BIM is the process of creating a digital model of a building to facilitate collaboration between all construction stakeholders (from design to maintenance). Degrees of use vary according to the level of collaboration desired by stakeholders: from level 0 (no BIM collaboration) to level 3 (100% BIM collaboration). Here's how it works.
The 4 levels of BIM collaboration
Ranked from 0 to 3, the levels of BIM(Building Information Modeling) collaboration correspond to the maturity of the players involved in each modeling project. The levels also coincide with different degrees of complexity and data integration in the digital model. And different degrees of efficiency!
Level 0: no BIM collaboration
Level 0 corresponds to the lowest level of BIM collaboration. At this stage, 2D drawings are produced using external CAD (computer-aided drafting) software or in paper format. These are then used to design and document the project. Also, all collaboration-related exchanges are carried out by sending electronic or paper documents.
This mode of operation is not conducive to collaboration, for several reasons:
Graphic standards are not uniform - they are left to the discretion of each individual.
Information is neither structured nor centralized.
The majority of projects are not georeferenced, i.e. they are not associated with geographic coordinates and therefore have no spatial location.
