BIM-Driven Collaborative Framework for Prefabricated Decoration Lifecycle Optimization

Prefabricated construction in China has faced integration challenges in integrating structural and decorative design, resulting in information silos and delays in progress and industrialization. This study introduced a Building Information Modeling (BIM)-driven collaborative framework to synchronize cross-disciplinary data across the stages of design, production, and assembly. The framework integrated parametric component libraries, semantic mapping, and construction sequencing simulation, with a closed-loop feedback mechanism for lifecycle model updates. Pilot testing in three projects revealed 32% higher design accuracy, 27% increased component reuse, and 41% faster on-site coordination. Factory prefabrication of integrated components reduced wet work by 58% and occupational hazards by 43%. The framework's universality was validated through theoretical and practical analysis, with recommendations for upgrading industry standards. Findings provided a policy reference for establishing digital evaluation systems in prefabricated decoration, thereby offering potential to accelerate China's transition to more sustainable construction methods.
