Its primary objective is to ensure the safety and optimal performance of these structures. This undertaking involves the abstraction and interpretation of extensive structural, hydraulic, and geotechnical data, typically acquired through sensor networks embedded within the dam. This study introduces 'DamVR', a virtual reality tool for situated dam safety control data visualization. This tool allows dam engineers and other industry professionals to analyze the fluctuation of structural behavior over time. Its immersive environment contains a realistic representation of the dam structure, networks of sensors, and surroundings. It aims to frame the data within the visual context of the object of the analysis. This contextualization is intended to improve analytical reasoning and decision-making. The usability of DamVR was evaluated by a group of domain experts and compared to an existing augmented reality tool in similar tasks. The results indicate that DamVR is a usable and effective dam safety control data visualization tool.}, doi={10.1109/ICGI60907.2023.10452725}}

However, it does not take full advantage of the latest advancements when it comes to in-situ, real-time, information visualization. This work explores the application of Augmented Reality to the inspection and monitoring of large Civil Engineering structures, namely concrete dams. The proposed approach focuses on offering new visualization possibilities, that are not accessible through traditional means, to Dam Safety Control. In that scope, it depicts the specification and development of a proof-of-concept prototype that allows the monitoring of relevant structural-related information in an Augmented Reality environment. In particular, it offers an easy and straightforward way for Civil Engineers and Observation Technicians a mean to access data from the network of sensors situated in the downstream face and the interior of the structure. Besides providing insightful information on the current status, it allows exploring the evolution in time of values registered in each sensor. A preliminary study aimed at validating the proposed approach shows that Augmented Reality technologies can be used efficiently in Dam Safety Control.} }

The traditional techniques, which use archaic instruments for positioning and tracking, continue to be massively used. Although there are a few technologically advanced solutions available, in general these involve very expensive equipment, can only be used in conjunction with an inspection vehicle and, therefore, do not enclose the level of versatility needed in most cases. In addition, these solutions are not practical for inspecting highly trafficked intersections, especially when some level of detail and precision are needed. Furthermore the office work required to organize the extensive raw data collected in the field, by traditional means, is considerable. It often involves several time-spending stages in the treatment of the data records, which can lead to errors and imprecision, before it can be available for analysis and interpretation. It is urgent to adopt more effective and versatile methods that are both economically and technically proficient and also more sustainable without the substantial costs in manpower, time and energy. The purpose of this work is to present an ongoing research focused on creating an integrated system to aid the visual inspection and characterization of pavements and manage its state of preservation. The premises of this development implied that the system should use state-of-the-art technology (in both hardware and software), allow a high level of detail in the characterization, be manifestly low-cost, user-friendly, portable and ready to be used on-foot or installed in a vehicle, significantly reduce the time and means involved in the field work, decrease the number of phases in the handling of the field data and efficiently manage the condition of the pavement. Starting with the experience acquired in practical cases where detailed pavement inspection and characterization took place, namely a section of the A1 portuguese motorway, a comparison between the means involved in the use of traditional methods and the use of this new system, will be made. In addition the several pavement pathology classification criteria available nowadays and the way this system deals with it, will be shown. Finally the repercussion that the commercialization and generalized use of this type of low-cost systems can have in the quality of the results and in the reduction of material and human resources will be discussed.} }
