The BIM collaborative management platform is built upon the project’s BIM building model, connecting all stakeholders through a unified platform. This integration enables seamless interaction and transmission of all project data, information, and models, facilitating the comprehensive sharing and integration of engineering project information. Consequently, the development of a BIM-based collaborative management platform focuses primarily on the following key aspects:
1. BIM Basic Model
The BIM basic model serves as the foundation for integrated lifecycle management of construction projects. Different stakeholders require access to various data at distinct project stages. As the project advances, data volume grows exponentially. To manage this efficiently, BIM models with varying levels of design detail are created at different phases, with the project divided into stages based on key milestones. This approach allows for systematic identification, classification, and storage of engineering information across disciplines at each stage.
The information model can be expanded and updated by extracting data from previous stages. Additionally, the established BIM model can reflect the latest project progress and details at corresponding time points, enabling management personnel to update data on the platform for future reference and use.
2. BIM Information Data
In China’s construction industry, enterprises often operate within relatively independent environments, making it difficult to share the vast and complex construction information generated by different parties. This results in low levels of integration and information sharing in project management. To address this, a unified information exchange format such as IFC (Industry Foundation Classes) is essential to prevent data misinterpretation.
Furthermore, when exchanging engineering data based on BIM technology, a dedicated project database should be established to allow participants timely access to project information. This database supports extraction, editing, and storage of engineering information at each project node (IDM). Prior to modeling, it is crucial to classify Building Component Information (IFD) to avoid cross-modeling of building components across disciplines.
3. BIM Information Security
Traditionally, engineering information is stored separately by discipline, either in paper or electronic formats, often scattered across various archives. This fragmentation makes locating and utilizing specific drawings time-consuming and complex. BIM technology offers a more secure and reliable method for storing project information.
According to the editor at Leg Leg Teaching Network, BIM databases consolidate project information from different stages and disciplines into a single model. Completed work information from each project phase should be organized and stored within the BIM project database. Users can then easily search for required data based on project nodes or subprojects.
Moreover, platform administrators can control user access by setting read permissions within the collaborative management platform and its database, thereby ensuring the security of sensitive project information.
