Monitoring, in sleep mode, a park of structures known to be in good condition

Regular routine visual inspections on this park of structures are expensive and do not necessarily guarantee the total effectiveness of the safety arrangements. The client thus called upon OSMOS to monitor its structures in more detail, beyond simple visual criteria. Nevertheless, given the large number of structures to be monitored, only a financially viable solution could be envisaged. With just two Optical Strands per bridge, the client was able to benefit from total monitoring of its building park and receive confirmation that the bridges monitored were effectively structurally sound.
