The high frequency of work-related injuries and fatalities experienced on construction sites makes the construction process a very hazardous endeavor. The collection and analysis of safety data is an important element in measurement and improvement strategy development. Wearable sensing devices (WSDs) and the internet of things (IoT) have been identified as emerging technologies with strong potential for a transformative change in many aspects of construction workers safety monitoring including tracking and transmitting workers safety information in real-time. This paper provides an evaluation of the potential applications of WSDs and IoT for the continuous collection, analysis, and monitoring of construction workers’ safety metrics to mitigate safety hazards and health risks on construction sites. Wearable sensors and systems that can be used for physiological monitoring, environmental sensing, proximity detection, and location tracking of a wide range of construction hazards and vital signals which can provide early warning signs of safety issues to construction workers are reviewed. A schematic model for integrating wearable sensors for interoperability and multi-parameter monitoring to capture and track several safety metrics is also presented. The challenges facing the widespread adoption of WSDs and IoT in construction are also identified and evaluated. Based on the outcomes of the review completed, recommendations are made on how WSDs and IoT can be effectively implemented to enhance safety performance on construction sites.
