay

Curing / stressing bay: Dimensional check, curing, stressing, shifting of beam to stacking yard and shifting of trolley to rebar bay. The rebar bay and casting bay is located in a covered shed to carry out beam production irrespective of climatic conditions. Mono strand jack is used for trolley movement from rebar bay to casting bay and further to the curing bay. RCC walls in casting bay help not only in supporting of side shutters but also ensure that with minor adjustment of turnbuckles, side shutters can be aligned to the required accuracy.

This resulted in elimination of side shutter handling and in achieving higher productivity or improved cycle time.

Lifting of curved and straight guideway beam

Challenge was to develop a universal lifting system for curved and straight

guideway beams of 26m length using two point lifting system. As the CG position of the beam varies due to curvature and length of the beam, the lifting point in the lifting frame needs to be adjusted to match the CG plane of the curved beam. An universal lifting frame with movable hook was conceptualised and engineered, eliminating the fabrication of numerous lifting frame for different beams.

A detailed calculation and engineering drawing was prepared for every curved beam indicating the position of lifting frame on the guideway beam and the setting position of movable hook in the frame for picking up the curved beam.

Transportation of curved guideway beam

With precast beams typically weighing 85t and upto 26 m in length, multi-axle hydraulic platform transport trailers were used. Sophisticated hydraulic suspension allows the trailer to raise and lower the trailer body by +/- 300mm which enables the transporter to negotiate difficult terrain. The linked hydraulic system even ensures load distribution to all wheels and the full control of the load stability. The trailer system is modular by nature and all axles can steer which permits the transporter to manoeuvre tight road junctions or a constrained site access.

As the CG position of the beam varies due to curvature and length of the beam, the position of the

guideway beam on the trailer needs to be adjusted to match the CG plane of the curved beam. A detailed calculation and engineering drawing was prepared for every curved beam indicating the position of guideway beam on the trailer for transportation. Guideway beams also needed to be anchored to the trailer while negotiating sharp curves to prevent it from toppling. This was achieved by clamping the guideway beams to the bolster with stressed macalloy bars.

Erection of guideway beams

Heavy lifting operations played a significant role in shaping the success of the monorail project. It was imperative to select the right type and capacity of crane for each and every lift. Prior to

the planned date of erection, a detailed survey was undertaken to check all site details and constraints such as road width, footpath dimension, trees, utilities etc., so that detailed planning could be done in advance.

Many of the locations were extremely congested and hence the positioning of the transport trailer and crane were studied before implementation. Two numbers of 200 t capacity hydraulic cranes or crawler cranes or combination of 1 hydraulic crane &

Curved guideway beam erection


1 crawler crane positioned on either ends of the span picked up the beams from the trailers and erected it over the pier cap. The guideway beam is then temporarily anchored on to the pier cap until the stitch or gaps between the beams are concreted.

Challenges faced

Monorail structures are monolithic in nature, the core of the Monorail project lies in the accurate casting of guideway and erecting the same as per the alignment. These beams which are being cast in a dedicated precast yard were done with utmost precision and tolerance limits as stringent as +/- 2mm. The curvature of the beams varied from 47 m radius to infinity or straight beams. The shuttering scheme was conceived, designed and established entirely by joint coordination with the site team and IET. The team achieved this by using a bottom shutter which

could be adjusted to the various super elevation or curvatures and side shutters which can be bent to various curvatures.

As the Right of Way (ROW) required for this type of transportation system is very less, this project

bypasses through narrow lanes and congested areas of the Mumbai metropolis. The added feature of the guideway beams which can negotiate horizontal, vertical, circular curves makes this project more challenging for transportation and construction activities.

Erection at creek-a feat during monsoon

Cross Over switch at 2A Series


The clearance of ROW was done in coordination with the customer. The process of applying for nodal bodies’ clearance and obtaining clearances from traffic department and more importantly creating awareness among the local public about the project was itself was a great task.

Despite utmost planning, the presence of charted and unchartered underground utilities and overhead cables posed a major challenge during execution.

Carrying out piling operations was crucial to ensure that there is no damage to any underground utilities.

The construction of pile caps which embeds major utilities was was under continuous supervision from nodal agencies.

Transportation of the guideway beams and Erection of the same

in certain congested localities was indeed a creditable effort. Most of the Operations right from marching of girder from the yard and positioning them on the pier cap very near to required geometry within a time frame of 5 hrs was done meticulously planning ensuring every aspect falls in the correct place for each beam is indeed a commendable effort. Specialized axles were designed and a lot of trails were done before the actual transportation.

Construction of station buildings measuring 80 m in length and 18 m in width at highly congested areas with a clearance of hardly 10m from the adjacent houses, for managing heat Environment & addressing all the Concerns on daily basis is actually a Greater challenge. Tailor made shuttering system that could be arranged within the barricaded

width of 8 m was extensively used to achieve results.

