Avaliação das manifestações patológicas em fachadas: um estudo de caso

Abstract

Pathological manifestations in civil construction can be extremely harmful to a building, especially when they receive no treatment, similar to a disease in a human being. In this context, the present work aims to obtain a diagnosis of the current situation of the facades of a building to assist in a future recovery process for the assessed elements. The chosen object of study was the building of the Municipal Administrative Center of Santa Maria. To assess the current situation of the building, on-site visits were conducted to identify and evaluate the different pathological manifestations present on the building's facade and to compile a survey of possible causes associated with them. The evaluation process was divided into three stages, with the first stage comprising the visual identification of pathological manifestations, the second involving the collection of images with the assistance of an unmanned aerial vehicle equipped with a high-definition camera, aiming to record the pathological manifestations and conduct a preliminary mapping of their presence. The final stage consisted of the preliminary assessment of possible causes, with this third stage being conducted through the comparison between situations observed during the assessment of pathological manifestations and possible causes found in the literature for the specific manifestations. This was done to identify which of these causes best fit the situation of the building. Through this process, it was possible to identify the pathological manifestations present in the building and propose their possible causes, leading to the conclusion that a lack of maintenance combined with errors in the project and execution may be the main contributors to the current state of the evaluated building.
