Análise das manifestações patológicas causadas por uma unidade primária de tratamento de esgoto: uma perícia judicial realizada em Belo Horizonte

Abstract

This work proposes to conduct a case study concerning a judicial investigation carried out in a neighborhood of Belo Horizonte. The aim of this study is to analyze the defects in construction materials caused by chemical reactions. The objects of the expert’s report are a property boundary wall and a primary unit of sewage treatment in a unstable state causing disturbances in the adjoining land. Limited information was found for further research as there was not enough detail of the original work performed, such as records of composition and formulation, and structural dimensions. A bibliographic survey will follow elaborating the main concepts for understanding the subject matter of the investigation, using personal expertise, and documentation, specifically concerning the manifested material defects, in order to obtain a theoretical basis for investigating how those manifestations developed. Although the objects of the study were in an altered state, through the investigation it was possible to apprehend how those objects were actually constructed. The boundary wall was in an unstable condition with signs of infiltration by the primary unit of sewage treatment, which, like the wall, was also in an unstable condition. In addition, it was observed that this unit is not in compliance with current legislation, as the streets around the surrounding the properties have adequate sewage pipes for correct disposal. Even so, it is possible to conclude that laws defining building codes, technical standards, etc., in the field of civil construction, it is common for buildings to be built without technical supervision, neglect with the care of the built environment and even disrespect. the legislation that governs the area. In other words, the problem is not only in the constructive technique, but also in deviations from the human character. Regarding the case study in question, we highlight the lack of design, non-compliance with the obligation to use the sewage system present in both roads and the lack of care with maintaining the built environment.
