If airports reflect the character and personality of a city, then the new Mumbai International Airport sports all the verve and vibrancy of India’s throbbing commercial capital. And, Larsen & Toubro, is proud to have created a gateway for the world that is truly a landmark of the future. Built to exacting specifications and by overcoming innumerable challenges, this very complex brownfield project is yet another sterling example of L&T’s engineering prowess and reaffirms its leadership position in providing total infrastructure solutions for a new India.

A shining example of

world-class engineering!


What is more difficult than making an elephant dance?

Making a peacock dance!Inspired by the dancing peacock, India’s national bird, the picturesque new Terminal 2 of the Chhatrapathi Shivaji International Airport is a resplendent icon of modern infrastructure.

And it took a lot of doing!


project requires extensive planning; time bound schedules and constant monitoring to ensure timely execution of elaborate engineering. T2 of the Mumbai International Airport represents one of L&T’s best performances and reflects the flawless teamwork and smooth coordination that have become synonymous with us. Now, that the airport is fully operational and has become an important landmark of the

The new Terminal 2 of Mumbai International Airport is truly globally benchmarked for its architecture, design, quality and cost. I have not seen many, in fact, any other airport even outside India that is as good as this one! Unique in terms of the synergy of aesthetics and functioning, this is easily one of the most beautiful airports in the world.

The overall framework and concept for this kind of gigantic

country, every time we pass through it, we will cherish and take pride to have been associated with this dream project.

It is good to have associated with GVK who also share our ideology in partnering only with the best to bring about perfection. I am glad that L&T was a part of creating Mumbai’s first public building that also doubles up as an art project. It is a national symbol!

A. M. Naik Group Executive Chairman

We started our MIAL journey almost 6 years ago and as EPC contractor for the entire project, our challenges were mindboggling! It was one of the most complex brownfield projects that had to be executed without disrupting the operations of a fully-functional airport! We had to double the passenger capacity of India’s busiest airport by building a massive infrastructure right in the heart of Mumbai with no extra land to expand, no time to shut down, highly sensitive from a commercial, political and security point of view; and finally, world-class quality to be delivered in a limited time frame.

The new terminal building, constructed over the footprint of the existing international terminal building, on a built-up area 4 times larger was made possible by demolishing several existing structures. On the Airside, we had to reconstruct two existing runways with defined time windows to carry

out the work. Simultaneously, we had to co-ordinate with airline industries across the world through NOTAM that gave no room for failure or slippages. A concourse was built to join the two terminals while a 3.3 km, 6-lane elevated corridor connected the airport with the Western Express Highway to address Mumbai’s traffic problem. The 83.8 metre tall ATC tower and the terminal building, which incorporates the dancing peacock in every element is an engineering marvel. The latest technologies such as rubbilization for apron construction, high rise jaw crushers for dismantling, hot tapping for diverting live fuel lines, carbon reinforced fiber technology for strengthening an existing bridge under the operating runway, erection of 28000 tons of structural steel roof using launching girder over 40m tall highway trusses, were all a part of the mechanization strategy adopted to quicken this project.

The magnitude of the project was almost too huge to consider. Every day about 15,000 workmen, 1,000 engineers, 200+ sub-contractors and some 4000 of their staff turned up for work. 250 engineers and architects formed the on-site design team while expats were mobilized from the world over for various functions. Project planning, which was globally benchmarked, involved handling of more than 200 specialized national and international agencies.

At the end of the day, we had to live up to the expectations of a lot of stakeholders – the client, the airport authorities, the Government, the local statutory bodies – but none as big as the passengers themselves. And we did that in style, which is typical for every L&T executed project.

Hats-off to the entire MIAL project team for having created such a marvelous edifice!

80,000 light fixtures, 750 kilometers of conduiting and another 250 kilometers of HT/LT cables, 940 chandeliers, 3,000 CCTV cameras, some 26,000 data points, a ‘Diya Wall’ with 1,000 LED lamps … the numbers are totally awesome but that was our challenge in the Electrical and IT space. It was our responsibility to breathe life and infuse light into this huge structure. The magnitude of the task was huge that called for micro-planning. Each and every aspect, however insignificant, had to be checked and approved because back-tracking would have cost us time, which we did not have and erosion of our margins which we could not allow. We were dealing with a plethora of suppliers from around the world and had to be ever-vigilant that deliveries and installations were happening like clockwork. Several new technologies and methodologies were adopted to fast-track the project like using multiple conduits instead of cable trays and flexible cables for wires. Our team was young and dynamic driven by the urge to create systems that shall suffer no downtime! At the end of the project, we are proud for having contributed in the creation of a masterpiece.

Niranjan Simha Project Director

The project was very complex with multifarious challenges that had to be resolved, phase-wise, as we proceeded and kudos to the entire MIAL project team for having succeeded despite

seemingly overwhelming odds. Some of the operative words that describe the MIAL project are ‘Planning’, ‘Co-ordination’, ‘Quality’, ‘Execution’ and ‘Timeliness’. Managing the huge

work force was like leading an army with so many people, who were experts in their various domains, drawn from various parts of the country and the globe. Since

we were working to stringent deadlines, it was imperative to get the right resources at just the right time. Overall, it was one of our toughest assignments but we were able to deliver a world-class facility on time, thanks

to the qualities that sets L&T apart, its design excellence, construction capabilities, the freedom to take calculated risks all brought together by unmatched teamwork which contributed to the creation of this beautiful edifice.

Rajesh KanadeHead - Project Planning and Control & TC; Project Manager - Airport System

For L&T, MIAL was the fourth international airport project in an Indian metro, and although the considerable experience gained from these previous projects did hold the team in good stead, we were yet faced with a whole lot of challenges hitherto not faced that required new and innovative solutions. Considered perhaps the world’s most complex brownfield airport project, the planning for MAIL combined several unprecedented dimensions and the team faced them head-on. Our goal was to create a global landmark. Sharp planning and committed implementation, coupled with rigorous follow-ups, saw the project progress at unbelievable speeds. Once commissioned, the task of testing, commissioning and successfully integrating over 75 MEP, airport and IT systems and carrying out 200 project operation trials was arduous but completed, thanks to seamless cross-functional interfacing. The sophisticated electro-mechanical and IT enabled BHS, HBSS, VHT and PBB airport systems called for impeccable standards of execution and commissioning. The remarkable six-lane elevated corridor constructed right over a busy operational at-grade road has become a marvelous dedicated access to the terminal. The success of the MIAL project was indeed a perfect performance through flawless teamwork and smooth coordination.

C.J.A. DavidrajDeputy Project Director – Finishes

‘Making a thousand peacocks dance’ was the vision with which the finishes team took up the MIAL project. Every single square inch of the terminal, be it interior or exterior, had to have the touch of perfection to not just create a landmark project, but an edifice that would be regarded as one of the world’s most stunning airport terminals. The numbers

were mind blowing, 80,000 sq.m of GFRG canopy, 1.83 lakh sq.m of granite, 1.10 lakh sq.m of metal ceiling and 30,000 sq.m of carpet. With such mega volumes

involved in every procurement item, standardisation was indeed a challenge. Detailed method statements followed by mock-ups and strict adherence to the charted sequence of execution made implementation seamless and smooth. The swank finishes have truly created the intended ‘wow’ effect with even the Prime Minister of India terming the terminal as ‘The Pride of the Nation’.

J. Gopalakrishnan Deputy Project Director

When we embarked upon the project, the entire footprint of the proposed terminal measuring 125,000 sq.m was occupied by various facilities. The team’s primary task therefore was to plan and create the required footprint, inch by meticulous inch by demolishing to commence construction. This called for consistent out of the box thinking from the team in terms of construction sequences, erection methodology and innovative equipment to be deployed. ‘Getting it right the first time’ was the operative phrase for the planning team simply because there was neither the time for rework nor room for deviation. Activities were planned and scheduled in tandem such that when combined with faultless execution, it would bring out nothing but the expected results. An indomitable spirit, steely determination and unfailing commitment became the work culture at the MIAL project site which transformed an ambitious dream into reality. The successful completion of the MIAL project has greatly boosted the self-confidence and pride of everyone involved in it.

M.V. Satish Sr. VP & Head - Buildings & Factories

As the ever-throbbing commercial capital of India, Mumbai has a number of facets to be proud of and we are honoured that we have been able to add to that long and illustrious list with a gateway that is truly world-class and representative of the exuberant spirit of Mumbai. Our journey commenced with a vision to create one of the most sophisticated, state-of-the-art and picturesque airports in the world and I am absolutely delighted that we have been able to translate this lofty vision into breathtaking reality. The challenges that we encountered at MIAL were unique that required an equally unique and robust team that could drive the project with passion. And they did so quite splendidly! The MIAL project has showcased to the world, L&T’s construction prowess and seamless project management capabilities. Perhaps, what is even more satisfying for us is that through this project, we believe, we have been able to take ‘stakeholder satisfaction’ to an all-time high. After all, we are not only in the business of creating landmarks of the future, we are also transforming lives for the better.


40 million by 2015

A master plan was developed with a vision and framework for the long-term but at the same time realistic in the short term, to build a swanky world-class airport factoring in the limitations and challenges. The aim was to increase the present capacity of handling 25.6 million passengers and 0.5 million

tonnes of cargo per year to close to 40 million passengers and about a million tonnes of air cargo shipment by 2015.

