Often parts of the structures (e.g. bridges, tunnels, dams etc.) are relatively inaccessible and hence any sensor systems need to be easy to install, suitably rugged and have a long service life. The monitoring employed needs to be able to identify problems often hidden within structures before they become serious. Near real-time monitoring of movements between components of the structure allows assessments of the overall performance of the structure and to predict its durability and remaining life.
Tenet were tasked to undertake development work to provide the “Proof of Concept” for a sensing system to detect sub-millimeter movements in components of a large civil structure. Many commercial systems only sense in a single dimension, however the customer required simultaneous real-time 3-Dimensional structural monitoring, which precluded the use of many existing commercial measurement systems.
