BIM software primarily involves several major platforms: Autodesk, Bentley, Dassault Systèmes, and various domestic solutions. From a broader perspective, BIM software is more widely adopted internationally than domestically. There is a greater focus on design applications than on management ones, and more software options cater to building projects compared to roads and bridges. Specifically, in highway engineering, Autodesk and Bentley BIM solutions are the most commonly selected.
Autodesk’s Civil 3D and Revit focus primarily on the design phase. Navisworks supports construction simulation and clash detection, while InfraWorks provides effective rendering capabilities. Bentley’s PowerCivil, tailored for China, also targets the design process and enables rendering via LumenRT to create visual animations.
Comparing these software products in detail reveals some key differences. PowerCivil uses the standardized DGN file format, which allows seamless use across different Bentley products. In contrast, although Civil 3D uses the DWG format, files cannot be directly recognized by CAD upon opening and require format conversion, adding extra steps and extending processing time. This increases workflow complexity and can hinder efficiency.
Regarding complex tunnel design, Civil 3D employs an assembly-based approach, while PowerCivil uses cross-sectional design methods. The former tends to be quicker and easier for completing corresponding designs. Throughout the entire highway lifecycle, Autodesk and Bentley products continue to evolve through ongoing updates and improvements, but none are yet fully perfected. Each software package has its strengths as well as limitations.
From the perspective of transportation design institutes in China, BIM technology application in highway engineering remains at the “BIM flipping” stage. It is viewed as an effective alternative method shaped by real-world constraints and tailored to China’s national conditions. Problem-solving remains the core focus. Consequently, many Chinese design institutes have developed secondary software tools based on existing BIM platforms, such as the “Chengtage BIM Series,” to better support their workflows.
Overall, at every development stage, it is crucial to select software products that scientifically match the requirements of each project. Achieving an optimal alignment between software capabilities and project needs ensures that BIM tools deliver their full potential and support smooth project progression.
