The French start-up CAD.42 is developing a tool for predicting danger and productivity management for construction sites. The solution, which collects position data from equipment and personnel, communicates in real time connected with PPE that warns of the imminence of a risky situation. And the high-visibility vest is a hazard prediction tool.
One in ten workers is injured every year in France. Based on this observation, the founders of the CAD.42 start-up have created a predictive hazard calculation system dedicated to construction sites, quarries and mines as well as the world of industry and energy. Jean-Philippe Panged, the co-founder and president of the entity created at the end of 2016, say that it amounts to “equipping the companions and the tools of very precise position sensors”. The data that are collected by these sensors are sent to the cloud and processed in real time to allow the detection of risk situations instantly.
A video shows the example of a worker working under a crane: “The smart safety vest detects the entry of the companion into the cone of danger, it triggers a warning light and sound”. In fact, the vest starts to sound and LEDs integrated into the reflective tapes produce flashes in order to attract the attention of the crane operator and the wearer of the connected EPI. The situation can also be viewed live on the digital model of the site manager. By positioning each element equipped with a beacon to within 30cm, it is possible to avoid machine-pedestrian collisions, to secure isolated workers and to dynamically mark risk zones in the case of simultaneous interventions.
