Bim modelling

BIM (Building Information Modelling) is an intelligent 3D model-based process that gives architectural, building and engineering professionals the tools to plan, design, construct and manage projects. It requires “an information exchange process which is specific to that project and coordinated between various systems and project participants.”

We use BIM Levels 1 & 2 to:

1.  Agree roles and responsibilities.
2. Agree naming conventions.
3. Create and maintain the project specific codes and project spatial co-ordination.
4. Create a common data environment to allow information to be shared between all members of the project team.
5. Agree a suitable information hierarchy which supports the concepts of the CDE and the document repository.
6. Agree to use CAD software that is capable of being exported to one of the common file formats such as IFC or COBie.
