All Monitoring Data in One Platform
Management of three major bridges is simplified into one common data platform and made accessible though SAMS™ for complex analysis and enabling actionable decision making
Faced with the management of three long span bridges, The Chambre de Commerce et d’Industrie Territoriale Seine Estuaire (CCITSE) struggled with the control of six separate user interfaces for monitoring systems and needed to further expand their data collection.
The most prestigious bridge being the northern France landmark Pont de Normandie, stretching 2.1km across the Seine. At time of construction, the 856m main span was the world’s longest cable-stayed bridge span.
Basic structural health monitoring systems were historically fitted on each bridge, along with high-precision GPS monitoring systems, acoustic emission monitoring and meteorological stations. But CCITSE was dissatisfied with the ageing sensors and output of data without analysis, held on different servers and with different software for each system.
23 years after construction, many of the sensors originally installed were no longer functioning and a tender requirement was developed for a bridge consultant to provide actionable maintenance information from the data for all three bridges: Pont de Normandie (cable-stayed, opened 1995), Pont de Tancarville (suspension bridge, opened 1959) and Viaduc du Grand Canal (steel-composite viaduct, opened 1994).
JF Strainstall and specialist consultant COWI formed a collaborative relationship with CCITSE to deliver the optimal solution. Alongside COWI’s worldwide experience in cable supported bridges, JF Strainstall, as one of the world’s leading long-span bridge monitoring specialists, proposed our Smart Asset Management System, SAMS™.
SAMS™ now collects data from multiple systems throughout the three bridges, in an array of formats, at different sample rates, collating into a single user interface. The bridge managers and their consultants can view results in real-time and compare results for correlation.
Comprehensive monitoring of three bridges using several data acquisition system forms, all displaying their data for combined analysis in a singe user interface.
