The "National Roadshow," which has been held at various venues across Japan, will be transformed into an "online format."

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. Please join us as we take the first step towards confirmation applications utilizing BIM and as a platform for organizing information right after the system starts.
