The value of BIM technology is often either overly glorified or underestimated. From a practical standpoint, its true benefits can be summarized as follows:
1. BIM-Based Engineering Design
First, starting with the pre-prepared data from various professional CAD systems, a complete 3D design is created. Then, the logical relationships between different disciplines, trades, and processes are derived from the 3D model. Finally, through a BIM integrated design platform, collaborative design and management across multiple disciplines are enabled. When one discipline changes parameters due to technical requirements, related disciplines are automatically updated, achieving intelligent, visual design and minimizing redundant work.
2. BIM-Based Construction and Management
The initial step involves implementing Integrated Project Delivery (IPD) based on the comprehensive BIM model. Experienced engineers simulate critical processes such as design and construction while collecting data from all parties. These 3D BIM models are used in a visual environment to enhance understanding.
Next, 4D construction management leverages visualization, integration, and dynamic management by linking 3D models with real-time construction site information. This creates an integrated data structure that enables on-site progress visualization, dynamic simulation, and effective management.
Finally, from a collaboration standpoint, the BIM platform facilitates file sharing, data exchange, information dissemination, and teamwork among all stakeholders, simplifying workflows across various roles.
3. BIM-Based Building Operation and Maintenance
This phase integrates GIS technology with BIM, allowing effective management and control of mechanical, electrical, and other functional building systems.
BIM also provides a foundation for energy consumption analysis and energy-saving strategies during operation and maintenance.
Additionally, by analyzing disaster impacts along with business-related data on injuries and material quality, BIM helps predict and assess the duration and extent of environmental damages, enabling better emergency response and recovery planning.
