This document discusses Industrialised Building System (IBS), which is a construction technique where building components are manufactured in a controlled environment and assembled with minimal work on site. It provides examples of early IBS use dating back to 1624 and its introduction in Malaysia in 1966. The benefits of IBS include reduced labor, waste and costs. However, only 15% of contractors use IBS due to lack of expertise and higher initial costs compared to traditional methods where labor is cheap. The document also categorizes different types of IBS and problems faced in its implementation.

1. What is IBS?
“A construction technique in which
components are manufactured in a controlled
environment (on or off site), transported,
positioned and assembled into a structure
with minimal additional site works”

1.1 History of IBS
a) Concept IBS in not new and can be traced
back to as early 1624
b) In 1624, panellised timber houses were
shipped from England to the new settlement in
North America
c) 1851 Crystal Palace in Hyde Park, London
and 1889 Eiffel Tower, Paris

1.2 History of IBS in Malaysia
a) Concept IBS in Malaysia is not new
b) In 1966 the two pilot project started by using
IBS concept. Namely?
i) Pekeliling Flat, Kuala Lumpur
ii) The Rifle Range Flat, Penang
c) In 1981-1993 PKNS acquired pre-cast concrete
technology from Praton Haus International,
Germany to built housing project

1.3 Characteristics of IBS
1.3.1 Five Characteristics of IBS are :
a) Industrial production of components though
prefabrication
b) Reduced labour during prefabrication of
components and site works
c) Modern design and manufacturing method
using CAD/CAM
d) Systematic Quality Control i.e ISO 9000
e) Open Building System i.e permitting hybrid
applications

2. Why IBS
Budget Speech 2005
“The Government is determined to ensure that
every Malaysian will have access to affordable
homes. During the period 1971-2003, the
Government constructed 490,000 units of low-cost
houses. The government intends to provide an
additional 100,000 units of affordable homes to be
implemented through the Industrialised Building
System (IBS).This system will ensure quality, save
cost, create a safer and cleaner working
environment as well as reduce the dependence of
foreign workers”

2.1 The Current Scenario of
Malaysian Construction Industry
This can contributes : Messy Sites, High Wastage,
Labour Intensive, Low Quality and Delays

2.2 Social Problems
a) Currently 75 foreign workers out of 100
construction workers
b) There are 318,000 foreign workers in Malaysian
Construction Industry
Let say one foreign worker gain RM400 pe rmonth;
RM400.00 x 12 months = RM5,000 per year,
318,000 x RM5,000 = RM 1.59 Billion per year
It shows the High outflow of Ringgit

13. Industrialised Building System (IBS)
2.3 Benefits
a)Reduction of site labour
b)Minimal Wastage
c) Less site material
d)Cleaner environment
e)Controlled quality
f) Neater and safer sites
g)Faster project completion
h)Lower total construction costs due to the above

3. Types of IBS
3.1 In general, the construction method can be
classified into 4 categories :
a) Conventional Method
b) Cast-in situ
c) Composite Method
d) Fully prefabricated

conventional methods and all types of IBSs
are categorized under these three

3.4 Based on structural aspects, IBS can be
divided into five major types :
3.4.1 Type 1 : Pre-Cast Concrete Framing,
Panel and Box System
e.g: Pre-Cast Columns,
Beams, Slabs, Staircase,
Toilet

4. Problems Faced by IBS
a) Only 15% contractors using IBS, Why?
i) Lack of Expertise / Lack of Experience
ii) Cost
22

23. Industrialised Building System (IBS)
4. Problems Faced by IBS
4.1 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)

4. Problems Faced by IBS
4.2 Cost
a) Only 15% contractors using IBS, because the
low labour cost in this country is the root causes
b) Labour cost is cheap, so why IBS?
