Research on Power Engineering Project Management Optimization Based on BIM Technology

To address critical challenges in power engineering project management—including complex construction site environments, resource allocation inefficiencies caused by isolated asset operation data, and delayed safety risk response—this study proposes a BIM-based full lifecycle management optimization approach. A data integration platform centered on BIM models was established, utilizing nested family architectures and metadata templates to integrate multi-source heterogeneous data with information completeness metrics (≥80% compliance). By integrating BIM+GIS technologies, a digital engineering terrain sandbox (centimeter-level resolution) was developed to enable visualized earthwork balance simulations and dynamic resource allocation. A dynamic risk coefficient model was constructed using displacement monitoring data from BIM components, forming a real-time safety risk early-warning closed-loop control system. Case validation demonstrated that in a 500kV substation project (8.5 hectares), optimized digital sandbox reduced secondary earthwork transportation volume to 105m3—over 93% lower than traditional methods (1,400–1,600m3). Pit displacement monitoring triggered 8 yellow/red alerts, all resolved within 30 minutes, achieving precise construction resource management and proactive safety risk monitoring.