L&T at MIAL

Larsen & Toubro (L&T) was appointed by MIAL as the main contractor to design, procure and execute the works on the terms and conditions of the contract. As the airport was operational, the users would continue to use the airport during the performance of the work. L&T was to carry out the works with minimal inconvenience to the

airport operations and enable MIAL to meet Operation, Maintenance and Development Agreement (OMDA) requirements for such performance.

L&T was engaged in the planning, design, engineering, procurement, construction, testing and commissioning of the airport facilities on an EPC basis. The existing airport site was land-locked by the city and the biggest challenge for L&T in executing the brownfield

Mumbai International Airport was the country’s busiest airport until 2008 after which Delhi gained the pole position. Put together, Mumbai, Delhi and Chennai airports are estimated to handle more than half the traffic of South Asia.

In 2010, CSIA was ranked the 30th busiest airport in the world in terms of cargo with 671,238 tonnes handled. In 2011, the airport was ranked the third-best in the world in the 25–40 million passengers category by Airports Council International. Also in 2011, the airport was the 44th busiest in the world with 30,439,122 passengers handled, registering a 7.6% growth rate over the previous year.

Today, with a dedicated six-lane elevated corridor leading in to the airport that features world-class amenities, the Chatrapathi Shivaji International Airport is poised to set several benchmarks in India’s civil aviation sector.

Project planning & control Winning takes planning

Constructing a brownfield airport in the middle of a fully functional airport which was, by the way, also one of the busiest in the world, called for several levels of planning, deliberations and brainstorming to evolve a plan that was both efficient as well as dynamic.

The project planning team played a vital role not restricting itself to simply scheduling and monitoring but working

Constructing a brand new airport in the midst of a fully functioning one had its fair share of challenges that required foresight, meticulous planning and considerable co-ordination to address and Team L&T came through with flying colors!

site and over existing facilities, an operation that Mr. Sanjay Reddy, Vice President of GVK group described as “performing an open-heart surgery on a marathon runner who was running!”

The earmarked area included ramps, car park facilities, a statue, a police station, AAI offices, a temple, and overhead tanks, apart from the apron and contact bridges on the airside. To facilitate a smooth transition, L&T and MIAL developed and implemented a master phasing plan for the New Integrated Terminal 2. Firstly, work started on the south west pier of the new terminal for which a part of the existing Terminal T2 A was dismantled. This reduced the number of operational contact stands for which the team built gate expansions through which 3 new contact stands could be added on the eastern side of the existing terminal. Next, a mezzanine floor was added to the existing International Terminals T2 B and C, to relocate the facilities from T2A. Later, the taxiway was reoriented to accommodate the south west pier of the new terminal 2.

Since a major part of Terminal 2 was to be located on the car park area apart from the Up-Down and central ramps of the existing terminal, the ramps were relocated to the extreme left and right sides. Working in tandem, MIAL created a temporary structural steel multilevel car park on the east side of the terminal.

Work then commenced on the south west side of the new integrated terminal. However, the north side housing the services hub was affected by the presence of a police station and a temple and hence a new police station and temple were built outside the airport area.

Next to be tackled were the overhead storage tanks for drinking water and fire safety facilities for the existing operational terminal and the underground sumps for the sewage facilities. The underground tanks in the newly constructed south west pier were used as interim tanks for the domestic and fire water services for the T2 B and C terminals. The entire sewage network was also diverted to the new sewage sumps constructed in the future apron area.

Due to the severe space constraint, MIAL was unable to provide land for the setup of a proper office hence the project and

client offices were located at the project site and shifted several times within the span of 6 years of construction.

Another major hurdle for the project was the relocation of the Chhatrapati Shivaji memorial on the airport premises. Situated in the heart of the building, it affected the main baggage handling system, MEP rooms, AHU rooms, fire & domestic water tanks, pump rooms and thus had to be shifted. Though a sensitive matter, it was carried out following approvals from all concerned.

The last hurdle for the Phase 2 works was connecting the south west pier with the main terminal building. This was long delayed due to continuous movement of traffic from east to west through the T2 B and C ramps until after a thorough study of the traffic along with IIT Mumbai, a reverse ramp in the eastern side was proposed which facilitated traffic to enter and exit using the same side of the existing terminal, freeing the entire western side.

With this, the Phase 2 works were taken up and completed successfully following which the facilities at the old terminal were shifted seamlessly to the new international terminal.

With the old facilities having been removed, they paved way for the overall completion of the MIAL project which

constituted the 3 buildings on the east side with 43,732 sq.m BUA, 14 fixed link bridges and the entire east side apron measuring 3.3 lakh sq.m. This mammoth task was required to shift the entire domestic facilities to the new terminal and thus making Chhatrapati Shivaji International Airport an integrated terminal catering to both international and domestic passengers.

Concept design and development of reverse ramp to enable connectivity between Phases 1 & 2

This plan was conceived following a lot of brain storming sessions led by L&T’s project planning team and stakeholders such as the MIAL project team, the airport landside operations team, the land development team, and design personnel from L&T Rambøll.

The concept design which was developed with the assistance of L&T Rambøll, was further checked and attested by IIT Bombay for the available curvature and width of the road so that it could accommodate inward and outward traffic.

Terminal traffic management

Traffic bottlenecks at a busy airport which is also a brownfield project can

easily make headlines in a city like Mumbai that is bursting at its seams. The airport witnessed massive amounts of public traffic that had to be managed alongside construction traffic bearing heavy payloads. With work proceeding simultaneously in three mega structures such as the Terminal building, multi-level car park and elevated access road, traffic management which could

have been a nightmare was efficiently managed using Traffic and Interface Management.

Validation of traffic management plan with IIT Bombay

IIT Bombay was approached to validate the traffic management plan

and propose corrective measures, if any. Surveys were conducted by the transportation department of IIT Bombay that included both video graphic and manual methods before developing a circulation plan using simulation of the entire airport traffic. The traffic data of construction vehicles provided by L&T was also added to this data to check the sufficiency of the geometrics of the existing road facilities. Based on the outcome of simulation, the geometric details were upgraded at critical sections and intersections to avoid bottlenecks during peak traffic.

Logistics management

Even before the first step had been taken in the construction of Terminal 2, a huge road block that had to be cleared was to make land available because approximately 308 acres of airport land was encroached upon by 85,000 hutments housing around 400,000 people! This was prime space absolutely necessary to establish the main offices, batching plants, material storage enclosures, offices for subcontractors and labour colonies. Faced with such

daunting circumstances, logistics management played a vital role in setting up facilities away from the project site yet bridging the gaps through meticulous planning and flawless implementation.

As the MIAL project spanned a huge area, individual sub-projects were accorded the status of separate projects and small setups were provided close to each of these operations such as the Domestic Terminal 1C, Air Traffic Control Tower, South West Pier, Terminal 2 and Multi-level car park. Even the airside works were divided into sub-projects such as the Runway 14-32, Intersection works, Delta, Domestic apron works, International Apron works, Mithi river works and the like. The sub-projects operated out of portable container offices within the project area. The canteen facility was, however, centrally located where food was prepared for the entire site team and distributed to various locations for better control on quality and cost.

L&T’s main project office which housed the top management, project leaders and other vital support services department was relocated four times to various locations to make room for upcoming structures as the project progressed. Even the MIAL office was shifted three times with the attendant shifting of connectivity and other

amenities proving to be herculean tasks.

In several cases, contracts were formulated based on the criterion of non-availability of space! Sub-contractors and vendors were encouraged to hire warehouses near the airport site for operations and storage of material. Later, even MIAL hired a common storage warehouse at Bhiwandi to minimise material storage at site for want of space.

The logistics of construction material to the New Terminal Building which is landlocked was another extremely challenging task. Meticulous traffic management and logistics planning ensured that there was no disruption of airport operations or other construction activities.

Expectedly, a huge amount of debris was generated from the construction site on a regular basis and a common disposal point was assigned for all agencies. Further, a common agency was assigned to safely dispose off the debris without harming the environment in any way.

Sequence of works

Every single package was studied in detail at the design stage itself to analyse and understand the relevant interfaces and inter dependencies. The sequence of works was finalized after several rounds

of discussions with various stake holders such as designers, subcontractors and site execution engineers. This concept, however, could not be generalized for all work fronts as it could vary according to factors. For instance, any area involving BHS was given right of preference over all other services.

Project monitoring

At the peak period of construction about 1300 engineers and 14,000 workmen were involved at the MIAL project site. This is a really huge number to monitor and control for complete alignment to a common goal and plan. To enable this, the works were divided into four groups / sprints

a) Sprint 1 – Shell & Core

b) Sprint 2 – MEP & IT works

c) Sprint 3 – Airport Systems

d) Sprint 4 – Finishes

The handover and takeover dates for each of the group was finalized and signed off between all the concerned parties and later, progress was monitored against the planned dates. The strategy for monitoring the progress was also dynamic according to the stage of the project. For instance, during the initial stages, design and manufacturing were closely monitored and later the floor team was formed to play the pivotal role of handing over the areas to the next team. When all the disciplines had completed their respective work, a strategy of ‘Focus Area’ was adopted to complete the final bit of work with the joint efforts of all concerned. This work methodology helped progress without major stoppage of work due to misunderstandings / misinterpretations.

