I INTRODUCTION

Petronas Towers (Kuala Lumpur, Malaysia)

452 meters high

The worl d's tall est reinf orced concrete off ice bui lding,

a symbol of the new Asia

Malaysia is a nation on the rise. In its energetic capital Kuala Lumpur a

gigantic project is under way that symbolizes the emerging of the new Asia. The

Kuala Lumpur City Center (KLCC) project is a complex of office buildings, hotels

and an industrial center. At its heart is the Petronas Twin Towers intelligent office

building, which began construction in 1994.

The 88-floor Petronas Twin Towers have stood 452 meters tall, surpassing

the 443-meter Sears Tower in Chicago to become the world's tallest building.

Among reinforced concrete buildings this stunning architectural triumph will also

far exceed the 295 meters of Chicago's 311 South Wacker Drive. Soon Asia will be

home to the world's tallest building.

The soaring twin cylindrical towers appear to embrace their smaller

adjoining wings, and are connected by a sky bridge at the -meter level. The metal

curtain wall adopted for the exterior design reflects Islamic architecture, blending

tradition with a futuristic image and achieving a rich beauty that sets this building

apart from earlier skyscrapers.

Nowadays this intelligent building is applying the latest in architectural

engineering technology to create the world's tallest building.

Petronas Towers is raising the curtain on the new Asia, and adding a bright

page to architectural history.

I C. LITERATURE REVIEW

1.1 WHAT TECHNOLOGY ?

The new technology era that we shall be witnessing in the next

millennium will focus more on technologies that encapsulate knowledge-

based systems. We shall be talking about intelligent systems that react

dynamically on data input. Theses knowledge based systems will almost

always rely on high technology information technology equipment. Most

people may think that such technology is better discussed in other forums

such as electronics, computing, electrical or mechatronics but the painful

part about technology is the indirect impact that it may have on all other

aspect of our lives. It should not be taken for granted that such technology

will not affect Civil Engineering work, as technology itself is currently

being used in most civil engineering design systems. It becomes more

complex when human needs on housing and infrastructure facilities

change with the coming of new technology. It therefore becomes

important for civil engineers and anybody dealing with civil engineering

work to acknowledge the technologies concerned.

The technology incumbent in the millennium would be technologies

related to the use of up-to-date information on all aspect of design and

operation. It can be coined simply as Information Technology (IT). This is

clearly manifested in the vision of Malaysia to implement the Multimedia

Super Corridor, which shall focus on the efficient use of information

technology in all its development and functions. Town and regional

planners need to think about regional development with infrastructure to

support the efficient use of information technology. Building architecture

and design need to cater for information technology device to be

introduced within buildings. Structural members designed by civil

engineers must incorporate possible fluctuation of loads due to the

presence of IT driven parts such as mobile roof that react to the position of

the sun and others.

1.2 EFFECT OF TECHNOLOGY

The advent of new IT equipment for measurements as well as design

changes the way an engineer would work in the design office. New

surveying instruments that incorporate IT concepts allows surveyors and

civil technician to conduct better and faster site investigation. Construction

control has been made accurate through the use of such equipment.

It is through the availability of these devices that we may have to

change some of the way we work and perhaps some of the design criteria in

our architectural and engineering design. Building services thus become one

of the important design aspects to be taken into consideration in civil

engineering construction work. Building structures need also take into

account that part of the structure that may need to host special IT devices to

monitor structural behavior and even perhaps control some of the dynamic

movement of the structural member.

These technology also affects other periphery activities such as

highways, wastewater treatment plants, bridges and dams may require some

review as to the additional high technology design tools that are available

now and the provisions such design need to consider to include IT related

devices in their structures.

1.3 INTELLIGENT TOWNSHIP

The development of the Multimedia Super Corridor (MSC) between

Kuala Lumpur City Center to the new Kuala Lumpur International Airport is

an example of an Intelligent Township. The whole development incorporate

construction techniques that take into account the preservation of the

ecology around the development area as well as ensuring that the various IT

infrastructure is blended carefully within the built structure. All structure has

provisions to include IT services that is built within its central building

services ducting and external infrastructure had to be built in tandem with

5


9/35

the development of the cables required for the information superhighway. It

is envisioned that all building and structures within the MSC are wired to

have IT services available upon completion of the project.

