The Kingston Bridge is one of Europe's busiest river crossings, carrying 150,000 vehicles a day high over the Clyde in the centre of Glasgow. The bridge is a key link in the West of Scotland's motorway system and it also plays a vital role in Scotland's economic life.
The Kingston Bridge was hailed as a remarkable piece of engineering when it was built almost 30 years ago. That year, daily vehicle crossings totalled 31,000. Major defects were discovered in the bridge in 1990. The 163-year-old north pier wall near the bridge's support piers was found to be bulging.These problems required intensive remedial action. This ultimately involved moving the bridge onto a new set of supports.
Over the period of 10 years and up to the current day, the Kingston Bridge has become the most closely monitored bridge in the world. The engineers have ensured that the Kingston Bridge meets the toughest safety criteria. Bridge movements and meteorological data are being continuously recorded and ground surveys are taken regularly to give an overall picture of how the bridge is behaving.
Over the years of monitoring and during the critical movement of the bridge, the equipment used for monitoring and recording the bridge movement, was the Measurement Systems range of Datascan Distributed I/O and the Orchestrator data acquisition monitoring and logging software. Due to it's distributed design and it's accurate stable measurement capability the Datascan was ideal for this particular application. Over the years of monitoring the Orchestrator software was used to record bridge movement which were kept in log files. Long term analysis of these files showed bridge movement over the duration.
