Digital Transformation in Early-Stage MEP Coordination: A Serious Gaming Framework for Sustainable Design and Maintainability at LOD 100–150

In the Industry 4.0 era, the Architecture, Engineering, Construction, and Operation (AECO) sector faces a strategic challenge in integrating Mechanical, Electrical, and Plumbing (MEP) systems during early design stages, where a lack of “Design for Maintainability” contributes to building defect rates of up to 28%. These failures not only incur significant resource waste but also undermine long-term building sustainability. This study evaluates a digital innovation framework synthesizing Serious Games and Cooperative Problem-Based Learning (CPBL) via Minecraft to foster systemic thinking and spatial reservation logic at Level of Development (LOD) 100–150 as a catalyst for digital transformation. Utilizing a mixed-methods design (n = 25), the curriculum employed a “Mirror Mapping” mechanism, translating game physics into real-world electrical and plumbing logic. While results showed 93% management competency, a significant 13% “Symbolic Transformation Gap (STG)” (80% in system analogy) persisted, indicating that symbolic fluency does not automatically yield professional engineering reasoning. These findings validate the framework’s potential for spatial externalization and emphasize the necessity of “bridging activities” and Digital Twin linkages to optimize building lifecycle performance and reduce carbon footprints, ultimately achieving sustainable building goals.
