Engineering progress and cost control methods are primarily based on the construction process established during the project planning and design stages. Therefore, it is essential to effectively manage the project by integrating the BIM model with the construction process. Establishing a construction management model that differs from traditional methods and incorporates the characteristics of BIM requires exploration and research. In this article, the author will discuss the key functions of BIM in construction management.
1. Real-time Dynamic Update of Construction Process
As construction advances, the system automatically recalculates and adjusts the schedule based on whether the project is ahead of or behind plan. It continuously updates and executes performance evaluation analyses aligned with the dynamic process. This allows construction managers to engage with ongoing changes, reassign tasks as needed, and utilize progress performance indicators to support informed decision-making.
2. Progress Control Tool
The system offers a flowchart import mechanism combined with progress control analysis methods. It automatically generates performance reports and other key indicators related to project execution. This feedback helps system operators monitor project progress effectively, ensuring timely and smooth completion.
3. Real-time Quantity Calculation Based on BIM
By utilizing the attributes provided by the BIM model, the system aligns material usage and cost calculations with the corresponding construction phases. This real-time data supports efficient material scheduling and cost control throughout the project.
4. Visualized Information Feedback Using 3D Models
The system leverages BIM models to visually represent the current construction status. It simulates the construction process by animating the behind-the-scenes behavior of various BIM components. By comparing actual progress with planned schedules, the system provides alerts and visual feedback, making it easier for users to understand project status intuitively.
5. System Operation Support Functions
Additional features assist with the basic operation of the system, including:
- Importing BIM models
- Grouping BIM components into work projects
- Querying construction information to select model components
- Updating progress and cost data for work projects promptly
- Facilitating model operations
These functions collectively meet the operational needs of the overall system.
In summary, the functions described above demonstrate how BIM-based construction management uses BIM models as a central medium. It integrates information about issues or situations encountered during construction into the model, allowing for analysis, processing, and feedback. This process ultimately supports decision-making among project stakeholders. Therefore, the core of BIM lies in the concept of “I” within BIM—the integration and interaction of information.
