This dissertation asks "what are the challenges for citizen engagement introduced by increasing smart urban infrastructure in public space and how can those challenges be mitigated?" It theorizes that the infrastructure that makes cities operational dictates the lives and experiences of the practitioners of public space. It builds from a four-year observational and qualitative research study on a singular infrastructure, engaging multiple stakeholders in public space. At the center of its unique research design is the MX3D bridge, the world's first 3D printed stainless steel bridge, installed in Amsterdam. Its goal is to use research through design and empirical philosophy work with the 3D printed smart bridge in Amsterdam to bridge the gaps between humans and their infrastructure, specifically "smart" infrastructure in the built environment.Using observational and qualitative methods, the dissertation bridges theory with empirical study, centering how smart infrastructure affects people's lives and the political consequences of an uninformed public. We depend on infrastructure to navigate daily life, whether it be streetlights, electrical grids, or footbridges. When these systems work, we overlook their significance, and they disappear into the background. However, smart infrastructure is multi-functional in ways often invisible to the public. Although it might be undesirable to continuously acknowledge the infrastructures that make modern life possible, negative consequences may result if the public fails to understand and civically engage with smart infrastructure when the functionality, purpose, and even ownership of the built environment may shift due to smart city advancements.
The Smart CityCities are important. As of 2022, 56% of the world lives in cities and 68% is predicted to live in cities by 2050 ("World Cities Report 2022" 2022). Cities have long pushed technological advancement and been strategically designed based on the values of those with the power to mold public space. The streets, sewers, buildings, and framework of Paris were famously redesigned by Georges-Eugène Haussmann and then finished by the Third Republic from the
