The facade maintenance process is guided by the results obtained in the inspection phase. Some proposals for methods aimed at improving the inspection process have been discussed, and among these, those that are conducted based on Digital Image Processing (PDI) techniques captured by Unmanned Aerial Vehicle (UAV) stand out. The use of UAVs to capture images on facades streamlines access to the inspected area, and PDI techniques help to automate the process of identifying pathological manifestations. In addition, the fourth industrial revolution has allowed the use of various technological tools in the most varied engineering applications. Among these technologies we can mention cloud computing and computer vision algorithms. In this context, this research aims to apply PDI techniques to detect regions with ceramic displacement on building facades using technologies relevant to industry 4.0 (fourth industrial revolution). The methodological procedure used starts with the formation of a database (images) captured by cell phone and UAV. For modeling purposes, the YOLO (You Only Look Once) object detection algorithm was applied to the images that make up the database using cloud computing. The applied methodology resulted in a program written in python capable of identifying the regions with displacement, quantifying the missing ceramics and exporting the quantification results in a spreadsheet. The identification process had success rates close to 99% and the quantification errors of less than one ceramic per image, which leads to the conclusion of the feasibility of the proposed computational program

Ensuring safety and reliability in dams is a challenge for society, governments and especially for entrepreneurs who experience daily difficulties in maintaining the enterprise in good conditions of use during its life cycle. Today, technology is an indispensable tool for this to happen in view of the continuous need for the development and application of this tool in this branch of engineering. Thus, in order to contribute to the dam inspection process, the present work brings a proposal that innovates in the way the information is collected bringing the possibility of replacing the filling of a check list in a manual and traditional way to an automated way through a platform. simple and intuitive. This platform consists of an Android application. To do so, it was necessary to analyze the entrepreneur's manual on dam safety - volume II of the National Water Agency, study about mobile application development and define the application's functionalities to develop it. Then, studies were carried out on the programming language and the software for developing the tool on Android. One by one, the features of the App were built using a peculiar methodology for this, which revolves around the gear made up of research, testing and implementation. The developed application, called ISB, is a test version and has been subjected to emulations to verify its operation. Therefore, it was found that the application performed satisfactorily, avoiding flaws in the filling, and therefore in the safety assessment of the works surveyed.
