Proximity Trace Used to Monitor, Maintain Social Distancing on $1.9-Billion KCI Airport Project

In order to maintain social distancing on site, steel erector National Steel City of Plymouth, Mich., is using the Proximity Trace wearable sensor from Triax Technologies on the $1.9-billion Kansas City International Airport (KCI) single-terminal reconstruction project.

Proximity Trace tags are easily clipped to hardhats. “The alert goes off when two of the workers are within 6 ft of one another. They get a beep.

If they don’t move, the beep goes faster and then it doesn’t stop,” says Bob Dunn, CEO of National Steel City. “Triax had a relationship with United Rentals, who we’ve had an alliance of 20 plus years with. Within a very short period of time, they got information and the sensors to us and we were able to deploy them at the site.”

NSC crews have used the sensors since April as they installed 2,167 steel members and 172,000 sq ft of metal deck at KCI. The use of the Proximity Trace sensors is part of a site-wide safety protocol that National Steel City implemented based on Centers for Disease Control guidelines that includes sanitizing the workplace,maintaining distance, sanitizing tables during breaks and temperature checks for workers multiple times a day.
