IBS

INDUSTRIALISED
BUILDING SYSTEM

Director-General of Public Works

Warmest congratulations to CKAS
for successfully publishing the IBS
FAQ. JKR has been vigilant in
taking consistent measures to ensure the
adaptation of IBS system in the Government
building construction industry. Hence, thorough
understanding on the IBS concept is crucial in
promoting efficiency in construction methodology
and reduction in cost through technology. Hopefully
this FAQ could be a quick reference to

all of us in better understanding and applying
the IBS concept in our daily task.

Dato’ Ir. Haji Mohamad Zulkefly B. Sulaiman

Engineering Director (Structure Expert)
performing duties of Senior Director
I would like to extend my deepest
appreciation to Research and
Development Division of CKAS for
successfully publishing the IBS’s FAQ for the first
time. This FAQ Document is a brief reference
document describing IBS implementation rules for
the government project. Hopefully these FAQs are
useful to all parties especially those involved in

the construction of government buildings so that
all projects can be completed more efficiently
in line with the government's aspirations.

GENERAL & PLANNING

Q1: What is A system or construction method in
Industrialised which the components are:
Building System
(IBS)? Manufactured under
controlled conditions
(either on site or off site)

Transported and assembled
at construction site with
minimum workers

Precast Steel
Concrete Frame
System System

Blockwork Q2: TYPES OF Timber
System IBS ISBYSSTEM Frame
INSMYASTLEAMYSIA System

Reuseable Other
Formwork Innovative
System
System

Q3: What are the advantages of using IBS?

Minimize waste production with
systematic factory working environment

A safe and stable working platform with
complete installation elements

Advantages Faster work completion with the usage
of pre-installed components

Safer, cleaner and more organized
construction site

Reduce support materials by the usage
of complete installation element or
support system for the onsite pouring
process.

Lower total construction cost based on
all of the factors above.

*(cheaper with larger size project)

Q4: What is Modular Coordination (MC)?

Modular Coordination (MC) is a dimension system that
involves the concept of space coordination where the
buildings and components are dimensioned and positioned
in a module known as 1M (common unit of measurement,
1M is equivalent to 100mm).

Prefabricate Standardized Repetitive
components components design
based on MS

1064

Q5: Do MC need to be Quality
implemented in IBS? control

Utilisation of MC is one of the Increasing
key factors in ensuring IBS productivity
system implementation
effectiveness as it strengthens
the industry through:

Q6: Are there any instructions to implement IBS in
government projects?

Yes, Malaysia Treasury has
issued Treasury Circular of
Malaysia PK 1.4 for the
Implementation of
Industrialised Building System
(IBS) In Government Project
which stipulates instructions
for implementing IBS in
government projects.

Q7: What are the objectives of IBS implementation?

Standardized the Accelerate
design construction period

To improve the IBS Reduce dependency
quality and Impleme. ntation on foreign worker

productivity of Objectives
construction

Q8. Can application
of IBS be exempted?

For project worth more However, written approval from
than RM10 million, Controlling Officer is sufficient
prior written approval for condition as below:
shall be obtained from a) Project work worth less
the Director General of
Public Works than RM10 million except
for projects identified by
JKR for IBS implementation
b) Renovation of existing
buildings and does not
involve the construction of
new buildings
c) Completion of abandoned
project that originally not
IBS implemented

Q9. What is the method to
accelerate the implementation
process of IBS in government

projects?

By using ‘Pre-Approved
Plan’ where the standard
design is designed based on
IBS method

Q10: Which ‘Pre Approved Plan’
references can be document can be
used in estimating the referred as it contains
cost of a project that architectural drawings,
will be implemented structural drawings and
BQs that is necessary for
using IBS? cost estimation.

Q11: Who is
responsible for
appointing an
IBS supplier for
a project?

Q12: What By referring to
documents / Orange Book
references can be as published
used to obtain by CIDB
the information
on IBS suppliers
and consultants?

Policy: Q13: Which
Information Center can
Ketua Setiausaha Perbendaharaan, be contacted for
Bahagian Perolehan Kerajaan, queries?

Q1: What is IBS Score?

A structured and systematic Part 1: Structural
calculation method to systems (Max Score =

identify the total usage of 50 points)
IBS components in a
Part 2: Wall system
building project by referring (Max Score = 20
to CIS:18 2018 points)

PART 1 F Part 3: Other simplified
O construction solutions
50Σ[ ] (Max Score = 30 points)

PART 2 R
M
20Σ[ ] U

PART 3 L
S A

• Usage of IBS components that are prefabricated
and prepared off-site

• Utilization of standardized components based on
MS1064

• Repetition of structural layout

• Usage of other productivity enhancing solutions,
Building Information Modelling (BIM) and Modular
gridlines

Q2: Principles in calculating
IBS Score

Q3: How does a project A minimum of
being measured for IBS
implementation and what shall be achieved for
are the requirements to be a government
met for a project? project

Measured via
IBS Score
calculation

Q4: What measures shall be taken to ensure the
minimum 70 points is achieved?

PART 1 PART 2 PART 3
STRUCTURAL WALL SYSTEMS
SYSTEMS OTHER SIMPLIFIED
• Utilise more precast CONSTRUCTION
• Increase the usage and prefabricated SOLUTIONS
of precast panels in the
components instead construction • Utilise more
of cast in-situ standardised
concrete • Substitute common components,
brickwalls to repetitive structural
• Utilise prefabricated blockwork systems layouts, modular
roof trusses gridlines, and BIM
models

Q5: During Design Stage

The non-compliance of
architectural drawing with
modular system causing the
implementation of IBS system
PROBLEMS become ineffective.

What action can be taken?

OVERCOME

Good communication and
coordination among engineer,
designer and architect
throughout the design stage.

GOOD COMMUNICATION
AND COORDINATION

The concept of modular
coordination can be
applied successfully.

RESULT

Q6: What are the
improvement of the IBS
factor in CIS 18:2018
from CIS 18:2010?

Structural System; Wall System
Reduction in IBS factor (Revised factor) ; Allocation
of new IBS system for In-situ concrete with
permanent formwork
- To promote the reduction of reusable

formwork usage
- To reduce the usage of wet concrete at

construction site
- To reduce dependency of site workers (less

labour intensive)

Other Simplified Construction Solutions
Addition of other productivity enhancing solutions
in order to further promote IBS system
- To promote the usage of innovative products

such as prefab bathroom unit (PBU), prefab
staircases, BIM and modular gridlines in
drawing
- To encourage creativity and innovation in
engineering field
