Entering the age of the highrise

Over the last decade we have witnessed a major construction

boom with hundreds of high-rise structures rising out of the

ground. With growing urbanisation, 50% of India’s population is

expected to live in the cities by 2030 which would result in lack of

space. This is driving the inevitable demand for more high density

tall buildings.

In India, Meinhardt has played an integral role in some of the best

skyscrapers in the metro cities of Mumbai, Kolkata, Chennai and

beyond, include one of the tallest towers in the country.

Our current portfolio in India includes South City: Kolkata’s Tallest

Tower; Albatross, Tallest Tower in Making, Chennai; Urbana I,

Upcoming Tallest Tower in Kolkata and much more.

The old adage of global reach, local delivery remains important

in this building type. We are able to harvest the knowledge and

experience of the global group to optimize schemes at the early

stages of the project guided by local offices with local expertise

and understanding.

As a group we are privileged to have worked on dozens of

skyscrapers across the globe giving us the excellent reputation we

have today in engineering this type of building.

We have assembled a specialist engineering team, armed with

engineering excellence and knowledge of the latest, cutting-edge

technology in high-rise design to deliver both practical and

imaginative skyscraper solutions.

Meinhardt has the internal resources to address any structural

challenges and deliver cost effective and efficient solutions across

a growing range of civil and structural engineering projects. Our

focus is firmly entrenched in delivering what our clients need.

In this special edition of tall buildings, we will share some of the

latest thinking in high-rise design in India, as well as internationally,

and hope you enjoy reading some of our successful engineering

stories.

Despite the global downturn, the beginning of 21st century has seen a growing trend in tall buildings in India.

‘Albatross’, located in the plush suburb of Old Mahabalipuram, is a new residential development which will soon feature Chennai’s tallest building. Comprising three towers of G+27 floors (97m) and the signature tower of G+50 floors (168m), more than 60% of the residential units have a direct view to the sea.

In the Making: Chennai’s Tallest Tower

Value EngineeringWith the signature tower, the structural positioning of the shear walls

has been crucial in order to create an earthquake resistant design

but we have also managed to create the optimum configuration

to make the structure more cost-effective for the client. Careful

consideration has been given to the stringent development control

guidelines outlined in the CMDA (Chennai Metropolitan Development

Authority), NBCI (National Building Code of India) and International

Building codes for high rise residential developments.

The project is a true collaboration with our teams in India and

Singapore working alongside SRSS Architect, Singapore. A

co-ordinated approach has delivered all drawings in the detail design

phase to schedule.

TALL BUILDINGS FEATURE

Raheja Oma creates a world class living experience in an exclusive

gated environment. The central feature is a 38 storey residential

tower, which is encircled by low-rise apartments.

The iconic 140m high tower, with 392 apartments, has a rectilinear

staggered form with floor plates progressively reducing in size

along the height with unique a tapering shape. The global outlook of

OMA is complemented by an infinity pool and skypad on the 36th

floor.

The plan geometry forms a T-shape which provides an inherently

high structural rigidity for the tower.

Value EngineeringOur team selected shear walls over columns as a more effective

earthquake resistant solution. This option also allowed us to reduce

the amount of steel needed by using more economical 6kg steel.

Through rigorous analysis we were able to save the client 10 to

15% in steel by adopting the sheer wall concept and significantly

reducing the construction costs.

We are also now analyzing foundation design options to improve

the high bearing capacity of the structure with the aim of saving a

further 10% of steel.

RosedaleKolkata, West Bengal

Rosedale: Leading High-RiseThe Rosedale project was delivered at a time when high-rise

buildings were only beginning to come on the scene in India.

Authority guidelines surrounding fire engineering and drainage

were particularly vague and so provided a significant challenge.

We therefore became leaders and pioneers in India of suitable

approaches, particularly for fire engineering solutions, which could

be introduced appropriately and safely in this building type.

This project comprised of six 26 storey towers with basement car

parking together with clubhouse, offices and recreational facilities.

