Industrialized Building System Evaluation Framework For Highway Construction In Malaysia

Abstract

Sustainability and Industrial Building System (IBS) closely linked each other due to the unique characteristics of IBS that help promote sustainability in construction. IBS is a construction technique in which components are manufactured in a controlled environment, transported, positioned and assembled into a structure with minimal additional site work. IBS promoted by CIDB which most of the implementation on the IBS only assessed and evaluated on the buildings. In the new highway project development, the Government through implementing agency, Malaysian Highway Authority (MHA) have set the requirement to the new highway project to achieve at least 20% of the IBS in the construction works and 70% of IBS’s component application in the structural works. Reviews of literature revealed that Malaysia is still lacking of a mechanism in determine the IBS’s component application in the structural works for highway. In view of this issue, this study is carried out to develop an IBS evaluation framework for structural works in highways construction. Also the existing level of IBS acceptance in the highway construction industry and IBS’s component used in the highways have been investigated and evaluated. The findings lead to establishment of the evaluation frameworks on the IBS’s components in the structural works for highway. The proposed of the evaluation framework enables the implementation on the IBS’s components in the structural works for highway more structured and organized towards enhancing the overall performance of highway construction in Malaysia.
