4. INDUSTRIALISED BUILDING SYSTEM (IBS)
WHAT IS INDUSTRIALISED BUILDING SYSTEM?
An Industrialised Building System refers to a technique of construction that is used broadly by the industry and government in Malaysia to represent the
adoption of industrialisation and the use of prefabrication of components in building construction. In IBS, the components are manufactured in a
controlled environment. These controlled environment can be either onsite or offsite where it is used to store, transport, position and assemble building
components into construction works.
The building components in the IBS system includes walls, floors, beams, and staircases.
HISTORY OF IBS
1624
Introducing of
the IBS in the
E u r o p e a n
countries and
t h e U n i t e d
S t a t e s
1963
I B S w a s i n i t i a t e d i n
M a l a y s i a w h e n t h e
Ministry of Housing and
Local Government made
visits to several European
municipalities with the
objective of assessing their
housing development
plans. It was to explore the
t h e c o n c e p t s o f
development in these
countries in further detail.
1964
Malaysia government launched a
project to test the efficiency of the IBS.
The key objectives looking to be fulfilled
include the acceleration as well as the
increase of affordable housing of
substantial quality here in Malaysia.
Present
As reported, there are 21 different
manufacturers and suppliers that are
promoting their components in
Malaysia. An IBS centre has also been
established in Jalan Chan Sow Lin,
Cheras, Kuala Lumpur who are
responsible for implementing strategies
and introducing breakthroughs in the
I B S te c h n o l o g y to i m p rove i t s
performance and quality in the
construction industry as well as to
reduce dependencies on foreign labour.
ADVANTAGES OF IBS METHOD
Attaining better quality and productivity
Reducing risk related to safety and health
Alleviating issues for skilled workers and dependency for manual foreign labour
Reduce overall cost of construction The building components in the IBS system includes walls, floors, beams, and staircases.
5. INDUSTRIALISED BUILDING SYSTEM (IBS)
TYPES OF IBS USED IN MALAYSIA
Pre-cast concrete framing
Precast concrete is a form of
concrete that is prepared, cast and
cured off-site, usually in a controlled
factory environment using reusable
moulds. Precast concrete elements
can be joined to other elements to
form a complete structure. It is
widely used in the IBS. It includes
precast concrete columns, walls,
slabs, beams and “3-D components”
such as stairs, balconies, lift etc.
Formwork system
Identified as the least prefabricated
types in the IBS. It is generally
involves concrete at the
construction site and high quality
control. It also provides a high
quality finishes in within a short
amount of time and demand
relatively less labour and materials.
Steel framing system
Steel framing system is sustainable
option for low-rise and mid-rise,
Includes steel trusses, beams and
column portal frame system and is
widely used in the construction of
skyscrapers, large factories and
exhibition halls that require wide area.
Panel and block system
May defines as those systems that
use 3D modules (or boxes) for
fabrication of habitat units. The
main feature of this system are its
internal stability as it can withstand
load from varius directions. It is an
interlocking of concrete masonry
units or lightweight concrete blocks.
Timber framing system
Involves prefabricated timber truss
beams and columns. Most of the
products listed in this category are
wooden building frames and roof
trusses. It is quite popular and
widely applicable as it provides
attractive designs and high aesthetic
values as chalets for resorts,
contributing very much to the
tourism industry.
6. INDUSTRIALISED BUILDING SYSTEM (IBS)
IBS WORK FRAME
1. Design considerations
Recognizing and analyzing the
design, determining the
conditions, considering the
productivity and optimizing
the layout
2. Manufacturing
Tally with the standar
d i m e n s i o n s o f t h e
manufactured components.
The manufacturing process
are based on the scedule
and construction process.
3. Delivering
The manufactured components
are then shifted to the site for
assemblage. At the preliminary
stage of production, the size of
the components must take into
account so that the components
can fit into the truck efficiently.
4. Assembly
Once the components
arrived on site, they are
then assembled quickly
to reduce time wastage.
These components are
assembled together into
a complete unit.
5. Completion
Finis h e s o f t h e b u i l d i n g
happens at this stage. The
facade of the building is
painted and coated to improve
the aesthetic quality of the
building.
7. PROPOSED IBS SYSTEM
STEEL FRAMING SYSTEM
TYPES OF STEEL FRAMING SYSTEM
Our apartment building implement the steel framing system as the proposed IBS system.
Steel framing system immense great strength which gives a lot of advantages to buildings. The other feature for steel framing is its
flexibility. It can bend without cracking, which is another great advantage as a steel building can flex when it is pushed on one side by
strong wind or earthquake. Another characteristics of steel is its plasticity and ductility which will avoid the steel to crack when
subjected to a great force.
Conventional steel fabrication
It is when teams of steel fabricators
cut the members of steel to the
correct lengths, and then weld them
together to make the final structure.
Botled steel construction
This construction occurs when
steel fabricators produce the
finished and painted steel
components, which is then shift
to the site and simply bolted in
place. The job is tremendously
fast as the only job at the site is
bolting the components together.
Light gauge steel construction
It is a type of construction that is
common for residential and small
buildings. This is similar to the wood
framed construction except that
light gauge steel members are used
in place of wood two-by-fours.
ADVANTAGES OF STEEL FRAMING SYSTEM
Fast building construction on site, as a lot of work can be pre-fabbed at the factory.
Flexibility allows them to resist dynamic forces such as strong wind or earthquakes.
Provide a wide range read-made structural sections such as I, C and angle sections.
Consists of wide range of joining method such as welding, bolting and riveting.

