The construction mediators (médiateurs de chantier) contribute to the flow of information between Luxembourg City's residents and its municipal administrations, they gather suggestions, convey complaints to the respective work site supervisors, and inform the general public about the progress of the work sites, as well as any changes resulting therefrom, in particular as concerns traffic and public transportation. The deployment of construction mediators for the urban environment also reflects the City's desire to provide transparent information about its construction projects and promote dialogue with citizens.