Airside staging

At any given point of time, 24 parking stands were required for the smooth functioning of the airport. This requirement led to granular planning whereby, completed areas were handed over before taking up additional work. The fact that flight schedules are published worldwide to all the aircraft carriers through NOTAM, called for robust planning and tight monitoring.


Baggage handling system Where precision meets perfection

Passenger baggage reclaim area

Picture this. If nearly 3 billion passengers enplane every year at CSIA, one can well imagine the amount of hand and check-in baggage that has to be handled. The thought itself can be intimidating and it would be natural to imagine many thousands of hands and minds working to ensure accuracy and

The baggage handling system of the Mumbai International Airport has been designed and executed, embracing many new features and services, to make the processing of hold baggages easier, less stressful and reassuring for passengers.

precision. Surprisingly, the truth is that all this is accomplished by an efficient ‘Baggage Handling System’ (BHS) with a lean team operating and managing it. This becomes critical especially since baggage mishandling can be an expensive affair for it cost the airline industry a whopping $2.06 billion in 2012 alone!

The baggage handling system of the Mumbai International Airport has been designed and executed, embracing many new features and services, to make the processing of hold baggages easier, less stressful and reassuring for passengers.

Baggage make-up area

has provisions for future expansion to manage 10,800 bags/hour.

System planning and conceptualisation

The conceptual design of MIAL’s BHS began with the study of international and domestic flight schedules, passenger ratios, baggage profiles, dimensions, shapes and other relevant data specific to Mumbai which was supplemented with inputs and requirements from MIAL (Client) and the Airports Authority of India.

The layouts, functionalities and architecture are well-defined for the system to provide a world-class baggage facility with enhanced safety, security and service. The common check-in principle has been used to optimise the facilities allowing any airline to use any check-in counter. This centralized system is based on the Tilt Tray Sortation (TTS) technology which transports the bags from inductions to predefined destinations so that bags can be delivered from any check-in counter to any make-up carousel, giving flexibility to the airport/airline operations.

An outstanding feature of the BHS is the state-of–the art, in-line baggage

handling screening system that uses a combination of automated and manual screening processes. The departure security screening system is based on a 5 level screening concept wherein eight EDtS X-Ray machines are utilised for Level 1 screening. At Level 2A (25 workstations) & 2B (12 workstations), an operator can view the alarmed images which are diverted

for processing through Level 3 CT scan machines (4 nos.). If bags alarm at Level 3, an operator can view the images in greater detail at Level 4 (5 nos.) and all images alarming at Level 4 will be diverted onto a manual search area, Level 5 is for Explosive Trace Detection (ETD) and/or passenger reconciliation. In case any threat is identified at the Level 5 screening process, the bag will

BHS departure system layout


be diverted to the bomb cooling pit of the airport through an automated lift system and subsequently to threat bag carrying vehicles.

Design features

The foundation of this well-designed baggage system is an optimised mechanical layout, complete with the conveying lines, maintenance accesses, screening machines and processes complying to the prescribed security standards viz. International air transport association, International civil aviation organisation, Bureau of Indian civil aviation security, European security standards, Transport security, Administration, etc.

The design of the layout had been validated through computer simulations and emulations to verify the design and determine the maximum baggage processing time apart from system throughputs as defined in the specification.

The departure system is laid out declining from check-in hall at Level

4, transporting through Levels 3 and 2 to the make-up carousels in Level 1. The check-in facility has 6 islands for economy passengers with 28 counters on each island totalling to 168 counters. The 2 CIP VIP exclusive check-in facilities have 10 counters on each island. The bags are transported to the 18 make-up carousels after the security and custom screening as per the flight allocation. Majority of these conveyors are designed as suspended structures from the deck above, allowing the space below on the ground for drive-in, loading and drive-out functions.

Tilt Tray Sortation

The ‘Spine’ of the baggage handling system is the Tilt Tray Sortation (TTS) system which distributes the bags to the respective make-up carousels through the tilting mechanism. The airport features 2 sorters with 278 trays on each sorter operating at a speed of 1.9 m/s giving it a capacity to process 5400 bags/hr. The baggage from the check-in/transfer conveyor lines is supplied to two LS-4000E Tilt Tray Sorter via inductions.

The baggage is supplied one by one from the conveyor lines to the first belt on the induction where the TTS control system inducts the baggage onto an empty tray on the sorter, scans its barcode tag, transports it to the sorter and tilts it into a predefined carousel through the chute.

Control system

The ‘lifeline’ of the BHS is the control system that handles all the conveyors and sortation devices which are divided into Low Level Controls (LLC) and High Level Controls (HLC).

LLC includes all elements involved in the PLC (Program Logical Controllers) based control of the equipment such as panels, sensors, actuators, etc. All bags are virtually tracked and sorted to the designations as per the screening results by the PLCs.

HLC includes all elements of the control system above the PLCs, including networking of equipment, servers, workstations, etc. It controls the IT system of BHS which includes sort allocation controls, Message

Distribution Systems (MDS), database management systems, management information systems, baggage information systems and baggage information display systems.

BHS receives flight information, baggage source messages with real time updates and communicates the sort destination

baggage processed messages to the airport host. The HLC equipment and the LLC devices are linked via the networking edge switches located at the BHS field.

The entire BHS system monitoring, control and visualization is centralised via SCADA (Supervisory Control And Data

Acquisition). The status of individual equipment is represented in unique colours so that trained operators and maintenance employees can quickly identify and isolate the location of a fault and determine the cause within the entire system to en-force appropriate procedures.

Loads of risks to be mitigated

The criticality of BHS lies in precision. Even a single bag handled wrongly or reaching the wrong destination can create chaos. The challenges in the physical execution of baggage handling system are:

y Performance risks of the system

y Execution risks

Performance risks include the HLC development and integration, throughput compliance of the BHS layout apart from performance of the electromechanical components. These risks can be mitigated by performing repeated simulations and emulations to check the system and hardware capabilities apart from meticulous evaluation of HLC and LLC configurations through audits.

The optimised selection of special equipment such as high speed diverters, vertical sorting units, merges,

power turns, and the like assists the throughput and load balancing of the layout. This is further evaluated and ensured by analyzing simulation models for required throughput delivery and analysis on failure scenarios and requirement of redundancies. The risks associated with the performance of

electro-mechanical components such as bearings, rollers, motors, in terms of durability, energy efficiency, noise levels, wear & tear were mitigated through a selection of pre-approved makes, warranties, guarantees and factory tests.

Execution risk involves erection and interface coordination of the back-up structural steel assemblies with other terminal services such as fire protection/alarm works, air conditioning & ventilation systems and electrical & cabling works. The likelihood of clashes was mitigated through 3D model clash analysis which displays typical steel structure supports and the interfacing services. The clashes that were still identified at site were resolved by facilitating ‘on-site support’ to effect immediate changes for expediting works. The other challenge of the protection of sensitive equipment installed at site environmental conditions was mitigated through regular maintenance and sufficient protection.

Another innovative feature in the steel structure is the modular design using only clamps and screws thereby completely avoiding major work at site that will be beneficial from a long-term operational perspective for replacements and rectifications.

No stumbling with these challenges

Logistics

Escalators and travelators were delivered in heavy segments (weighing in tons) after the main façade work was completed so it took some planning and effort to bring these segments into the terminal area through the available openings.

Interiors

The interior of elevators had to be upscale to be in-sync with the ambience of the terminal. To meet the demanding quality parameters of finishes, a specialized and dedicated vendor was engaged to work exclusively on enhancing the interior look and feel of the elevators.

Installation

VHT being supply items with long lead times had to be strictly monitored even during production and dispatch of units from Spain, Germany and China. In addition to stringent factory testing prior to dispatch, experts from these countries were invited to carry out the testing and commissioning.

Vertical & horizontal transportation A notch above!

Elevators

There are 87 elevators with stops ranging from 2 to 20 landings with a handling capacity of 544 to 5000 kg and speeds varying from 0.5 to 1 m/s. A high capacity elevator is installed exclusively for moving large show pieces and automobiles into the retail area. Six scenic elevators made entirely of glass greatly enhance the ambience of the terminal.

All elevators feature speed governors and double-up as ‘Fireman Lifts’ in case of emergencies. The elevators are also connected to seismic sensors to prevent people from getting trapped inside the lift in the event of an earthquake. This apart, safety and security features include CCTV, status displays, automatic rescue device and voice announcement & monitoring through BMS.

Escalator

With a capacity to handle 9000 persons / hour, the heavy duty escalators have a rated speed of 0.5 m/s and rise-range from 3 to 11.6 m. Among the 55 escalators installed is ‘India’s tallest airport escalator’ which rises to 11.6 meters going all the way from the 6th to 10th level of the multi-level car parking (MLCP). Eight escalators are exclusively for the transportation of passengers between MLCP and the terminal building.

Travelators

Travelators a.k.a ‘moving walkways’ have been thoughtfully provided around the terminal to improve passenger mobility. MIAL features 41 of such equipment with a handling capacity of 16,200 persons / hour and a rated speed of 0.65 m/s. If installed one behind another, the travelators would measure a whopping 1.3 km in length.

The lighting changes according to time and date and manual over-rides are possible using touch screens. Mono-colour LEDs, RGB LEDs in retail, landscape and water-feature areas are grouped and controlled through DMX for dimming and creating sequences to create a vibrant atmosphere.

