Abstract:The increasing attention for the circular economy in the construction industry can be explained by the industry’s substantial amounts of raw material usage, waste production and contribution to global greenhouse gases. Part of public clients task is the renovation and replacement of bridges that (nearly) reached their end-of-life. The need to incorporate circularity in these projects is well-recognised by public clients. However, current project management and processes do not consider circularity explicitly, which may impede adoption of circularity in bridge projects. Therefore, this study aims to formulate recommendations towards the Province of Overijssel on the organisation of the initiation phase of circular bridge (re)construction by analysing the current process in practice and comparing that with state-of-the-art insights on circular development. Doing so, the initiation phase of a real-world project was studied, which covers two bridges that are representative for other bridges. A pattern matching strategy was selected to explain differences and similarities between theory and practice in the qualitative analysis of the data collected by observations, interviews, document analysis, and a panel discussion. This study shows that four processes are particularly important for circular bridge development from a client’s perspective, which are 1) formulating the project ambition, 2) composing the project team, 3) deciding to refuse, renovate or replace, and 4) consulting the market. Theory and practice of these processes match to certain extent. Based on the insights, it can be concluded that there are certain points desired for the initiation phase, these are mainly 1) circular ambitions on asset management level, 2) procurement- and circularity advisors in a project team with circular commitment, 3) circular indicators in performance-cost-risk assessment, and 4) early involvement of market parties. These insights provide further clarification for science on processes in the initiation phase of circular bridge (re)construction, and allow practitioners to use the insights and reshape their initiation phase for future bridge renovation and replacement projects.
