Impacts of Implementation of IBS Score Regulations of CIDB on the Concrete Volumes Required for Building Projects in Malaysia

Improvement of construction industry will contribute to the economy of Malaysia because it is one of the five sectors used to calculate the national GDP. This fact is encouraging the Construction Industry Development Board (CIDB) of Malaysia to prepare many development plans like Roadmap 2003-2010, CIMP 2006-2015, and Roadmap 2011-2015. Adoption of the Industrialized Building System (IBS) is the step stone for all these plans. CIDB has created an indicator to assess the degree on industrialization for applied building system; IBS score. Furthermore, CIDB has specified the minimum values of this score for the building projects of government and private sector. This paper discusses the effects of adjusting these values on the structural design of an office building. The CIDB method of calculating the IBS score, the moment distribution method of structural analysis and BS8110 code of design will be used to analyze the selected case study.
