“…Drones are mainly used in hard-to-reach locations. Jensen [19] mentions that, with video images, it is hard to locate each observation due to the comprehensive size of the structure and presence of very similar surfaces. Another form of inspection can be conducted from photos or videogrammetry, equipped on a drone, with the digital generation of high-resolution image data of the structural surface, enabling the estimation of motion and constant imaging properties from a single camera, from the identification of image points, calculation of initial image geometry and 3D point clouds geometry.…”

“…Anomaly detection can be conducted from a 3D model imported along with the imagery as presented by Jensen [19] in Figure 3, or by applying using the imagery from photogrammetry (Morgenthal et al [14]), shown in Figure 4. According to Jensen [19], COWI, an international consulting group specializing in engineering, environmental science, and economics, has developed a web-based tool called COWI Virtual Inspection (CVI).…”

Studies have shown a worrisome condition as to the conservation of Civil Engineering Structures (CESs) in Brazilian highways. This situation mainly results from the lack of an efficient system for managing such structures, specifically during their operational stage, when periodic maintenance is required. As a solution, the Bridge Information Modeling (BrIM) has proven to be an efficient system for managing CESs, integrating different technologies into this process. The purpose of this paper is to assess how BrIM can contribute to improve the management procedures of these structures. The research methodology has been divided into two stages. The first one is the literature review detailing the management scenario of CESs in the country, as well as the analysis of the BrIM used as a tool to manage such structures in a general context. The second stage is a case study addressing the operational and maintenance process of CESs used by a highway concessionaire in an important Brazilian state. The analysis concluded that, although recent, the adoption of BrIM has been growing in several countries, and it can substantially contribute to improving the operational and maintenance stages of CESs.

“…There have been numerous studies related to the health monitoring and maintenance of bridges by using BIM models [ 204 , 205 , 206 , 207 , 208 , 209 , 210 , 211 , 212 , 213 , 214 ]. Combining BIM with other programs such as GIS improves the process of monitoring and risk or damage analysis [ 215 , 216 ].…”

Improvements in the science of health monitoring and maintenance have facilitated the observation of damage and defects in existing structures and infrastructures, such as bridges and railways. The need to extend sensing technology through the use of wireless sensors as well as the lack of description tools for understanding, visualizing, and documenting sensor outputs has encouraged researchers to use powerful tools such as Building Information Modelling (BIM) systems. BIM has become important because of conducting tools widely used in the Architecture, Engineering, and Construction (AEC) industry to present and manage information on structural systems and situations. Since combining health monitoring and maintenance results with BIM models is a new field of study, and most projects utilize various aspects of it, we have conducted a review of important work related to this subject published from 2010 to November of 2020. After reviewing 278 journal articles, research trends, approaches, methods, gaps, and future agenda related to BIM in monitoring and maintenance were highlighted. This paper, through a bibliometric and content analysis, concludes that besides main improvements, some limitations now exist which affect the modeling and maintenance process. These limitations are related to extending the IFC schema, optimizing sensor data, interoperability among various BIM platforms, optimization of various sensing technologies for fault detection and management of huge amounts of data, besides consideration of environmental effects on monitoring hazards and underground objects. Finally, this paper aims to help to solve the mentioned limitation through a comprehensive review of existing research.

“…[4,5]. At present, bridge monitoring methods mainly include manual regular inspection, cable laying monitoring, machine vision measurement, three-dimensional laser mapping, and other methods [6,7]. However, traditional manual intermittent inspection methods, such as deflection metres and three-dimensional laser mapping, have poor real-time performance, low efficiency, and a low degree of automation [8].…”

Bridges are a kind of infrastructure constructed to save urban space, to relieve traffic congestion, and to show urban modernisation. Therefore, bridge safety has become the focus of social attention. To know the structural condition of the bridge in real‐time, it is necessary to develop an intelligent and efficient bridge health monitoring system. However, the traditional bridge health monitoring system has poor real‐time performance, low efficiency, and a low degree of automation. The development of LoRa technology is expected to improve this situation. In this study, we designed a bridge‐distributed monitoring system based on LoRa technology, which has end nodes, relay nodes, a collect node, and a monitoring centre. In detail, the STM32H743XI processor is combined with the radio frequency SX1268 chip to form the above nodes. Furthermore, the end node contains the pulse vibration excitation circuit, and pick‐up signal conditioning circuit of the vibrating string crack metre, and the signal conditioning circuit of the temperature sensor AD590 and the humidity sensor HM1500LF. Finally, the data preprocessing of sensors and the communication performance of the two‐stage relay network of the LoRa module, which represent the key technologies to effectively and efficiently meet the real‐time monitoring of bridge conditions, are tested and discussed. This distributed monitoring system for the bridge can provide feasible solutions for the application field of bridge monitoring, which is helpful for the daily maintenance management and risk warning decision‐making of bridges.
