In this online seminar, we will organize and clearly explain the overview of the BIM drawing review system, the concepts behind the review, and the key points that should be understood in practice, providing the foundational knowledge necessary for confirmation application work. We will also address questions such as "What should I prepare first?" and "To what level should I respond with BIM?" from a practical perspective.
