Annemarij Kooistra

Director of City Deal Future-Proof Canals
Amsterdam, Netherlands
READ MORE
Annemarij Kooistra is currently the director of a City Deal Network “Future Proof Inner City Canals”, where she plays a key role in building alliances of municipalities facing large renovation challenges of the historic canal walls, bridges and sluices in the city centers. A challenge of preservation of cultural heritage combined with necessary climate adaptation, modal shift in mobility and energy transition in the public space of the canal systems. Together with industry and research institutions best practices are shared and new standards developed.

In the city of Amsterdam she was as a program director responsible for the assessment of the civil structures, and the research program to develop futureproof solutions for Amsterdam bridges and canal walls. Innovations on monitoring and sensoring, assessment strategies, value based decision making and synergy between renovation and future proof public space were tested and implemented. And within the city deal network now shared and further developed.   

Scaling innovations and implementation of newly developed standards do not only ask for technical solutions. Real transition towards a net zero future ask for social innovations and new ecosystems. Leaving old ways that served us well in past decades is hard and should not be underestimated. Embracing the new can make us feel insecure. Creating a safe environment for leaving the old and facing the insecure and unknown future is part of building the alliances within the city deal.

David is also founder of TimberFever® a design-build competition run by his company for engineering and architecture students across Canada and the United States.

Michael Haist

CEO of DAfStb (German Committee for Reinforced Concrete)
Stuttgart, Germany
READ MORE
Michael Haist is Professor and Director of the Institute of Construction Materials (IWB) at the University of Stuttgart, where he leads research and teaching in the field of construction materials and concrete technology. He also serves as Chairman of the Deutscher Ausschuss für Stahlbeton (DAfStb), one of Germany’s leading organizations for the development and standardization of concrete construction.

His research focuses on sustainable and resource-efficient concrete construction, low-carbon cementitious materials, durability and performance of concrete structures, as well as the digitalisation and automation of concrete production and quality control. In recent years, he has been particularly involved in advancing concepts such as “Concrete 4.0”, combining artificial intelligence, computer vision, and data-driven approaches with concrete technology.

Prof. Haist has coordinated and contributed to numerous national and international research projects and has published extensively on topics including climate-friendly concrete, fresh concrete rheology, durability, digital quality assurance, and circular construction materials, thereby contributing significantly to the transformation towards more sustainable concrete construction.