1.4 INTELLIGENT BUILDINGS

The process of designing, constructing, starting up, controlling and

maintaining an intelligent building is very complex. The construction of

such building requires the engineer to understand the various devices require

to be installed within the structures. Such devices require an intelligent

system to be developed to manage interactively the environment within the

building. If done properly, the final product delivers comfort, safety, and a

healthy environment and operates efficiently at reasonable cost. The key to

managing this complex process of designing and operating buildings

efficiently lies in the ability to manage information, deliver it efficiently to

the proper controlling equipment and devices, and to use it effectively for

the control of the building environment.

Among the type of intelligent buildings are designed to be energy

conscious yet environmentally comfortable to its occupants. This would

usually be building that stores solar energy for its energy supply and

maintains its comfort through having properly designed windows and

opening within its structure. There might be a need to allow certain parts of

the building to be mobile.

Special system need to be developed an in corporate within the

building services control system to manage and monitor the environment of

the building.

10/35

1.5 SYSTEM INTEROPERABILITY AND CONTROL

The trend in equipment design and control systems is to embed

greater intelligence in individual components. This distributed

intelligence present new opportunities to optimise dynamic building

systems resulting in lower energy use, energy cost and maintenance costs

while maximizing building performance environmental quality and comfort.

Tomorrows control system will be networked to operate as

integrated systems. The system will include a robust performance tracking

database technology to monitor and archive information on a broad spectrum

of building systems and their real time attributes including HVAC, lighting

and shell component s. Integrated building systems and their control

technology will be linked to software modules that compare actual

performance to original design objectives, metrics and functional intent.

Some specific control developments will include:

Adaptive/optimized/self-generating control algorithms:

Development of techniques whereby control algorithms adapt

to changing building or system conditions adjust, set points

and eventually algorithms themselves to be optimal and

eventually support automatic generation of control strategies

based on the equipment and systems present

Advanced control technique: Development of control

techniques based on artificial neural networks, fuzzy logic

and genetic algorithms.

7


11/35

The following elements of interoperable and integrated information

across the building life cycle:

Formats for data exchange between design tools, commissioningtools, controls and sensor suites, facilities maintenance management

systems and related software.

Standardized schema for archiving building simulation,

commissioning, control and operational data sets.

Process and workflow management techniques in the use ofinteroperable and integrated systems to ensure that data required as

input to software modules are supplied by the database archive or

related software module.

A user interface or browser that can interact with the data archive to

obtain a global view of the data for a building project.

II FINDINGS

2.1 CONCEPTS

The concept of KLCC is a self-contained, city-within-a-city.

The integrated mixed-use development provides more than 1.67 million sq.

meters (18 million sq. feet) of:

commercialretailhotelresidentialentertainment facilities

The winning Master plan submitted by Klages, Carter, Vail & Partners

delineated the site into 22 freehold lots located around a 20-hectare (50-acre)

park.

The KLCC project is being implemented in phases. Phase One was launched in

1992 comprising:

the 88-storey PETRONAS Twin Towers; Suria KLCC - the six-level, 1.5 million sq. feet shopping centre; the 49-storey Menara Maxis; the 30-storey Menara Esso; the 32-storey Mandarin Oriental Kuala Lumpur Hotel; a 20-hectare (50-acre) Public Park; two District Cooling Centres; a Mosque

2.2 KLCC Logo:

The logo is derived from a "Dualism Theme"; the twinning of KLCC with

the city itself. The corporate colours are in blue and green. Blue for the highrise

with the blue sky and waterscape, green for the park and the landscape.

Architect

The 88-storey PETRONAS Twin Towers are designed by Cesar

Pelli, the award winning, world renowned architect and founder of the firm

of Cesar Pelli and Associates. Other prominent works of the former dean of

Yale University's School of Architecture include:

Canary Wharf, London World Financial Centre, Manhattan Crile Clinic Building, Cleveland Rice University's Herring Hall, Houston Carnegie Hall Tower, New York City Owens-Corning World Headquarters, Toledo

2.3 BUILDING STRUCTURE & MATERIALS USED

2.3.1 PETRONAS Twin Towers At A Glance

Number of storeys = 88

Height = 452 meters above street level

Total built-up area = 341,760 sq.meters (3.7 million sq. feet)

Design/Architecture = Cesar Pelli & Associates [U.S.] in association

with KLCC architects.

