The mainstream explanation of Building Information Modeling (BIM) in China focuses on using various relevant data from construction projects to create building models. These models digitally simulate the real information of buildings. Simply put, 3D models act as carriers of information, with the core emphasis on the data itself. This definition is relatively narrow and practical. Another interpretation is Building Information Management, which shifts the focus of BIM towards management, aiming to leverage BIM as a tool to transform management practices.
International software providers such as Bentley, Autodesk, Trimble, Graphisoft, and Dassault, alongside domestic vendors like Luban, Guanglian Da, and Swell, offer a wide range of BIM software, each with its own strengths. However, no single software can meet all the demands of the entire BIM implementation process. This gap highlights a fundamental challenge: BIM’s original intent is to integrate data and use big data to support management decisions. If information remains scattered, it cannot truly be considered BIM.
Without a comprehensive software solution, users must navigate the interaction between different software platforms. One approach is to adopt the IFC standard, currently the only available but imperfect solution. Another approach involves API-based secondary development, creating plugins within specific software. While many have explored this route, it still does not fully resolve the issues. Data loss during component conversion is a common problem; the real challenge is not knowing which components are lost, a frequent issue with current conversion plugins. Therefore, software solutions often fall short of expectations, and the high demands placed on BIM contribute to the perception that it is still in its early stages.
Stakeholders such as construction companies, survey and design firms, and supervision units each operate within their own closed loops, prioritizing their own interests. If the overall volume of the market remains unchanged, the distribution of benefits will inevitably involve mutual gains and losses. This situation raises an important question: who is BIM really serving? At present, the primary users of BIM are construction companies. BIM’s application within construction can be divided into two main areas: firstly, enabling managers to gain better insights into projects and improving management capabilities; secondly, facilitating accurate settlements with clients and helping construction teams secure fair compensation with clear evidence.
When will BIM move beyond its initial stage? The answer lies in addressing these two core challenges effectively. Regarding current BIM implementation, one common approach is for construction companies, represented by Chinese characters, to establish their own BIM centers. These centers primarily use Revit for secondary development, allowing them to manage BIM processes internally.
