Top 10: IoT Devices for Construction

Construction sites generate constant streams of data, from equipment usage, to worker location to concrete curing times. It was not that long ago that all of that valuable data would go uncaptured. 

IoT devices have changed that, giving contractors real-time visibility into conditions that had to previously be tracked manually, if they were tracked at all.

These devices cover all aspects of the jobsite. Wearables monitor things like worker safety and gas exposure, while telematics platforms track equipment health and utilisation.

Sensors embedded in materials themselves are able to report back on structural readiness.

Construction Digital has ranked the Top 10 leading IoT devices and platforms used across construction today.
