Intelligent Construction Site: On Low Cost Automated Indoor Localization Using Bluetooth Low Energy Beacons

The construction jobsites are highly dynamic environments involved with labor-intensive and manual tasks that suffer from inefficiency and mis-management. To remedy these issues, production control within the scope of lean construction has been a hot topic in academia and industry. To this end, we have developed a real-time coordination-based tracking system using low-cost Bluetooth Low Energy beacons. This system is implemented according to the trilateration method in order to acquire the real-time location of resources and movement trajectory in the construction jobsites. The prototype is tested and implemented in the real construction site in China. The results show that the implemented tracking system can be used in the construction sites depending on the accuracy level required in the project.
