Kimon Onuma presented at TEDx Americas Finest City about how technologies like fire, stone carving, and paper have historically helped communicate ideas and advance civilization. He discussed how social media and building information modeling (BIM) now enable new forms of data-driven collaboration online. Through case studies of BIMStorm projects, Onuma showed how making asset data openly accessible in real-time across agencies and on mobile devices can improve consensus decision making for facilities management and campus planning.
