Abstract
The use of IBS (Industrialised Building System) has attracted a lot of countries like Singapore, Sweden, Germany, Japan and the United Kingdom. This system can replace the conventional building system which is labour oriented. However, since the first project of IBS in year 1964 till today, IBS in Malaysia is not well accepted by the construction parties because of failure to adequately deal with risks in the IBS projects. To address this matter, this study had identified the risks faced by contractor in IBS construction projects. The risk identification techniques used were brainstorming, analysis of journal and conference papers and discussion with practitioners and data were collected by a questionnaire survey on contractors. It was found that there are twelve major risks in construction using IBS which are; acts of God, change in work and defective design, changes in government regulation, contractor competence, delayed payment and resolving contractual issues, financial failure-any party, labour and equipment productivity, labour, equipment and material availability, quality of work, safety, site access/right of way and suppliers/manufacturers poor performance. Therefore, it is hoped that the finding of this research could assist Malaysian contractors in making risk management planning besides improving decisions making to achieve project.
Highlights
The construction industry is one of the most dynamic, risky, challenging and rewarding fields
This study presents the perceptions of Malaysian contractors towards IBS risks in housing construction in Malaysia since there is no concrete study about it in the past
The questionnaire design were undertaken in the phase consisted of literature review of past research focused on risks in construction and IBS housing project. 27 construction risks were compiled from previous similar studies conducted in the USA[7] and Hong Kong[1] and from an interview with experienced personnel involved in IBS projects it was reduced to 12 risks based on IBS project in Malaysia construction situation
Summary
The construction industry is one of the most dynamic, risky, challenging and rewarding fields. The IBS is an industrialised building system which all building components are mass produced either in factory or at site under strict quality control and minimal on site activities[16] It is an industrialisation essentially as an organisational process-continuity of production implying a steady flow of demand; standardisation; integration of the different stages of the whole production process; a high degree of organisation of work; mechanisation to replace human labour wherever possible; research and organised experimentation integrated with production. It can speed up construction process and with less labour on site and, if possible, at less cost and minimized effects of risk. Failure to adequately deal with uncertain, unpredictable and undesirable event has been shown to cause serious effects of risk that can be summarized as: chosen to use the IBS in their construction industries including the Malaysia government[15]
