Constructability Factors in the Malaysian Construction Industry

Advances have been made in the theory and implementation of constructability in many developed countries such as the United States, United Kingdom and Australia. This is not observed in the Malaysian construction industry. This research aimed to narrow this gap. The first objective of this study is to establish statistical models to describe constructability implementation in the Malaysian construction industry so that an insight on the factors contributing to the constructability implementation can be established. The second objective is to evaluate the independent factors affecting constructability implementation in the Malaysian construction industry. The research findings were based on an industry wide questionnaire survey and four case studies: two highways projects, a cable stayed bridge and a sport complex. These case studies underpinned the results of the survey. A series of logistic predictive models were developed to assist managers in predicting the probabilities of successful implementation of the constructability concepts in their organizations, based on the estimates and the odds ratios of the independent factors. This provides a quantitative approach to constructability implementation in the Malaysian construction industry. The study reveals that five out of the eight examined factors significantly (p
