Very interesting paper showing results of semi-structured survey about BIM in AEC. I enjoyed the feedback presented from groups and I think most of the comments critically the pros and cons about the BIM implementation. The paper will generate an interesting debate in ACSAAD conference.
One important remark, the content of the paper doe not match the title. I was expecting to read more about how your survey found answers to critical issues such as: how BIM provides evaluation of the building to comply with Part ‘L’ regulations? Have you explored SBEM developed by BRE that is currently being used by architectural firms in UK?

General comments:
- I think the author is confusing BIM that stands for Building Information Modeling with Building Integrated Modeling. The known term of BIM is Building Information Modeling.
- Section 1, paragraph 1: replace ‘… mediums…’ with the plural ‘media’..!!
- Section 1, paragraph 1: wasn’t the term BIM coined by Graphisoft ArchiCAD!! Please check or provide a useful reference to that. Let’s not confuse readers!!
- If possible include Figure two within the body of the paper after mentioning it in the text.
