Project Summary

    • ADVANCING MIXED REALITY WORKFLOWS - Liaoning Water Conservancy and Hydropower Survey and Design Research Institute Co., Ltd.

Resolving A Water Supply Shortage

The Chaoyang underground pumping station aims to pressurize water flow to resolve water shortages and promote economic development and ecological improvements in the cities of Chaoyang and Beipao in Liaoning province. Reaching a maximum daily water supply of 440,800 tons, the facility will improve water distribution to 1.5 million area residents. The CNY 82 million project features numerous aboveground and underground structures, including an underground power plant, nine pumps, a water supply tunnel, a substation, and aboveground management infrastructure. Liaoning Water Conservancy and Hydropower Survey and Design Research Institute was tasked with designing the entire plant and faced technical, engineering, and coordination challenges amid a tight timeline.

Facing Complex Site Conditions and Coordination Challenges

Located in the valley along the Daling River between low mountains and hills, the project presented complex geological conditions and a narrow footprint, requiring careful consideration of the layout. The site also featured permanent underground functional caverns, including a ventilation corridor, a drainage corridor, and a traffic hole, that had to be avoided when planning the tunnel line and configuring connections between the underground and aboveground buildings. Faced with these site and structural challenges, compounded by coordinating multiple disciplines on a short design cycle, the institute realized that traditional 2D design would not suffice as it would negatively impact construction and investment. They wanted to establish digital workflows in a connected data environment and implement lifecycle 3D collaborative design. To achieve this digitalization, they needed integrated BIM and reality modeling technology.

Bentley Applications Provide Mixed-reality Solution

The institute selected MicroStation and ProjectWise for coordinated modeling and information sharing among the 13 disciplines. They used drones and ContextCapture to collect data and images, then they generated a reality model of the 1.2-square-kilimeter project area. By integrating OpenRoads technology, they developed a 3D geological model for a power plant buried 75 meters deep, and used the collision detection features in Navigator and OpenBuildings Designer to avoid clashes with the caverns, optimizing equipment arrangement in the narrow space. Through animated visualization using LumenRT, they identified errors early in the design process, improving design quality. With Bentley’s integrated technology applications, they streamlined design, performed construction simulation, and established 3D mixed-reality solutions that can be extended into operations and maintenance.

Advanced Digital Workflows Drive Savings

Compared to traditional design, using Bentley’s modeling and visualization applications for collaborative 3D design on the project increased design efficiency by 40% and reduced design errors by 95%. Working in a connected data environment using ProjectWise’s streamlined coordination and communication capabilities among the varied disciplines shortened the design cycle by 20 days. By performing collision detection and construction simulation, they saved CNY 10 million in costs. Integrating BIM, reality modeling, and virtual reality technology, the institute clearly and intuitively expressed design intent and achieved digital deliverables, providing a solid foundation for construction, management, and operations. Based on the success of this project, they have taken the lead to promote the application of Bentley’s advanced digital workflows for future projects within the water conservancy industry.