Logistics of manpower for the project was a perennial challenge. In a crowded city like Mumbai, the workmen colony had to be located 20 km away and the daily logistics was a major challenge. L&T established about 15 labour colonies spread across 20 km radius. The retention of labour during the period of heavy monsoon was a difficult task.

Interface with all departments such as signalling, communication and rolling stock right from the initial piling operations was a crucial but challenging task for the smooth progress of the project.

L&T’s Temple of LearningMDC Lonavla


Set amidst the idyllic locales of Lonavla, Larsen & Toubro’s Management Development

Centre (MDC) is a state-of-the-art, learning center that is spread across a sprawling 21 acre campus. Approachable both by road and rail from its nearest cites, Loanvla is about 90 km from Mumbai and 60 km from the city of Pune.

Serene Lonavla

Lonavla is one of the most popular weekend getaways for Mumbaikars who wish to unwind from their week long hectic city activities. A small hill-top town with lush green vegetation, tranquil rivers and a cool climate, Lonavla, offers complete peace of mind to visitors. This is also the reason why many corporates choose this location as an ideal place to set their learning and development centers.

MDC’s location was selected considering the isolated and hilly atmosphere, and the green environment which nurtures learning skills. Every morning, participants at MDC wake up to the chirping of birds and can watch the soft sunlight lifting off a blanket of fog to usher in another bright new day.

The design

The architectural team working on MDC was keen to blend the structures seamlessly into the greenery around the campus. The natural elements of waterfalls, rivulets, and flora were emphasized with fountains, landscaping and building masses. The architecture was such that it gives a feeling of space and enhances greenery at all locations of the campus.

Learning centre

The learning centre complex is inspired by the definition of Sir Churchill’s words on contemporary architecture, “We shape our buildings, thereafter they shape us”. The learning centre is built to inspire, enthuse and promote higher values and to enhance the skills in an individual.

The entire complex has been created without altering or damaging the existing topography, retaining the natural elements and ensuring minimum damage to the ecology of the place.

The articulation of space in this centre is a well thought out response both in terms of aesthetics and natural geography, built encompassing the values of yesteryears incorporating the modernity of tomorrow.

A fully stacked library


The design of the complex makes maximum use of utility space, thoughtfully allocating room for requirements without compromising on aesthetic values. In order to encourage an eco-friendly atmosphere, cars are parked away from the learning centre complex. The complex has been built prominently by locating it at a higher altitude as this structure is considered the most important building at the campus of MDC.

Dinning block

Strategically located in close proximity to Learning Centre Complex and the residential quarters, the dinning block has been designed as a single level structure oriented to have a serene view of both the central open area and the pond. It is also oriented for maximum exposure to sunlight and breeze.

The halls are placed on either side of central entrance lobby with a modern kitchen placed on its rear end giving no interference to visitors. Separate access has been planned from dining hall to central open area

for any informal gathering and outdoor catering.

A GLIMPSE OF THE PAINTINGS

A GLIMPSE OF THE PAINTINGS

L&T’s Management Development Centre,

established in 1997, has been engaged in

sharpening the minds and focusing the thoughts

of many young technocrats making them great

entrepreneurs and leaders of the future. Every

being on this planet seeks to achieve happiness,

is constantly engaged in the search of knowledge

and is in deep pursuit of excellence.

The foyers and galleries of MDC reflect this very

‘Searching Mind’, through the powerful and

impressive paintings and works of art by the noted

artist - Mr Mohan Kumar, who is one amongst

UNESCO’s 40 chosen artists of the world, and is a

recognized green activist. Over fifty of his works of

art aptly embellish MDC Lonavla – a LEED rated

Green Building.

A brick and mortar structure is merely a building

until life in the form of art is blown into it. L&T

Construction’s Corporate Communications

(CCD) team had aptly conceptualized and added

befitting work of art along the corridors, foyers

and other vantage points to provide the much

needed relief and also to provide the visitors an

element of wonderment and serenity.

The artist’s signature style includes a human

soul seen in the midst of a large terrain - amidst

landscapes, mountains, jungle, river and snow-

clad mountains – engaged in a silent search for

knowledge and perhaps in ‘self-reflection’. These

paintings are also reflective of the minds that dwell

and conquer business and enterprise at Larsen &

Toubro - India’s premier conglomerate.

Apart from the paintings, CCD had also made

effective use of technology to bring alive lush

green vegetation on the walls of the atrium in

the dining hall. As one ascends the staircase to

the upper levels, the huge wall presents a picture

of wilderness giving the visitor feel of tranquility

and a reminder of how close he/she is to such

natural treats at Lonavla. L&T Construction’s

Corporate Communications team conceptualized

and commissioned these inspiring themes which

have been artistically reflected on the walls of the

learning halls at MDC Lonavla.

