The objective of this report are to increase
the understanding of building services
systems in a building through a real life
project. Furthermore, at the end of this report,
the integration of various building services
systems will be exposed. The basic
principles, processes, equipment of
numerous building services systems in a
building will be covered.

Therefore, we had chosen Telekom Tower as

Fire is a natural and social occurrence that has an impact on both
people and the environment (Moshashaei and Alizadeh, 2016).
Firefighting system is the must-have services in a building. Fire fighting
is the act of battling a fire. It is crucial because putting out a fire helps to
protect property, the environment, and human life. Among the
additional causes of destruction brought on by fires in buildings are the
costs of medical care, saving, disability benefits, death compensation,
and other damages (Hai-Yun, 2011, as cited by Ahmed and Khudair,

Water, the removal of fuel or oxidants, or chemical flame inhibition can
all put out a fire; however, because different types of flames are caused
by different materials, such as grease, paper, electrical equipment, etc.,
a particular kind of fire extinguisher may be needed. The extinguisher's
classification is based on the kinds of fires it is better suited to put out.




A sprinkler system is a fire extinguishing system 05
that uses water as the extinguishing agent. A water
supply system that delivers sufficient pressure and
flowrate to a water distribution piping system,
onto which fire sprinklers are connected, makes up
a fire sprinkler system, an active fire protection
method. Despite previously its only being utilized
in factories and huge commercial structures, now
the sprinkler systems for homes and smaller
structures are now reasonably priced.


There are four types of sprinkler system that are
usually used. The four various types of fire
sprinkler systems are wet pipe, dry pipe, pre-
action, and deluge. Each of these technologies
contributes to controlling fire damage and
preventing the spread of flames. These types of
fire sprinkler systems differ primarily in their
applications and activation mechanisms
(Witkowski, A., 2019).


Automatic Sprinkler System

In Menara Telekom Malaysia Berhad. The type of
fire sprinkler system adopted is a wet pipe
system, which has water-filled pipes. This type of
sprinkler also known as automatic system.
Facilities must maintain a temperature of at least
40 degrees because the system contains water. As
stated by Witkowski, A. (2019), wet pipe fire
sprinkler can be turned on easily. A fire sprinkler
glass bulb breaks and releases water when it
exceeds a specified temperature.

The majority of systems really use extreme heat as
the trigger rather than the common
misconception that smoke and or alarms set off
fire sprinklers. Only the sprinklers required to put
out a fire discharge water, which reduces the risk
of expensive water damage throughout a
structure. Each sprinkler head is individually
triggered by a specific temperature in its area.
(Team, Q. 2013)



The pipe is always filled with
water. In addition to that, the
sprinkler is kept closed by a tiny
glass bulb that contains a heat-
sensitive liquid.


When a fire started, the air directly
above it heats quickly. The hot air
is pushed toward the ceiling,
walls, or other spots where the
sprinkler heads are located.

3 The heat-sensitive liquid inside the
bulb expands when the air
surrounding them reaches a
specific temperature, creating
pressure until the glass bursts.


The high pressure water in the
sprinkler pipes forced out, and the
water sprays over a deflector plate
causing it to be distributed evenly
over the space.

Security system is a type of system in securing entry points into a building with
the sensors that communicate with a control panel installed in a suitable place
somewhere in the building. It is also a method of something that is secured
through the system of interworking components and devices. Security system is
consisting networks of integrated electronic devices that implemented together
with a central control panel which in purpose to against the criminal activities or
potential intruders. There are numerous options in the security system that can
be customized according to needs, suitable for individuals and families such as
smart door system with RFID, video surveillance, biometric access system and
many mores.

In Menara Telekom, there are three types of security system which consists of
CCTV, card access system and parking control. The purpose of installing an
access control system is to provide fast and simple access to those who are
authorized and restricting those who are unauthorized from entering the building
meanwhile for the CCTV to keep an eye on what is happening in the building.



Video surveillance or also known as closed- Card access system is a type of systems that

wireless communication links of camera that utilize to connect with
monitors, indicating the access to the footage to be restricted only to
those who are authorized. A CCTV system which consists of camera,
lens, recorder, and monitor can be scaled in and out, up, and down and
rotate in 360 degrees depending on the size of area to be monitored and
the types of system itself. It takes a continuous sequence of images,
which then relaying to the recording device to the display monitor. People
can view the photos as video footage through the time.

