Frequently Asked Questions

Industrialised Building System (IBS) is a construction method where components are manufactured in factory on in-situ in a controlled and monitored environment, transported and installed with minimum workforce. This system is widely used in developed countries.

There are 6 common types of IBS as follows:-

  1. Steel Frame System;
  2. Timber Frame System;
  3. Block Work System;
  4. Precast Concrete System;
  5. Formwork System; and
  6. Other Innovative System

IBS is widely accepted in the developed countries, IBS in Malaysia was first introduced in the Pekeliling Flats Projects in Kuala Lumpur. IBS helps to reduce foreign labour as well as to increase quality and shorten the completion time of construction work. In addition, the Government also intends to generate IBS component manufacturing industry which would be able to contribute to the national GDP.

  1. Higher quality products with minimum wastages due to factory-controlled prefabrication environment;
  2. Elimination the usage of timber formwork and great reduction of props through the usage of prefabricated elements or formwork system for site casting;
  3. Faster completion due to the introduction of prefabricated components replacing in-situ construction;
  4. Sturdy and sage work platforms provided by the prefabricated elements;
  5. Minimum labour usage as bricklaying and plastering work is no longer used;
  6. Less cost in overall construction budget due to all of the above.

To realise the Government’s aspiration to transform the Malaysian construction industry into a modern construction method, the IBS Centre was established in January 2007 as One-Stop-Centre especially in assisting IBS related issues involving Government’s projects.

The IBS centre main focused are: User, Product and Industry.

IBS Centre offers seven (7) professional training courses as follows:-

  1. Module IBS01: Introduction to IBS and Modular Coordination;
  2. Module IBS02: IBS Score Calculation and Submission;

IBS Centre does not offer such course instead, it is offered and conducted by the Construction Personnel and Contractor Development Sector of CIDB. You may contact them for any information regarding the courses or refer to CIDB website: For existing

The schedule for those courses can be referred via IBS Centre homepage at or directly from our office.

The component manufacturers need to register at the IBS Centre and verification process will be conducted. Upon completion of the verification and validation process, a report will be released. Certification will be issued in 1 month after the data of the released report. The registration form can be downloaded from IBS Centre website.

The supply of IBS component from the companies listed as IBS Manufacturers /Distributors /Suppliers or On-site Manufacturers attained IBS certified status only will be considered for Government projects.

IBS products manufactured locally shall undergo the verification process. For imported IBS products, the need to verify will be on case by case basis.

As of December 2010, more than 130 companies of suppliers and manufacturers are registered as IBS status manufacturers and the numbers are continuously increasing.

There are seven (7) IBS training modules offered by IBS Centre in which four (4) modules are compulsory namely IBS01, IBS02, IBS03 and one other optional module to be attended for being a competent IBS Consultant registered with IBS Centre, CIDB.

Any information with regards to IBS and related subject can be obtained from Sabah CIDB regional offices in Kota Kinabalu and Tawau while in Sarawak CIDB regional office in Kuching and Miri.

Normally for terrace houses, renovation job involves the rear and front portion of the unit. Knowing this, most developers will not use Precast Concrete System for both areas mentioned above. Before considering any renovation work please contact the developer / consultant to seek their advice.

IBS method of construction in this country consists of several types of common system. For the purpose of building a bungalow, there are several system considered suitable such as Block System, Steel Framing System, Timber Framing System or Precast Concrete System. It is very much dependant of the owner to choose what type of preferred system and available budget. In IBS Centre, four (4) types of full scale proto-type houses have been built using IBS method of construction for reference.

Yes, Makmal Kerja Raya which is under the purview of Construction Research Institute of Malaysia (CREAM) has the facilities to do testing. The laboratory is located next to the CIDB Convention Centre, Jalan Cheras, Kuala Lumpur.

The cost of IBS component is slightly higher than the cost of raw materials at construction site due the production of IBS components with standard and controlled production procedures in the factory. Overall construction costs of IBS are competitive if compared to the conventional method of construction. In other words, the reductions of constructions cost have been made by early completion, raw materials and site labours. Generally, as the quality assured, construction project with IBS is competitive compared to conventional method of construction.

