Abstract
The Malaysian government has endorsed the use of an industrialized building system (IBS) in domestic projects. These have shifted the focus of the nation's construction industry towards mass production and modular products. A proper study on site selection criteria for new IBS precast manufacturing sites has now become essential. The preliminary study in this research determines the IBS precast manufacturing site selection criteria from literature reviews. Questionnaires pertaining to IBS acceptance and preference criteria were send to manufacturers, policymakers, academicians and contractors. The outcome analyses the respondents’ view towards 15 site selection criteria. The result from the ANOVA statistical test indicates that most respondents agreed with the selected criteria except political and regulation criteria, urban requirement criteria, and personal criteria. However, there is a significant difference within the opinions of the contractors and manufacturers sector. Likewise, the mean ranking analysis of criteria shows significant difference in their preferences. The ideal rank of criteria preferred by the correspondents are costs, transportation and optimum distance, land sites, resources and utilization, infrastructures, economy markets, labour, inter-industry linkage, environmental risk, competition, personal, population, capacity, political and regulatory, and urban criteria.
Highlights
In the first quarter of 2010, Malaysia’s economy achieved a growth of 10.1%
The trend of the Malaysian construction industry has moved from the traditional method to industrialized building system (IBS) manufacturing and the productivity have moved from project based to product based
This paper presents an outlook of four groups of respondents in the assessment of criteria for IBS precast manufacturing site selection
Summary
In the first quarter of 2010, Malaysia’s economy achieved a growth of 10.1%. Manufacturing and construction were the two major sectors, which showed an increase growth of 16.9% and 8.7% respectively (MITI 2010). The IBS Roadmap was approved by the Cabinet in October 2003 with the objective of providing guidelines for the establishment of an industrialized construction sector as well as the creation of an open construction system by 2010 The development of this roadmap was based on the “5M strategy” (machinery, manpower, material, measurement, and method), and it will be implemented gradually in governmental projects (CIDB 2003). In line with the determination of multiple site selection criteria for new IBS precast manufacturing, multicriteria decision-making (MCDM) is vital. It has been an important part of management sciences over the century (Farahani et al 2010). The outcome of the paper highlights the ranking of multiple site selection criteria for IBS manufacturing
