STRUCTURAL HEALTH MONITORING
STRUCTURAL HEALTH MONITORING
NHAZCA at the forefront of structural health monitoring
Structural Health Monitoring (SHM) is NHAZCA’s response to the challenges facing the world’s infrastructure today. The average age of infrastructure, climate change, and increasing capacity demands, require continuous monitoring to ensure safety – and we can do this through cutting-edge technologies that allow us to accurately monitor the static and dynamic behavior of infrastructure over time.
What is Structural Health Monitoring (SHM)?
NHAZCA’s Structural Health Monitoring (SHM) is an approach that allows us to assess and manage the health of infrastructure over time. We do this by using a variety of damage detection techniques to monitor and analyze the conditions of bridges, buildings, dams, and other relevant structures.
Our vision of structural monitoring helps us detect early signs of deterioration or damage, while providing data to organize predictive maintenance and make more strategic decisions.
Our goal is to ensure the safety of infrastructure through real-time monitoring to identify potential threats to structural stability and prevent major damage or even disaster.
Cos'è lo Structural Health Monitoring (SHM)?
Lo Structural Health Monitoring (SHM) di NHAZCA è un approccio che ci permette di valutare e gestire la salute delle infrastrutture nel tempo. Per farlo, utilizziamo una serie di tecniche di rilevamento spostamenti o cambiamenti per monitorare e analizzare le condizioni di ponti, edifici, dighe e altre strutture rilevanti
La nostra visione del monitoraggio strutturale ci aiuta a rilevare i segnali precoci di degrado o danneggiamento, dandoci allo stesso tempo dei dati per organizzare la manutenzione predittiva e prendere decisioni più strategiche.
Il nostro obiettivo è salvaguardare la sicurezza delle infrastrutture con il monitoraggio per identificare ogni potenziale minaccia alla stabilità strutturale, per prevenire danni maggiori o addirittura disastri.
NHAZCA's innovative approach
With this approach, we can guarantee you predictive maintenance, moving from a reactive to a proactive model of securing assets by anticipating problems before they occur.
NHAZCA's technologies for SHM
NHAZCA’s Structural Health Monitoring is intelligent monitoring: it relies on the use of innovative, consistently advanced and proven technologies for the historical characterization of large-scale infrastructure networks, performing non-invasive and cost-effective analyses.
Interferometria SAR e RAR
Terrestrial and satellite SAR interferometry uses advanced sensors to analyze minimal ground variations to provide a complete view of surface deformations on a large scale. This type of monitoring, made possible by data collected from satellite or ground-based platforms, is critical for land use planning, slope stability assessment, subsidence monitoring, and large structures such as dams, buildings, and various infrastructure.

GNSS Systems and UAV Sensors
Satellite navigation receivers are used for a variety of applications including positioning, navigation and surveillance.
Monitoring with GNSS systems makes it possible to determine the exact position of the receiver with an accuracy of the order of a few millimeters, thus providing information on the deformation of local movements based on the variation of the plano-altimetric position of the monitoring point, i.e. along the north-south, east-west and vertical directions with respect to an absolute reference system.
In the field of natural hazards and large infrastructure projects, UAV systems can be extremely useful for various applications
- Optical inspections to monitor remote or hazardous areas and infrastructure;
- 3D UAV photogrammetry to reconstruct high-resolution 3D models, DEM (Digital Elevation Model), contour maps, and to detect volume changes by comparing 3D models taken at different times;
- IR thermography, useful for a variety of purposes such as characterizing fracture zones in rock faces or infrastructure.
NHAZCA's technologies for SHM
SAR and RAR Interferometry
SAR interferometry is one of the most advanced technologies for structural monitoring. With this technique, we can analyze structural variations based on both terrestrial (TInSAR) and satellite (A-DInSAR) configurations.
Terrestrial and satellite SAR interferometry uses advanced sensors to analyze minimal ground variations to provide a complete view of surface deformations on a large scale. This type of monitoring, made possible by data collected from satellite or ground-based platforms, is critical for land use planning, slope stability assessment, subsidence monitoring, and large structures such as dams, buildings, and various infrastructure.
Terrestrial RAR Interferometry (TInRAR), using SAR configuration and special algorithms, allows the acquisition of three-dimensional maps of displacements, implementing advanced geotechnical monitoring. This technology, combined with the ability to dynamically and statically monitor structures, is a valuable ally in gaining a complete picture of the structural health of infrastructures
PhotoMonitoring™ and Laser Scanning
PhotoMonitoring™ is NHAZCA’s innovation that revolutionizes the traditional approach to monitoring by relying on the vast and easily accessible photographic heritage through the advancement of imaging technology. With PhotoMonitoring™, we use advanced digital image correlation algorithms to analyze displacements and changes with unprecedented accuracy.
PhotoMonitoring™ and laser scanning are advanced structural diagnostic tools that are essential for ensuring the safety and integrity of infrastructure at every stage of its operational life. In fact, terrestrial laser scanning maximizes the effect of photoMonitoring™ by allowing us to quickly acquire detailed data on the three-dimensional geometry of structures and terrain.
This technology is very useful for vibration analysis and structural condition assessment of buildings and infrastructure, working on a very large database to improve the quality of your decisions.
GNSS Systems and UAV Sensors
This system provides a global positioning service that allows a small receiver to determine the geographic coordinates and thus the position of any point on the Earth’s surface.
Satellite navigation receivers are used for a variety of applications including positioning, navigation and surveillance.
Monitoring with GNSS systems makes it possible to determine the exact position of the receiver with an accuracy of the order of a few millimeters, thus providing information on the deformation of local movements based on the variation of the plano-altimetric position of the monitoring point, i.e. along the north-south, east-west and vertical directions with respect to an absolute reference system.