Breathing life into a green campus


to drivers, the driver’s dormitory has been created with levels according to the topography of the site along with facilities and amenities arranged around an open courtyard creating a lively space.

Entrance gateway

The entrance gateway was designed to project a world-class image of the company. An elliptical archway, extending into the limits of space and merging with vertical and horizontal

planes, projects the multidimensional facet of L&T.

The two columns in the center extending into the space symbolically represent the enviable stature of L&T. The composition is balanced in both planes by adopting the same elliptical shape in plan and section.

The gateway along with the security cabin is designed to have a complete control over the entry and exit of visitors into the campus. It is achieved by providing clear glass on both sides to enable a direct view to function efficiently and to restrict trespassers.

Scope of work

The broad scope of work for MDC Lonavla includes concept, design and construction of “Management Development Center, The Temple of

Computer centre in the learning centre

Significant milestones

L&T’s Management Development Centre – The Temple of Learning is one of the most prestigious and challenging projects. In the pursuit of delivering an International class T&D centre, L&T has achieved many milestones including the first and most important, an architecture that would blend with the immaculate environs of Lonavla.

Created an additional class yroom called ‘Golden Sun Rise’ of 32 capacity including all interior, services, furnishing and furniture within a record time of 34 days

L&T Construction’s Buildings & Factories IC have done a stellar job at MDC Lonavala. L&T ites who visit the centre after a long interval are amazed at the facilities built. Not just the sheer size, but the layout, design, quality of the buildings, the finishing and the total impact. Professors from leading academic institutes, both domestic and overseas say that L&T has in the true spirit of an Engineering and Construction Company created a “landmark” which will be a benchmark globally for Learning & Development institutes.

In 2007 when we were planning to expand MDC, what was central in our minds was that in catering to the ever growing demand for booking MDC for training, we should not just build a run-of-the-mill facility. L&T is India’s leading Engineering and Construction Company, and, our learning centre must be world-class, a model that other companies would want to emulate.

Further, knowing that learning ambience plays a vital role in ensuring the true success of any L&D initiative, we decided that the layout would be such as to create the feeling of space, and that we would landscape the

surroundings in a manner that greenery would be in focus from all quarters, so as to harness the creative energies of participants.

The buildings were designed to cater to groups from a batch of 20 to 300 participants. We hoped that all future Leadership Development initiatives and Top Management gatherings for “workouts” etc., would happen at MDC. Hence we designed the Campus to accommodate a little over three hundred residential participants who would have sufficient learning rooms and dining halls to ensure all could dine at the same time. Games and recreation facilities that would be available only in leading star hotels and clubs were also made available.

Our plan may have seemed to be a dream to many, but the MDC project team has created, designed, built and delivered a facility that actually has gone far beyond what we planned, imagined and dreamt of.

Challenges

Lonavla being a hill station and a tourist attraction, mobilization of labour was a herculean task. L&T had provided basic necessities and good accommodation to cater to the

comforts of the workmen. The terrain also made procurement of material and transporting it a challenge. From the weather point of view, the monsoon was also quite rigorous stalling the project progress during the season. Therefore, the structural work was completed before the monsoon began and all the finishing activities were planned during the monsoon in order to speed up the progress.

Safety

Safety, being the integral culture at L&T was one of the top priorities at MDC, which has set an example by achieving more than 05 million lost time injury free man hours. This was possible due to the ownership spirit of the entire team that completely abided by the existing EHS culture. Implementation of PPE’s was done through motivation

scheme, periodical meetings, daily PEP talks, poster display and tool box meetings among staff and workmen.

QualityIn line with maintaining the high standards set by L&T, the job quality was maintained at high levels right from Phase I. L&T’s in-house quality lab, checked and certified the quality of each and every material that was being procured. The project team ensured that the construction was as per the specification, methodology and checklist to avoid discrepancy in the final product. A high level of emphasis was laid on creating mock-up for all key activities before executing the original scope.

765/400kV Substation @ Unnao


In line with setting benchmarks in the engineering and construction industry, L&T has

been involved in the setting up of the country’s first ever substation for evacuating power at two voltage levels of 765 kV and 400 kV in the state sector. Uttar Pradesh Power Transmission Corporation Limited (UPPTCL) sought implementation of the construction of 765kV transmission system between ANPARA generating station and Unnao Sub-station. Crompton Greaves Limited (CGL) was awarded the job as the main bidder which was subcontracted to L&T. L&T was entrusted with complete engineering, certain supplies and complete installation of 765kV / 400kV transmission substation at Unnao in the state of Uttar Pradesh.

Scope of work

The scope of work included design, procurement and installation, testing and commissioning of 765kV switchyard and 400kV bay extension to be completed within a period of 18 months. The project was awarded on 29th of January 2010, and after forest clearance, the land was handed over by the client on 7th May 2010.

