SIGTUN is a Geographical Information System (GIS) that shows the field monitoring of any infrastructure by using digitalised cartography (UTM coordinates) and the location of every single instrumentation device. SIGTUN collects manual and automatic readings from various geotechnical and structural instrumentation devices previously installed in the field.
Applus+ developed the monitoring platform in the early 2000s to manage and monitor field data obtained in infrastructure projects, assess risks, and make timely decisions.
It allows the display of information by kind of device or sensor (i.e., inclinometers, prisms, extensometers, etc.), or for an area where these sensors have been previously installed; these sensors are identified by a unique ID, shown in the GIS.
The platform is multiuser so that the user can display different information from different computers and licenses. SIGTUN shows the evolution of different measurements taken by every sensor updated on time.
It provides three alarm levels (notification, prewarning, and warning). When a reading exceeds one of these levels:
Applus+ experts have used SIGTUN in multiple infrastructure projects worldwide, including Spain, KSA, Peru, Canada, Oman, Chile, Panama, and Portugal.
The platform is addressed to infrastructure projects to allow receiving warnings if any parameter is out of a previously established security range. It receives data from the field coming from the installed devices for further analysis to make decisions about the potential behaviour of the structure.
It is focused on minimising the risk of showing on time any structural movement or settlement in the field, both during construction or during the in-service phase of the infrastructure.
