Volan provides virtual, geofenced barriers for airport construction sites to keep workers out of restricted areas. Airport construction projects are never-ending, have many workers, and regulations require full-time monitoring of worker location. Volan’s barrier technology can provide alerts within 2-3 seconds if a worker moves into a restricted space, along with the precise location of the worker and a live map view. The current method of using human escorts at airports is expensive and error-prone. Airports can save overhead costs by reducing the number of security guards and worker escorts that are needed. $1,000,000 is the estimated cost of escort labor for a single project at a major US airport.