The substation has the unique feature for evacuating power at two voltage levels, such as, 765kV and 400kV using 2x1000 MVA interconnecting transformers. The existing 765kV transmission line, presently operating at 400kV, has been diverted and reconnected to the new 765kV substations at Unnao and at

Anpara-C. A second 765kV circuit will interconnect Unnao to Anpara-D. 400kV supply from transformer downstream shall interconnect to the existing 400kV substation.

Major scope of work – civil

Construction of three control buildings, two store shed buildings, DG and fire fighting buildings, and mulsifier tank three oil collection pits, three underground and one overhead tank, 4177 m of concrete road, 5282 m cable trench, 494 equipment foundations, 36 tower foundation, 135000 sq.m of yard development, 32121 cu.m stone fill, 1703 m switchyard fencing and 8.5 km of drain for storm water disposal.

plant communication, CCTV & Access Control Equipment (ACE), substation automation system and complete testing and commissioning.

Design complexity

The design team of the client side were keen to take additional efforts to standardize and establish systems, since the 765kV Unnao was the first of its kind substation. The geographical distance of consultant M/s SNC Lavalin (core team in Canada) coupled with a very small team of two persons (each from electrical and civil design) from UPPTCL responsible for inspection as well as design approvals was a challenge.

Most of the equipment from various vendors were designed and put into operation for the first time at 765kV voltage level, hence a lot of interfacing and coordination was

needed. Equipment such as clamps and connectors from Klemmen, Hardware from ITTPL, Transformer’s from CGL, Isolators from S&S, Circuit breaker from CGL, TP Y class of CT’s from Koncar etc. . Owing to this, the client was doubly conscious of quality and for performance related issues thereby making approvals a tedious process.

Since a majority of equipment had to be supplied by the client all inputs were required for finalizing equipment foundations, structures, cabling, earthing and protection schemes. In-ordinate delays in providing these inputs put considerable pressure on L&T’s design team and it also had a cascading effect on the execution team. Regarding cable trench design, client insisted that all equipment drawings was to be frozen first and also restricted the maximum size of cable to 10 core

765 kV HV AIS Equipment


resulting in substantial delays in approval of critical cable trench execution activities which needed considerable gestation period for completion.

Other unexpected issues included introduction of swing calculation for conductors (not a standard practice in switchyard), revoking of approved sag tension calculation, client’s insistence on un-cracked section for foundation design, etc.

Challenges faced

Unnao was the first project in the country to have come up in the state sector with stringent deadlines for completion in 18 months as against a normal 24 - 28 month schedule for similar such projects. However, unlike other projects, L&T had to do simultaneous engineering and

execution for entire transformer, line and bus reactors bays (8 nos. of 765kV Bays and 2 nos. of 400kV bays) leading to massive engineering, execution and commissioning works that had to be completed in a very short time.

Delays from client side on areas such as approval of soil investigation, forest clearance and location for dumping surplus earth further increased the pressure on timely completion.

Unnao also faced unprecedented rainfall during the execution phase which completely inundated the low lying areas of switchyard, thereby halting the work for almost a month’s time. Massive efforts of digging trenches through the entire switchyard area and dewatering helped resume work.

L&T sought and got the approval for design mix resulting in savings in cement, however, this also meant that all concreting works had to be carried out using mini batching plants where the mix of raw materials can be controlled. This mandated mobilization of contractors with such equipment at site.

Client provided a two day shutdown for erection of 3 bays of 400kV area including removal and replacement of existing conductors. A detailed Work Breakdown Structure was made and adequate resources were mobilized to complete the challenge.

L&T identified the requirement of online NAS (National Aerospace Standards) filter and online NAS counter which came as a new

Final lift of 14 m High fire-wall


requirement for oil filtration in 765kV Transformers and Reactors. The project team identified able associates to carry out the same for the first time in India. To support the stringent requirement of TBEA regarding total gas content special syringes were used for sending samples to the lab.

Since execution of 765kV substation was a first of its kind experience to L&T, the existing safety methods were reviewed and found inadequate. L&T implemented several new safety techniques which emerged out of several brain storming sessions resulting in a Zero Accident accomplishment and achieving 3 million lost time injury free man-hours!

In order to avoid the cumbersome, expensive and painstaking process of sending frequent samples to lab, L&T set up a quality lab at site which was acknowledged by the client due to apparent advantages.

The controller for controlled switching in the Circuit Breakers (which was earlier situated in field) was decided to be shifted to control room. This resulted in

overhauling of cable schedule and termination details and called for additional panels to fit in these controllers. Further, since DC voltage was pegged by client at 110 V (as against a standard 230 V) it was observed during commissioning that breakers were not tripping satisfactorily due to high voltage drop. A shutdown programme for cable laying, termination and breaker replacement was made and completed ahead of client expectation leading to minimal delays.

