Building Information Modeling (BIM) refers to computer-aided design using 3D object-oriented technology. It involves managing the acquisition of relevant information precisely when and where it is needed. BIM creates models based on building data, simulating real buildings through digital information. Because of this, BIM offers features such as visualization, coordination, simulation, and optimization.
As an innovative approach throughout the building lifecycle, BIM not only meets the information needs of facility management operations but also reduces operational costs. It enhances the retention of equipment completion data and maintenance records, making it a key trend in the future development and application of building management.
BIM enables the creation of a 3D virtual model of a building, showcasing both its exterior and interior, along with the configuration of ancillary facilities. It stores essential operation and maintenance information within various building components, allowing management personnel to quickly locate equipment. The primary strength of BIM during the planning and design phase is model visualization. During construction, it focuses on progress tracking and cost control. In the operation and maintenance phase, BIM excels in facility management and upkeep.
Overall, BIM integrates applications across all stages of the building lifecycle, delivering comprehensive benefits. It assists in managing building spaces, visually simulates interiors and exteriors, and clearly displays the distribution of different areas within the building. Currently, BIM’s main applications are concentrated in the design and construction phases, making it crucial to import data from these stages for backend operation and maintenance.
Traditional material management often relies on paper-based records to track construction equipment data. However, this method is cumbersome to manage and store, and prone to redundant work when updating maintenance records. Previously, owners and managers maintained data in various formats, which were not easily interchangeable.
Lewis & Whittaker highlighted three major issues caused by paper-based record-keeping:
1. Facility and equipment management data is frequently duplicated.
2. Data cannot be shared or utilized effectively by facility management systems.
3. Incomplete management data often impairs decision-making.
The BIM concept of building lifecycle facilitates communication among professionals at all stages, integrates and consolidates information, overcomes data retrieval challenges, and supports completion and acceptance processes.
In conclusion, today’s discussion covered the development of BIM-based operation management. Currently, China is focusing on integrating basic information with BIM applications for future property management. Contracts stipulate the Level of Development (LOD) for BIM models during construction, requiring contractors to establish different LODs for structures, doors and windows, exterior walls, decoration, machinery, plumbing, electrical, air conditioning, and other systems. BIM completion models are integrated to assist owners in building accurate models, ensuring they pass inspection and acceptance before handover.
