Located in the high-altitude alpine region of Tibet, this hydro-complex for a water conservancy initiative is focused on irrigation and power generation, improving urban and rural water supply and the regional water ecological environment. Knowing the importance of subsurface findings, the survey and design team faced challenging terrain and extreme environmental conditions, that traditional survey methods could not accommodate. They explored digital data acquisition and 3D modeling of geological data but found that many software products lacked integration and the ability to maximize data potential.They selected Bentley’s open, vendor-neutral ecosystem to produce solutions that would digitalize the production process. Using ContextCapture to process data for geological visibility and ProjectWise for multidiscipline collaboration, new reusability of data for smart engineering evolved. The solution saved CNY 400,000 in survey costs and over 50% in survey time, improving data accuracy by over 10% and work efficiency by over 15%. Establishing a digital twin enhanced project management by 10% and sets an industry benchmark.
