BIM has rapidly gained popularity and attention in our country, attracting many newcomers who are still unclear about what it truly is. Although we have covered this topic before, today, with a focus on helping beginners, we will explain what BIM is in a clear and concise way.
Numerous institutions and experts have defined BIM. The Facilities Information Council of the International Organization for Standardization describes Building Information Modeling (BIM) as a computable representation of the physical and functional characteristics of facilities, along with related project lifecycle information, all based on open industry standards. This supports better decision-making and maximizes project value.
The National Institute of Building Sciences in the United States defines BIM as “a digital description of the physical and functional characteristics of a facility.” This represents a complete transformation of traditional concepts, providing a reliable basis for information sharing throughout the facility’s lifecycle. The American Institute of Architects views BIM as a model-based technology linked to project information databases. Similarly, Ghang Lee describes BIM as the process of collecting and managing relevant information throughout a building’s lifecycle.
In summary, BIM has two fundamental characteristics: it is an information technology applied throughout the entire lifecycle of a project, and it emphasizes information sharing. Essentially, BIM acts as a comprehensive network centered around information technology. Vertically, it covers the entire process—from design and construction to use and demolition. Horizontally, it involves various stakeholders such as owners, designers, contractors, supervisors, cost consultants, and suppliers of materials and equipment. Through this network, these parties can access accurate, timely, and convenient information at every stage of construction, enabling informed decision-making.
The effectiveness of BIM depends on the type of information it provides. This information has several key traits. First, it is numerical and component-based. Unlike traditional designs where elements like walls, doors, and windows are mere lines without physical meaning to computers, BIM treats them as components with physical attributes and technical specifications, allowing for analysis and validation. Second, this data is managed by the Building Information Model itself. Traditional design drawings resemble a poorly organized warehouse where finding specific items is difficult. BIM, however, functions as a smart management system, enabling users to quickly obtain the information they need. Finally, BIM presents information in a user-friendly way. Traditional design data is two-dimensional, requiring professional knowledge and spatial imagination to interpret. BIM uses three-dimensional visualization to show the building’s final appearance to owners and stakeholders, significantly reducing the technical barriers for decision-makers. In essence, BIM represents a new, integrated, and parametric design approach.
BIM employs the most advanced modeling techniques available today, integrating numerous industry-specific tools to express building information in great detail. As a new frontier in building informatization, BIM has evolved from theoretical concepts to practical applications, bringing both challenges and opportunities to the construction industry—from design and construction to management and operation. Designers can optimize and compare solutions more effectively using BIM models, while contractors gain access to more reliable technical details. Project managers can combine BIM with 4D simulation technology to enhance construction project management efficiency. After construction, mature BIM models also assist facility managers in maintenance and major repairs.
