Description
Summary:Purpose - Labour usage represents one of the critical elements in the Malaysia construction industry due to severe shortage of local workers. This paper aims to present a construction performance comparison between conventional building systems and industrialised building systems (IBS).Design methodology approach - Data were obtained from 100 residential projects through a questionnaire survey in 2005. A total of 100 respondents participated in this study.Findings - Analysis of variance (ANOVA) results indicated that the actual labour productivity comparison between conventional building system and IBS was significantly different. Further, the comparison of crew size indicated that the conventional building system of 22 workers was significantly different from the IBS of 18 workers. Similarly, the cycle time of 17 days per house for conventional building system was found to be significantly different from the IBS of four days. However, the conventional building system was found to be insignificantly different from the IBS in term of structural construction cost.Originality value - The results acquired from this study could be used by project planners for estimating labour input, control costs and project scheduling. Additionally, they could be used to determine the most appropriate structural building system for executing a construction project at the conceptual stage.
