In the construction and architecture industry, CAD and BIM technologies and methodologies are widely used in the development of complex infrastructure. In this article, we will clarify some doubts regarding the parallels and differences between these technologies.
Bear in mind that while both have similarities, they present significant differences in terms of the philosophy and way of working they entail.
Parallels between CAD and BIM
The first thing to highlight is that both technologies aim to create models that represent the project in advance, allowing for a preview so that stakeholders and construction professionals have adequate graphical information to understand and build the plans.
Among the similarities between CAD and BIM, we have:
- Graphical Representation: Both methods allow for the creation of 2D and 3D drawings and models, enabling adequate previewing.
- Design Presentation: Ideas are difficult to convey without a graphical interface, which is what both technologies provide.
- Aid and Guide in Construction: Both the CAD-generated model and the BIM model help in the precise construction of a project.
Divergences between CAD and BIM Technologies
Despite these similarities, there are fundamental differences that distinguish CAD from BIM, especially in terms of information management.
CAD (Computer-Aided Design)
- Geometric Focus: CAD design primarily focuses on creating geometric drawings that provide a detailed visual representation but lack additional information about the construction elements.
- Limited Data: CAD models, though precise in terms of geometry, do not contain data on the relationships between elements or their behavior. This means additional details, such as material specifications or physical properties, must be managed separately.
- Collaborative Aspect: CAD mainly relies on file exchanges where all development versions must be updated, which is prone to errors and conflicts.
BIM (Building Information Modeling)
- Beyond Geometry: BIM not only provides geometric representations of the building but also captures metadata, the behavior of construction elements, and information such as materials, duration, costs, etc.
- Centralized Database: BIM has a centralized database containing all project information, allowing for efficient and precise management, reducing the likelihood of errors.
- Effective Collaboration: The centralized database also facilitates effective collaboration among all project participants. By working with a centralized model, all changes and updates are reflected in real time, ensuring that everyone works with the most recent and accurate information.
- Improved Efficiency: Thanks to the integration of measurement data, materials, and resistances, among others, the BIM methodology allows for the simulation of the building’s behavior, improving work efficiency and significantly reducing project errors and risks.
