Analysis of pathological manifestations through damage map: case study in Buildings I and K of the Polytechnic School of Pernambuco

Abstract

Building inspection in constructions is important to verify that the building is in good safety condition for its occupants, identify problems that harm people's comfort or even determine preventive maintenance to avoid problems early, helping to extend the life of the building. One of the ways to document the condition of a building is through the damage map. The objective of this article is to present the survey of the existing pathological manifestations on the facades of Buildings I and K of the Polytechnic School of Pernambuco, representing them using damage maps to contribute to the maintenance and restoration services of the analyzed buildings. To this end, the architectural survey of the facades of Buildings I and K was carried out, the photographic survey was done using smartphone and drone and finally, the creation of the damage map. With the analysis of the results, it was noticed the presence of 14 pathological manifestations, where the most recurrent were grime and efflorescence. The front and right lateral facades presented the highest and lowest number of pathological manifestations, respectively. With the periodic survey of the pathological manifestations and their representations in damage maps it will be possible to create an evolution chart of the state of Buildings I and K and plan future preventive and/or corrective maintenance.
