Covering 3.8 hectares in Qinghai, Deerwen’s 110-kilovolt substation will relieve the long-term power shortage in six towns, improving living conditions and promoting economic development. Located in a high-altitude, mountainous area with complex terrain, the multidiscipline project presented site, technical, and coordination challenges. The project team realized that they needed an integrated design and BIM solution to optimize project delivery.The team selected Bentley’s open applications, facilitating collaborative design workflows and real-time rendering to achieve refined, coordinated design of the substation and facilities amid the natural surroundings. They identified and resolved 657 collisions and shortened the design period by 40 days, improving design quality and construction efficiency by 35%. Developing a precise design saved 30% in material quantities and avoided resource waste to reduce the project’s carbon footprint. The 3D models and digitized data provide the basis for intelligent digital plant operations and maintenance, while the successful project delivery drives digitalization, setting a benchmark for power industry projects in China.
