Abstract : This dissertation, at the crossroads of urban studies and the sociology of professional groups and expertise, explores the characteristics of a group of experts in sustainable development engaged in the processes of urban production in the 2010s. This work is based on an ethnographic study of the activity of a team of about twenty specialists working at Alpha, a multi-specialized and international urban engineering company that is part of a broader urban services business. My work shows that the existence of this group of experts, its journey, and its structuring features fundamentally reflect its members’ ability to address the ambiguities of sustainable development in order to maintain and reformulate a diversified need for expertise (consulting services, study reports, urban foresight, tool development). Thus, they take care of a multidimensional problem within the company and conquer new markets of urban expertise. The differentiated appropriation of sustainability principles in these activities reflects the dynamics of legitimization between experts and other actors in the professional worlds of urban engineering, consulting and urban planning and design. The delimitation and extension of the experts' professional jurisdiction requires that they constantly perform a balancing act which both underscores the uniqueness of their skills and of the knowledge, and the diversity of their professional fields. These results were collected from 2013 to 2018 from the position of a practitioner researcher. This dissertation thus contributes to identifying both the processes through which of a group of actors (re)-positions themselves at the heart of the urban fabric and the ways through which the outlines of sustainable development are renewed.
