New project in Lisbon to monitor walls and slopes

The equipment installed, the technicians explain, allows alerts to be issued "in the event of movements that are critical, allowing a rapid response if anomalous values are found".

The pilot project - with nine sensors on a wall and two on a slope at the Instituto Superior de Agronomia - is part of the Lisbon Municipal Civil Protection Service's risk monitoring and prevention system , in partnership with the companies Geocompass and Senceive.

The system works autonomously, without the need for regular local measurements, and the data is collected and sent via GSM (global system for mobile communications) in real time for later analysis.

This equipment, they add, has been installed "in several European countries, especially on railways, bridges, monuments and buildings with structural pathologies".