9. CASE STUDY
NOXX APARTMENT, TURKEY.
Architects : CM Architecture
Location : Istanbul,Turkey.
Area : 128.0 sqm
NoXX Apartment is located in a narrow
dead end in Cihangir. Due to the location
of the project and the short timing for
construction, conventional construction
techniques seem unattainable, therefore
a steel apartment building is designed
with an industrial sensibility and as a
homage to the rare standing structures
from early century typical of the area.
The underground levels of the building are
reinforced concrete while the upper levels
are established as steel structure.
Composite structure is left visible on purpose,
without using plaster, paint or any cladding
material in the inside and the outside .
27. IBS COMPONENTS
CAST IN-SITU RC FOUNDATION
A precast spread footing foundation is utilized as it suits to the scale of the project, a low rise apartment block. The selection of
foundation system eases the mobility into the site.
Economic due to control of foundation size
Shallow form of foundation needs a little excavation
Shape can be designed to accommodate tight sites
ADVANTAGES
INSTALLATION PROCESS // COLUMN TO RC PAD FOOTING CONNECTIONS
1.The footing for precast concrete foundations requires a foundation base to be installed onto the concrete spread footing.
2.The depth and width of stone base are in accordance with the width of foundation wall, the existing site’s soil load-bearing capacity, 3.and the height of
construction materials.
4.Concrete spread footing were utilised as the precast concrete foundation.

29. IBS COMPONENTS
STEEL COLUMN
The steel column that was incorporated into the proposed design are H steel columns, rolled steel with an H-shaped cross section with equal thickness in
the two parallel flanges with no taper on the inside surface. For the steel column to connect to the foundation, the foundation consists of cast-in base
plates, re-bar by bolting on the brackets to facilitate the structural support towards the steel beams.
High strength, the column is less likely to bend or wrap
Spacious as it allows builders to create larger open spaces because of its narrow size
Not obstructive as the size of the column does not have to be large in order to support heavy weights.
Load can be distributed over a wider area
Lesser risk of failure as it has the capability to support larger or wider structure
Lighter as it weighs less than a square column of the same size but can support a larger load making them
more efficient and economic
ADVANTAGES
INSTALLATION PROCESS
1.Steel columns are lifted up using wire ropes to be transported to its specific location (figure 1.0)
2.The column is then slowly placed on top of the foundation with re-bar aligned. (figure 2.0)
3.Base plate of the column is then secured with bolting. (figure 3.0)

30. IBS COMPONENTS
STEEL BEAM // STEEL I-BEAM
I-beams are often used as major support trusses in buildings, helping to ensure their structural integrity. An I-beam’s strength can
reduce the need for numerous support structures, letting builders create aesthetically-pleasing, wide-open spaces within buildings. I-
beams are comprised of a long vertical piece of metal called a “web “and shorter horizontal pieces called flanges. These pieces fit
together to create a beam whose cross section looks like the letter I.
Resists shear forces while its flanges resist bending moments; this allows the beam to excel at carrying shear and bending forces 2.in the plane of the
web.
Less likely to bend and warp
ADVANTAGES
INSTALLATION PROCESS // BEAM TO COLUMN CONNECTIONS
1.Steel beam are set and aligned into the column.
2.Steel beam is then bolded via a bracket metal plate onto the column.

COMPOSITE FLOOR SLAB REINFORCED WITH PROFILED STEEL DECKING
Composite steel floor deck consist of a profiled steel deck with a concrete topping. Included within the concrete is some light
reinforcement (see Figure 8.0). Indentations in the deck enable the deck and concrete to act together as a composite slab. The
reinforcement is included to control cracking, resist longitudinal shear and, in the case of fire act as tensile reinforcement. To develop
composite action between beam and concrete slab, shear studs are welded through the deck onto the top flange of the beam. A
result of two-way-acting composite floor is structurally efficient and economic to construct.
Great durability because it is resilient to weather, moisture, pest deterioration and has corrosion protection.
Excellent spanning capacities for greater strength and less deflection.
Act as a permanent formwork.
Speedy, safe and easy on-site handling due to it is produced in pre-cut lengths.
Cost reduction due to most of installation method are by hand and no heavy duty machines are required.

the roof is comprised of the IBS components which is a total of 71/100.
Throughout this project, we have learnt on the great advantages of using the
Industrialised Building Systems method in the modern construction industry. We have
learnt in depth on how this method is being constructed, the vital role it plays in order
to construct a building in a short amount of time. This is reflected through our research
studies in relation to the topic given (structural steel framing system). Through our
findings, we have also managed to learn to implement this method in designing and
constructing our apartment building. Lastly, we have also learnt to calculate the IBS
score based on the consturction materials that we have used for our apartment building.
On and all, there were many little details that we need to take note of in order to
minimise mistakes. Teamwork and good communication among team members is
important in order to get the right informatin in achieveing the objectives of this project.
