Speakers and leaders gathered for a photo following the forum presentations.
Additionally, CTBUH members were treated to an exclusive technical tour of the 123-story Lotte World Tower, which is under construction in Seoul. Attendees first received a presentation on the history and development of the supertall building before a guided tour took them up to the 114th floor. There they were able to view the current state of construction and take a closer look at the diagrid structure which is the main structural support for the top 16 floors.

The event was a great success, and plans are already being laid for next year’s forum, which will be hosted on July 7, 2016 at the Tokyo Institute of Technology.
