Definition of BIM

BIM (acronym for Building Information Modeling) corresponds to a working and project management method based on the digital model of a building and the information it contains.

As the building sector is undergoing its digital revolution, BIM is integrated into the very core of this transition.

Why is BIM a revolution?

This way of working around the digital model of the building, a true spatial and informative reference system for buildings, has a very high potential throughout the life cycle of the building.

Thanks to the BIM processes, building information is correctly made available to the stakeholders of a project, in a precise spatial frame of reference. The use of the digital model will make decision-making more reliable in the overall management of buildings, but also during more specific study projects and project designs.

Ultimately, collaborating around a digital model on a specific project or over the entire life cycle of the building will improve decision-making, save time and save money.

This is why architecture firms, engineering firms, construction companies or operators initiate their project in BIM.

How to initiate a BIM project?

To initiate a BIM project, it will first be necessary to conduct an internal audit of the expectations and needs of building actors. Concrete use cases will be identified, which will make it possible to define the types of information and the level of geometric detail (LOD) required in the model.

This audit will make it possible to make the BIM functional specification document for a specific project or for a more global BIM strategy. It will then be a question of producing the digital model (s) of the project. This phase of BIM modeling relies on an assessment of the existing conditions, either through the scan-to-BIM method or using building plans
