What is bim modeling

For many years, the question of how to manage buildings in accordance with the principles of efficiency and effectiveness has been a major challenge for the building world. This debate has received renewed attention since the advent of Building Information Modeling (BIM ) . A BIM model contains information about a building or its parts, such as geographic location, geometry, properties of materials and technical elements, construction stages, maintenance operations. This allows useful information to be integrated into the model at every stage of planning, from architectural to executive. , (structures, systems, safety, maintenance, energy efficiency, etc.) and management (calculation of indicators, supplier lists, etc.). BIM is a collaborative design method based on integration. It can be used by installers and civil engineers, architects and accountants, builders, installers, auditors, testers.

Adopting this design system also allows for improved teamwork , whereby designers, civil engineers, installers, and construction companies can collaborate on a centralized project, each with their own discipline.

There are many benefits to using a BIM design system: it is richer, more complete, and more accurate than the equivalent created with traditional 2D CAD systems. Active participation, access to constantly updated information and coordination due to the joint use of a single model dramatically reduces the rate of errors and inconsistencies , therefore, reduces the number of changes and, ultimately, design costs, making everything more economically sustainable.

Why use BIM?

Building Information Modeling (BIM) design makes planning, design and management of buildings more efficient. By creating a BIM model, architects and civil engineers can quickly consider a range of potential projects. This allows them to look for the best solution based on many factors: material cost, usability, energy efficiency, etc.

Traditionally, architectural design has been based on 2D technical drawings. This has often led to misinterpretations and inconsistencies. On the other hand, bim modelling offering an extra dimension to help all those involved in the project, a better understanding of space and the relationship between the different elements of the building.

BIM offers an additional layer of data to the 3D model . BIM allows each professional to add their data to the model. By incorporating all levels of development (LOD = levels of development) into the same model (eg architectural, structural, and MEP), it is easier to plan and coordinate a project, highlighting any conflicts and inconsistencies.

Another benefit is the ease with which you can quickly add annotations to BIM drawings, since the required data is already contained in the geometry.