Milestone achievement

Since the land area was low lying, the client’s decision on raising the level created an inordinate delay. This delay put tremendous pressure on execution team as the tower drawings were on hold. Similarly issues like buoyant effect due to submergence and client’s insistence on designing the foundation as un-cracked section also put the tower work on hold. There was a cumulative delay of two months due to these delays. However, with fast tracking and parallel construction activities these delays were mitigated and speedier processing at the subsequent lattice structure erection works which was on critical path ensured faster completion.

There was considerable delay in approval of foundation for transformer and reactors, at the same time, there was pressure to have the structure ready by the time the equipment were scheduled for arrival. With barely fifty days to complete nine foundations (3 for transformers, 3 for line reactors and 3 for bus reactors) L&T team planned a detailed and micro

level sequence and engaged three agencies simultaneously to achieve the milestone.

In a similar situation, the control building too, was scheduled to be completed before the arrival of interface control, relay and switch gear panel. Design and approval of cable philosophy and trench sizing delayed the construction process substantially. With detailed planning and close monitoring of respective work packages the assignment was completed in time after working in multiple shifts.

Another important milestone to achieve was the completion of 495 numbers of equipment foundations, 5.2 km outdoor cable trench of various sections and simultaneous construction of internal roads and drainage systems. All these activity

fronts were opened simultaneously which made the work site cramped for space. Addition of resources like men, material and machinery to carry out the work round the clock eased the situation considerably. The project also faced an early monsoon with record rainfall leading to flood like situation. With no natural access for self-dewatering, L&T designed and made temporary drains and sump pits along with dewatering pumps to drain the water out of the catchment area. This was very crucial as L&T could continue critical activities like outdoor cable trench, support installation, cable laying, equipment erection, installation of entire fire fighting system (Fire hydrant, pump House, HVW Spray for transformer & reactor and fire alarm system) in the monsoon period itself which

was later found to be an effort that made all the difference for an on-time performance.

As the client has a contract with LANCO incorporating reimbursement for losses due to deemed generation there was considerable pressure on project completion and commissioning. However, since the existing line was used for power evacuation at 400 kV, the client were reluctant to provide 765 kV supply for testing and commissioning. L&T project team readied the switchyard bay-wise which opened an opportunity for parallel testing and commissioning so that mechanical completion was achieved by September 2011. These activities were divided into four modules due to which L&T could back charge 400 kV equipment and associated

Project site inundated during the monsoons


line on 4th of November 2011 and subsequently commissioned successfully, the country’s first 765 kV transmission substation on 5th of December 2011.


L&T had identified in the very beginning itself that the only way to complete the project in the scheduled time frame despite all odds was to implement complete mechanization of both Civil and Electrical activities.

The scope of cable trench was 5282 m and the period of execution was only 90 days. Since the target achievement per day was high, aluminium formwork method to execute cable trench work was implemented and executed to a great success.

There were 14 firewalls which had to be completed before transformer and reactor erection since there were little clearances available between firewall and radiators.

Through indigenous efforts, L&T was able to design a suitable formwork to complete the firewall in a short duration of 12 days.

For completion of footpath, 3.5 lakh interlocking tiles were required. L&T planned and initiated onsite fabrication of the same to ensure timely availability and superior quality.

Understanding the importance of design approvals and the limitation

of client, a localised setup of design team helped minimise delays and the drawings were made available for the execution team on time for action.

L&T identified early-on that fire-fighting activities were running on critical path, therefore imported thread cutting machines were deployed and blanket waiver was arranged from client for material inspection to ensure that the work was completed in totality in a record time of 3 months even during peak monsoon period.

To facilitate execution, various features were built-in during the design stage itself, such as replacement of massive trapezoidal drains with hume pipes, shaping over-head water tank as square which saved massive construction time while reducing costs.

Vendor sourcing and supply chain management

Realising the importance of timely availability of major client supplied equipment L&T maintained seamless interface with clients and other vendors on a regular basis.

For instance, the 765 kV transformer and capacitive voltage transformer was a critical component of supply. Most organisations manufacturing 765kV transformers in India had

a high sales backlog buoyed by demand and hence were unable to deliver within the time frame and the prices were also very high. Considering this, L&T introduced an overseas vendor named Koncar (Croatia) who

was not only able to deliver these critical equipment in time but also at a reasonable cost as well.

To avoid permit issues and long lead periods, L&T developed local vendors who could supply smaller items in a shorter period and at a lesser cost.

Hindalco

Aluminium smelter and captive thermal

power plant for


Hindalco, the flagship company of the Aditya Birla Group is the

world’s largest aluminium rolling company and one of the biggest producers of primary aluminium in Asia. Hindalco envisaged the setting up of aluminium smelter cum power project at Mahan near Singrauli in Madhya Pradesh. The Mahan Aluminium Project includes a 359-ktpa Aluminium smelter and a 900-MW captive thermal power plant. L&T is also doing the Coal Handling Package in the captive thermal plant, the details of which is covered in a separate section at the end of this article.

