Estudo de caso: levantamento das patologias em fachadas de habitações populares e sua influência na perda de valor das edificações

Abstract

Pathologies have been found in buildings, motivated by a series of factors, such as failures in projects, being human and of execution, ignorance and the use of materials of inferior quality to the real necessity, and limited term of delivery. Buildings that present pathologies present a loss of value, due to the presented aspects, such as the problems that require maintenance and corrective measures. In this sense, the work presents the survey of pathologies occurring in the façades of the Jardim da Mata housing complex, located in Toledo Paraná, composed of 315 residences. The data collection was carried out in 92 buildings, where the in situ pathologies were identified for each of the faces of the buildings. These pathologies were explained by means of the damage map, which shows the location of each type of pathology. The results indicated the most frequent pathologies, that is, cracks mapped (98.91%), paint spots (76.09%) and mold (63.04%). The work still presents the current value of the buildings, due to their state of conservation, which is associated with the presence of pathologies. In this way, three values were obtained, as a function of the three conservation states found in the data sample, if, R$ 91,671.53; R$ 87,527.94 and R$ 80,084.17. Therefore, the loss of value of the houses analyzed was R$ 4,190.55; R$ 8,333.14 and R$ 15,777.91, respectively, for the buildings that have only four years of use, analyzing only the pathologies of the facades and having been made reforms in all the buildings analyzed during the period of use.
