Project

Located amid a dense road network in Shenzhen, Guangdong, China, the JiHe Expressway is undergoing a CNY 45 million reconstruction and extension. The expressway connects the surrounding area with the Bao’an International Airport, linking with over six other expressways in the area. CCCC First Highway Consultants Company was tasked with improving coordination and management while optimizing design. The project involved multiple engineering disciplines and presented site and design challenges. The team soon realized that, with a project of this size and scale, it would need to advance its work practices.

Solution

To overcome these challenges, CCCC began by implementing 3D modeling technology. The team began by using unmanned aerial vehicles (UAVs) to capture images, creating a reality model along the 43-kilometer line. The team also used this data to create BIM models of nearby roads, bridges, and landscaping. To help design large-scale and complex bridges, the team used parametric modeling and design, saving significant time by avoiding remodeling. Dynamic comparative modeling analysis helped the team compare the current environment with the design scheme, discovering issues in advance and reducing later modifications. The team also simulated driver scenarios during construction, determining a traffic safety scheme that sped up project approval and delivery while improving the design quality.
