2. INTRODUCTION
Industrialized Building System can be defined as
building systems in which structural components are
manufactured in a factory, on or off site, transported and
assembled into a structure with minimal additional site
works.
IBS is one of the improved building systems that are
being introduced to achieve the target of faster
completion with mass production of the building
elements in places out of its final location in a building.
It has been proven successful in some countries, namely
Finland, Denmark, Netherlands, Singapore, England and
the United States.
3. CHARACTERSTICS OF IBS
One of the major characteristics of the IBS is the Industrial
production of components through prefabrication, “OR”
sometimes highly mechanized in-situ processes i.e. permanent
steel formworks, tunnel forms, etc.
Reduced labor during prefabrication of components and site
works.
Modern design and manufacturing methods involving
Information Technology like usage of Computer Aided design
(CAD) and Computer Aided Manufacturing (CAM).
Systematic Quality Control i.e ISO 9000 principles.
Open Building Concept- permitting hybrid applications, and
adaptable to standardization and MC (Modular Coordination)
4. CLASSIFICATION OF IBS
There are various Industrialized Building
Systems (IBS) used throughout the world, and
they can be classified into three major
categories.
These categories are:-
1. Frame or Post & Beam System.
2. Panel System.
3. Box system.

In the evaluation of
the systems various
parameters such
as-
1.the industrialized
process used
2. transportation &
erection problems,
3.architectural
features
4.socio-economic
problems must be
considered.
6. FRAME SYSTEM
Frame structures may be defined as those structures that
carry the loads through their beams and girders to
column and to the ground.
Their important feature is the capacity to transfer heavy
loads over large spans.
Used in the construction of bridges, parking lots,
warehouses, industrial buildings, sport facilities and so
on.
7.
8. PANEL SYSTEM
Panel system may be defined as those structures
that carry the load through large floor and wall
panels.
Concrete panel systems are extensively used in
Europe for high rise building for ease of
construction purpose.
Used in Hollow core slabs, Interior & Exterior
Wall.

10. BOX SYSTEM
Box system may be defined as those
systems that use 3D modules (or boxes)
for fabrication of habitat units.
The main features of this system are in the
internal stability as it can withstand load
from various directions.
Require only large prefabricated sections
to be transported or handled at one time.

12. WHY IBS???
Scenario in construction industry compared to other
sectors is that the construction industry suffers from low
productivity, safety and quality control.
Due to the traditional labor-intensive practices, the 3- D
Syndrome (Dirty, Difficult & Dangerous) has always
been associated with the construction industry.
IBS is a good solution for these kind of problems of the
construction industry- messy sites, high wastages, labor
intensive works, low quality work, delays.
13. ADVANTAGES
1. Reduction of site labor
2. Minimal wastage
3. Less site material
4. Cleaner environment
5. Controlled quality
6. Neater and safer site
7. Faster Project Completion
8. Lower total construction cost
14. Low site workers requirement due to simplified
construction methods.
Quality-controlled and highly aesthetic end
products through the processes of controlled pre-
fabrication and simplified installations.
Reduction of construction materials at sites
through usage of pre-fabricated components.
Reduction or elimination of conventional timber
formworks and props which are replaced by pre-
fabricated components and alternative moulds
with multiple-usage capability.
15. Reduction of construction waste with the usage
of the standardized components and less in-site
works.
Cleaner sites due to lesser construction waste.
Safer construction sites due to the reduction of
site workers, materials and construction waste.
Faster completion of construction projects due
to the usage of standardized pre-fabricated
components and simplified installation
processes.
Cheaper total construction costs.
17. MODULAR COORDINATION
A modular building is a pre-engineered structure
that is flexible enough to satisfy virtually any
requirement, it is tougher than standard drywall
construction, expandable, can be relocated and
completely re-usable.
One obvious advantage that modular
construction has over conventional construction
is cost as not only it can one save up to 35% on
the initial construction costs like labor and
materials, but there are other benefits as well.
18. With increasing industrialization to the building
industry, steadily larger parts of buildings are
made up of prefabricated components, delivered
to the building site from the factories.
Evidently, some sort of dimensional coordination
of these component amongst themselves and
with the design are of paramount importance.
The full benefit of the industrialization is
impossible without standardization….AND..
No effective standardization is possible in the
building industry, without dimensional
coordination.
19. Modular coordination is a concept of
coordination of dimension and space in which
buildings and components are dimensioned and
positioned in terms of basic unit or module.
The basic module is known as 1M which is
equivalent to 100mm.
It is internationally accepted by the International
Standard Organization and many other countries
including Malaysia.
20. MODULAR CO-ORDINATION CONCEPT
Less wet work site.
Non dependence on
unskilled labor
Less modification on site
Promote Industrialization (component
manufactured in factory)
Through Standardization
Improves Productivity
21. CHARACTERISTICS OF MODULE
Industrialization friendly i.e. able to cater for
manufacturing, transportation and assembly
requirements.
Small enough in term of size in order to provide
the necessary flexibility in design.
Internationally accepted to ensure that it can be
mass produced to cater for global market.
Ergonomic i.e. able to improve the efficiency of
people by providing adequate space for human
livings and working conditions.
22. NECESSITY OF MODULAR COORDINATION
It provides a practical and coherent: method for
coordinating- the position and dimension of elements,
components and spaces in the planning and design of
buildings.
To provide guidance to building component sizing
which can reduce(as much as possible)the need to further
trim and shape the materials to fit together in
construction, hence, reducing wastage of labor and
material.
For mass production of building components in factories
which ensures good and consistent workmanship and
quality.
To permit standardization, which encourages the use of
standardized building components for the construction of
different types of building.
23. DIMENSIONAL COORDINATION is defined as-
A convention for the co-ordination of the dimensions of
building components and incorporating them in their
design, manufacture and assembly by means of a three
dimensional spatial references system of points, lines and
planes to which the position and size of a components may
be related.
The dimensional coordination is essential because of
the following reasons :-
To simplify design and documentation procedures and
allow the implementation of computer techniques.
To achieve optimum efficiency in the manufacture and
use of components and assemblies.
24. To avoid cutting or modifying components and
assemblies on site.
To standardize the profile and detail of joints
between components.
To Reduce non-standard or dimensionally
incompatible components and assemblies.
