This collection of abstracts serves as a gateway to the presentations given at the CTBUH 2018 Conference, which took place across Dubai and Abu Dhabi, United Arab Emirates, from 20 to 25 October, 2018. The presentations upon which these abstracts are based continue the discussion begun at the 2017 Australia Conference “Connecting the City,” debating the merits and challenges of the polycentric approach to urbanism, and dedicated to understanding and envisioning how tall buildings, density, infrastructure and people fit into this vital mix. This is reinforced by the on-site visits and detailed design presentations of projects embraced in the conference program.
