From the following two sources, we gain a comprehensive understanding of the core capabilities of Building Information Modeling (BIM):

First Document: In June 2012, Mr. Deke Smith, Chairman of the BuildingSMART Alliance in the United States, summarized the 10 core principles of BIM technology. He presented these principles while introducing the development of BIM technology in the U.S. to the research group on “Development Strategies for BIM Technology in Survey, Design, and Construction” under the Ministry of Housing and Urban-Rural Development. The principles are as follows:
- Coordination
- Lifecycle perspective
- Reference model construction
- Detailed data, including
- Input data at once
- Data maintenance
- Information assurance and metadata
- Data contract
- External access under protected conditions
- International standards

Second Document: The National BIM Standards in the United States categorize BIM capabilities into 11 areas related to BIM maturity models:
- Data-rich category
- Lifecycle
- Change management
- Role or profession
- Business process
- Timely response
- Submission method
- Graphic information
- Space capability
- Information precision
- Interoperability / IFC support
Drawing from these two sources and considering the current status of BIM implementation in China’s engineering construction industry, we summarize the core capabilities of BIM technology into three main aspects:
1. Information Sharing Capability: This is the heart of BIM, encompassing information content, format, exchange, integration, and storage.
2. Collaborative Work Ability: This refers to the application processes, methods, and management capabilities of BIM. It involves process optimization and decision-making assistance that set it apart from traditional approaches.
3. Professional Task Capability: This defines BIM’s goal and professional proficiency, including adherence to professional standards, efficiency, effectiveness, and cost control in completing specialized tasks.
Addressing these three core competencies is essential for successfully implementing BIM technology and enhancing work efficiency and quality across the construction industry.
