BIM technology features three key characteristics: visualization, digitization, and information sharing. These features address the traditional challenges of hidden, incomplete, and unstable engineering data. As a new way of thinking and working, BIM transforms the conventional approach to information management, which primarily relied on 2D drawings as the main information carrier. For this reason, BIM is often regarded as the second revolution in the construction industry, following CAD.
Drawing from existing theories and research, BIM can be defined as a digital technology that uses parametric models to share and transmit diverse engineering information on a stable, collaborative platform. The ultimate goal is to enhance management decision accuracy and advance information technology within the construction sector. In essence, BIM software serves as the tool for implementing BIM technology, with engineering information as its core, building information modeling as its output, and the sharing and conversion of building data as its foundation.
The latest advancement, BIM 5D technology, effectively integrates 3D building models with digital data on cost and time, enabling the creation of efficient and scientific project management models.
BIM technology offers the following features:
1. Physical Operation Method: BIM software allows users to work with three-dimensional representations of architectural forms, replacing traditional geometric elements like points, lines, and rectangular prisms.
2. Parametric Expression: Every building object in a BIM model is a digital representation that encompasses both physical and functional characteristics, providing essential data for ongoing information management.
3. Highly Integrated Information: BIM’s database technology stores all engineering information throughout a building’s entire lifecycle, making it easily accessible to all project stakeholders.
4. Optimization Capability: Given the growing complexity of modern construction projects, BIM technology and related software tools enable effective project optimization beyond the capabilities of individual participants.
5. Support for Open Standards: By supporting the exchange of building information through open standards, BIM facilitates data sharing at every stage of construction while reducing redundant data entry.