According to Video Surveillance in Public Spaces by Malaysian
Communications and Multimedia Commission (SKMM), the
regulations for the closed circuit television system is as below:

Door access system has a sensor that connected with a central control unit
that is installed in a convenient location somewhere in the building and be
control through a network. The control unit is connected to an alarm either by
an automatic telephone dialer or an Internet connection. This system is
available to 24-hours as it is connected to control unit that can receives an
intrusion signal. A wired security system uses a small radio transmitter to
transfer signals to the control panel as opposed to a wired security system,
which is connected by low voltage wires. If there is any power outage or
severed wires, the systems will depend on batteries power, and it will
automatically recharge when the panel is connected to the household power.

Access Control

The access control keypad has numeric keys
which look similar to the keys on a touch-tone
telephone. The access control keypad requires
that a person desiring to gain access enter a
correct numeric code instead of placing a card.

According to Uniform Building By-Laws 1984 (G.N. 5178/85), the
regulations for the card access door system is as below:

01 UBBL 133 - Interpretations: Final exit refers to the threshold that
separates 'still within the building' and 'out of the building'. The liability of
the design for the evacuation from the building ends at this point.

02 UBBL 166 - Every floor space shall provided at least two exits on the
basis that if one from them is inoperable, the other exit can function. This
'designing for redundancy' principle applies to all aspects of evacuation.

03 UBBL 169 - The protected passage from a storey exit that leads to the
final exit. It can include spaces that are designated as areas of refuge
anywhere between the storey exit and the final exit.

UBBL 171 - Exits that lead to an adjacent horizontal separated

UBBL 174 - Exits from a floor which is of a different level from the 05
final exit. If it is on the same level, a distance away from the final exit.
A storey exit must lead to the final exit.





Telecommunications, commonly referred to as telecom, is the
electronic transfer of information across long distances, including
voice, data, and video. This is a broad term that includes a variety of
information-transmitting technologies and communications
infrastructures, such as telegraphs, landline phones, mobile phones,
satellites, microwave communications, fibre optics, and radio and
television broadcasts.
An entire single communications circuit consists of two stations—one
with a transmitter and one with a receiver. Any station's transmitter
and receiver can be integrated into a single device known as a
transceiver. Electrical wire or cable, commonly known as copper,
optical fibre, electromagnetic fields, or light can all be used as the
medium for transmitting signals. Wireless communications refer to the
electromagnetic field-based transmission and receiving of data over
free space.


Wireless Fidelity A telecommunications technology known
(Wi-Fi) as Wireless Fidelity (Wi-Fi), uses radio
waves to send and receive digital signals
and consequently, data. It was also
known as Wireless Local Area Network
(WLAN). The Wi-Fi Alliance created the
acronym Wi-Fi to represent the
technology since its technical term IEEE
802.11, which stands for Institute of
Electrical and Electronics Engineers was
thought to be a little too complicated for

The wireless technology, Wi-Fi is used to
link computers, tablets, smartphones,
and other devices to the internet. Wi-Fi is
the radio signal that a wireless router
transmits to a device in the area, which
then converts the signal into information
you can see and use. A radio signal is
sent from the device back to the router,
which has a wired or wireless connection
to the internet. This makes nowadays
such a convenient time to be living,
providing Bluetooth, social networking,
real-time streaming, and access to a
limitless amount of information.

they share the same SSID and password. Unlike
range extenders, which communicate with the
router via the 2.4GHz or 5GHz radio bands, most Wi-
Fi system satellites use mesh technology to talk to
the router and to each other.



Site Survey
An extensive evaluation of all internet connection access points is
conducted as the first phase in every Wi-Fi installation in order to prepare
for the subsequent design and implementation steps.

Carry out a detailed plan for installing a stable Wi-Fi network when the site
survey is completed. Furthermore, provide a process map to future-proof
the Wi-Fi network and ensure that the administration guidelines are clear.

Install and integrate the Wi-Fi network as soon as a design plan has been
agreed on. Constantly check that the installer is complying to all rules
concerning the area.

Carefully test the Wi-Fi network at the building after installation is finished
to make sure it is performing at optimal efficiency.

