Hydropower projects face massive, complex, and high-demand scenarios—from basin-level overviews to facility-level details, covering above-ground, underground, and long linear tunnels/pipelines, across the entire project lifecycle.Our platform delivers full-precision BIM integration and ultra-large-scale scene support, enabling cross-scale digital twins and solving challenges like geometric distortion in long linear models. It integrates engineering data (progress, quality, safety) with IoT real-time monitoring, keeping digital twins and physical assets dynamically synchronized. Design: Collaborative and delivery platforms;Construction: BIM+GIS decision-making and “Four Forecasts” scenarios;Operation: Basin simulation, water resource optimization, and dam safety monitoring. With a unified, live digital twin foundation, our solution provides core capabilities for engineering and basin-level digital twin projects, turning complex hydropower operations into a manageable, data-driven ecosystem.
