Levels of BIM Maturity Flashcards
What is level 0 BIM?
No collaboration between teams, simple 2D CAD drawings, distribution via paper and/or electronic prints.
What is level 1 BIM?
Mixture of 3D CAD and 2D drafting, data exchange through a common data enviroment, no/partial collaboration between disciplines.
What is level 2 BIM?
All parties combine models into a federated model, design info shared in a common file format (i.e. IFC) using a common data environment.
What is level 3 BIM?
Full collaboration between all disciplines by using a single shared model, all parties can access and modify the same model/
What is a federated model?
A combined/merged model that has been made from several discipline-specific models.
What is a common data environment?
A location where data is shared for a project. You cannot edit other disciplines work, only view in the contextof your model.
What are the advantages of a federated model?
Enhanced clash detection, earlier design development on key decisions, improved estimations.
What is a clash and what issues does clash detection solve?
A 3D spatial conflict and it solves the issue of resolving clashes earlier so they reduce impact and cost to solve.
What is a potential problem with the jump from level 2 to level?
There may be problems with liability and copyright as everyone can edit the model. There is no one person responsible.
What are the 4 types of clashes?
Hard clashes, soft clashes, 4D clashes, acceptable clashes.
What is a hard clash?
When 2 components occupy the same space.
What is a soft clash?
Where an element isn’t given spatial or geometrical tolerances it requires.
What is 4D clash?
Clashes that involve scheduling of equipment, material and general timeline conflits.
What is an acceptable clash?
Geometric clashes that are expected and will not be a problem on site.
How are clashes resolved?
Making rules in the software to ignore clashes or changing the model so they don’t clash anymore.