Lighting the art wall

A standout feature of CSIA is an impressive and expansive art wall located on the east and west sides of the T2 processor building that features themes inspired from Indian heritage presented most effectively, creatively and mystically. Each theme captures glimpses of this great country, its passage through history and what sets it on top in the pantheon of countries of the world. The art wall is lit by a wide

array of decorative and combination light fixtures.

Crowning lights

Several decorative ceiling-mounted chandeliers enhance the look, feel and aesthetics of the circulation area that have been custom designed like flower petals to resemble the CSIA logo. The diffusers are made of Borosilicate float glass in amber colour.

There are 943 such chandeliers that crown Terminal 2. Weighing between 65 to 75 kg depending on the type, these are supported by suspension tubes, which are connected to the substructure of the false ceiling such that the mounting height varies between 2.6 to 3.5 meter from the finished floor level. They are also integrated with LCMS to remotely control the lamps and monitor status.

Operating an airport is like managing a small city with numerous amenities, facilities and systems that need to work seamlessly to enable its smooth functioning. Modern day airports depend heavily on Information Technology to simplify complexities and improve efficiencies.

Interior view of Airport Operations Control Center

IT devices located throughout the facility to equipment located in Telecommunication Closets (TCs), core network switches and servers located in Main Computer Room/s (MCR/s) and IT switch rooms. Devices and systems were interconnected using standard CAT 6 UTP cables which were in turn connected onto the network through access switch ports. Redundancy was provided for across levels for smooth operation using a three tier architecture comprising core distribution, access switches and a built-in capability to allow for future expansions.

The IT network utilises the Juniper network equipment and a 3-tier carrier grade (scalable, converged for voice and data support) secured dual redundant data centre. The network is on a ‘10 Gig’ backbone that is designed to avoid downtime in case of a failure of a link, switch or any other component. A redundant fibre backbone interconnects the TCs and MCR (Master Control Centre)

accommodating servers for the entire airport systems.

The magnitude of the installation task is in the numbers: 2000 km of CAT 6 (UTP) cabling, 250 km of fibre cabling, 500 access switches, 18 distribution switches, 2 core switches, internet and internal firewalls, server aggregation switches, server farm switches and other security devices.

Airport security

Security is one of the most challenging of airport operations. A versatile and robust CCTV system takes care of wide-spread surveillance across the terminal covering all public areas including back of house operations, multilevel car park, elevated road and the ATC. The CCTV system consists of PTZ cameras, IP fixed dome cameras and IP fixed cameras connected to the IP network with video and network storage recorders. The access control system is designed to restrict access at all interface points for staff and

security, airlines and other back of house operational personnel at the piers and international & domestic operations.

The flight information display system informs passengers across the terminal at check-in desks, departure & arrival lounges and is integrated with the airport operational database. The public address systems deliver clear intelligible speech and voice alarms to various zones across the terminal in addition to automated and manual announcements.

Airport Operation Control Centre (AOCC)

The AOCC is located in the heart of the terminal and is the main command and control facility controlling the 24 x 7 operation of the CSIA Terminal at both landside and airside.

IMB receives real time updates like on-block, off-block, chute updates, first bag, last bag, baggage statistics, check-in counter updates from BHS, FIDS and VDGS and sends this information to AODB.

Extensive testing was done in the Integrated Test Facility (ITF) as well as in the actual production environment, for flawless integration.

HVAC package A warm welcome to a cool ambience

Cozy interiors that give a soothing experience

Thanks to a well-designed HVAC package, passengers are greeted by a comfortable ambience of 23°C±1°C and RH in comfort zone at the Mumbai T2 Terminal and a suitable atmosphere for the trouble free operation of critical equipment and gadgets. The occupancy and fresh air loads are based on National Building Code (NBC) - 2005 recommendations.

Design Criteria

The terminal area was divided into

100% treated fresh air units supplying treated fresh air to tenant spaces such as retail, duty free shops, restaurants, eateries and CIP/VIP lounges within that zone.

Life safety systems such as smoke extract systems and lift / stairwell processor pressurization systems are based on the respective NFPA codes. The smoke extract systems for public areas include smoke extract fans designed for high temperatures (300°C) and fire rated ducts.

several zones based on various factors, requirements and functions and then accorded weightage based on their functions such as IT, critical services, passenger and retail zones.

The terminal building had 13 zones with each one having a mechanical room that housed the Air Handling Units (AHUs) and the heat recovery units for that particular zone. The heat recovery unit consisted of enthalpy wheel and supply / extracts fans with filters. Some mechanical rooms had

If passengers are greeted by a comfortable ambience of 23°C±1°C and RH in comfort zone at the Mumbai T2 Terminal it is thanks to the well-designed HVAC package.


Detailed Engineering and Installation535 drawings were painstakingly prepared and meticulously checked in ‘3D Naviss Works’ for clash detection prior to releasing it for site execution. For clash resolution, 3D Revit software was used as it required coordination with multiple utility services. The terminal area was divided into buildings and levels to enable better control on

installation. Pipes of about 25 km and over 300 rmt ducting from AHUs were distributed in the building spread over a very large area.

Chilled Water System

The utility room located 1.5 km from T2, pumps 5800 cu.m/hr of water to the terminal through a 1.1 m diameter, pre-insulated underground pipe located below the existing roads. It was essential

that each pipe joint was 100% leak proof as rectification of joint failures would be extremely difficult once commissioned. Extensive radiography tests were conducted prior to hydraulic testing to ensure zero leakage.

air fans in the higher levels. The AHUs are located in the basement area for easy maintenance apart from keeping servicing personnel away from visitor zones to ensure passenger safety. Medium pressure ducting carries dehumidified air from AHUs to conditioned spaces while filters with activated carbon and alumina impregnated with KMnO4 (Potassium Permanganate) are used to combat the effect of exhaust fumes from aircraft that could be present in the fresh air. On the upstream side, pre-filters and back filters have been provided.

Water Flushing and Commissioning

To achieve the desired chiller performance and maintain low power consumption of chillers, it was essential to meet the required water parameters before circulation through chillers and AHU coils. Being a large system, the

water became very dirty on the first fill following installation. About 35 lakh liters of water was used to flush and remove sediments before the final commissioning.

Energy Savings

An airport never sleeps. To operate it 24 x 7, the annual power consumption of the HVAC system alone could run into several millions which is unaffordable. The answer lay in energy conservation at all times through chillers of very low power consumption and high efficiency pumps. The thickness of insulation was also carefully selected to maintain low temperature drop from utility to building distribution. For all to breathe easy considering the high occupancy rates, the building required 14 Lakh cu.m/hr of fresh air which was met by treating exhaust air through heat recovery units to lower the intake of fresh air load

on the HVAC system. The controlled fresh air is then supplied through the CO2 sensors.

The condensate recovery system was commissioned by pumping low temperature condensate generated from AHUs back to the cooling towers to reduce the cooling tower inlet temperature and thereby the power consumption apart from providing savings in the make-up water consumption of cooling tower. Cooling tower fan motors are operated through Variable Frequency Drives (VFDs) for energy savings at part loads.

Building Automation System (BAS)

Yet another unique feature of Terminal T2 is BAS with 936 (473 DDCs + 463 VAV converters) controllers and over 3300 sensors installed for the HVAC equipment alone. This system has been integrated with the Building

The Fire Protection System at T2 employs over 50,000 sprinklers connected with 270 km pipe and 500 hydrants. Rooms containing computing systems have been installed with gas suppression system that uses eco-friendly NOVEC -1230 gas.

Risk mitigation at all levels and types are of paramount importance in public buildings such as airports. Large capital is invested for the safe and secure operations of a terminal building and fire detection and protection system is significant among them.

y First aid fire extinguishers: 3500 nos installed for first level of protection

y Fire water pumping system : 6 pumps connected to 470 cu.m underground fire water tank

Integration

Integration of the Fire Alarm System is a critical part of the testing and commissioning activity. The complete

terminal building was divided into 350 fire zones as per the fire strategy and all important electromechanical and IT services such as HVAC, access doors, public announcement system, baggage handling system and vertical & horizontal transport system were integrated to meet the requirements of this fire strategy and evacuation plans. A comprehensive cause and effect matrix was also developed to identify the operational mode of the electromechanical and IT systems falling in the respective fire zones in case of fire alarm activation.

The fire alarm panel provides signal to various systems such as air handling units, fire dampers, fans, fire shutters of BHS, travelators, escalators, elevators, access controlled doors and public announcement system

to automatically operate as per the cause and effect matrix.

Never dampened to meet challenges

The biggest challenge was to create a system with global benchmarking while having to interface with various other services of the terminal. Testing & Commissioning of Fire Protection System on finish works such as false ceilings, wall claddings and carpeting was difficult that called for close monitoring. Several advanced pneumatic and leakage tests were carried out for gas based fire suppression systems during the testing and commissioning stage to ensure safety.

Public health engineering Solving watery issues

Meeting the water demands of an airport terminal is crucial that can allow no lapses. The PHE package at MIAL had its own share of complications primarily due the major quantities involved in the scope and due to the large number of vendors being involved for the supply of numerous construction material.

Even the orders for the PHE package came through in a staggered manner throwing planning and implementation out of gear several times over during the course of the project.

