SOCOTEC UK’s Monitoring team were approached to provide a temporary/rental system to monitor the railway assets adjacent to the temporary works on a railway bridge, located on River Way, Harlow, Essex. The client, Essex Highways, and Network Rail required assurance that any structural movements were in-line with predicted ground movements and that any significant movement trends could be identified at an early stage.
SOCOTEC UK’s Monitoring team proposed a monitoring system that included 75m of track tilts installed at 3m c/c spacing on each line, critical rail thermometers, both tilt and vibration monitoring on the bridge piers, and tilt monitoring on the surrounding OHLE supports. SOCOTEC’s scope also included baseline and close-out track geometry surveys, with additional surveys as required if any significant movement had been detected by the automated system. This provided further assurance to the client and Network Rail that all movements were being accurately reported.
The installation works and initial track geometry survey were completed over a single possession lasting 5.5 hours. The data was hosted online, giving the client and Network Rail live access to the data and direct email alerts if any trigger values were exceeded throughout the duration of works.
SOCOTEC UK’s temporary monitoring system provided assurance to the client and Network Rail that any structural movements were in-line with predicted ground movements and that any significant movement trends could be identified at an early stage. This allowed for quick response times and corrective action if needed, minimising potential downtime or disruptions to train services.
SOCOTEC UK’s monitoring system provided effective and reliable monitoring of railway assets adjacent to a temporary worksite. The automated system allowed for a quick and accurate reporting of any significant movement trends, providing assurance to the client and Network Rail that their assets were being monitored and protected.