One of the most crucial activities during the execution of 359 ktpa Aluminium smelter was the construction of two Pot Rooms; each measuring 1.2 km consisting

of 90 bays. The pot rooms required 180 columns measuring to a height of 7 m. The 90 bays in the Pot rooms were divided into

two parts of 45 each having a central passage.

Since the tolerance limits for the civil structures were a stringent +0 to – 5 mm, the construction proved to be very crucial and required constant monitoring from quality point of view. The erection of precast elements weighing from 12 to 28 t was one of the most difficult tasks as a 150t crane was used among confined spaces to erect these elements.

Among one of the first-of-its-kind initiatives in the country, was the implementation of static roof ventilation systems in Pot Rooms. The wings of the ventilation systems were specially designed in such a manner that most of the

waste gases would be effectively released but not even a single droplet of water would enter the pot room from outside. This ventilation system was erected at a height of 16 m was is highly appreciated by Hindalco.

In order to maintain the electric conductivity throughout the pots, all reinforcement of smelter packages were tied using welding process and not by the conventional binding

bars. This is a crucial requirement as the plant process will not happen if the conductivity is not uniform. The quality of welding is ensured by a process consultant representative and an electrical engineer was specially deputed for ensuring the electrical conductivity. Another important point to ensure is that a one lakh ohm resistivity is required for ensuring proper insulation of the Pot Structure with other structures. Through appropriate planning and perfect execution, L&T had completed all activities required for the commissioning of stageI well before the scheduled time to the utmost satisfaction of the client.

Challenges faced

Due to remote location of the project site and the associated geographical limitations, the availability of material was a big constraint. With the nearest open market being located 250 km away, procurement of material was a big challenge. In order to mitigate this challenge, the project team went with proper planning and

scheduling from the very beginning of the project and also developed local vendors for ensuring timely receipt of material at site.

As part of the corporate social responsibili ty and a commitment towards the society, L&T had provided employment to the project affected people who were displaced due to the acquisit ion of land by the client. Since most of these people were unskilled, they had to be trained extensively to employ them suitably for various construction activit ies.

The project site also witnessed heavy monsoons during the months of July and August 2010. The heavy rains brought the project activities to a complete stand still. The project site was completely inundated with an

entire boom placer completely submerged underwater. Further, material such as formwork, tools and tackles had got washed away and the whole project site turned into a flood like situation.

Pot Super Structure Works (PSS)

The scope comprises of fabrication and erection of 362 Pot Super Structures, two handling beams. The highlight of the project is that ‘AP 36 technology‘ was used for the first time in India and Aluminium work for positive riser was carried out for the first time by L&T.

The fabrication yard of pot super structure covers an area of 30,000 sq.m that comprises of 36 workstations (including16 workstations for positive riser), Intellectual Property office, yellow block, etc. All the structures had to get validated from Aluminium Pechiney (AP). The fabrication of PSS is a very critical job as there are a total of 66 types of material used. Every single PSS consists of 38 sub-assemblies made from a whopping 5152 components. Of these components, 738 are steel components, 1274 are equipment components and 3140 are aluminium components.

The welding length of one PSS is 726m and for Positive Riser it is 324 m which requires aluminium welding. The client / AP consultant checks 2979 dimensions out of which 1158 are in PSS and 1821

are in Positive Riser. The project team faced some quality related issues such as porosity in welding and roughness during machining of aluminium bar. L&T’s quality engineers worked fervently on the porosity issue and resolved it by using a mixture of Helium and Argon gas (He-15%+Ar85%) for aluminium welding instead of the usual Argon gas. This was done after a lot of research and conducting various tests.

Challenges

Getting “IP Validated Company” for the fabrication of IP Product was a challenging task. The task of maintaining IP system as per approved Intellectual Property manual as desired by Aluminium Pechiney (Technology Supplier) was also difficult. For instance, mobile phones with camera are not allowed in the IP premises and only authorised employee can enter the IP protected workshop, therefore employees should sign the confidentiality agreement, etc.

All IP drawing / confidential document were to be stored only in the yellow block at the

designated IP protected area and all the printing of IP drawings were to be done only in yellow paper (for traceability of confidential document).

All Jigs and Fixture were developed by L&T after application of engineering method by site engineers at the project site itself.

Aluminium machining and Aluminium welding was very critical and a lot of research was carried out to finalize the desired welding quality and purity of argon gas.

process starts from Apron conveyor of 104 TPH capacity. The rejected rodded anodes and spent anodes will be initially stripped out in the butt-stripping machine of Anode Rodding Shop (scope of client), and will be fed (maximum dimension of 800x250x650 mm) to L&T’s Apron Conveyor through chutes.