The Brihanmumbai Muncipal Corporation supplies domestic water to the terminal while water for flushing is catered to by treated grey water. The internal drainage system is single stack with hubless CI piping and individual venting arrangements. Planning and implementing the drainage gravity flow piping was truly a challenge due to clashes of various other services.

Another striking feature is that all the wash rooms have been provided with pipe chases featuring exposed piping

systems. The water input to this system undergoes a series of treatments including screen, CASS basin, pressure sand filter, UF, RO and finally the treated water is discharged for utilization to cooling towers, flushing purposes, gardening and landscaping.

to avoid wall chasing and for easy maintenance. Rainwater is efficiently harvested across the entire terminal as a green measure and adequate storm water piping drains off the runoff water while manholes at all accessible locations ensure easy maintenance. Several pumping systems of the existing terminal have been refurbished and put to use at the new terminal as a cost saving initiative.

Floor management Stitching it together

View of the expansive check-in area

The construction of the Mumbai International Airport was very much like solving a huge engineering jigsaw puzzle. It involved several teams working feverishly in tandem at the same location demanding insightful management for targets to be achieved as per schedule or even earlier. Project management had the unenviable task of coordinating between 5 structural

Coordination between multiple agencies was thus effectively streamlined and processes were set-up to manage

systems, 11 MEP systems and over 20 interior packages, all working with each other requiring a staggering amount of multi-stage clearances. A multi-functional core team popularly known as the ‘Floor Team’ took on the onus of ensuring that everything went like clockwork. Issue resolutions, interface management and subcontract interactions were all handled by the

disputes, mismatches and site clashes. A floor manager was akin to a project manager for the floor and some of the critical tasks handled by him included:

y Manage and document front clearances

y Interface point among various stakeholders

¾ Design

¾ Procurement

¾ HSE/QA-QC

¾ Package teams

¾ Clients

¾ Subcontractors

y Sequencing, monitoring and de-bottle necking of works in line with schedule

y Ensuring HSE, protection and housekeeping on the floor

y Issue resolution, particularly multidisciplinary problems

y Floor logistics

Floor management expeditiously resolved over 2000 clashes and coordinated the contractual closure of additional items which were critical for the completion of the

project. The functioning involved cordial meetings and joint decisions that kept the client happy at all times. A systematic problem solving methodology was followed that involved weekly log implementation, interface with design and weekly

key issue resolution meetings with clients. Other responsibilities included efficient management of the floor area, creating better working conditions, maintaining workmen discipline and creating a common resource pool comprising access devices and the like.


Testing, commissioning & trials The final sign-off

Cable net wall

Immigration counters

For the final act of a safe and orderly handing over of the MIAL project, testing was the crucial last stage. Commissioning of the airport involves networking with innumerable entities such as the client, consultants, architects and vendors to understand every single technical requirement of the project in detail.

Equipment testing was conducted during manufacturing and factory acceptance tests whereas project site and pre-commissioning tests were done on-site.

Individual system tests included commissioning and performance tests. Commissioning were tests focused on additional levels of complexity and

The Master Testing Plan (MTP) for the project was in accordance to the conditions of the Main Contract (MCoC) which L&T had entered into with MIAL. The main work breakdown for Testing and Commissioning (T&C) was made as per the requirements of the MCoC and was divided into four major stages following a bottom-top approach.

Testing was a crucial stage that preceded the safe and orderly handing over of the MIAL project. The process of testing the specified and quantifiable characteristics of an equipment/system guarantees its operability and for the airport, it was in terms of performance, reliability, safety and traceability apart from ensuring compliance to the design intent and specifications.

interoperability between equipment groups and inter-connecting components. Performance tests ensured load, capacity, throughput, utilization, stress testing, fail over tests, emergency, contingency, equipment recovery behavior and backed-up data (re)configuration tests, including any data network related components.

Integration testing which confirms functionality across systems were conducted in two stages: firstly at the integration test facility and then at the site. The tests were conducted in a controlled test facility. The systems were connected through a mock-up of the network communications to mitigate risks at an early stage with a strong focus on software / firmware functionality of different systems.

Scope of T&C y 35 systems under the scope of L&T

y 21 systems by MIAL

y 68 interface via dedicated cabling

y 110 interface via shared IT network

y 08 interface via IT shared network through IB

y 835 string testing

y 5 group testing

y 55 scenario testing

Considering the size of this project and involvement of different facilities such as utility building housing the multi receiving substation, HVAC chillers, sewage treatment plant; NACIL building, air traffic tower, Terminal 1C where the master computer room 1 is located, it was necessary to have a master interface diagram, a master system interface list and sequence of commissioning for different systems.

The terminal was divided into twelve different blocks identifying the coverage area of different systems and a sequence was developed to have a seamless T&C with proper monitoring

Major responsibilities of T&C team

y Develop guidelines and templates for testing, commissioning, training, project operation trials, operation and maintenance manuals

y Review and validation of test procedures as per the technical specifications, interface control documents

y Identification and incorporation of special requirements of OMDA, specific standards like NFPA, ASHRAE, NEC, and client requirements

y Sequencing, phasing and monitoring the T&C activities of all systems

y Coordination for project operation trials

y Develop sequence of T&C activities between facilities and readiness for project operation trials to commence

y Master system interface matrix as per different PTS and ICD

y Commission sequence for different systems

y Integrate testing sequence for different interfaces

y Develop integrated T&C schedule

Testing, commissioning and integration of multiple airport systems needed special skills and the ability to communicate effectively to define and redefine every single requirement so as to advance the stage of static installation with respect to prescribed requirements.

Project Operation Trials

Integration Tests

Individual System Tests

Equipment Tests


Commissioning and Integration testing of more than 56 systems with 186 interfaces involving different people required considerable projection and planning. Continuous interaction with all participants and keeping them abreast of the developments through timely communication and exchange of information helped mitigate this issue.

T&C workshops and meetings were regularly conducted with the prime objective of facilitating agreements with all sub-contractors regarding roles and responsibilities, timely provision of interface information and identification of critical issues.

Challenges y The most important challenge for

L&T as the main contractor was to play the role of Master System Integrator (MSI) as the scope of the System Integrator (SI) was limited only to Information Broker (IB) centered systems

y Identifying the different types of interfaces and making a particular

subcontractor responsible as system initiator for a group of interface

y To conceptualize the entire business model of the functions of the airport and develop the integrated T&C sequences

y Review, coordinate, monitor, witness of specific requirements during the execution of integration testing

Project operation trials

Project operation trials conform to airport processes and standard operating procedures and have a strong human element focus, predicated on the integration and inter-operability of systems and facilities.

In airport operations, passenger and baggage are prime considerations and hence there were baggage and terminal trials which involved core, support, contingency and emergency processes.

The baggage trials involved different stakeholders like the airlines, airport operations, airport maintenance,

customs, and security team to familiarize themselves to the systems and facilities.

Terminal trials started in May 2013 with single process trials where the focus was on a single process like terminal entry, trolley movement, check-in, staff entry, delivery of goods and waste management. Once the single process trials were completed successfully, integrated trials started where different processes were simulated in an integrated manner like departure trial involving the check-in process, security screening, immigration and boarding. Integrated trials were conducted in non PPE environment involving different stakeholders such as airlines, customs, immigration and CISF. Contingency trials were also conducted for different types of failures like power; network and emergency. During the advance trails the entire facility including multi-level car parking, elevated road network was done with 2000 trial volunteers (trial passengers).

Airside works Soaring above the superlative

Bird’s eye view of the airside

The planning and phasing required relentless coordination between design, engineering, procurement, purchasing, and project controls with granular attention to detail. The initial projects falling under the airside works, such as apron L, 14 loop, 32 loop, taxiway D stages 1 & 2 and the central loop were aimed at enhancing the infrastructure and airport efficiency. These projects were taken up in the early phase so that

the major part of the runway upgrade projects could be delivered on time.

Planning and phasing of airfield works: were divided into ‘Seasons’ with one season defined as the working duration from 1st October to 31st May of a particular year.

Season 2008-09: During this season, the projects executed included the delta

taxiway stage 1 & 2, apron H, central loop, 14 end loop, 32 loop and T1C apron, selected for multiple work front creation and improving the efficiency of the runway.

Season 2009-10: Projects taken up and completed were the runway 14/32 up-gradation, runway intersection works, T2 apron, delta taxiway stage 3 to 6 and runway 09 west end.

The journey towards creating a world-class airport at Mumbai started in mid 2007. The challenge was to strike a balance between undertaking a complex construction project whilst maintaining operations in one of India’s busiest airports. Being a brownfield project, it was absolutely necessary to envisage the complexities involved in executing airside works without disturbing operations.

Season 10-11: The projects handled included the runway 09/27 up-gradation, T2 apron, delta taxiway stage 7 to 9 and Mithi River phase 1.

Season 11-12: The Mithi River phase 2, Mithi River bridge strengthening work, taxiway N1, taxiway E3, taxiway N1-N3 junction, engine run-up bay and T2 apron were handled.

14/32 runway and intersection works

The 14/32 runway being the secondary runway was taken up early in the piece for renovation. It was closed for 6 months during the ’09-’10 season for major rehabilitation, including pavement strengthening and widening, slope compliance correction, drainage upgrades, AGL upgrades and construction of new connecting taxiways. One of the major complexities in this was the intersection works of the 09/27 and 14/32 runways. Work was permitted only for 6 hours every Tuesday during which time the airport was completely shut down. The work proceeded rapidly on the intersection for 22 weeks and, as expected from L&T, was completed as scheduled!

