30 Most Common BIM Terms

Since 2023, in Vietnam, the application of BIM has officially become a mandatory requirement for Grade I and special-grade construction projects funded by public investment.

A deep understanding of BIM-related terminology is key to using BIM effectively in construction.

BIMCAD Vietnam has compiled a list of 30 of the most common BIM terms, inviting readers to explore and learn more in the content below.

Common BIM Terms Today

1. BIM 3D: This refers to the three-dimensional spatial modeling of buildings, integrating information from design, structural components, electrical systems, plumbing systems, and more. It enables stakeholders to easily visualize the structure of a project before construction begins.
2. BIM 4D: This combines the 3D model with the time dimension to help manage the construction schedule. Through this integration, managers can track construction progress using visual simulations and real-world imagery or videos.
3. BIM 5D: An extension of BIM 4D, this model integrates cost information into the construction process, helping manage finances, estimate project costs, and optimize construction workflows.
4. BIM 6D: As the next step after 5D BIM, BIM 6D adds operational management and energy performance analysis. It supports lifecycle management, asset optimization, and improved operational efficiency.
5. AIM (Asset Information Model): AIM is a model that collects the necessary data for asset management, including operational information, maintenance records, user manuals, and other related documentation.
6. IFC (Industry Foundation Classes): This is a standard file format in BIM that enables easy and accurate information exchange between different BIM software platforms and tools.
7. BCF (BIM Collaboration Format): BCF, based on XML, allows comments and issue tracking to be attached to IFC-based BIM models, facilitating communication and problem tracking during design, construction, and project management.
8. BIM Execution Plan (BEP): BEP is a BIM project development plan prepared by the client or contractor, providing a foundation for BIM implementation before and after the project contract is signed.
9. BIM Maturity Levels: This concept measures the level of BIM development and adoption within a project, ranging from basic awareness to full integration and optimization.
10. BIM Protocol: This protocol defines the rules, standards, and specific procedures for using BIM, ensuring that all stakeholders follow agreed-upon principles.
11. CAD (Computer-Aided Design): Software and technology used to create and modify technical drawings and 2D/3D models, improving design accuracy and productivity.
12. CDE (Common Data Environment): A platform or system used to exchange, store, and manage shared project information, including BIM files, drawings, models, and related documents in a cloud environment.
13. COBie (Construction Operations Building Information Exchange): A spreadsheet-based data format used in BIM models, focusing on delivering asset data rather than geometric information.
14. EIR (Employer’s Information Requirements): This describes the specific BIM data and information requirements expected by the client, including file formats, data standards, and information presentation.
15. iBIM: Integrated Building Information Modeling, also referred to as a BIM maturity level.
16. IMP (Information Management Process): A set of processes and standards for managing information in construction and project management, playing an important role in BIM implementation.
17. BIM Level 0: At this level, CAD is used to support design by producing 2D drawings, with information exchanged via paper or electronic files without standardized processes or integrated data as in BIM.
18. BIM Level 1: At this stage, design is supported by CAD through 2D or 3D drawings with some attached information. Although certain standards for sharing and management may exist, the full benefits of integrated information management through BIM are not yet realized.
19. BIM Level 2: This level improves accuracy and efficiency in project and construction management by using BIM 3D, 4D, and 5D models along with project management software and information management systems.
20. BIM Level 3: This collaborative working model includes a 3D project model integrated with schedule information (4D), cost information (5D), and lifecycle management (6D), including maintenance and replacement processes.
21. Level of Definition: A general BIM term describing the level of detail and information contained within a model.
22. Level of Model Detail (LOD): This term describes the level of graphical detail of elements in a BIM model, helping users understand the model’s completeness and accuracy.
23. Level of Model Information (LOI): Similar to LOD, LOI refers to the level of detail and accuracy of the information contained within the 3D model.
24. PAS 1192-2: A specification for information management during the capital delivery phase of construction projects using BIM.
25. PAS 1192-3: This specification manages information during the operational phase of construction projects using BIM.
26. PAS 1192-5: A technical specification for secure BIM implementation in digital environments and smart asset management.
27. Project Execution Plan (PEP): Defines the overall strategy for managing a project, including policies, procedures, and priorities to be applied.
28. Project Implementation Plan (PIP): A document presenting a supplier’s IT capability and human resources to meet EIR requirements. It is usually part of the BIM contract before implementation and prepared by each bidding organization.
29. Project Information Model (PIM): Contains information and data related to the construction and operation of a project, including 3D models, building element data, technical documents, schedules, time and cost data, and other project-related information.
30. xBIM (eXtensible Building Information Modelling): An open-source software development toolkit that enables developers to read, create, and view BIM models in the IFC format.

Conclusion

These visualization methods offer many benefits, such as improving design accuracy, reducing costs, enhancing communication among stakeholders, and enabling faster decision-making. BIM will continue to develop as an essential tool in the construction industry, with visualization playing an increasingly important role across all areas of the sector.
