MMC has been globally recognised as a promising solution for the current global social housing crisis, although persistent challenges remain in relation to limited early-stage design coordination and chronic design inconsistencies, which often cause costly post-design modifications. In response, digital twinning enabled through BIM has emerged as a compelling approach to tackle these challenges. BIM serves a transformative role in advancing sustainable social housing supply by integrating BIM with advanced smart technologies such as AR/VR, IoT, AI, and robotics. Nevertheless, significant constraints continue to impede a wide adoption of BIM due to technical capacity, organisational readiness, knowledge dissemination, and legal frameworks that support embracing BIM and associated smart technologies. Moreover, a notable knowledge gap persists in the application of BIM-enabled digital twinning across the entire project lifecycle of MMC projects, which may be addressed through the integration of Industry 5.0 principles with BIM, emphasising human-centricity, resilience, and sustainability as foundational pillars for future innovation.
