Itacus was co -hosting and visibly present at the stimulating IABR - 2016 - Urban Underground Day in Rotterdam, on June 23, 2016. The inspiring and thought provoking event was held in former factory spaces in the old port of Rotterdam. In a packed and innovative theater space, Yvette Koerber held a talk on Innovative Urban Logistics, while Han Admiraalstimulated the debate about connecting to the next generation with our Young Professionals from London and Paris on the stage: Petr Salak, Nicolas ZIV, Loretta van der Tan and Anita Wu. The talks were held in relation to the day's theme of " The Next Economy", how it will affect our urban and spatial development, our infrastructure requirements, and the role of urban underground space in this context. The day was attended by 130 participants from the architectural, engineering, sustainablity, energy and design domains and hosted by Rotterdam's resilience program's office. http://isocarp.org/events/underground-day/
