Investigação de manifestações patológicas: estudo de caso em condomínio residencial multipavimentos

Abstract

A building aims, among other purposes, to ensure the safety and comfort of its occupants. However, the lack of skilled labor and the use of materials without quality control result in pathological manifestations, compromising the building’s functions and consequently causing customer dissatisfaction. A pathological manifestation is the technical term used to refer to any anomaly, defect, or problem that appears in a building, indicating that something is not functioning as it should. The focus is to ensure that buildings meet established quality and durability standards, guaranteeing their overall functionality. Thus, this study conducted a qualitative and quantitative investigation of the main pathological manifestations in a multi-story residential condominium located in Guarapuava, Paraná, Brazil. A total of 817 technical assistance requests were analyzed over two years, of which 590 were considered valid. Of these, 87% were attributed to workmanship failures or technical execution errors, and 13% to problems with materials. It was identified that 75% of the occurrences are concentrated in four groups of construction systems: finishes and coverings (39%), plumbing installations (18%), concrete subfloors/flooring (11%), and prefabricated equipment (7%). The most frequent pathologies included masonrycracks, water infiltrations, ceramic tile detachment, and watertightness failures in window frames. The cost estimate indicates that approximately R$ 1,284,580.00 were spent on corrective maintenance that could have been avoided with better training, proper material specification, and qualified execution. Finally, the study applied the GUT matrix to prioritize the critical cases, reinforcing the importance of preventive measures and strict quality control throughout all phases of the construction process.