09/27 runway runs to completion

Re-carpeting the 3.4 kms long 09/27 main runway involved 1.45 lakh t of asphalt, 59 km of AGL conduiting, 3.3 lakh sq.m of grading, 2.6 km

of drains and 12 km of duct bank along the runway. Work was carried out largely during the restricted hours from 09:00 a.m. to 5:00 p.m. every day for six days a week. To ensure that the runway was handed over in a ‘ready for operations’ condition. Meticulous planning and

coordination among all stakeholders were imperatives on a daily basis. Post construction, runway 09/27 now boasts off the capacity to handle wide-bodied ‘Code F’ aircrafts such as A 380 and B 747-8.

Working without sufficient elbow-room

Space was always a constraint especially for apron development around Terminal 2 at CSIA for

maintaining the existing aircraft parking positions, taxiways, service roads, cargo staging areas and GSE parking.

At every stage of apron development, only a limited number of aircraft and equipment could be shuffled from one place to another. With such moves being typically restricted to 1-3 aircrafts at a time (a single aircraft stand measures around 5,000-10,000 sq.m), developing an apron of approximately 9 lakh sq.m currently occupying over 30 aircrafts, was a herculean task that involved several stages of micro-phasing development and meticulous implementation.

Bridge over River Mithi

As part of Maharashtra Government’s initiative to upgrade and expand urban drainage systems following the devastating 2005 Mumbai floods, the existing Mithi River flowing within the vicinity of CSIA was widened significantly. The part of the river that runs beneath runway 09/27 and parallel taxiway N1 also had to be

widened which required closure of the taxiway and shortening of the runway for 15 months to combat which an enormous 2 x 12 m cast in-situ bridge culvert was constructed across the airport to almost double the capacity of the river.

Overcoming multiple challenges

Though Team L&T achieved resounding success in the task of airfield works, it was not without encountering multiple challenges such as:

y The existing airport site is land locked by the surrounding city, complicating logistics planning

y Construction in an operational environment, on top of the existing pavements that are being used daily for aircraft operations and parking had its own complexities

y The Mithi River diversion was a complex job. Since the actual quantity of hard rock encountered

was 600% more than the predicted estimate, 25 rock breakers were deployed all along the location for completing the job on time

y Time restrictions for operations were major challenges

y Frequent disruptions to work due to VIP visits

y The Mumbai climate which can potentially shutdown all works during the monsoon period lasted almost 4 months

y Non-availability of existing underground service layouts

Despite the inherent challenges, the project team successfully completed approximately 24 lakh cu.m of earth work, 8 lakh cu.m of concreting and 4 lakh t of asphalt - a truly amazing feat considering that it was accomplished without any disruptions to a fully functional airport.

Going green

To make the project more economical

and environmental friendly, the project team adopted rubblization and concrete recycling technologies in the T2 apron development works. The existing concrete was either rubblized in-situ or crushed on-site and recycled for reuse as base-course material by using specialist machineries imported from Europe. The base material underneath the existing apron pavement was also recycled. Apart from material being reused, these initiatives also saved a great deal of transportation requirement and thereby reduced the use of fossil fuel.

Many reasons for L&T to take a bow!

y L&T took up the critical work of main runway up-gradation involving restricted timelines from 09 a.m. to 05 pm with complete confidence and experience gained from past projects. The project was handed over for air traffic from 05 p.m. to 09 a.m the following day. Despite this short time period and criticality

of working on a functional runway, the project was handed over one day ahead of schedule.

y An invisible blast fence was procured and installed for the first time in India

y Strengthening of existing Mithi River bridge under operating main runway carriage way was executed before schedule to accommodate A 380 (Code F) aircraft

y E3 Taxiway was constructed in a restricted time during 14/32 runway closure from 10th October 2011 to 12th January 2012 and was handed over 8 days ahead of schedule

y N5 taxiway was constructed during the restricted time period of main runway shutdown for six hours from 20th January 2012 to 20th May 2012. It was completed 10 days ahead of schedule

y Installation of zero radar footprint, invisible blast fence made of fibre glass for the very first time in India

Forecourt and elevated corridor Flying in to the airport forecourt

Mumbai is perhaps the only metro in India to boast off an airport located right in the heart of the city. Though well connected to the arterial ‘Western Express Highway’, reaching it can be quite harrowing. To address this vexing traffic issue, a dedicated elevated corridor leading to an expansive forecourt was proposed as a part of the MIAL project.

The MIAL elevated corridor features some of the best-in-class technology making it a landmark in its own right. There are 81 spans of cast in-situ spine connected to a precast cantilever with void former of 2200 mm diameter, a first-of-its-kind structure in the country. Another unique aspect is that it contains various types of superstructures comprising of in-situ PSC & RCC voided slabs, PSC & RCC box apart from ‘I’ girder spans. While the superstructure is varied in dimension, the cantilever section was precast and erected using specially designed launching girders.

The centre spine was constructed using conventional cast-in-situ methods with massive staging works whereas the cantilever portion was precast and connected to the main spine using state-of-the-art stitch concreting and post tensioned cables. This four lane access way connects MMRDA’s Sahar elevated portion to the airport’s forecourt with a deck width of 19.2 m that expands to a whopping 73 m (9 lanes along with wide footpaths in front of departure) as it approaches the terminal departure bay. A couple of two lane ramps enable ascent and descent from the departure level leading to Powai and Sakinaka parts of Mumbai. Three connecting ramps at an elevated level of 16 m connect the MMRDA portion and level 10 of the multi-level car park. Tree-lined, the deck of the superstructure features attractive palm trees and shrubs in the median apart from aesthetic lighting that adds to the grandeur.

ATC sky tower

The new Air Traffic Control Tower at Mumbai’s Chhatrapati Shivaji International Airport stands tall as an iconic representative of the meteoric rise of the Indian aviation Industry and its entry into global reckoning. The nerve center of one of the busiest airports in the world, the ATC tower, with its futuristic design, rises to a height of 83.8 meters, the tallest of its kind in the country and unique in its placement being located outside the airport premises, in the forecourt of the domestic terminal.

Conceptually designed by the Hong Kong-based global architectural firm, HOK, the tower will be the first sighting for travellers coming into CSIA as it is taller than the existing ATC. Its view will extend beyond by 5 miles from each of the runway’s start and end points.

Features

Built in a site area of 1200 sq.m, the tower consists of 3 floors at its base called the technical block for security and Airport Authority of India (AAI) staff for ATC operation. There are 4 floors at the top called the ‘Stalk and CAB’ that accommodates the ATC operational area, navigation equipment, etc. The rest

Rising above to lord over all it surveys, the new ATC Sky Tower at Mumbai’s International airport stands as a towering example of L&T’s prowess and considerable capabilities.

Multi-level car park The most spacious pit-stop in town

The 10 floor MLCP has a 5000 car and 400 two wheeler capacity and can be accessed from both the elevated and at-grade road levels. Built on a 2.32 lakh sq.m area, it connects to every level of the terminal via 8 elevators and 8 escalators for hassle-free movement. The MLCP is also stacked with adequate trolleys for baggage handling and wheelchairs for the differently abled.

Gardens and water fountains give a relaxing and soothing experience to the passengers. About 20000 sq.m of beautiful landscaping makes it one of the most exquisite parking facilities in the country. The architectural finishes include 1.5 million sq.ft of painting, 95000 sq.m of floor-decking work and 20000 sq.m of external granite flooring.

The HVAC system includes 3324 fans for ventilation and the entire building features a world-class fire detection and protection system apart from CCTV surveillance and public announcement systems for enhanced safety of passengers.

The Multi-level Car Parking (MLCP) at MIAL could easily be India’s largest at an airport packed with some of the most passenger-friendly conveniences.

Construction methodology

The ATC sky tower is unique in its design, construction, erection and functional performance. It stands tall from FGL on 11 pile caps of which the central cap supports the central core wall which extends up to +77.80 m (level 0 to level 22) and an inclined skirt wall which connects to the central core at +62.05 m (level 0 to level 18). Passenger and firemen elevators are provided inside the core with a staircase through the core from level 0 to level 22.

The 1st lift core wall (3 m) was executed using conventional formwork while further lifts were executed using climbing formwork. The technical block floors followed after the core and skirt wall completion up to level-4. The skirt wall ascends right up to 3 lifts below the core wall and the staircase inside the core ascends 3 lifts below the core wall using conventional formwork. Concreting was done using pipe line.

The skirt wall is connected to the central core at + 62.05 m (level-18). After the connection of core and skirt, the preparatory slab was taken up for erection. During the same time the core continued leaving the beam embedment at the respective cab level slabs. After erection of the preparatory slab, the structural steel beams along with rolla-deck sheets and rebar was fixed in position for level-18 to 20 and concreted.

Accuracy in profile was achieved by shuttering that involved pre-check and post concrete check surveys. The skirt and core walls were constructed using the jump formwork system. Formwork fixing for concrete and installation of façade glass panels was monitored through an anemometer for wind velocity. The structure has an external coat of anti-fungal, dust resistant, and anti-carbonation paint which involved a critical procedure of heavy staging around the structure and sequential painting from top to bottom.

