New Device Tracks Construction Workers Proximity, Interaction Times  

Construction Dive web site featured an article explaining the workings of Triax's Proximity Trace, a system that uses "trace tags" attached to construction workers’ helmets to track their proximity to each other and the duration of their interactions. By providing audible and visual alarms when workers come within close proximity to each other, the system reminds workers to properly distance on the worksite. In addition to actively alerting workers who are in close proximity, the tags collect worker interaction data and maintain a log of interactions with other tags as well as the duration of those interactions. Data made available in minutes can help track and therefore limit the spread of COVID-19.
