ABSTRACT
Industrialised Building System (IBS) is a construction method where prefabricated components are used instead of cast on site approach. It has more to offer compared to the conventional method. Among these advantages are shorter construction period, reduced overall cost, improved labour productivity, better site management and reduction in waste generation. Developments of housing units are needed due to the growing population and increased demand for housing. This study was with the aim of investigating the perception of professionals on the prospects, challenges, and strategies for improving IBS usage in housing development, specifically in Abuja. The method adopted was purposive sampling technique where questionnaire were distributed to 100 built environment professionals, handling housing projects. Data obtained from the 80 questionnaire returned were analysed using SPSS software. The results revealed that majority of the professionals handling housing projects in Abuja are practicing traditional cast in – situ method and IBS application is considered for few projects. The challenges of IBS application according to the respondents are; insufficient IBS manufacturer, unfamiliarity due to resistance to change, enormous capital cost and lack of government interest. In order to overcome these barriers, majority of the respondents agreed that improving the educational curriculum, adopting intensive training for the related professionals, usage of IBS in government housing projects, government support with startup capital, and promotion of market acceptance of IBS housing units, would help in improving IBS adoption in Abuja housing development. The implication of this study is that Government support and increase awareness on the prospects of IBS would improve the usage of IBS in housing development.
