Investigating the Role of Internet of Things (IoT) Sensors in Enhancing Construction Site Safety and Efficiency

The construction industry is one of the most hazardous and resource-intensive sectors, often facing challenges related to worker safety, operational inefficiencies, and project delays. The emergence of the Internet of Things (IoT) offers innovative solutions to address these issues by leveraging interconnected sensors, real-time monitoring, and data analytics. This study investigates the role of IoT sensors in enhancing construction site safety and efficiency. The research examines how IoT-enabled technologies, such as wearable sensors, environmental monitors, and asset-tracking devices, contribute to hazard detection, accident prevention, and resource optimization. A mixedmethod approach is adopted, combining case studies, interviews with industry professionals, and data analysis to evaluate the implementation and outcomes of IoT solutions on construction sites. Findings reveal that IoT sensors significantly improve safety by enabling real-time risk identification, worker tracking, and environmental monitoring. Additionally, IoT enhances operational efficiency through predictive maintenance, equipment tracking, and automated data-driven decision-making, resulting in reduced downtime and improved resource allocation. Despite the proven benefits, challenges such as implementation costs, technical integration, and user adoption remain significant barriers. The study concludes that IoT sensors play a pivotal role in modernizing the construction industry, offering substantial improvements in safety and efficiency. Recommendations for integrating IoT technologies into construction workflows are provided, alongside suggestions for future research to explore cost-benefit analyses and the integration of IoT with complementary technologies like Artificial Intelligence (AI) and Building Information Modeling (BIM).
