TL;DR: In this article, the authors present an exploratory case study to identify potential applications of visual assets obtained from UAVs for construction management tasks, including project progress monitoring, job site logistics, evaluating safety conditions, and quality inspections among other secondary management tasks.
Abstract: Despite studies exploring potential applications of unmanned aerial systems (UASs), the particular use and value of visual assets (photographs or video) collected with UASs for construction management tasks is not well understood. This paper presents an exploratory case study to identify potential applications of visual assets obtained from UASs for construction management tasks. The case study involved the development of a visual assets database from UAS-based images and videos collected during UAS flights at jobsites in the United States and Brazil as well as semi-structured interviews with construction project personnel. The results revealed potential applications of UASs mainly for project progress monitoring, job site logistics, evaluating safety conditions, and quality inspections among other secondary management tasks. In addition, an analysis of costs related to the use of UASs was performed. The main contribution of this case study is a better understanding of the use of UASs for construction management tasks and their regulatory and cost implications.

TL;DR: The research findings validate the positive impact of real-time, accurate, and cost-effective automated progress monitoring environments and reveal how automated progressmonitoring affects construction project success.
Abstract: Despite recent advances in technologies and equipment for automated progress monitoring, most construction companies worldwide do not utilize them for their projects. This can be due to many reasons, such as the high cost of technologies and equipment, need for skilled staff, and lack of sufficient information about the impact of automated progress monitoring on project performance control. The aim of the present research is to investigate the impact of automated progress monitoring on key project performance indicators: time, cost, and quality. This study prepared based on a survey of contracting and engineering consulting firms in North America, Europe, and the Middle East. In the first part of this study, structural equation modeling is used to identify the relations of different factors of project progress monitoring (both conventional and automated) with project performance control. In the second part of the study, a benefit analysis is evaluated based on the sixteen (16) journal and international conference papers and also twenty-four (24) international construction projects for which automated progress monitoring was employed. The research findings validate the positive impact of real-time, accurate, and cost-effective automated progress monitoring environments and reveal how automated progress monitoring affects construction project success.

TL;DR: The four major uses of UAVs, including their use in construction, the potential risks of their use to workers, approaches for risk mitigation, and the important role that safety and health professionals can play in ensuring safe approaches to the theirUse in the workplace are described.
Abstract: Applications of unmanned aerial vehicles (UAVs) for military, recreational, public, and commercial uses have expanded significantly in recent years. In the construction industry, UAVs are used primarily for monitoring of construction workflow and job site logistics, inspecting construction sites to assess structural integrity, and for maintenance assessments. As is the case with other emerging technologies, occupational safety assessments of UAVs lag behind technological advancements. UAVs may create new workplace hazards that need to be evaluated and managed to ensure their safe operation around human workers. At the same time, UAVs can perform dangerous tasks, thereby improving workplace safety. This paper describes the four major uses of UAVs, including their use in construction, the potential risks of their use to workers, approaches for risk mitigation, and the important role that safety and health professionals can play in ensuring safe approaches to the their use in the workplace.

TL;DR: In this paper, the application of UAVs for visual inspection and damage detection on civil structures is discussed and the properties of such flight systems, the factors influencing their movements and the resulting photo quality is discussed.
Abstract: This paper discusses the application of Unmanned Aerial Vehicles (UAV) for visual inspection and damage detection on civil structures. The quality of photos and videos taken by using such airborne vehicles is strongly influenced by numerous parameters such as lighting conditions, distance to the object and vehicle motion induced by environmental effects. Whilst such devices feature highly sophisticated sensors and control algorithms, specifically the effects of fluctuating wind speeds and directions affect the vehicle motion. The nature of vehicle movements during photo and video acquisition in turn affect the quality of the data and hence the degree to which damages can be identified. This paper discusses the properties of such flight systems, the factors influencing their movements and the resulting photo quality. Based on the processed data logged by the high precision sensors on the UAV the influences are studied and a method is shown by which the damage assessment quality may be quantified.

TL;DR: In this study, a small-scale aerial drone was used as a tool for exploring potential benefits to safety managers within the construction jobsite and recommendations for the required features of an Ideal Safety Inspection Drone were led.
Abstract: SUMMARY: The construction industry lags behind many others in the rate of adoption of cutting edge technologies In the area of safety management this is more so Many advances in information technology could provide great benefits to this important aspect of construction operations Innovative use of these tools could result in safer jobsites This paper discusses initial application of drone technology in the construction industry In this study, a small-scale aerial drone was used as a tool for exploring potential benefits to safety managers within the construction jobsite This drone is an aerial quadricopter that can be piloted remotely using a smart phone, tablet device or a computer Since the drone is equipped with video cameras, it can provide safety managers with fast access to images as well as real time videos from a range of locations around the jobsite An expert analysis (heuristic evaluation) as well as a user participation analysis were performed on said quadricopter to determine the features of an ideal safety inspection drone The heuristic evaluation uncovered some of the user interface problems of the drone interface considering the context of the safety inspection The user participation evaluation was performed following a simulated task of counting the number of hardhats viewed through the display of a mobile device in the controlled environment of the lab Considering the task and the controlled variables, this experimental approach revealed that using the drone together with a large-size interface (eg iPad) would be as accurate as having the safety manager with plain view of the jobsite The results of these two evaluations together with previous experience of the authors in the area of safety inspection and drone technology led to recommendations for the required features of an Ideal Safety Inspection Drone Autonomous navigation, vocal interaction, high-resolution cameras, and collaborative user-interface environment are some examples of those features This innovative application of the aerial drone has the potential to improve construction practices and in this case facilitate jobsite safety inspections

TL;DR: In this paper, the authors describe the vision-based control of a small UAV following a road, using only the vision measurements and onboard inertial sensors, using a control strategy stabilizing the aircraft and following the road.
Abstract: This paper describes the vision-based control of a small autonomous aircraft following a road. The computer vision system detects natural features of the scene and tracks the roadway in order to determine relative yaw and lateral displacement between the aircraft and the road. Using only the vision measurements and onboard inertial sensors, a control strategy stabilizes the aircraft and follows the road. The road detection and aircraft control strategies have been verified by hardware in the loop (HIL) simulations over long stretches (several kilometers) of straight roads and in conditions of up to 5 m/s of prevailing wind. Hardware experiments have also been conducted using a modified radio-controlled aircraft. Successful road following was demonstrated over an airfield runway under variable lighting and wind conditions. The development of vision-based control strategies for unmanned aerial vehicles (UAVs), such as the ones presented here, enables complex autonomous missions in environments where typical navigation sensor like GPS are unavailable.