These tests also took into consideration the structural design intent in terms of durability and seismic conditions. About 28000 tons of structural steel and 30000 tons of reinforcement steel were tested.

inspections and test plans were prepared and implemented during project execution. A material approval system was introduced and over 350 materials were approved in the contractors’ works package. An exclusive system for material approval of sub-contractor works package was also implemented by taking approval from designers and architects from both the L&T and the MIAL teams. So tight was the material approval system that due approvals

For a project of the size and complexity of MIAL, it was imperative to set project specific quality objectives with regard to monitoring, auditing and reviewing so as to exceed the expectations of the client, in specific, and visitors to the airport, in general.


Attractive ceiling made of Glass Fibre Reinforced Concrete

The project involved huge volumes under different disciplines which went through stage-wise process inspections such as on-site and off-site inspections for material and process controlling. Numerous tests were carried out in the well-equipped, on-site labs.

For stringent process control, several inspections were performed including; material on receipt, pre-dispatch and factory inspections. Stage-wise inspections were also conducted for every activity to maintain the exacting standards in conformance to the L&T stamp of excellence.

Management review

Management review meetings were conducted bi-monthly to assess the progress on quality objectives and to formulate action plans to achieve the set objectives. Action plans included product quality ratings, acting on customer complaints, corrective & preventive action on audits and implementation of the same. Non-conformance reports issued by the client were reviewed on a periodic basis to focus on avoiding repetitive complaints and identifying critical areas for timely action.

Due to the large scale of operations, establishing certain facilities enabled L&T to carry out construction in a hassle free manner and achieve the desired quality standards.

Steel Service Center (SSC)

SSC was commissioned for better control and management of huge volumes of reinforcement steel in terms of minimal wastage, better inventory control, enhanced quality apart from on-time and on-schedule delivery

Concrete batching plant

The establishment of a concrete batching plant at the site not only produced economical concrete but also facilitated rapid supply to site locations for achieving progress under the control of QC inspectors round the clock.

Hot mix asphalt plant

Setting up of a hot mix asphalt plant for a brownfield airport project was a critical task but it reduced the trip time of hauling vehicles especially for the runway asphalt works which were carried out in a window of 6 hours a day with assured quality.

Demolition works by hydraulic concrete crusher

Hydraulic concrete crushers with diamond wire cutting were used for demolition of old buildings. About 2500 tons of reinforcement scrap was retrieved from the reinforced concrete members such as slabs, beams and bridge decks.

Clash resolution technique of 3D modeling

Clash resolution technique was adopted for clash analysis of all mechanical, electrical, plumbing services and airport services inside the terminal building.

Green construction technology

Existing rigid pavements were rubblized by advanced machines and used for developing pavements above it. Demolished pavement materials like pavement quality concrete boulders were crushed for reuse as granular sub base for pavement works.

Pre-cast technology

Pre-cast technology was used to cast various structural elements like precast

wall panels, drains, ducts and chambers to reduce construction time and achieve the desired quality.

Light weight concrete

Light weight concrete having density equal to that of water was used to overcome extended thickness to achieve the desired slope and at the same time reduce the load on the RC structure in the multi-level car park.

Gypsum plaster

Gypsum Plaster which is more economical compared to river sand was introduced in place of conventional plaster to save on cost and overcome the quality issue due to silt.

Self Compacting Concrete (SCC)

SCC was used to achieve the desired architectural intent of curvature, slim and corrugated elements. Consistency in surface texture of the ATC sky tower profile stands a tall testimony to this path-breaking technique.

Quick-set concrete

To overcome time constraints during runway overlay works, quick set concrete was used for encasing ducts and pipes so as to allow usage of the runway within 6 hours from the commencement of work.

Milling of asphaltic pavement

Milled asphalt material was used as a substitute to granular sub-base in minor pavements and shoulders, thus reducing cost and consumption of material.

Foundation of quality

The foundation engineering for the terminal building and the ATC tower comprised bored cast in-situ pile foundation. Over 5000 piles of different diameters and 5000 rock anchors were installed and its application in the foundation was monitored to ascertain the designed load to competent sub-strata through various load tests such as vertical load tests, lateral load tests, instrumented cyclic load tests, pull out tests and integrity tests. The strata for

bored piles were completely verified and inspected by deploying a full-time geo-technical engineer along with a QC engineer.

The investigation of raft subsoil of Terminal 2 was carried out to determine the general sub surface conditions and grout underneath the basement surface using ground penetration radar survey which is an electromagnetic geophysical method for mapping of cavity in rock anchor and the grout vicinity.

Best practices

CONQUAS

CONQUAS technique was implemented to ascertain product quality rating for all components of works and take up preventive measures required to improve product quality.

Visual communication

Do’s and Don’ts for concrete works, finishing works and MEP works were displayed at appropriate site locations,

tough task that becomes increasingly tougher when the stones are sourced from various locations across the globe. To avoid shade variations and to ensure avoidance of unsuitable shades in the stone works, it was decided to proceed with dry lay of stone before the final wet lay. Architects from L&T & MIAL were involved in identifying the right shades of stones to avoid the use of unsuitable stones with different shades. This exercise was done in addition to source inspection.

Protection of works

Protecting the final finished product inside a terminal building where several other activities were proceeding in tandem was important. For instance, protecting the granite flooring and glazing from breakage or scratches was very difficult. Replacing the damages involved cost, time and other complications since most of such materials were imported. Special protective measures were adopted such as covering the stone works with commercial plywood and wrapping breakable materials like glass with cardboard sheets.

Contracts management Focusing on the finer elements

Work in progress at the bull nose and elevated road network

The contracts management team comprised a clutch of expert talent with world-class specialization to guide and support a young and dynamic mainstream staff team. Backed by the benefit of steep learning curves from three other mega airport construction project contracts at Hyderabad, Bangalore and Delhi, the team formulated experience-based

The lofty aspirations of the client (GVK) to create a world-class airport saw the project team relying on the capabilities of several third party organizations that had no prior presence in India. This considerably increased the need for a robust and efficient risk management strategy.

The strategy of the contracts management team was focused on creating a better

strategies with foresight considering future risks.

However, the MIAL project had certain unique characteristics rendering contracts management, in general, and risk management, in particular, incredibly challenging. The fact that this brownfield project was located in the middle of one of India’s most densely populated areas was a major challenge.

The strategy of contracts management was focused on creating a better understanding of the contract obligations and its implementation at every level of staff involved in the project.


understanding of contract obligations and its implementation at every level of staff involved in the project. In the course of conforming to the obligations of the contracts, care was taken to ensure achievement of cost benefits and customer satisfaction.

Playing the IT advantage

The implementation of contracts relied heavily on the latest innovations in information technology. A case in point being the Electronic Data Management System to deal with the challenges of handling time bound, massive quantum of communications with various stakeholders of the project. This system was inspired by the ACONEX system adopted in the Delhi International Airport Project and based on that experience, a new system was developed and implemented by the in-house team in a cost effective and successful manner.

Every single document had to pass through a contractual screening for verification. Taking into account the

critical contractual response time of the communications with the involvement of various stakeholders, a communication protocol was evolved and strictly adhered to.

Spreading the word

The awareness on contracts was a key to the successful implementation of the project. Team leaders made every single individual involved in the team aware of the contracts by conducting training sessions, monthly meetings and circulation of contractual obligations and highlights. The various tools of contracts management such as claim management, subcontract management, change management and payment management were strategically handled within the established protocols with the client as well as subcontractors. The perennial issues involved in a mega project such as coordination, access, payment strategies were based strongly on earlier experiences.

In the case of the Mumbai International Airport, it was evident to the contracts

management team that a complex brownfield project always had the possibility of increasing the variables in the risk management equation. To mitigate it and handle risk management successfully, the team had to be versatile and constantly sought added information to mitigate risks.

Plugging the brain-drain

The learning that the team acquired from the project is an invaluable resource that had to be carefully documented and archived for future use. The contracts team ensured that specifications, method statements and learning on successes & failures were all recorded for every discipline in a single repository. The sharing of such experiences not only ensures development of a holistic, project-wide understanding and improves interdisciplinary efficiency but also helps immensely for future tender proposals and project implementation.

Site administration Enabling the enablers

In the case of MIAL, the challenge for the admin team was to provide suitable and comfortable accommodation for all the staff members who were trans-located from various parts of the country and, perhaps, the world. This involved a staggering 450 families and about 350 bachelors.

The task was huge: to find suitable residential complexes for such large number of staff members, near the site, in heart of Mumbai city complete with police NOCs and society permissions.

Finally, three societies were identified and selected. At peak period, about 300 apartments were booked in Bhandup, and another 250 flats in Malad to accommodate all the staff members while 25 flats in Powai were earmarked exclusively for senior staff members. Locations were carefully chosen having all amenities and facilities such as schools, hospitals and entertainment in the immediate vicinity.

Once the people were placed, the next big challenge was to arrange for their movement between residence and project site in the bustling city of Mumbai. About 21 buses and 100 cars ensured that people were able to commute conveniently. The catering for the bachelor staff members at all the facilities was also ensured right from the early stages.

In a project of this magnitude and complexity, the employees were always under pressure both to perform and complete the project on time. Several get-togethers and sightseeing trips were organized for them and their families to stress bust and enliven their spirits. Some of them even involved themselves in a few CSR initiatives to give something back to society despite their busy schedules.