Location of skybridge = Levels 41 and 42

Length of skybridge = 58.4 meters

Height of skybridge = 170 metres above street levelVertical transportation = 29 double-deck high speed passenger

lifts in each tower

Number of escalators = 10 in each tower

Stainless steel cladding = 65,000 sq. metres

Vision glass = 77,000 sq. metres

Concrete [various strengths up to grade 80] = 160,000 cubic metres

in the superstructures [see also foundation description below]

Steel = 36,910 tonnes of beams, trusses and reinforcement

Foundation = 4.5 metre [15 feet] thick raft containing 13,200 cubic

meters of grade 60 reinforced concrete, weighing approximately

32,550 tonnes under each Tower, supported by 104 barrette piles

varying from 60 to 115 metres in length.

The floor-plate of the Tower is designed based on geometric

patterns common in architecture of Islamic heritage. It is composed of two

rotated and superimposed squares with small circular infills. These

geometric figures have been described by architects as symbolising unity,

harmony, stability and rationality - all important principles of Islam.

Like the exterior design, the Towers' entrance design was also

inspired by the country's cultural heritage, incorporating contemporary

Malaysian motifs adapted from traditional handicrafts such as songket and

12


16/35

timber carvings. The overall character of the building is high-tech and

international but distinctively Malaysian.

At the podium level, the PETRONAS Twin Towers feature the following :

The 864-seat Dewan Filharmonik PETRONAS, a venue of architecturaland acoustic distinction. It is also home to the Malaysian Philharmonic

Orchestra.

A reference library on energy, petroleum, petrochemical and relatedindustries.

The Towers were topped-out in March 1996 and occupation began

in early 1997. Tower One is currently being occupied by PETRONAS, the

state-owned petroleum corporation. Tower Two is being occupied by

PETRONASassociate companies while the remaining space is being leased

out to multinationals.

The PETRONAS Twin Towers are located on the northern boundary

of the Multimedia Super Corridor (MSC) and has state-of-the-art

communication facilities. MSC is the launching pad to propel Malaysia into

the frontline of the information age.

2.3.2 SkybridgeThe skybridge is an essential functional component linking the Twin

Towers to facilitate movement between the two towers.

The 58.4 meters double-decked skybridge is located at levels 41 and

42 joining the sky lobbies situated in both towers.

Engineering Design

The structural system selected utilises a 'two-hinge arch' springing

from supports at level 29 and rising at 63 degrees to support a pair of parallel

two-span continuous bridge girders at Level 41.

The structure of the two-level bridge is conventional framing

constructed of structural steel with beams moment-connected to columns

which bear on the level 41 continuous girders. The bridge is 58.4 m long and

weighs about 750 tonnes.

The two-hinge arch supporting the bridge has rotational pins

(spherical bearings) at the end of each leg or 'spring point' and at the top or

'crown' of the arch (bearings). The main bridge girders have a rotational

(centering) pin directly over the arch crown to permit the crown to rise and

fall as the Towers move closer or further apart.

The arch is a centering device, equalising joint movement at both

Towers. As the Towers move together or apart, the legs change slope, the

spherical bearings rotate at spring points and the legs flex at their top end.

The bridge mid-point sinks or rises, flexing the two main girders.

The girders are pinned on the arch crown, which stays centered

between the Towers, while both girder and blocks slide on pads. The mid-

span centering pin and two girder slip pads accommodate this movement.

Continuous expansion joints provided through the level 42 and 43

structure, facade and roof to each side of the bridge mid point. Providing

14


18/35

expansion joints at mid-point reduces the effect of girder flexure on bridge

glazing, as window panel movement is then limited to each half-span rather

than cumulating over the whole girder length.

When the Towers move side-to-side in opposite directions, or when

they 'twist', the arch spring points twist on the spherical bearings and bridge

end bearings slide in opposing directions guided by 'sliding keeper' blocks

on bridge centreline.

In the event that it loses its arch support, the bridge structure would

not collapse but deflect and stay in position.

