Aplicação de um engenheiro de registro (EDR) em barragens de acúmulo de água: benefícios na segurança

Abstract

Modern society depends heavily on the supply of water in abundance and with quality, for which dams are usually built. These constructions normally attract human occupation in their downstream regions. In this way, it is evident that the rupture of these structures puts the lives of local populations at risk, hence the importance of their security. Dam safety strongly depends on the organizational structure, the entrepreneur's philosophy and the technical responsibility of the actors involved. In this sense, this research sought to: present the concept of the Engineer of Record (EoR); its influence on continuous safety improvement; propose a work plan for this professional, applied to water accumulation dams, and; estimate the costs associated with your team. To this end, a survey was carried out of the Brazilian legislation focused on the safety of mining and water accumulation dams. A study was also carried out on the guidelines and safety parameters of dams in an international context, the history and application of EoR and, finally, the condition of water accumulation dams in Brazil. As mining dams have been through recent accidents, the laws and safety methodologies for these are stricter. Thus, in the light of this experience, a list of actions was proposed for the EoR for water accumulation dams, divided into two stages, the first to comply with the National Policy on Dam Safety, and the second for the continuous improvement of safety. of the structure, in addition, an estimate was made, reaching the value of R$ 0.13 per m³ consumed for the implementation of an EoR team.
