Construction Contract/ Expenditure in 2009

Malaysian construction industry provides job opportunities  for 800,000 people. 69% registered as in June 2007 are foreign workers.

Conventional construction method commonly practice in Malaysia intensively reliance on unskilled foreign labour and time consuming.

Government had shown their effort by bringing up IBS Roadmap as a direction of implementation

A construction technique in which components are manufactured in a controlled environment (on or offsite), transported, positioned and assembled into a structure with minimal additional site works.

Institutional Strengthening

*Recommendation 2 encompasses 6 major actions

To ensure that by using IBS, completion time of a building is speedier, more predictable and well-managed.

To have a ready pool of competent IBS professionals and workers throughout the entire project life-cycle: from design, manufacture, build to maintain.

To create a financially sustainable IBS industry that balances user affordability and manufacturer viability

Good quality designs, components and buildings are the desired outcome of IBS. Aesthetics should be promoted through innovation.

MISSION: TO PROVIDE A QUALITY, EFFICIENT, COMPETENT & SUSTAINABLE IBS INDUSTRY THAT CONTRIBUTES TO THE COMPETITIVENESS OF MALAYSIA’S CONSTRUCTION SECTOR

Policy objectives are the high level intended outcomes of implementing IBS. To remain focused, it was narrowed down to four policy objectives i.e. quality, efficient, competent and sustainable. A sustainable IBS industry will contribute to the competitiveness of the construction industry.

The importance of IBS was emphasised in the Construction Industry Master Plan (“CIMP”) in 2006. Introduction of new construction methods such as IBS was under Strategic Thrust #5. All the seven strategic thrusts are expected to work in a holistic manner to leap frog the development of the construction industry. According to the CIMP, manpower development, research on materials, monetary (economic and financial), management processes and promotions are required to increase the usage of IBS.

IBS Track for the Public Sector

For the public sector who has already taken the firm stance to implement IBS in its Projects, this new Roadmap aims to raise the existing IBS score from 70% in 2010 to 80% by 2015 for GoM building projects above the value of

RM10million

Private sector  IBS Track for the Public Sector

The public sector cannot dictate the private sector to adopt IBS. Neither can the private sector be left to adopt IBS at its own pace. IBS should be carried out in the spirit of public-private-partnership (“PPP”). For the private sector, this new Roadmap aims to attain an average IBS score of 50% by 2015. This goal can be

further validated at the point of launch of the new Roadmap.

Type 3 Steel Framing SystemsSteel beams and columns, portal frames, roof trusses etc

Type 4 Prefabricated Timber Framing SystemsTimber frames, roof trusses etc

Type 5 Block Work Systems

Under the Open Building System concept, a building is made up of a series of systems, sub-systems and groups of input components. A crucial objective of moving towards an open building system is the inter-changeability factor. An open system ensures that components or sub-systems are interchangeable and easily replaceable.

Incentives for the Adoption of IBS for Private Sector

Note : 1. This exemption from levy only applies to housing project with minimum IBS Score of 50% 2. Effective 1st January 20073. Calculation per guidance on IBS Score calculation in “Manual for IBS Content Scoring

System (IBS Score)”4. Levy is imposed on construction works having a contract sum of above RM500,0005. Any construction works of low cost, medium low cost and medium cost housing projects

are exempted from levy effective 1 Feb 2005

If IBS score >50%, then levy exemption= 0.125% x project value

Potential Reduction and Cost Saving in IBS (CIB, 2010)

Essential IBS Mass – production ‐ The investment in equipment, human recourses, and facilities associated with an industrialisation can be justified economically only when large production volume is observed. 

Standardisation ‐ All components need to be standardised for production. Such standardisation of space and elements need prescribing tolerances at different construction stages such as manufactured tolerances, setting out tolerances, and erection tolerances.

Relation between unit cost and unit repetition (Gibb, 1999)

Essential IBS Labour specialisation ‐ Large production output and standardisation of precast elements allow a high degree of labour. specialisation with the production process. The process can be subdivided into a large number of small homogenous tasks.

Good organisation and planning ‐ High production volume, specialisation of work, and centralisation of production requires a efficient and experiences organisation capable of a high levelof planning, organising, coordination and control function with respect to production and distribution of the products

Essential IBS Integration ‐ In order to obtain an optimal result, a high degree of coordination must exist between various relevant parties such as designer, manufacturer, owner, and contractor.

Transportation cost ‐ It is found that casting of large‐panel system can reduce labour cost up to 30 percent. However, these cost savings are partially offset by the transportation costs.

IBS SCORE

IBS Content Scoring System (IBS Score) is a systematic and structured assessment system that can be used to measure the usage of IBS in a consistent way.

PRINCIPLES OF IBS SCORE

• the use of prefabricated and precast concrete components

•Off site production of components

•The use of standardised components

•Repeatability

•Design using Modular Coordination concept

THE IBS CONTENT SCORING SYSTEM (IBS SCORE)

Maximum IBS is 100 points made up of the following components:

Part 1 – Structural Systems (maximum score is 50 points)

Part 2 – Wall Systems (maximum score is 30 points

Part 3 – Other Simplified Construction Solutions ( maximum score is 20 points)