Lifting of Skybridge

VSL Heavy Lifting, a specialist in this field, was appointed for the

lifting of the skybridge studies and preparation for the lifting was carried out

for more than a year in several countries including the United States and

South Korea, simulating various wind and weather conditions including

those based on actual load data over the past 50 years.

There are nine main steps in the lifting of the skybridge.

STEP ONE

The skybridge's legs are lifted up one at a time by tower cranes. Once

they are in position, control cables are used to lower them over their

permanent bearings at level 29.

STEP TWO

The two end block girder frames of the skybridge are lifted

individually. The blocks are installed about 100mm above their final

position at level 41. They are also retracted about 100mm into the tower to

provide sufficient clearance for the skybridge centre section during lifting.

15


19/35

STEP THREE

The four lifting jacks located at level 50 of both towers are connected

on the bridge centre. The other four lifting jacks located on level 48 of both

towers are connected to the bridge ends.

STEP FOUR

The centre section which weighs 325 tonnes is lifted about 11 metres

and restrained. This is to allow the upper 10 metres of the legs to be

connected to the girder on the bridge.

STEP FI VEAfter a final check, lifting of the centre section commences.

STEP SIX

At a minimum lifting speed of 12 metres per hour, the centre section

is gradually lifted to its final level.

STEP SEVEN

Steps Seven to Nine took about two weeks. A temporary connection

secures together the centre section and the end block girder frame to ensure

there is no stress.

STEP EIGHT

The legs are moved into place. When the legs are in their final

position, the skybridge end blocks are lowered on their permanent bearings

at Level 41. The centre section is then lowered to meet the legs.

STEP NINE

After the lifting system has been removed, the floors were concreted,

the skybridge roofed. The maintenance equipment is set up on stainless steel

rails on top of the bridge.

16


20/35

At about 7.40 p.m., on 9 August 1995, after 32 hours of lifting

operation, the sky bridge was lifted to its final position at the 41st and 42nd

levels of the PETRONAS Twin Towers.

2.4 BUILDING CONTROL SYSTEMThe Building Control System [BCS] provides central management

and monitoring for air conditioning control, lighting control, and electrical

and chilled water status monitoring, as well as providing energy

management services.

The local area network system is based on a two-tier LAN structure,

where the primary network links the controllers to the command centre and

the secondary LAN facilitates communication with the end devices. The

BCS also interfaces to the life safety system, which is designed to overridethe BCS, in the event of an emergency.

The air conditioning requirements for the KLCC Development,

including the Towers is served by a 30,000-ton chilled water plant [District

Cooling Centres], which combines natural gas-driven cogeneration

equipment with various forms of steam turbine-driven chillers and electric

chillers.

The air-conditioning system selected for the Towers uses the latest

development in floor-by-floor air handling units, utilising the chilled water.

The floor-by-floor system solves the problems of acoustics, compactness,

ease of maintenance and control.

This system also provides the most advanced approach to engineered

smoke control. It allows for a pressure sandwich between the floor on fire

and the adjacent floors, thus allowing the fire to be contained during the

evacuation process.

The raised floor system utilised in the Towers allows for the effective

flexible distribution of electric power and telecommunication cables to meet

current and future needs.

18


22/35

2.5 BUILDING SECURITY SYSTEM

The Building Security System [BSS] is designed to operate via a LAN

[local area network]

High level software running on the integrated security network captures

all data to ensure fully automated coordination among the BSS sub-systems,

which include: -

Card Access and Alarm Monitoring System Voice Intercoms Alarm Monitoring System Audio Alarm Surveillance System Closed Circuit Television System - CCTV Photo Identification System

2.6 TELECOMMUNICATION SYSTEM

At the heart of the building management system is a structured

cabling system comprising vertical and horizontal cabling; inter building

cabling and connectivity to telecommunications carrier companies. The

system is designed to achieve maximum flexibility to accommodate present

and future communication needs.

Connectivity is provided from the main subscriber distribution frame

to the end-user workstations, minimising re-cabling and cable-removal.

The telecommunications infrastructure is designed as a local loop

communications system within the boundaries of the KLCC site. The hub of

the system is a Central Telecommunications Office [CTO], which serves as

a local communications exchange and gateway to the outside world.

