BIM technology is inherently complex, largely because it relies on computer technology. Building Information Modeling (BIM) creates a virtual building through computer systems, using parametric design methods to produce a realistic structure. This virtual building contains extensive architectural information, including details about building materials, structural elements, as well as the building’s geometric shapes and dimensions.

In addition to geometric data, the virtual model also includes a vast amount of non-geometric information, such as details about walls, doors, and windows. Essentially, BIM technology builds these virtual buildings through specific digitization and informatization processes. Each virtual building contains all the precise, real-world information corresponding to its physical counterpart, much like a mathematical model. By leveraging computer technology to create these models, BIM provides a unified, complete, and consistent building information database for every project.
The construction process of a building project typically involves four main stages: planning, design, construction, and operation. Each stage has distinct tasks and involves a diverse group of participants. These participants can generally be divided into two categories: direct and indirect participants. But how are these roles defined? For example, design firms, construction companies, and supervision units are considered direct participants, as they are primarily responsible for project management. Among them, the owner plays a critical leadership role throughout the project. On the other hand, entities such as government agencies and the general public are classified as indirect participants. The involvement of numerous stakeholders in a construction project significantly increases the complexity of information management throughout the process.
