This study aims to characterize the changes in the urban city of Rio de Janeiro- RJ from the implementation of the Growth Acceleration Program (PAC). The space studied is the complex of slums called Manguinhos, that since 2008 has received assistance from the PAC. The goal is to identify strategies for the production of space sustainability and / or (in)sustainability that were produced during the intervention, with its central action of social actors involved in the process, aimed at building the right perspective of the city. The main theoretic frameworks used in the research were: Lefebvre (1974, 1986, 1991, 2002); Massey (2008); Ferreira (2007, 2011); Rua (2007), Morin (2002), Castoriadis (1987), Gohn (1997, 2008), Pogrebinschi (2009). Regarding the method, we walk through the historical dialectic materialism had to research procedures: a literature review, field research, questionnaires, and follow-up meetings organized by both the government and the representatives of social movements. It is noteworthy that the production of space is guided by models whose ideals stigmatize slums, perceiving them as if they belonged to the cities. We assume that the space produced in the cities is characterized by intense inequality, because this is the logic of capitalist development. Appealing to the concept of space in order to understand its production; the space being a social product, social relationships influence the dynamics, thus indicating intentions. The action of public authorities and social actors in Manguinhos is in the wake of this discussion, being representations that define and redefine this space production daily.