The term "mechanical handling systems" refers to the equipment
that are used to manage the storage and transportation of goods.
They are vital in terms of providing a product distribution service
that is both effective and reliable. In the simplest form, mechanical
handling system is a way of moving goods or people from one
location to another. Some contemporary buildings and projects
often have some kind of mechanical transportation which may be
found both within and outside of these buildings. On the other
hand, the mechanical handling system will reduce the available
floor space, but it will make the structure of the building strong
enough to support the system. Depending on the building's design,
the mechanical handling system could result in a big and tall
structure. In addition, mechanical handling system will also affect
the cost since not only will there be an additional expense for its
installation and maintenance, but it will also raise both the selling
cost and the rental cost. Consequently, planning has to be taken
into consideration at a very early stage in the design process.


In this day and era, there have been a great deal of developments taking
place in a variety of industries, including business, computing, and
software. They have made substantial contributions to the advancement of
a wide variety of fields. You are able to appoint a metal box that will transfer
you from one level to another in a secure manner by pressing the switch or
the button. In point of fact, a building that is higher than four or five stories
is required to have at least one elevator installed. An elevator provides
simplicity and convenience for the majority of people, and it also makes life
simpler for those who have physical disabilities. Elevator, which may also
be referred to as a lift, is a vehicle that travels up and down a vertical shaft
to transport people and goods between floors of a multistory structure. The
vast majority of today's elevators are driven by electric motors, and they do
so with the assistance of a counterweight and by use of a network of cables
and sheaves(pulleys). The elevator, which allowed for the construction of
taller structures, was a significant contributor to the formation of the
distinctive urban topography of many contemporary cities. It also has the
potential to play an essential part in the continued growth of cities in the
future. According to our case study which is MENARA TELEKOM MALAYSIA
BERHAD, they use double deck passenger lift




An elevator is essentially a box made of metal that can take on a variety of
configurations and is suspended by an extremely strong metal rope. Within
the engine room, the sturdy metal rope travels via a sheave that is located
on an elevator. In this case, a sheave functions similarly to a wheel in a
pulley system by firmly grasping the metal rope. The use of a motor is an
option for operating this device. When the switch is set to the ON position,
the motor will be ready to run whenever the elevator travels between floors
or comes to a halt. The elevator may be built using a variety of elevator
components or elevator parts. The most important of these components are
the speed regulating system, the electric motor, the tracks, the cabin, the
shaft, the doors (manual and automated), the drive unit, the buffers, and the
safety device. This kind of lift is completely composed of a lift car that
travels vertically inside a lift shaft that has been specifically designed for
this purpose. The passengers are possible to traveled between floors at
quick speed. The control systems in the lift are typically built to provide the
most cost-effective distribution of passengers across the whole structure.
These elevators make highly effective use of the area it occupies, so it may
be installed in existing structures even when space is limited.


Users of the Menara Telekom Malaysia Berhad must take the

elevator up from the ground level to reach an even-numbered

floor. To reach a level with an odd number of floors, the user

must use the elevator from the lower lobby. The user pickup

and drop-off areas for the double-decker elevators are in the

lift lobby, which is situated in the centre of the building. The

whole building is equipped with 18 double-decker elevators

that are divided into three zones, each with its own set of

positions. 33



An elevator that has cabs placed one on
top of the other is referred to as a double-
deck elevator or a double-deck lift.
Because of this, passengers on two levels
that are practically next to one another
are now able to utilise the elevator at the
same time, which considerably increases
the passenger capacity of an elevator
shaft. In buildings where the amount of
traffic would ordinarily require a single-
deck elevator to stop at each level, a plan
like this one may enhance efficiency and
make use of the space more effectively.
For instance, a passenger could board the
lower deck (which only serves odd-

while 0a1nother passenger co0u2ld board the
upper deck (which serves even-
numbered floors) on the basement level.
This is because the cab that serves even
floors is positioned on top of the cab that
serves odd floors. When there is the same
amount of human traffic, standard single-
deck elevators take up more room in the
centre of the building than double-deck
elevators do. Because elevators take a
large amount of floor space, this makes it
possible for skyscrapers to make
considerably better use of the space
available to them.




Elevator Group Supervisory Control Systems, also known as EGSCS,
are the control systems that are responsible for the systematically
management of three or more elevators in a building in order to
ensure that passengers are transported as quickly and easily as
possible. When compared to Single-Deck Elevator Systems, Double-
Deck Elevator Systems (DDES) exhibit more sophisticated behaviours.
This is because the functionality of Double-Deck Elevator Systems is
expanded in DDES to allow passengers to input their destinations at
elevator halls. A recently created evolutionary approach that is
based on graphs is called Genetic Network Programming, or GNP (Lu
et al., 2007)


The Telekom tower was one of the first buildings to install a 6-star double-

decker lift for use in vertical transportation. This made it an early pioneer in

the field. This technique allows for a substantially greater number of

passengers and cuts down on the amount of time it takes to go to the top.

