Análise das principais manifestações patológicas no edifício do Teatro do IFG – Campus Goiânia utilizando técnicas com VANT e termografia infravermelha.

Abstract

Pathological manifestations are flaws that occur in buildings, compromising their functionality, integrity, durability, and performance. These irregularities can be recurrent and result from a variety of factors, such as execution errors, design flaws, poor material quality, and adverse environmental conditions. To identify and evaluate them, building inspections are conducted, ranging from empirical analysis to the use of specialized equipment and specific tests. In this context, this study aimed to identify, map, and classify the main pathological manifestations present in the Theater of the Federal Institute of Education, Science, and Technology of Goiás – Goiânia Campus. The internal inspection was performed visually, using equipment such as a percussion test rod, tape measure, flashlight, and crack meter. For external areas, such as the north facade and roof, the use of an Unmanned Aerial Vehicle (UAV) was incorporated, enabling detailed mapping of irregularities through image capture, facilitating the identification of problems in hard-to-reach or hard-to-see locations. Furthermore, infrared thermography was applied, a technique that detects thermal variations on the building's surface through colorimetric images, enabling the identification of leaks and other moisture-related damage. This approach aims to ensure a comprehensive assessment of the theater's conservation status. Built in the 1940s, the Main Auditorium reopened in November 2011, it boasts significant historical and cultural significance and is a listed building by the National Institute of Historical and Artistic Heritage (IPHAN). Therefore, it is essential that this building receive the necessary care to preserve its original features and the principles that justified its listing.
