Civil engineering structures are regularly confronted with failures that can lead to catastrophic consequences. It is important, after a failure, to be able to identify the origin and the sequence of factors that led to it. This failure analysis by experts, called forensic engineering investigation, generally leads to the drafting of an expert report. These reports do not inform on the processes that guided the experts to a conclusion and the uncertainties involved. This paper aims to propose a new methodological approach to formalize the opinions of experts in forensic engineering.

The research consists in combining abstract argumentation with the theory of imprecise probabilities to take into account epistemic and stochastic uncertainties to support forensic engineering investigation.

A model and a tool to support forensic analysis are presented. An application on the collapse of the Brumadinho dam highlights the interest of the chosen approach.

This work is the first use of the abstract argument framework in civil engineering, and so in forensic engineering. Furthermore, it provides an innovative model based on imprecise probability for AAF.

Links between urban areas and public space have always had a central presence in the field of Urban Sociology. During the last four decades, and in relation with globalization processes, reflection about city places and what constitutes the “public” has increasingly been in line with what has been called an “emplacing heritage process,” which emerged as a controversial point of intervention in urban areas. In this sense, itineraries have been considered of primary importance in urban heritage signification, recognition, and symbolic production. In short, these routes appear as ways in which public space is materially and symbolically occupied, becoming emplacing heritage processes in themselves.

In this chapter, we study two heritage-making processes through neighborhood itineraries, which are carried out in district territory and are located in two peripheral neighborhoods belonging to the City of Madrid (Hortaleza and Carabanchel). Ultimately, the point here is that these routes are not merely a pathway that “goes” along acknowledged heritage places; these itineraries are an emplacement and a signification of patrimony itself. These processes act as markers of iconic places and as remembrance performances of neighborhood memory. We would argue that routes around historical places in Carabanchel, as well as the “Three Wise Men” popular parades in Hortaleza bring shared geographical imaginaries, collective memory, and iconic places together in everyday experiences of both places. These itineraries change both urban sites in terms of their neighborhood heritage by disputing spatial discourses and imaginaries of heritage, urban place, and neighborhood.