Meinhardt was retained to undertake integrated engineering design

for the buildings and the detailed design services for infrastructure

and utilities.

Value EngineeringAs is often the case, value engineering was required late in the

project but also had to be carried out quickly to meet client

expectations. It was important that this was achieved without

compromising the basic MEP systems.

The huge green podium over the basement was a particular

challenge and required Meinhardt to pre-plan points in the

basement ceiling to allow smooth drainage. Incorporating the

collection of rooftop rain water run-off and enabling use after

necessary treatment to augment the municipal water supply, was

just one of the sustainable measures that provided the client with

additional value.

Design In India

SPECIAL FEATURE

Bengal NRI complex is a joint collaboration between the government of West Bengal with the Shrachi , Emami, Sureka, MKJ, JB and Nahata Group.

IN PICTURESKOLKATA SPECIAL

This is a 67 acre township in a league of its own comprising

seven residential towers of G+45 and G+40 each with bungalows,

apartments, club house, restaurant, servant quarters, car parking

and other ancillary structures along with all the necessary

infrastructure.

To ensure a holistic approach and integration into the city,

Meinhardt has been appointed to carry out the infrastructure

masterplanning, as well as MEP engineering design services.

Value EngineeringIn the MEP design our electrical team had to revise the load

calculation and load distribution system to meet the revised

norms of CESC (Calcutta Electric Supply Corporation). Our

team reassessed the emergency backup for lighting and small

power loads, along with energy limiters. On analysing the shafts

space we found that they did not have enough space required for

accommodating single mains of huge capacity for the emergency

supply. Hence we suggested splitting the rising mains into multiple

ones and eventually were able to accommodate the whole system

within the available shaft and also cater for the emergency supply

requirement of the whole tower.

Bengal NRI Complex & Urbana IKolkata

India’s largest mixed use development township, covering an area

of 31.14 acres and featuring four residential towers of 36 floors

each. It comprises of 1600 flats, clubs, school and more than

1 million sq.ft of Shopping Mall, all planned to an international

standard. As of it’s the tallest building in eastern India which rises

upto 117 meters (384ft).

Value EngineeringA group of specialist structural engineers worked seamlessly

during the Concept & Design phase of this project. Due to the

reclaimed soil which was as upto 20 meters deep, there was no

bearing strength in the soil. Our foundation specialist Mr. Sumit

Verma carefully analysed the soil reports and offered a Bored cast

in situ piles of 750mm to 1000mm diameter upto 50meters length

below ground to take care of the huge permanent loading from the

superstructure.

Overall out team suggested use of high grade steel and concrete

which saved our clients 10 to 15% of the structural cost. This is one

of the most prestigious and successful township of India and has

become quite a landmark in Kolkata.

Meinhardt offers distinctive visual transparencyPT Kepland Investama has enlisted Meinhardt in the development of a new tower for the International Financial Centre (IFC) in Jakarta, Indonesia. Although it will only reach completion in 2013, IFC 2 aims to achieve the Green Mark Gold to recognise its energy efficient features.

Situated a mere 1.2-metre distance away from Tower One, the

construction of IFC 2 presents significant challenges due to its

constrained site conditions. In response to these challenges,

Meinhardt’s team developed a total façade and BMU system that

can be installed easily onto the building.

Due to the close proximity of the towers and to meet the authority

requirements, light weight and translucent glass panels are

integrated within the curtainwall. These panels offer varying

degrees of light transmission and visual privacy for the occupants.

In addition, as the building design features ten different angles, the

glass panels are specially positioned to let in the natural sunlight,

creating a feeling of transparency and openness. The angles

are synchronised with the surrounding buildings, enhancing the

environment aesthetically.

As Mr Domenico F. Lio, lead architect of NBBJ, pointed out: “the

soft natural light fills spaces that would otherwise require

artificial illumination, additional energy, and also have a

potential impact on lease rates.”

The 64,000-square metre development will be fully enclosed with

curtain wall and high performing low-E coated insulated glass,

allowing it to comply with the Green Mark Gold requirements set by

the Building Construction Authority in Singapore.
