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 worksc) 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

12

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

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 Methodb) Cast-in situ

c) Composite Method

d) Fully prefabricated

3.2 Method b,c and d can be classified as non conventional methods and all types of IBSs are categorized under these three

1st ASSIGNMENT

-Form a group which is consist min of 5 members.

-Each group will elaborate what is a), b), c) and d)

-Please attach pictures and references to support your finding.

3. Types of IBS (cont’d)


3.3 The construction method can be classified into 4 categories :

Construction Methods

Conventional Non Conventional

Cast in-situCompositeFully Prefabricate

On site Off site

Precast ConcreteLoad Bearing

BlockSandwich Panel Steel Frame

Frame Panel Box

17



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

18



3.4.2 Type 2 : Steel Formwork Systems

e.g: Tunnel Formwork, Beam, Column and slab moulding form

19



3.4.3 Type 3 : Steel Frame System

e.g: Steel Beam, columns, portal frames, roof trusses

20



3.4.4 Type 4 : Prefabricate Timber Frame System

e.g: Timber frame, timber roof trusses

21



3.4.5 Type 5 : Blockwork Systems

e.g: Interlocking concrete masonry unit (CMU), lightweight concrete blocks

22

4. Problems Faced by IBS


a) Only 15% contractors using IBS, Why?

i) Lack of Expertise / Lack of Experience

ii) Cost

23


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)

24


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?