An administration team’s work kicks-off way before even the mobilization process begins for a project.

Plant and machinery Resources – propelling productivity

Planning resources such as man & machinery were unique for MIAL due to the sheer volumes and the high fluctuations in requirements due to staggered receipt and packaging of jobs. It was therefore the responsibility of a specially formed central resource planning team to mobilize, deploy and demobilize all critical resources such as batching plants, steel service centre, formwork, plant & machinery apart from workmen and staff with the twin objectives of optimum utilisation of resources at levels and avoidance of any compromise in the progress of the project.

Formwork

Handling 7600 tons of formwork material and reconciling such huge stock periodically is humanly impossible, if attempted manually. A dedicated software was developed for this which also avoided duplication during manual counting. Item-specific 2-D bar-coded stickers were developed and used on the formwork material for faultless inventory management.

Steel service centre

Since huge volumes of rebar had to be cut and customised for concreting, a sophisticated steel service centre with 3000 t per month capacity was established right at the early stages of the project that helped automate rebar works. Wastage was substantially reduced by using bar bending schedules (BBSs) with RC CAD software and other special software to optimize the cutting schedule. The cut rebar were organised

and labelled in detail to ensure easy identification at site.

Plant and machinery

Plant and Machinery (P&M) was the engine that powered the project. The

right machine was made available based on the construction methodology and programme schedule which propelled the progress of work as scheduled. In several packages, the project was completed ahead of schedule due to the innovative deployment of P&M.

Material

Handling enormous quantity of bulk materials such as aggregates could result in erroneous quantification of the physical stock. Hence, third party survey teams were hired to ensure the accurate quantification of available physical stock.

Workmen

Terming the workforce that trudged everyday into the project as ‘an army’ would have been an understatement. The manpower exceeded 15000 during peak periods of construction. Mobilising and retaining workmen of such huge numbers across disciplines of construction was certainly a challenge that was overcome by tying-up with social organizations to source rural unskilled labour. An on-site training centre established with the help of L&T’s Construction Skills Training Institute, trained such raw workforce greatly enhancing their skill levels within short periods. Suitable workmen tenements were planned at the vicinity of the project along with management of daily commute using the dedicated services of 130 buses from Mumbai’s ‘BEST’ undertaking.

Innovations at MIAL Inspired by insight

Rubblization work in progress

Demolition by hydraulic concrete crushing machine

‘Destruction for construction’ was an oft used term in the MIAL project as several existing structures had to be demolished to make way for the newer ones. For this a 26 m ‘high reach’ boom hydraulic concrete crusher and a dust boss water spraying machine were used in combination.

was isolated from the remaining portion using ‘diamond wire cutting’ of concrete members such as slabs and beams.

y Reinforcement retrieved from the scrap alone amounted to 2500 tons of steel

y Resulted in 35 % savings in cost when compared to conventional demolition methods

y The total quantity crushed was 32,000 cu.m of which reinforced concrete alone was 16,000 cu.m

y About 13,000 cu.m of RCC ramp at a height of 23 m and about 35,000 sq.m floor area of the 20 m high terminal building was demolished.

y Only a portion of the slab and ramp that was meant to be retained

MIAL had several ‘firsts’ and numerous path breaking innovations to be proud of in the areas of construction, demolition and recycling of construction waste.

Cable net wall structure

MAIL uses a highly transparent structural glass system called the cable net wall structure that eliminates the use of conventional support structures, utilized are pre-tensioned cables arrayed in vertical or horizontal patterns. This glass wall structure gives the transparent facade

a clean and seamless look including all the capabilities of a conventional wall system. MIAL is also benchmarked for using the longest unidirectional cable net wall structure in the world, the only cable wall of its type that uses sharp corners. Three types of systems have been used, such as, building to roof, building to building and roof to roof.

Rubblization

To construct a new pavement, the old one needed to be removed and the breaking, excavation and removal of waste material would have been a massive logistical problem in the already congested airport area. The concept of recycling the existing pavement material was proposed and advanced machines were mobilized from England for rubblizing the pavement and using it as a subgrade. Roughly 75,000 truck trips were saved, thanks to rubblization, apart from saving a massive land fill of excavated material.

Strengthening the bridge over the River Mithi under the main runway

An aircraft takes off from Mumbai airport’s runway every three minutes. To withstand the impact of so many frequent take-offs and to support gigantic aircrafts (such as the Airbus A 380) that weigh close to 600 tons, the bridge over River Mithi had to be strengthened. CFRP (Carbon Fibre Reinforced Polymer) was used to

Hot tapping method

To maintain fuel supply to both the operational airport as well as the new one, the innovative Hot Tapping Method was resorted to employing the following methodology:

y A ‘Stopple’ machine was installed and plugs inserted at each of the 4

locations to ensure that the fuel flow was through the 18” bypass line only

y After draining the fuel, the redundant existing pipe section adjacent to bypass line was cut and removed. A new diverted pipeline was fixed to the existing 22” pipeline between the two cut locations

y The ‘Stopple’ plugs were first removed at two intermediate points and then at the two extreme points thereby closing the sandwich

valves to divert fuel flow only through the new pipeline

y The redundant 18” bypasses lines and 22” old main pipeline were removed after draining the leftover fuel

y Fittings were welded to the existing pipeline at four locations, while fuel was flowing at a controlled rate of flow between 5300 to 15700 litres per minute to adequately dissipate the heat of welding and avoid rapid cooling of the weld. Leakage checking was done with nitrogen purging.

Head house structural steel erection

Due to space constraints, a unique methodology was adopted for the erection of structural steel works. A 250 ton structural steel pod each of size 32m x 32m and weighing about 250 tons was erected using a launching mechanism. A highway temporary truss was used to erect the pod from the launching platform at one end to the mega columns which were 40 m free standing columns. 29 out of 30 pods in the structure were erected using this innovative methodology.

L&T completes first-of-its-kind composite slab at TCS Siruseri project in Chennai The steel - concrete composite slab at +94.125 m level of Signature Tower of TCS Siruseri project was successfully cast on 8th of January 2014. This is a first-of-its-kind achievement in L&T, in view of the height at which the composite slab was completed.

This feat was completed amidst challenges that included working at a height of +94.125 m and completing a RCC slab that was embedded with heavy structural steel. The +94.125 m level structural steel girder supports the column at its tip to support the levels above it. The structural steel girders of 1.5 m and 1.60 m depth are embedded into the 2.60 m thick RCC slab. Advanced non-linear analysis using ATENA software was done to predict the behavior of connections, modes of failure and to estimate the load factor.

The slab encompasses 14 plate girders with total weight of 120 t. The maximum weight of a single plate girder erected was 9 t at 24 m radius. Designed by EDRC, the execution was ably supported by CMPC, BSCC & EHS of HQ /CNCL among other stakeholders. No single rebar was lapped and all bars were connected by mechanical bar couplers that warranted meticulous planning of threaded bars. The reinforcement steel were heavily congested (450 kg per cu.m) posing difficulties in execution while tying.

M 40 grade, temperature controlled, SCC was batched using chilled water and crushed ice.

AR posthumously awarded Padma Bhushan

The late Dr. A Ramakrishna (AR), former President and Deputy Managing Director, was posthumously honoured with the Padma Bhushan in the category of ‘Science & Engineering’ on Republic Day 2014. It was a fitting recognition for this ‘Master Builder’ and for his wonderful contribution to the rise of L&T Construction in an association that spanned over four decades.

Speaking about the signal distinction, Group Executive Chairman, Mr. A M Naik, said: “This honour is richly deserved recognition of Dr. Ramakrishna’s accomplishments in the field of infrastructure and construction.”

L&T’s CEO and Managing Director, Mr. K. Venkataramanan described Dr. Ramakrishna as a “doyen of the construction industry” and added that the Padma Bhushan was national recognition of his expertise.

AR, who passed away on August 20th, 2013, has left an indelible mark on L&T Construction through his innovative thinking, inspirational leadership and humane disposition apart from being the moving force behind building some of the country’s most spectacular landmarks.

“A technocrat par excellence who worked his way up through technological excellence and innovative strategies, is how Mr. K V Rangaswami, Advisor to the Group Executive Chairman described AR and added that he was quintessentially “an organization builder.”

Mr. S. N. Subrahmanyan, Member of the Board & Senior Executive Vice President (Infrastructure & Construction), who had the privilege of AR’s tutelage during his formative years was more eloquent in his praise. “I am very happy to know that our beloved AR has been conferred with the Padma Bhushan Award, the most prestigious civilian award in our country. It is really a proud moment for all of us at L&T. It is indeed a most fitting tribute to one of the most outstanding civil engineer and technocrat. He has been a great mentor and boss. Under his leadership, erstwhile ECC witnessed new unprecedented peaks and diversified into many new lines of business. He was seen as a humane leader in L&T with pleasing demeanour, optimism and vision.” We, at L&T, salute the memory and the considerable accomplishments of this great champion of our Company.

The Institute of Engineers, Andhra Pradesh Chapter, Hyderabad has instituted ‘Annual Endowment Lectures’ to commemorate Dr. A. Ramakrishna’s contribution to the infrastructural development of the county at large and to Andhra Pradesh in particular.