Additionally, there are four different zones for double-deck elevators, and in

order to reach your destination, you will need to use the elevator that is

designated for your level. For instance, the lift at zone 1 serves LG1 through

L18, whereas the lift at zone 2 serves LG1, L18, and L36. Regarding zone 3, it

includes LG1 lifts from L36 to L50, while zone 4 includes LG1 lifts from L50 to

L55. For the slowest speed, the lift can travel at is 2.5 metres per second, and

its maximum speed is 6 metres per second. Then, the typical wait time is

between 30 and 60 seconds. There are a total of 36 elevators, and the

building control centre serves as the location for the centralised monitoring

system while the cabin information System Display located within the Double

Decker elevators. 35

Elevator carrying capacity is mostly determined by platform area.
Each passenger need roughly two square feet to ride comfortably,
yet during rush hour, users will pack into an average of 1.3 square
feet per person. Increasing the platform size or the number of
elevators in a typical elevator takes up more room for hoistways
and leaves less for other uses.
Instead of expanding platform size and, therefore, hoistway space
consumption, engineers have been researching the alternate
potential of elevators with two platforms, one above the other. In
essence, the double deck elevator approach is analogous to
constructing a two-story colonial rather than a ranch home to
accommodate a large family on a short property.
Each double-deck elevator features an upper and lower cab in a car
structure that is about twice the standard height. The entrances
and interiors resemble those of traditional, single-deck elevators.
Users access the cabs from two lower terminal levels. The lower
terminal might have a split-level lobby, with elevator entrances on
the stress level and half a flight below, or on the stress level and on
a mezzanine level.
People travelling to odd-numbered levels use one terminal level;
those travelling to even-numbered floors use the other. Escalators,
steps, sloping moving pathways, or stationary ramps may connect
the two floors. Each double-deck elevator comes to a halt when it
reaches a level where passengers have pressed the necessary
control buttons.
Passengers will access and exit both upper and lower decks at
certain stations. However, at other stops, passengers will only be
able to enter or exit on one deck. Because certain stops allow the
double deck elevator to respond to requests for two levels, it often
requires fewer stops per trip than a standard, single deck elevator.
Total traffic handled in a given period is boosted further since
people access and exit both decks simultaneously, in less time
than a single car with an equal platform space. The time saved by
the double decker in passenger transfer allows it to finish each
journey sooner, make more trips in a given period, and transport
more people during that period.



Double deck elevators with building's access control system
As elevator users pass through security gates for
authentication, their destination floors are registered and
the destinations are grouped by elevator for efficiency
Users do not need to press destination buttons outside
ORinside of elevators, so operation of multiple elevators is
optimized for enhanced transportation efficiency and user
Instead of pushing up or down, users in smart elevators
must first pick the floor to which they desire to go before the
elevator can function. After that, they are given instructions
on how to access an elevator that will take them to their
final destination with the minimum amount of stops along
the route.
A mixture of the two configurations, the Private Elevator with
Private Access to Selected Floors provides an additional
layer of protection above the other options. A passenger will
not only need a card read to call the elevator, but he will also
need to complete a card read after he is already inside the
elevator. This will ensure that he is only allowed access to
the floors that his credentials permit for him to be on.
When a conventional Destination Control System (DCS) is
used, the Destination Operating Panel (DOP) is the sole
place from which calls may be sent. Because of this
particular reason, the card reader is exclusively included
into the DOP. Integration of a turnstile is something that can
be done so that a direct home or call function is activated
whenever a person goes through it.
Access control systems are able to perform pre-determined
actions in response to the status of triggers sent from other
systems, and they are also able to transmit triggers to
external systems such as security, fire alarm, video, and
emergency systems.



Should be easily accessible
Should be large enough to allow traffic to move in
both directions, without being obstructed by people
waiting for the lifts.
Double-deck elevators occupy less building core
space when compared with traditional single-deck
elevators for the same level of traffic. In
skyscrapers, this allows more efficient use of
space, as the floor area required by elevators is