19


23/35


24/35

2.8 ELEVATOR SYSTEM

The PETRONAS Twin Towers are serviced by a total of 76 lifts, of

which 58 are double-deck lifts. The double-deckers result in better utilisation

of the core space and require less hoistway thus maximing the efficiency of

passenger transportation.

The system features two passenger cabs, one above the other in the

same car frame, sharing the same hoistway. Each double-deck unit is

capable of carrying 26 persons per deck.

The shuttle elevators can carry 26 persons per deck, or 52 per trip,

while each of the other double-deck lifts is designed to take 23 passengersper deck. Traveling time is between 3.5m/second and 7 m/second depending

on which zone they are servicing.

Tenants / visitors going to 'even' floors embark on lifts at the ground floor while

those traveling to 'odd' floors take the escalator to the mezzanine level before

embarking on their respective lifts.

25/35

2.9 PUBLIC PARK

The beautifully landscaped park at KLCC is the last inspired

masterpiece by the versatile and talented Brazilian master of gardens, the late

Roberto Burle Marx.

Spread over 50-acres [20-hectares], the lush tropical garden provides a

haven of tranquility for those seeking a respite from the stress of city life

The KLCC Park is unique in its theme and concept. Designed to

showcase a heritage of tropical greenery by integrating man's creation with

nature, the beautifully landscaped KLCC Park offers a calm and harmonious

environment in the midst of the hustle and bustle of a busy and dynamic city.

The late Roberto Burle Marx uses a combination of trees, shrubs,

structures of cement, stones and wood as well as various water features in his

creations. Elements of shapes, texture and topography are merged to create

attractive and breathtaking masterpieces while at the same time imposing an

illusion of space. Colour and form are achieved by using various combinationsof trees, shrubs and sculptures, thus dispelling the notion of a garden as a static

creation.

The conservation factor was another key consideration in the planning

of the park. About 23 of the mature and rarer specimens were saved from the

former Selangor Turf Club, and eventually transplanted on to the park

grounds.

About 1900 indigenous trees and 66 species of palms have been

planted at the park. Much thought proceeded the selection of these plants, with

the objective of encouraging bio-diversity. Among other attractions at the park

are the magnificent lake symphony fountains, programmed to provide

numerous different dramatic animations following a Symphony Overture

sequence, the ornamental water features, the children's pool and the children's

playground.

22


26/35

The park is well interspersed with various amenities such as shelters,

benches, rest areas, drinking fountains and public toilets. For health

enthusiasts, there is also a 1.3 km jogging track encircling the park.

Another interesting element of the park is the 43 meter elevated bridge.

The centrally located bridge provides visitors with a vantage view of the park

and the majestic PETRONAS Twin Towers.

Part of the park is also designed as a haven for birds and other local

fauna. Much research and thought went into the selection of indigenous tree

species whose fruits attract local and migratory birds. Through such careful

effort, it is expected that the KLCC Park in the heart of bustling Kuala

Lumpur will become an important link in the 'bird corridors' of the region.

PARK PLAN

Lake Symphony

The Symphony Lake with an approximate area of 10,000 square metres

features mesmerising fountain displays. The displays consist of 5

programmers with over 380 individually sequenced effects shooting up to a

maximum height of 42 metres. These effects are displayed along the arc and

the two rings totaling 80 metres in length. The Lake Symphony fountains are

on from 12 noon till 2.00 p.m. and 6.00 p.m. till 11.00 p.m. on weekdays.

23

Especially for weekends and public holidays, the fountains are on from 10.00

a.m. till midnight.

Jogging Track

A 1.3 km. long jogging track is laid with EPDM, a special rubberised material

to ensure comfort and safety for fitness enthusiasts.

Rest Areas

Rest areas are located on various nodes of the interconnecting footpaths. They

are numbered as shown on the maps found on the Park's entry and feature

identification signs. The numbering system can be used as points of reference

for way finding and setting a rendezvous.

Ornamental Water Features

Waterfalls, Cascades, Reflecting Pools and Bird's Pool add to both the

excitement and tranquility of the respective zones in the park.

Other Amenities

The KLCC Park has been provided with various amenities such as

Toilets complete with modern fittings and facilities for the disabled and

baby change.

Male and female changing rooms annexed to the toilet near the Children's

Pool.

Drinking fountains with filtered water.

Shelters and benches.
