Uso da geotecnologia RPA no acompanhamento de obras e projetos em diversas áreas da engenharia civil

Abstract

The use of geotechnologies in Brazil has gained ground in several areas of scientific knowledge, including in the scope of civil construction. In this context, Remotely Piloted Aircraft (RPAs), popularly known as drone, have assumed an important role in the use of geotechnologies in Civil Engineering, due to their functionality and relatively low cost. This work aims to show how RPAs can assist Civil Engineering, working in the areas of Land Survey, Facade Inspection and Construction Site Monitoring, making a comparison with traditional techniques regarding productivity, operational costs and accuracy. For that, a bibliographic review was made about the themes and a Market research in the city of Aracaju/SE. The study showed that in Land Surveys the use of Aerophotogrammetry with RPA was more practical and faster than the Total Station, in addition to having shown a cost reduction when compared. However, it provided centimeter accuracy, while the Total Station survey showed millimeter accuracy. When compared to the LASER scanner, it showed the same productivity and a 0.11% discrepancy in the accuracy for surveying the same area. In Facade Inspection, the use of RPA showed better productivity and lower cost, when compared to the conventional technique, however using RPA it is not possible to perform the percussion test, essential in some inspections. Finally, it was not possible to make a comparison of the techniques for Monitoring the Construction Site, nor to compare the costs of the LASER scanner, which are recommended for future studies.
