Cost increase assessment in works of informal urban development areas

Abstract

In recent decades, investments in the development of informal low-income settlements occurred more frequently in areas that had received urban improvements. These projects have a number of factors that hinder interventions, such as the environmental fragility and the difficulty of access to areas of work. The objective of the research is to identify the feasibility of these interventions that aim to always keep people in their place of residence, considering as a limiting factor, environmental fragility, and high development costs. For the analysis are used the legal basis of low-income land tenure, which includes various dimensions and environmental rights. Also, it discusses social and environmental risks and their mitigation costs to contextualize the analysis. For costs assessment was used empirical method applied to the Jaburu community Project in Vitória-ES, which evaluated the degree of the executive design detail of the interventions, the construction techniques adopted and its implications on costs. In addition, a comparative analysis with the average cost of works in informal low-income settlements was made. As a result, it was found that the evaluated factors meant increases costs due to the difficulties of access and environmental fragility, supporting the premise that these can limit the right of the population to stay in these areas.
