BIM according to Carea


Do not confuse BIM with digital mock-up

BIM was born out of the desire of the building industry and software publishers to exploit the 3D and attribute possibilities of the computer tool in application to the needs of the construction sector.

It is difficult to find a universal definition of BIM (Building Information Modeling). BIM is first and foremost a working method applied to the elaboration of 3D parametric digital models that contain informed and structured data.

The objective of BIM work is to optimise the sharing of information throughout the life of a building or infrastructure, from its design to its deconstruction.


The digital mock-up is a tool for digitally representing the physical and functional characteristics of a building or infrastructure.

In the course of a collaborative project, the actors work to individually evolve their respective models which, once combined, make up the digital model of the project.

BIM levels and levels of detail

The BIM levels are used to classify the level of use by a building stakeholder.
It is generally accepted that :

  • in 2D, level 0,
  • in simple 3D, level 1A,
  • in 3D + attributes, level 1B,
  • in collaborative 3D, level 2.

The LoD (Level of Details) is used to classify the quality of representation of a 3D digital object.
In the study phase, the LOD varies according to the attribute and geometric details:

  • LoD 100: simplified representation of an object (operational phase: sketch),
  • LoD 200: improved representation of an object (operational phase),
  • LoD 300: final representation of an object + technical attributes (operating phase).

Our approach to meeting your challenges

Digital innovation, driven by BIM, now makes it possible to anticipate the constraints on the ground right from the design stage of a project. It is clear that your needs differ between the sketch and the production of the tender documents. As a supplier, CAREA makes it a point of honour to support the building designers at each phase of the project. In this sense, we have initiated a process of opening up to BIM in order to sequence our database in accordance with the currently recognised BIM classifications.

This is now available above.
