goverment project will use 50%
IBS components.
3. Housing projects which utilised
IBS components exceeding
50% will be given full
exemption on CIDB levy.

5. 1. Efforts to encourage the use of Industrialised Building System
(IBS) will be continued in order to achieve the objective of
reducing dependency on unskilled labour as well as foreign
workers
2. The Government will ensure that the IBS components meet the
Malaysia Standard MS 1064. The adoption of the Standard will
ensure quality and will also control construction costs.
3. Capital expenditure on moulds to manufacture IBS components
be given accelerated capital allowance to be claimed for 3 years.

6. The Philosophy

7. IBS concept
The key idea behind IBS is to move as much of the
construction process from the construction site into
the factory environment - Offsite construction
Example: Typical 2-sorey building
• Conventional method: Involve assembly of 1200 individual parts and thousands
of interfaces and joints – higher chances for chaos
• IBS method: Production of building components/modules at factory reduces on-
site assembly to only ~ 50 components or modules

8. What is IBS?
 DEFINITION: IBS is a building system in which structural
components are manufactured in a factory, on or off site,
transported and assembled into a structure or building with a
minimal additional site works
 A set of interrelated elements that act together to enable the
designated performance of a building
8

9. What is IBS?
 IBS is a construction process that utilizes techniques, products,
components or building systems which involves prefabricated
components and on-site installation
 The usage of IBS in Malaysian building industry is expanding,
catching up with civil engineering construction i.e. bridges, drains,
infrastructure projects

13. Why IBS???
IBS promises:
 Better control of the process resulting in better quality and faster
production resulting in higher productivity and lower cost.
 The cleaner and better working conditions of the factory will result
in safer and happier workers
 Specialization would result in greater mechanization resulting in
lower labor requirements, better quality control and less wastage

14. Why IBS???
IBS promises:
 Environmental impact of the construction process on the site is
also lower as a result.
 The other spin off effect is that the factory workers have better
housing and more stable working conditions. Factories if properly
run will result in more stable job orders.

24. SOLUTION?:
CHANGE FROM THIS…

25. …TO THESE.

26. IBS IN MALAYSIA….
 IBS is not new in the Malaysian construction industry,
particularly the usage of steel structures and pre-cast concrete
for the construction of bridges, drains and other infrastructure
projects.
 Nevertheless, usage of IBS in the Malaysian building industry is
still very low if compared to the conventional methods.

27. IBS IN MALAYSIA….
 The industry prefers to utilize the relatively cheap supply of
foreign workers to perform the labour-intensive construction
activities.; and at the expense of quality, speed and the
environment.
 However, the cheap rates and abundant supply of labour would
not last forever, and any disruption to the supply would generate
huge problems to the industry

28. IBS IN MALAYSIA….
 In going global, it is necessary for the local players to be efficient
and equipped with the relevant technology and experience.
 Therefore, since 1998, CIDB has been actively promoting the use
of IBS in the Malaysian construction industry.
 IBS Roadmap 2003-2010 was formulated to effectively
coordinate the industry towards industrialization; concentrating
on the usage of IBS in the building industry.

Industrialised Building System (IBS)
In 1966 the two pilot projects started by using IBS
concept. Namely?
i) Pekeliling Flat, Kuala Lumpur
ii) The Rifle Range Flat, Penang
In 1981-1993 PKNS acquired pre-cast concrete technology
from Praton Haus International, Germany to built housing
project

31. Characteristics of IBS

32. The characteristics of IBS are :
1) Industrial production of components though
prefabrication, OR
2) Highly mechanised in-situ processes i.e. permanent steel
formworks, tunnel forms, etc.

33. 3) Reduced labour during prefabrication of components and
site works.
4) Modern design and manufacturing methods involving
Information Technology i.e usage of Computer Aided design
(CAD) and Computer Aided Manufacturing (CAM).

34. 5) • Systematic Quality Control i.e ISO 9000 principles.
6) • Open Building Concept i.e permitting hybrid applications,
and adaptable to standardization and MC.
All of the five characteristics are equally important to
ensure the achievement of the proven benefits of IBS. As
such, all systems need to possess all of the above in order
to be accepted as part of IBS.

