Modelling the drivers of Modular Construction Adoption: A hybrid interpretive and predictive approach

Modular Construction (MC) is increasingly promoted in Australia as a pathway toward more sustainable and efficient building delivery; however, its adoption remains limited due to an incomplete understanding of the factors that drive implementation. This study investigates the key drivers influencing MC uptake through a mixed-method approach integrating qualitative insights with quantitative modelling. Semi-structured interviews with industry professionals identified 79 drivers, which were prioritized using statistical analysis and Pareto evaluation to determine the most influential factors. Structural modelling revealed clear hierarchical relationships among drivers, while predictive analysis validated their relative importance. Results show that social, technological, and supply chain considerations exert the strongest influence on MC adoption, extending beyond traditional economic-focused decision frameworks. These findings indicate that MC uptake is shaped by broader socio-technical conditions, including housing demand, digital capability, and coordinated production networks. The proposed integrated analytical framework provides a systematic basis for prioritizing interventions and supports policymakers and industry stakeholders in accelerating MC implementation within the Australian construction sector.
