There is a lot of debate over the acronym of BIM. I like the ‘brief primer’ from EcoDomus:
BIM is an acronym for a few things:
1) Building Information Modeling (virtual design process),
2) Building Information Model (a set of files and/or databases that includes 3D geometry and corresponding data), and
3) Building Information Management (lifecycle use of building data).
Their product focus is on the #3 version: Facilities Management, and they propose data integration and management across several well known controls systems. Check ’em out.
