People tracking: locating workers on a construction site
Dragage Singapore, a subsidiary of the Bouygues Construction group, has placed its trust in ELA Innovation, Omniscient and Wirepas to secure and optimize the Glory Tower construction site. To meet this challenge, an indoor location solution in Mesh network has been deployed. The challenge was huge, in fact it was necessary to be able to locate 1800 workers in real time on the construction site of the second largest tower in Singapore consisting of 51 floors. Omniscient, supervised the deployment of the solution, which was completed in less than 2 months, and also provided the business software platform. ELA Innovation delivered the tags to locate the workers. Wirepas, publisher of the Mesh software brick, brought its expertise in setting up the network infrastructure, as well as its Wirepas Positioning Engine localization solution.
We chose the Blue PUCK ID+ Mesh from ELA Innovation because it offered a good compromise between size, autonomy, robustness and a guarantee of IP68 waterproofing, which is essential for deployment on a construction site. The tag's ability to send a signal in case of displacement was also an asset.

Technical Operation
From a technical point of view, the localization solution is based on an extremely light infrastructure made up of fixed tags called anchors. These anchors, entirely battery-powered, offer a mesh communication network with autonomy of several years. In this project, only 9 anchors were needed per floor of 2,100m². 1800 mobile tags2 were then distributed to the workers, enabling them to be located at regular intervals. The mobile tags communicate with the platform thanks to the mesh network of anchors, connected to the cloud via 9 Gateways ensuring the connection between the local network and the cloud.
The raw data collected by the tags are transformed into GPS data (latitude and longitude) by the Wirepas Positioning Engine and are then visualized on the Omniscient business web application. This IoT platform has been developed to meet the needs of the construction industry. It allows to visualize in real time the workforce by floor, by trade and by subcontractor. The Omniscient application offers the possibility to switch in one click from a plan view to a sectional view of the building. A true decision-making tool, the dashboard provides factual information on the organization of the construction site and facilitates arbitration and decision-making.
