To detect stresses and deformations in large structures before they cause damage and deaths, the European Space Agency is working with the UK's University of Nottingham to monitor the movements as they happen using satellite navigation sensors. The team uses highly sensitive satnav receivers that transmit real-time data to detect movements as fine as 1 cm combined with historical Earth observation satellite data. By placing sensors at key locations on the Forth Road Bridge in Scotland, they detected stressed structural members and unexpected deformations

The global market for the installation of GeoSHM on existing and currently planned long-span bridges is worth in excess of $1.5 billion. The UK market alone is estimated to be worth in excess of £200 million and growing. China is expected to be the largest market. While GeoSHM is designed mainly for monitoring bridges with a main span greater than 400 m, it also has potential for shorter bridges, such as Hammersmith Bridge and the Millennium Bridge in the UK. “Eventually, GeoSHM could be deployed for monitoring offshore wind turbines, masts, towers, dams, viaducts and high-rise buildings, for example,” said Xiaolin Meng, GeoSHM team leader.

    Your link to the I5 collapse links to the I35 collapse. It should link to this [wikipedia.org].