35. Benefits of IBS

36. BENEFITS OF IBS
1) Low site workers requirement due to simplified
construction methods
2) Quality-controlled and highly aesthetic end products
through the processes of controlled pre-fabrication
and simplified installations
36

37. 3) Reduction of construction materials at sites through
usage of pre-fabricated components
4) Reduction or elimination of conventional timber
formworks, replaced by pre-fabricated components
and alternative moulds with multiply-usage capability
37
BENEFITS OF IBS

38. 5) Reduction of elimination of props due to the absence
of conventional timber props and the usage of pre-
fabricated components
6) Reduction of construction waste with the usage of the
standardized components and less in-site works
38
BENEFITS OF IBS

39. BENEFITS OF IBS
7) Cleaner sites due to lesser construction waste
8) Safer construction sites due to the reduction of site
workers, materials and construction waste
39

40. BENEFITS OF IBS
9) Faster completion of construction projects due to the
usage of standardized prefabricated components and
simplified installation processes
10) Overall, a cheaper total construction costs, made
possible due to all of the above
40

41. Types of IBS

42. 42
In general, the construction method can be classified
into 4 categories :
a) Conventional Method
b) Cast-in situ
c) Composite Method
d) Fully prefabricated
Method b,c and d can be classified as non-conventional
methods and all types of IBSs are categorized under these
three

43. 43
The construction method can be classified into 4
categories :

44. FIVE COMMON TYPES OF IBS
Based on the structural aspects of the systems, IBS can be divided
into five (5) common types :
 Type 1 : Pre-cast Concrete Framing, Panel and Box Systems
 Type 2 : Steel Formwork Systems
 Type 3 : Steel Framing Systems
 Type 4 : Prefabricated Timber Framing Systems
 Type 5 : Block work Systems

45. 1. Precast Concrete framing, panel, box
systems
PC columns, beams, slabs, 3d-components (balconies, staircases, toilets,
lift chambers, box girders, etc)

46. 2. Steel formworks systems
Tunnel forms, beams and column moulding forms, permanent steel
formworks (metal decks), etc

47. 3.Steel frame systems
Steel beams and columns, portal frames, roof trusses, etc

48. 4. Prefab timber frame systems
Timber frames, roof trusses, etc

49. 5.Block work systems

63. Problems Faced

64. 64
Industrialised Building System (IBS)
Only 15% contractors using IBS, Why?
i) Lack of Expertise / Lack of Experience
ii) Cost

65. 65
1. Lack of Expertise / Lack of
Experience
a) Lack of experience practicing/designing IBS by the
consultants/contractors/clients
b) Short of experience workers in the manufacturing and
installation works (most of them are foreign workers)
c) Defect works by previous pre cast system (close
system)
d) QS lack of experience pricing the IBS projects (most
of them not pricing the total cost of project)

66. 66
Industrialised Building System (IBS)
2. Cost
Only 15% contractors using IBS, because the low
labour cost in this country is the root causes
 Labour cost is cheap, so why IBS?

67. Modular
Coordination

68.  MC is an international system that standardises the
measurements in buildings
 Based on ISO standards, it is formulated to coordinate
the positions and dimensions of components and
spaces in building designs
68

69.  MS 1064 and ISO standards specify that MC is a
concept of coordination of dimension and space, in
which buildings and components are dimensioned and
positioned in terms of basic units or modules, known as
‘1M’ which is equivalent to 100mm, and this is accepted
not only by countries implying ISO standard but also
internationally
69

70.  Facilitates cooperation between building designers,
manufacturers, distributors, contractors and authorities
 In the design work, enables buildings to be dimensioned
so that they can be erected with standard components
without undue restriction on freedom of design
 Optimizes the number of standard sizes of building
components
70

71.  Permits a flexible type of standardisation, which
encourages the use of a limited number of standardised
building components for the construction of different
types of building
 Encourages interchangeability of components as mush
as possible, in whatever materials, forms or methods of
manufacture
71

72.  Simplifies site operations by rationalising setting out,
positioning and assembling of building components
 Ensures dimensional coordination between installation
(e.g. equipment, storage units, other fitted furniture) as
well as with the rest of the building
72

73. IBS PROJECTS IN MALAYSIA

74. 74

75. Challenges in IBS

76.  A pre-requisite for IBS is the adoption of MC by all
parties from the submitting technical consultants to the
approving authorities
 In Malaysia, MC is hardly used in building design
76

77.  The reality in our context is that most building
specialists still apply measurements in terms of feet
e.g.18-footer house instead of 6-meter house
 For this system to be successfully utilised, both public
and private sectors would need to play their roles in
educating the local construction industry players
77

78.  Aside from voluntarily changing in mind set, there must
be some push factors to catalyse the shift in mindset
 Incentives and regulatory requirements for the
introduction and adoption of IBS should be the next
concrete plan of action to be spearheaded by CIDB