Scrap paste from various areas will be fed to the hopper by pay loader (not under L&T’s scope). The carbon from hopper will be drawn by vibrating feeder of 25 TPH, which will feed the apron conveyor.

The rejected green anodes (1560x655x665) from Green Anode Plant (scope of client) and rejected baked anode (1550x650x660) from Anode baking furnace (scope of client) will be placed on Apron conveyor by an electromechanical Jib Crane (L&T’s scope). The first feeding point on apron conveyor shall be

the scrap paste feeding from the hopper and then the full anode feeding by the jib crane.

The apron conveyor discharges the carbon to Outotec’s 35 TPH Single Toggle Jaw Crusher. The crusher reduces the grain size to 0-300 mm. The Jaw crusher throughput shall be received by an inclined belt conveyor, which discharges materials into a surge hopper, placed above L&T Kansbahal’s secondary roll crusher. The roll crusher shall be fed by a vibrating feeder fitted below the surge hopper. The roll crusher further reduces the grain size to 0-80 mm. Roll crusher output shall be collected by an inclined belt conveyor for onwards storage at Green or Baked Silo.

L&T has introduced reversible shuttle conveyor on the top of silo for four feeding zones. This will help reduce the dead zones of Silo.

Each belt conveyor carries carbon through two isolated magnetic separators. The storage capacity of baked and green silo is 1600 t and 400 t respectively. Apart from this scope, L&T is also providing Vacuum Floor Cleaning System and Bag Filters for dust prevention in the shop.

Special Equipment

Apron Conveyor: L&T Kansbahal works has designed and manufactured India’s longest (76.76 m) VFD operated apron conveyor in non-ferrous sector with 104 TPH rated capacity for Mahan Carbon Recycling Shop.

Jaw Crusher: Outotec has designed and manufactured 35 TPH Single Toggle Jaw Crusher with a dead-weight of 110 t. The L&T Mahan project team erected the jaw crusher on a slab with a height of 4.5 meters using a 150 t capacity crane.

Crusher House of Carbon recycling


Alumina Silo

The construction of 21000 t capacity alumina silo measuring 43 m in height with 34 m in diameter was a very demanding job. The task of erecting structural roof weighing 335 t over both the alumina silos

and pouring concrete slab over the structural roofs was one of the toughest challenges. Both silos were executed in tandem in order to meet the client’s schedule and to complete the job within the stipulated time period. One of the major highlights of silo was that it was constructed in 3 steps. The scope also included the construction of compressor house, blower room

and screen house apart from a coke unloading shed.


Execution started with casting of 460 piles - 230 piles for each silo. Firstly a raft comprising major concrete quantity of 2500 cu.m was cast after completion of the piles. After pouring the raft, a wall of 8 m height was made. Over the wall a1100 cu.m slab was again cast. After casting the

slab, slip formwork commenced. Slip formwork was completed in 35 days at an average rate of 1.2 m achieved per day.

Erection of Alumina Silo Roof

Strand Jack system was used for erecting the 330 t structural roof of alumina silo. For the erection, a 110 t temporary structure was fabricated which was designed to be used again for executing similar types of work. 4 strand jacks, each having

180 t erection capacities were used. Strands of 18 mm diameter were used for erection and 450 mm lift per stroke was achieved per lift. By

Challenges

Hard rock

The Mahan Coal Handling Project site encountered massive hard rock which was not anticipated during the early stages of the project. Being a green field project, the people living in the area adjoining the plant had to be mass evacuated for carrying out the blasting operations. Controlled blasting operations in hard rock areas were subsequently carried out and approximately 3,15,000 cu.m of hard rock was excavated upto a depth of (–) 22 m.

Crusher & Crusher Drive on Floating Deck Slab


Front handing over

Graded land is to be provided to L&T for commencing construction activity. Process of land acquisition ran slow in the initial stage of the project

despite many efforts by the client. The area grading in the hard rock was another time taking activity. Both these process resulted in considerable delay in front handing over, which was another big challenge to cope up with the stiff time schedule.

Engaging project affected people

The engagement of project affected people was imparted on L&T by the client. Since the villagers were mostly raw hands, they had to be trained in specific areas of requirement. About 180 people were trained and engaged by L&T in its daily construction activities.

Terrain

The project location is situated at finish ground level of 397.00 m elevation with the surrounding areas having FGL as 399 and 400 m. Therefore during the monsoon period, the project team faced a lot

of logistic problems as there was inundation of land. Mass dewatering was done to restore work and to enable logistics to the project site.

Project period

The civil and structural fabrication jobs of such large magnitude were to be completed in a short period of 20 months. It was a great challenge to execute, as a lot of planning and interface management had to be in place for the smooth progress of the project activities.

