A Study of Factors Affecting the Use of Industrialized Building System (IBS) Construction in Sabah

Abstract

The Industrialized Building System (IBS) has been introduced in Malaysia since the early 1960s, offering numerous advantages. This study aims to investigate the factors influencing the implementation of IBS in the construction industry in Sabah. A quantitative research approach was adopted, involving a sample of respondents registered with the Construction Industry Development Board (CIDB) who are actively engaged in IBS-related projects. The study focused on four key constructs: perception (P), knowledge (G), skills (K), and technology (N) in relation to the utilisation of the IBS system. A total of 182 participants, representing both government agencies and private sector entities, contributed to this study. Findings related to the knowledge construct revealed a strong consensus among respondents, indicating that individuals involved in IBS possess relevant knowledge and experience, with mean scores ranging from 4.19 to 4.40. However, concerns emerged regarding the skills dimension, where mean values ranged between 3.48 and 4.01. This suggests a degree of uncertainty or lack of confidence among respondents regarding the skill levels of personnel engaged in IBS. In terms of technology, the perception of IBS safety appeared to be a critical issue, with a relatively low mean score of 3.81. This perception may stem from the lighter structural components of IBS compared to conventional systems, potentially leading to misconceptions about its structural integrity. Overall, the insights derived from this study are significant for policymakers and stakeholders in the construction sector. The findings underscore the need for targeted strategies to enhance awareness, provide training, and promote the advantages of IBS—particularly in advancing its adoption within construction projects in Sabah.
