Although BIM technology is gaining increased attention from relevant departments and enterprises in China, its application and development remain in the early stages compared to Europe and the United States. Currently, less than 1% of engineering projects in China utilize BIM technology during the design phase. The use of BIM in domestic architectural design faces several key challenges:
1. Complex Modeling Demands Significant Time and Effort: While BIM technology offers clear advantages over traditional 2D CAD design, designers must invest considerable time and energy into building information models in addition to their creative and design tasks. When speed and efficiency are critical, many designers are reluctant or unwilling to adopt BIM design methods. To address this, companies need to implement incentive mechanisms or demonstrate that BIM can not only enhance quality but also reduce their workload. In this context, this article focuses on developing BIM-based functional modules such as automatic 3D structural component layout, collision detection, and automatic conflict resolution. These modules aim to optimize the design process, reduce the workload for designers working in 3D, and improve overall design efficiency.
2. Multiple Stakeholders, Diverse Software, and Complex Workflows Hinder Information Sharing: BIM product development is dominated by international companies such as Autodesk, Bentley, and Dassault, with Autodesk holding the largest market share. During the design phase, common products include the Revit series, Navisworks for construction simulation, Plant3D for pipeline design, and Inventor for equipment design. Different project participants often use different software based on their specific requirements, and these products serve distinct business functions. This diversity leads to varying data format requirements during model conversion, making it challenging to share information effectively without a unified data format. The adoption of standardized data exchange formats such as IFC, IFD, and IDM is essential to ensure BIM information can be shared throughout a building’s entire lifecycle. Before this can be achieved, creating and organizing BIM data and establishing corresponding information models are critical steps to guarantee efficient data exchange.
