Critical policy drivers for Modular integrated Construction projects in Hong Kong

Given the increased importance of identifying the critical Policy Driving Forces (PDFs) to uptake Modular integrated Construction (MiC) practices in Hong Kong (HK), this study aims to identify and examine the critical PDFs associated with MiC projects in HK from the perspective of industry experts. After drawing on the plentiful relevant literature and conducting a pilot study, an expert opinion survey was conducted to gather the necessary data for this study. The collected data were analysed using relevant significance analysis and factor analysis to identify critical PDFs and appropriate groupings. The results revealed 23 critical PDFs under seven critical components in three stages of the MiC process. Regulative PDFs show the highest criticality for up-taking the MiC in the initiation and planning and design phases, while Greater Bay Area development PDFs are critical in the construction phase. The PDF related to the COVID-19 pandemic is the only critical PDF that appeared in all three stages. As the first study that explores PDFs for MiC uptake throughout all project phases, this study contributes substantially to theory and practice while better informing policymakers on how to initiate MiC-related policies to boost MiC practice in HK, where MiC is achieving greater prominence in application.
