What happens when underground construction practice doesn’t follow design theory? How can engineers find out what is actually happening with accuracy to reduce risk? The principles of structural monitoring have been known for many years but technical developments in instruments to test ground conditions in situ have increased reliability and reduced cost to such an extent that the wealth of information available has required new thinking in data handling, analysis and presentation. Maurice Jones checks with some leading participants on how data is now collected handled and used, plus how improvements might come about
