Investigating the Safety Challenges of Unmanned Aerial Vehicles (UAVs) in the Construction Environment
(East Carolina University, 2021-12-01) Khalid, Mohammad
The technologies associated with Unmanned Aerial vehicles (UAVs) have revolutionized the construction industry, simultaneously demanding a comprehensive understanding of the underlying safety implications in order to reduce the risk of personal injury, property damage, lost productivity, and financial damage. Construction is one of the most hazardous sectors, with a wide range of complexity inherent in the nature of its activities, and widespread integration of UAVs without adequate safety management expertise, training, and strategies may exacerbate existing hazards. An increasing volume of research is being conducted on the potential benefits of UAV utilization. However, there is a scarcity of knowledge and development of UAV-based safety frameworks, which might have an impact on the construction sector in the near future. This study aims to investigate the potential safety risks presented by UAV use in the construction environment. In the lack of quantitative and structured data on the effects of UAV-related incidents in the construction environment, the workforce is exposed to an array of unwarranted safety risks. The data was collected through a questionnaire survey that was constructed by a series of designed questions to provide quantitative results in a context aligned to the original research goal. The findings identify a variety of potential and actual risks associated with UAV integration, as well as a substantial perception difference concerning UAVs across industry practitioners. Collision with person and property, trespassing, system malfunction, and inexperienced pilot are the safety risks of high importance with high potential to cause substantial damage and halt productivity. The study further created a construction-specific UAV safety training program that addressed the identified risks and hazards, with the goal of increasing familiarity with UAV uses in conjunction with construction dynamics. Adopting the research study's results and improvements would allow construction practitioners to rapidly detect UAV-based safety concerns with the help of special training and excel in construction safety performance without compromising productivity.
Impact of the COVID-19: Hazard Recognition Performance and Safety Risk Perception Among Construction Workers
(East Carolina University, 2022-04-29) Nabil, Fahim Ridwan
The construction industry is one of the most hazardous industries in the U.S., and COVID-19 has introduced additional safety risks to the workers' health and safety. Fatalities in the construction industry are higher compared to others. Researchers have identified construction workers' poor hazard recognition performance and safety risk perception as contributing factors to the high rates of accidents and occupational fatalities in construction. However, the long-term impact of COVID-19 as an emerging safety risk on construction workers' hazard recognition performance and safety risk perception has not been investigated. This study aimed to explore the long-term impact of COVID-19 on construction workers' hazard recognition and safety risk perception. The goal is to see if COVID-19 has the same effect on workers' performance as a physical injury and how their performance changes after experiencing COVID-19. Seventy-six workers were interviewed during the study. Each participant was shown four scenarios from a predefined 16 preset construction scenario. T-test was performed to test the research hypotheses between groups (group 1: workers who have not tested positive for COVID-19 and group 2: workers who tested positive for COVID-19). For the first hypothesis, data analysis showed that COVID-19 did not affect the construction workers' hazard recognition as there was no statistical difference in the test. However, when the safety risk perception score was analyzed, it was observed that there was a statistical difference between the safety risk perception of the two groups. COVID-19 positive workers tend to perceive higher safety risks. The study aimed to aid in the improvement of the construction safety environment across the U.S. and help construction safety managers and trainers to have a better idea about the long-term impact of COVID-19 on the safety performance of the workers.
