Bridging the LOD 100–150 Gap: A Digital Innovation Framework Integrating Serious Gaming and CPBL for Systemic BIM-MEP Management

In the Industry 4.0 era, the AECO sector faces a strategic challenge in integrating MEP systems during early design stages, where a lack of "Design for Maintainability" contributes to building defect rates of up to 28%. 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 LOD 100–150. Using a mixed-methods design (n=25), the curriculum employed a "Mirror Mapping" mechanism, translating game physics (e.g., Redstone and water mechanics) into real-world electrical and plumbing logic. While students achieved 93% in management competency and nearly 100% accuracy in pipeline logic among upper-level cohorts, a significant "Symbolic Transformation Gap" persisted, with performance in system analogy (80%) lagging behind procedural mastery. The findings validate the framework as a potent tool for spatial externalization, yet emphasize the necessity of "bridging activities" and Digital Twin linkages to ensure effective knowledge transfer from simulated environments to professional AECO practice.
