Abstract
This study examines the adoption, benefits, challenges, risks and preventive measures linked to Modular Integrated Construction (MiC) in the South Africa's building sector, with a focus in South Africa. MiC, an innovative construction method that integrates off-site prefabrication with on-site assembly, offers notable advantages in efficiency, sustainability, and project delivery. However, despite its potential, the global adoption of MiC remains limited, with particularly low uptake in developing countries. Existing research has predominantly concentrated on high-rise modular buildings, durability, lean construction principles, and general performance, leaving a gap in comprehensive studies addressing the technical aspects of MiC implementation. Using a quantitative approach, this study employed a survey to gather information from industry experts. The results were analyzed using SPSS version 29.0.2.0, identified critical challenges, including risk management, logistics, and manufacturing processes. Hydrothermal and structural risks posed significant concerns, while planning and design risks, supply chain risks, and financial risks were identified as lesser.
To address these challenges, the study recommends implementing robust risk assessment frameworks, improving stakeholder coordination, strengthening supply chain management, delivering targeted training programs, and enforcing stringent quality control measures during manufacturing and assembly. The study was limited by time constraints, a low response rate, and a reduced sample size, compounded by the economic challenges facing South Africa’s construction industry during the pandemic, which affected professionals’ availability and willingness to participate. The findings underscore MiC’s transformative potential to revolutionize South Africa's construction industry by improving efficiency and sustainability. However, overcoming current barriers will require strategic planning, enhanced risk management practices, and collaboration among industry stakeholders. Resolving these challenges is crucial to fully harnessing the potential of Modular Integrated Construction and fostering innovation within the construction industry. By recognizing and minimizing risks, enhancing regulatory frameworks, and integrating cutting-edge technologies, the South African construction sector can boost efficiency, sustainability, and international competitiveness.
