ABSTRACT
This paper introduces a novel decision-making approach for interventions on existing concrete bridges, demonstrated through a case study of a bridge in the metropolitan region of Amsterdam. By redefining system boundaries, incorporating environmental impacts from traffic disruptions caused by structural and non-structural intervention activities, and by quantifying societal impacts in terms of additional costs for the users, this approach promotes a sustainability-centered decision-making for the early stages of determining measures for existing assets. The proposed methodology ensures that decisions regarding replacement, renovation, and/or traffic restrictions are not only technically sound but also aligned with broader sustainability goals, resulting in more balanced and transparent outcomes. The outcomes of the study underscore the importance of accounting for network-wide impacts and societal costs in advancing the sustainability of interventions on existing concrete bridges.
