The removal of the ‘beta’ logo doesn't mean that the toolkit journey is at an end - but it is a sign that all of the functionality is working correctly and that it is ‘release quality’.
At the BSI BIM conference I presented three of the main concepts behind the BIM Toolkit: Classification; Levels of Definition and Digital Plans of Work. I have written three short blog posts to go through these slides as an introduction to these. This second blog post is on levels of definition.
At the conference, I attempted to work through an analogy reflecting on how content for an event was developed. Three months before the conference the speakers would provide a description of their presentations. Two months before the conference they’d provide an outline of the proposed slide sequences. Nearing the conference date a final draft would be provided and then the actual presentation would be published as a record.

These principles apply also to the construction industry. These levels of definition can be split into ‘level of detail’ which relates to the geometric detail and ‘level of information’ which defines the information related to the model. The slides below illustrate this:
