“…After reviewing and comparing the results, it was concluded that DT and ANN had better performance compared to the low performance of SVM. It was also concluded that ANN is widely used when it comes to predictions in infrastructure, but DT is more promising in terms of speed [ 58 ]. Microwave NDE was used to investigate the structural health of coated/uncoated metallic or dielectric materials.…”

Inspection methods, also known as non-destructive evaluation (NDE), is a process for inspecting materials, products, and facilities to identify flaws, imperfections, and malfunctions without destruction or changing the integrity of materials, structures, and mechanisms. However, detecting those defects requires test conducting and results inferring, which is highly demanding in terms of analysis, performance, and time. New technologies are therefore needed to increase the efficiency, probability of detection, and interpretability of NDE methods to establish smart inspection. In this context, Artificial intelligence (AI), as a fundamental component of the Industry 4.0, is a well-suited tool to address downsides associated with the current NDE methods for analysis and interpretation of inspection results, where methods integrating AI into their inspection process become automated and are known as smart inspection methods. This article sheds a light on the conventional methods and the smart techniques used in defects detection. Subsequently, a comparison between the two notions is presented. Furthermore, it investigates opportunities for the integration of non-destructive evaluation (NDE) methods and Industry 4.0 technologies. In addition, the challenges hindering the progress of the domain are mentioned as the potential solutions. To this end, along with Industry 4.0 technologies, a virtual inspection system has been proposed to deploy smart inspection.

Abstract. The paper is focused on the results of the survey and diagnostics of the bridge № M 044 at the end of Rybničná street above the road II/502 Bratislava-Pezinok in the Slovak Republic. The article is the result of the cooperation between the Department of Concrete Structures and Bridges of the Slovak Technical University in Bratislava and the Department of Reinforced Concrete Structures and Transport Facilities of the Odessa State Academy of Civil Engineering and Architecture within the framework of the National Scholarship Program of the Slovak Republic. Data were obtained to assess the technical condition of the structures and the bridge as a whole. As a result of the inspection, the type of destruction of each structural element of the frame and superstructure was determined. A study on the content of chloride-ionic contamination of concrete and non-destructive tests of strength parameters was carried out. A detailed research analysis of the results and recommendations for processing the reconstruction has been proposed. In accordance with the valid regulations, due to the significant deformation in the horizontal plane, the cause of which is not known and due to the gradual loss of the bearing function, we evaluate the construction, and technical condition by the degree: VI ‒ very bad, and immediate reconstruction is required. The service life of the bridge is mainly affected by corrosion and displacement of the bearings, as well as contamination of concrete with chlorides from sanding salts and corroded bearings. Corrosion of the reinforcement in the horizon of 5 years can negatively affect the load-bearing capacity of the bridge and there is also an increased risk of falling pieces of the covering layer of the reinforcement on the road leading under the bridge. The following actions are strongly recommended: replace all bearings; reconstruct the waterproofing of the bridge, roadway, drainage system, expansion join on support no. 4; consider the installation of asphalt expansion joins over support no. 1 and piers no. 2 and 3; clean the entire surface with high-pressure water and apply a remedial coating, that would slow down the corrosion of the reinforcement; renew the areas with the delaminated cover layer with a repair compound. The conclusions about the calculation of load bearing capacity are based on the current technical condition of the bridge found during diagnostics (08/2021). During further operation, it is necessary to pay attention to the state of prestressing and possible opening of joints at the contact of beam segments.

“…At present, 3D laser scanning technology has been gradually applied to engineering construction [3][4] . The measured building point cloud data can clearly represent the three-dimensional space information of buildings, and provide high-precision, highdensity building surface description [5][6] [7] . This paper presents a non-contact measurement method for geometric parameters of bridge structures based on 3D laser scanning technology.…”

Bridge engineering construction is a kind of engineering construction with high risk. Only by building scientific and reasonable safety assessment and monitoring measures can the construction safety be improved and the risk be controlled. Based on the construction of a large cantilever steel truss traffic bridge project, this paper introduces the application of three-dimensional laser scanning technology in the monitoring of bridge transverse construction from the aspects of measuring point layout, monitoring scheme, scanning measurement and data analysis and processing. This paper introduces the bridge construction safety monitoring technology, as well as the content and steps of construction safety monitoring, and summarizes the measures of bridge construction safety assessment monitoring.
