The foundation of BIM is not 3D. It's information. Discover how data modeling changes the way we design, build, and maintain structures.
When we talk about BIM, Many people still only think about "3D models." But what truly transforms the way we design and build is... Building Information Modeling or, in English, Building Information Modeling.
This modeling is what makes BIM much more than just a pretty visual: it organizes all the technical data of the project, connects disciplines, generates predictability, and reduces errors.
In this article, you will understand what "building information modeling" really means, and why it's so important. in addition to technical drawing and how to apply it in practice within the reality of construction companies, designers and managers.
What is building information modeling?
Simply put, it's the process of creating a digital model that represents not only the geometry, but all the technical information associated with each element of the work.
Each wall, beam, light fixture, or duct contains data that may include:
- Dimensions, volume and area;
- Type of material;
- Supplier and unit cost;
- Relationship with systems (electrical, structural, hydraulic);
- Execution schedule (BIM 4D);
- Cost data (BIM 5D);
- Operation/maintenance manual (BIM 6D);
- Warranty, lifespan, maintenance history.
In other words, it's as if the model were a living work of art, with everything documented in one place.
Difference between geometric modeling and information modeling.
| Geometric modeling | Information modeling |
| Visual only | Visual + technical |
| Focus on 3D | Focus on the data |
| Good for presentation. | Essential for execution |
| Limited applicability on the construction site. | Basis for extracting quantities, schedule and budget. |
While geometric modeling generates the "design," information modeling generates the "content" that makes that design work in the real world.
How BIM organizes everything based on modeling.
Based on information modeling, BIM allows projects to be structured with:
Data centralization
Instead of spreadsheets, emails, and loose files, everything is in the model: materials, systems, costs, construction steps, and more.
Multidisciplinary coordination
Models from various disciplines are federated (coordinated) in a single environment, where they can be precisely matched.
Automatic information extraction
Bills of materials, quantities, area maps, cost spreadsheets, schedules. Everything can be generated directly from the template, without manual rework.
Decision tracking
Every decision made in the project (such as layout changes, supplier changes, or cost adjustments) is documented in the model.
Real-world applications of information modeling.
BIM information modeling is used in several stages:
Projects and compatibility
Avoid discrepancies between architecture, structure, and installations before execution.
Budget (BIM 5D)
It allows you to generate accurate budgets based on the modeled elements, not on generic estimates.
Planning (BIM 4D)
Each element of the model can be linked to a task in the schedule, making it easier to track the progress of the work.
Operation and maintenance (BIM 6D)
After the project is completed, the model remains useful, functioning as a digital construction manual with data for maintenance and asset management.
Advantages of Building Information Modeling
- Full integration between design, budget and construction;
- Reducing errors caused by misinformation or rework;
- Faster and more informed decision-making;
- More efficient construction monitoring;
- Greater clarity for those who design, build, and manage.
How to begin?
Applying Building Information Modeling requires:
- Define standards and flows (BEP);
- Standardize families and objects with parameterized data;
- To train technical teams;
- Use data visualization, matching, and extraction tools;
- Having support from specialized consultants (like Cadbim).
Building information modeling is the heart of BIM.
In addition to being the safest way to organize, forecast, and deliver more efficiently.
And Cadbim helps companies apply this methodology with structure, clarity, and practical results, always working together.
