Liaoning Water also used OpenRoads’ linear engineering capabilities to design the rockfill dam section. It produced parameterized templates, assigned the cross-sections with the correct control conditions, applied the terrain boundary conditions, and generated a 3D model. This functionality enabled the project team to view any cross-section of the dam and to automatically deliver accurate quantities to create a higher-quality design. To design the extremely complicated concrete dam and its electromechanical system, the team combined multiple engineering disciplines with 3D modeling. Because this portion of the dam required hydraulic machinery and engineering as well as electricity and a metal structure, multiple engineering disciplines were implemented. Integrating Bentley software using a connected data environment enabled clash detection in OpenBuildings to pinpoint miscalculations and oversights. “Through 3D digital modeling, the complex
electromechanical system is more intuitive and dynamic,” Yixin said. “The automatic collision detection system lists the collision positions of electromechanical equipment in the form, which effectively eliminates the occurrence of errors, omissions, collisions, and defects and improves the quality of the design.” OpenBuildings facilitated module-by-module design of the concrete dam’s many odd-shaped structures with prefabricated beams, slabs, columns, doors, and windows. This capability saved time by allowing the design team to compare various options. Additionally, OpenBuildings’ generation of quantity statistics for building elements and hydraulic components removed human-error involved in traditional engineering calculations.
Digital twin Liaoning Water achieved technological innovation
using BIM software by combining the axial and side views of the 3D model with 2D drawings for a more comprehensive and straightforward design for the construction team. By using Bentley applications, the team improved design efficiency by 40% to deliver the engineering design two weeks earlier than anticipated. The BIM applications reduced design error by 90%, minimizing design changes during construction and accelerating the digital handover of construction progress to the client. By accurately calculating the project’s cost in the design stage, Liaoning Water lowered the overall project investment. It leveraged BIM technology to deliver a digital twin that provides support on the full lifecycle of the dam, including management during construction, operations, and maintenance. Upon completion, the Dongtaizi Reservoir will
mitigate flood risk and supply water to much needed areas within the river basin. Additionally, the precise design of the ecological fishway will restore fish migration and reduce the reservoir’s overall environmental impact. With this innovative design, Liaoning Water is the provincial leader in using BIM software for water conservancy projects. It is using this project as the foundation for the application of BIM software on other infrastructure endeavors and have already implemented corporate 3D collaborative design standards for the company and trained personnel. ●
