​Basics still essential despite advances in monitoring technology

New instrumentation and monitoring technology now available has the potential to change the sector and offer better measurements and improved resolution but the sector has been warned not to ignore the basics.

Speaking at today’s GE Instrumentation and Monitoring Conference in London, Imperial College reader in ground engineering Jamie Standing made the call while reviewing the impact of emerging technology.

“Regardless of the technical sophistication that new technology offers, it is essential to understand what the results mean,” said Standing during his keynote speech. “The industry also needs to be clear about whether the results show relative movement or absolute movement.”

According to Standing, technology now available means that displacement can now be measured with ease and accuracy but that movements now expected from some projects is now very small, so understanding of background movement of existing structures is essential. Standing pointed to the thermal response of the Big Ben clock tower during construction of the Jubilee Line as an example.

Standing also called for greater consideration to be given to the presentation of data. “There is a vast amount information collected using real-time systems and the processing and analysing can be a major task and how this is managed should be considered when the system is designed.”
