JFTS delivers structural health monitoring project on three Normandy bridges

Overview

James Fisher Testing Services (JFTS), in partnership with the civil engineering consultants COWI, has designed and installed integrated structural health monitoring (SHM) solutions on three bridges in Normandy; The Pont de Normandie, Pont Tancarville and Viaduc du Grand Canal.

The project started in late 2018, with the installation and commissioning completed in mid-2019. The ongoing monitoring and maintenance support is set to continue through to until at least 2022.

Challenge

The scope of the project was to review and update the existing systems on all three bridges due to poor performance. The customer had specific concerns regarding deck fatigue and cable stay failure.

 In contrast to their previous solution the customer wanted an integrated platform that combined their data sources into clear, actionable insight in order to streamline processes and improve efficiency.

Solution

A key element of the updated solution was JFTS' Smart Asset Management System (SAMS™), which produces intelligent insight through ‘data fusion’ in contrast with unintegrated data from multiple sources. The automated reporting feature of SAMS™ delivers the client monthly updates with a concise summary, empowering users to make quick, data-based decisions on the structural health of their assets. Key parameter displays have been developed alongside real-time email alerts for pre-configured events.

In total, there were about 400 sensors installed that monitor a range of parameters: strain, acceleration, displacement, environment and acoustic emissions. The system also integrated with third-party inputs and systems, amalgamating them into the SAMS™ platform, creating a single centralised point to compile and review multiple sources of data.
