Case 5
Cities use Digital Twins to effectively implement BIM and GIS technologies, thereby improving the quality of life of their citizens.
Local governments around the world are looking for ways to work together more effectively. work in innovative digital initiatives. They get a clear picture of what's going on by simulating real situations, optimizing systems and processes, and monitoring asset performance and health. As a result, public safety improves, and the city's infrastructure becomes smarter and more resilient.

Chengdu, the capital of China's Sichuan province, is implementing a CNY 1.38 billion road reconstruction project in Shanbanquo. The project includes the construction of 4.3 km of roads, as well as bridges, tunnels, a pedestrian underpass, pipelines and ancillary works. The design of the main road should be designed for vehicles moving at a speed of 60 km/h, and auxiliary roads should be able to provide a speed of 40 km/h. The design team encountered a number of design challenges, including lack of space between the top and bottom of the roadway and the driveways.
It was also necessary to determine the horizontal distances between the pile foundations, the widened viaduct and the boundary conditions, as well as to provide for a power tunnel, two metro stations and three sections of metro line No. for low speed traffic at the entrance to commercial enterprises on both sides of the road. Finally, the design team had to consider the design and construction of a safe pedestrian walkway system along green space and parks adjacent to high traffic areas.