Usually an architect is acted as lead consultant in the building construction project. The role of an architect is to coordinate the design and engineering aspect which also includes aesthetical value of the building. The architect is responsible to ensure practical building and meeting user needs. The design creativity and skill of an architect will ensure high aesthetical value and practical building product. In addition, an architect’s creativity in the manipulation of IBS method of construction provides effective role of an architect to produce high quality construction product other than concrete based components.

IBS Centre is One Stop Centre for industry players. IBS Centre provides supply chain database as reference to the industry. Accredited IBS Manufacturers / Suppliers shall be able to fulfil the current market demand. IBS Centre also carry out continuous efforts to increase the current IBS manufacturers with several programmes towards sustainable IBS manufacturers.

IBS method of construction requires proper and accurate planning from design stage towards the installation phase. Proper planning in each phases will avoid design changes. Among others, this is benefit of using IBS where accuracy of design process will eliminate additional cost.

IBS is not only about precast concrete instead there are many IBS construction method for you to consider. You may use Block System which is easier to transport or use Load Bearing Wall System for easy installation; timber frame and lightweight steel frame are also good options. There are other choices of IBS system which you can consider.

Usually, project developer of Superintendent Officer of the project shall be responsible to conduct the inspection and enforcement of on-going project.

The IBS scoring system was made accordingly to the following principles:-

  1. Usage of prefabricated and precast components;
  2. Application of standard components;
  3. Application of Modular Coordination (MC);
  4. Lowering labour dependency; and
  5. Repeatability.

The exemptions from using IBS method of construction based on the circular issued by the Treasury (SSP Bil. 7/2008) are as follows:-

  1. Projects below RM10 million;
  2. Renovation or refurbishment projects; and
  3. Remote project.

The end of IBS Roadmap 2003-2010 will be continued by the newly structured IBS Roadmap 2011-2015. It has been approved by the Cabinet on 9 July 2010. In order to continue the Government commitment towards modernization of the construction industry and stakeholders needs the IBS Roadmap 2011-2015 have been reviewed and restructured under the purview of strengthening Government machinery to accelerate private sector involvement in total. The main focus of IBS Roadmap 2011-2015 are as follows:-

  1. To sustain the existing momentum of 70% IBS content for public sector building projects through to 2015; and
  2. To increase the existing IBS content to 55% for private sector building projects by 2015.


These goals will be achieved through the implementation of four (4) work streams:-

  1. Work stream 1: Institutional Strengthening;

To ensure that the Government unwavered commitment towards IBS, policy objective driven to execute and drive changes for the modernization of construction industry.


  1. Work stream 2: Focusing on User;

This work stream will address the need for a ready pool of both professional and skilled workers who are practising IBS and reduce reliance on foreign workers.


  1. Work stream 3: Focusing on Product;

This work stream will concentrates on the IBS product itself, including the standardisation issue.


  1. Work stream 4: Focusing on Industry.

This work stream is to energise the IBS component manufacturing industry, i.e. to ensure it remains innovative and supportive, with accreditation standards for the products and trained workers. The work stream will also focus on time delivery of projects.

IBS content is the percentage of scoring achieved in the project through the calculation system – Manual for IBS Content Scoring System (CIS 18). The systematic calculation of IBS components will identify the percentage of IBS content in the project. The manual for IBS content scoring system (IBS Score) issued by CIDB Malaysia is a guide to calculate the scoring or percentage of IBS usage in a development project. A higher IBS score is a reflection of a higher reduction of a on-site labour, lower wastage, less site materials, cleaner environment, better quality, safer construction sites, faster project completion as well as lower total construction costs.


The breakdowns of scoring are as follows:

Structural System                    : 50%

Wall System                              : 20%

Other Simplified Solutions    : 30%


The manual can be obtained from CIDB office or download at IBS Centre website

The IBS Score of the project shall be calculated by multiplying the percentage of construction area of the respective building (out of total construction area of project) with the IBS Score of the individual building. (Please refer detail in the Manual for IBS Content Scoring System – CIS 18).

Remote project shall be defined where the project is hardly accessible through roadways for the delivery of IBS components. The exemption to use IBS in the Government project shall only approved by the Director General of Works Department.

Generally, the usage of IBS will give impact to the environment indirectly. The shorten completion time of project, less wastages and safe condition of construction will contributes to less carbon emission and safe environment. In addition, to increase the development of green building, various programs have been structured to increase the development of innovative product in green technology as outlined in the IBS Roadmap 2011-2015.
