| Summary: | The use of industrialised building system (IBS) has attracted many countries like
Singapore, Sweden, Germany, and Japan. This system can replace the conventional
building system that uses labour intensive force. However, although this system has
been used since 1964, its acceptance in Malaysia among constructors is not
satisfactory due to its failure in managing the construction system risks. Therefore in
order to address this issue, this study has identified risks faced by developers in
housing projects that use industrialised building system. The study also identifies
highly risked construction stages, determines risk allocation for sources of risk, and
proposes a computer program for the risk management. The techniques to identify
risks being used in this study are through analysis of past research publications like
journal, conference and discussion with parties involves in construction industry.
Data is compiled through questionnaires that are distributed and collected from
housing developers. The data is then analysed using statistical techniques like Chi-
Square Test and Pearson Correlation Coefficient. It is found that there are twenty
eight sources of risk that contribute to six types of risk in construction project. The
top five sources of risk are inexperienced contractor in IBS project, complexity in design, contractor performance failure, inappropriate estimate of construction cost,
and variety of design. Based on four stages of construction which are the initial
stage, tendering stage, procurement stage and implementing stage; initial stage
contributes to the highest risk in industrialized building system. The problem of
quality, poor productivity, defective materials, labour disputes and loss or delay due
to resources availability are on contractors’ shoulder. The building owners are
responsible on variation of work, sales and marketing, and deficiencies in
specification and drawing. The result of this study reveals that there is no relation
between types of industrialized building system being used and types of risk. Three
categories of risk which are financial risk, construction risk and design risk are
interrelated with each other. A tentative risk register tool produced in this study is
based on computer application. It may help developers to identify sources of risk,
evaluate and manage the identified risks as part of decision making. In conclusion, it
is hoped that this study could help developers in making risk management planning
besides improving decision making and achieving project objectives. |
