I'm very intrigued by your investigation (LOG). The IFC was and is an imported topic since approx the last decade.
The abstract is too long (it’s a copy from the first abstract submission only).
The description of the current situation and the motivation are well written and clear – these reflect the current "every day" situation. In the following paragraphs, the author describes two case studies. In the conclusion the author wrote "... the LOG of BIM primarily depends upon the specific needs of each project." That is not really a new stated view. 
I miss in this context more clear solutions, statements, requirements etc., e.g. a general description of such a framework, criteria’s and effects on the BIM - the integration of communications aspects in process modeling.
