Located in close proximity to the busy 170-year-old Network Rail viaduct into Vauxhall Overground Station, ITM, now SOCOTEC Monitoring UK Ltd, worked on a consultative basis with structural engineer, WSP Parsons Brinckerhoff, to design a monitoring system to ensure that critical assets are monitored for movement in real-time during the demolition and construction phases of this exciting development.


The demolition phase of the project saw removal of the existing self-storage warehouse and office accommodation occupying the site. ITM installed a range of instrumentation including Automated Total Stations (ATS), electrolevel beams and vibration sensors to monitor the effects of demolition on the surrounding structures and rail tracks, including the viaduct arch facades, the full width of the viaduct, surrounding roads and bridges and the construction site itself. The system was assisted by temperature sensors and vibration monitors to ensure a fully comprehensive automated monitoring system across the site, as well as precise manual monitoring surveys.
During the construction phase, ITM installed additional electrolevel beams within the viaduct arches as well as inclinometers within the pile walls to closely monitor the movement of the ground and surrounding structures, from excavation through to completion.

ITM’s online monitoring software, Calyx, was chosen for data interpretation for the duration of the project, providing a user-friendly graphical interface collating all monitoring data, with ITM providing 24/7 alarm checking and response.

'Working to Network Rail’s strict monitoring requirements and in line with WSP’s geotechnical guidance, ITM’s professional approach was key to the successful monitoring of the work site'. Edward Lumley, senior project manager at Turner & Townsend
