Inhibitors to the Adoption of Building Information Modelling in Modular Construction: A Case Study of the Nigerian Construction Industry

Abstract

Building information modelling (BIM) adoption transforms how construction projects are delivered. Modular construction (MC) is a modern construction method that drives continuous improvement and value addition globally. BIM and MC offer enormous benefits in enhancing project delivery and attaining sustainable construction. This is a major driving force causing the drift from traditional methods to a more digitised approach anchored on technology. Despite these benefits, the level of sophistication in project delivery and the application of these innovative methodologies are low and housing construction projects are delivered with poor performance outcomes in developing countries like Nigeria. This study assessed the inhibitors to the use of BIM in driving MC and the measures for improving the adoption of BIM in MC project deliveries in Nigeria. A well-structured quantitative questionnaire was administered to construction experts using Snowball sampling techniques via electronic means to collect data. With a response rate of 70% and a reliability index of above 0.80, the collected data were analysed using frequencies, percentages and mean item scores. It was found that the level of BIM and MC was high, but BIM adoption in MC was low. The inhibitors to this low adoption level are the high cost of investment in hardware and software, the comfort with the existing methods and resistance to change, the lack of management support, the complexity of BIM software, the lack of interest in sharing information among stakeholders, the problems with collaboration and the legal issues with multiple designs and fabrication. It is recommended that collaboration between construction and technology firms be encouraged to improve BIM application in MC for better productivity and project outcomes. The government should support the use of modern methodologies in the delivery of projects to help improve infrastructure provision, value addition and citizens’ well-being.
