Dificuldades e encontradas na execução de obras de saneamento em centros urbanos: análise conceitual e estudos de caso

Abstract

The current study, developed from the analysis of two concrete cases, sheds light on two problematic issues which are well known by all but that have been dealt with inefficiently in order to avoid them: delays in delivery deadlines and huge budgetary alterations in sanitation works in urban centers. Such issues are derived from the difficulties found during the execution of these works, and have its origin in isolated or combined actions of several relevant factors, of social, technical, environmental, meteorological, geological nature and others, not forecast in theprojects and budgets. With the purpose of contributing for the reduction of the influence of these factors, some preventive procedures of fundamental significance, in the end, have been identifies to balance, as unique objective, the social and economis development in order to preserve the environment and the human species.