These challenges were overcome through meticulous planning and implementing the right construction sequence with frequent inter discipline interaction.

Mr.Naik’s mantra has always been ‘value creation’ – this study reaffirms his success in putting his concepts into practice. The study stands out among other surveys for the rigour of the processes used and because it was carried out by internationally recognised professionals. The ranking was based on a comparison of 374 CEOs of 202 publically traded companies on the Indian stock markets, drawn from the S&P CNN 500 since 1998. The CEOs were ranked based on the shareholder returns that they generated during their tenures.

The ranking combined three measures: country-adjusted company returns, industry-adjusted company returns and market capitalization change.

L&T Construction’s Solar Business receives highest CARE rating Ministry of New and Renewable Energy (MNRE) has launched Jawaharlal Nehru National Solar Mission with an objective to promote the use of renewable sources of energy and setting up an environment which will facilitate increased penetration of solar technology in the country through grid connected and

off-grid and decentralized solar power projects. The mission has envisaged that RESCOs (Renewable Energy Service Company) and System Integrators obtain an accreditation from a rating agency like Credit Analysis & Research Ltd (CARE) so as to enable them submit project proposals directly to MNRE to avail capital and interest subsidy for their proposed off-grid & decentralized solar power projects .

CARE’s Grading is aimed towards categorizing Renewable Energy Service Companies (RESCOs) and System Integrators into grades based on their performance capability (such as track record, project management, etc.) and financial strength (such as networth) to undertake off-grid & decentralized solar projects.

L&T Construction’s Solar Business has been given the highest rating - ‘SP1 A’ and has been certified as a highly rated RESCO (Renewable Energy Service Company) and system integrator, enabling it to become one of the most reputed channel partners of MNRE to execute off-grid solar power projects. With this accreditation, L&T Solar is poised to set new benchmarks in the Indian Solar industry.

National Record on Fastest Erection & Commissioning of M1 Batching plant at Cognizant, Shollinganallur

Adding to the exceptional credentials of setting benchmarks, L&T Construction has set a new national record by erecting and commissioning a M1 batching plant at Cognizant Technology Solutions, Shollinganallur in Chennai.

As a process of mentoring safe and expeditious erection process, a trend of meticulous planning before actual execution has been initiated by Chennai Cluster recently. This trend began with the erection of MC 205 B tower crane with 60 m Jib erected, commissioned and handed over to TCS, Kochi project site in 15 hours. Following this was the

erection of CTT 231 with 70 m Jib that was handed over in 13 hours consecutively. This initiative has been implemented with great success in many sites such as HCL Technologies, Cognizant, TCS, etc.

This effective trend had paved way for the creation of a new national record in the fastest erection of a batching plant at CTS, Sholinganallur. A batching plant becomes one of the most indispensable enabling structures for any major project site. The delay in commissioning of a batching plant usually has a cascading effect of delaying the project execution.

KAPP 3 & 4 achieves 310 cu.m of heavy density concreting in a single pour

Heavy Density Concrete was pumped for

the first time in the history of Indian Nuclear

Construction!

22nd February 2012 was a field day for the

project team at Kakarapar Atomic Power Project

(KAPP 3&4), Gujarat. The team successfully

pumped 310 cu.m of Heavy Density concrete in

a single pour! This unique concreting done for

Unit#3, Calandria vault’s Base Slab for India’s

First 700MWe Atomic Power Project, is considered

a milestone achievement using innovative

construction methodologies.

The Calandria vault is a stainless steel reactor

vessel and is considered the heart of a Nuclear

Power Plant. The concrete used is therefore of

heavy density, having unit weight of over 3700

kg/cu.m. Maintaining this density is crucial and

is a special requirement for the prevention of any

radiation.

In the past, heavy density concrete was placed

using only tower cranes and buckets. Owing

to the high density of concrete, it was not

possible to pump the same. L&T’s Quality Control

team at KAPP has successfully designed and

developed “Pumpable Heavy Density Concrete”

(H35/20/19°C) with Hematite aggregates and

micro silica.

For the first time in the history of Indian Nuclear

Construction, Heavy Density Concrete was

pumped and placed through static boom placer

uninterruptedly with a rate of pour of 20cu.m/hr.

Thus, cold joints were avoided in spite of the large

size of the pour.

The advantage with this innovation is that

the tower cranes could be kept free from

concreting and could be utilised effectively

for feeding other construction materials.

Various teams from Planning, Batching Plant,

P&M, QA/QC and Nuclear Building#3 worked

with dedication and commitment to achieve this

benchmark.

Earlier In February 2011, the KAPP 3 & 4 project

team had successfully placed the single largest

normal concrete (N45/20/19°c) pour of 5100

cu.m for ‘Reactor Building 3’ within a record

time of 72 hrs. Kudos to the project team on this

significant achievement!
