Nhazca’s SGAM service: solid foundations for your projects

A smarter way to manage geotechnical risk across infrastructure networks

SGAM is NHAZCA’s solution for infrastructure asset managers who need to move from reactive maintenance to risk-based decision making. Instead of focusing only on known critical points, SGAM helps screen large transport networks, identify priority areas and support maintenance planning with a clearer picture of geotechnical risk.

This geotechnical asset management approach helps infrastructure teams move from isolated inspections to network-wide risk prioritization

For large transport corridors, geotechnical asset management means understanding hazard exposure, asset vulnerability and maintenance priorities across the whole network.

What is SGAM?

SGAM, Smart Geotechnical Asset Management, is a decision-support solution for the maintenance and management of geotechnical assets such as embankments, slopes and tunnels. It helps asset managers assess current and potential impacts from landslides, floods, subsidence and seismic vulnerability, so they can prioritize interventions where they matter most.

What is SGAM?(Smart Geotechnical Asset Management)?

SGAM (Smart Geotechnical Asset Management) is an innovation in geotechnical engineering that uses a predictive data set and analysis to help you identify and prioritize geotechnical asset management activities by applying a risk-based management strategy.

The heart of SGAM is its technology: through the use of artificial intelligence, SGAM is able to build its analyses by combining information from satellite platforms, global and regional geohazard databases, field survey data, and ground-based structural and geotechnical/geomorphological monitoring systems.

How SGAM works

SGAM combines multiple data layers into a single risk-analysis framework to support more informed maintenance decisions.
  • Satellite and Earth observation data
  • Global and regional geo-hazard databases
  • Field survey data
  • Structural, geotechnical and geomorphological monitoring systems
  • Artificial intelligence for data fusion and prioritization
  • Expert validation and consultancy

SGAM helps decision makers and asset managers prioritize maintenance activities using a risk-based, network-wide geotechnical asset management approach. 

The result is a more comprehensive view of infrastructure health, including not only where risk exists, but also how reliable the available evidence is.

Why SGAM is different from traditional geotechnical asset management

Traditional geotechnical asset management often focuses on limited areas where risk is already known. SGAM expands that approach by screening large infrastructure networks, combining multiple data sources and supporting more strategic maintenance planning across the whole asset system.

 

Network-wide visibility

Move beyond isolated critical points and gain a broader understanding of geotechnical risk across roads, railways and related assets.

Better prioritization

Use integrated, multi-source evidence to identify where intervention is most urgent and where deeper investigation is needed.

Predictive maintenance support

Anticipate emerging issues earlier and support safer, more cost-effective maintenance strategies over time.

What you get

SGAM turns complex geotechnical data into outputs that support clearer maintenance decisions and follow-up actions.
  • Satellite and Earth observation data
  • Reliability rating of results
  • Automatic identification of areas subject to differential movements
  • Expert interpretation and technical reporting
  • Preliminary technical and economic proposals for critical issues
  • Site-specific in-depth analysis for the most critical areas

Who SGAM is for

Geotechnical risk assessment for water transmission infrastructure

Water transmission infrastructure

Assess the vulnerability of distributed assets and support maintenance planning with a clearer understanding of ground movement and related hazards.

Geotechnical asset management for road and rail corridors on unstable slopes

Transportation companies

Identify landslide-prone areas, ground deformation and seismic vulnerability along roads and railways to improve safety and reduce service disruption.

Civil infrastructure monitoring for electricity transmission corridors

Electricity transmission infrastructure

Prioritize interventions and reduce the risk of outages by monitoring terrain instability and other geotechnical threats affecting network continuity.

Business benefits

SGAM helps infrastructure managers turn complex geotechnical risk into clearer priorities, more efficient maintenance planning and stronger network resilience. By combining multi-source data, AI-driven analysis and expert validation, it supports safer decisions across large transport and utility networks.

Smarter maintenance prioritization

Move from reactive interventions to a risk-based maintenance approach that helps teams identify where action is most urgent and where deeper investigation is needed.

Reduced disruption and downtime

Anticipate geotechnical issues earlier to minimize closures, avoid service interruptions and reduce the operational impact of unexpected events across critical routes and assets.

Better use of budgets and resources

Focus technical effort and maintenance spending where risk is higher, helping organizations reduce inefficiencies, avoid unnecessary interventions and support more cost-effective planning.

Stronger asset resilience

Improve the long-term safety, reliability and resilience of infrastructure networks by combining hazard screening, vulnerability analysis and data-backed decision support.

 

The differences between GAM and SGAM

Global coverage
SGAM provides comprehensive monitoring over very large areas, unlike GAM, which focuses on limited areas, exposing assets to potential security risks.
Cost optimiztion
Using advanced technologies and predictive analytics, SGAM reduces waste and improves the financial sustainability of infrastructure management.
Cutting-edge technologies
SGAM uses advanced technologies such as A-DInSAR and Photomonitoring™ for more accurate data analysis than standard GAM.
Predictive maintenance
SGAM’s predictive algorithms allow you to identify potential problems earlier, resulting in proactive maintenance strategies.

What NHAZCA's advanced SGAM service offers

Less waste, more control, more safety: SGAM is the NHAZCA innovation that makes complex information accessible and identifies your risk mitigation priorities.
Automatic classification of geographic risks
SGAM is based on an automated geotechnical hazard classification system. Combining artificial intelligence with one of our dynamic databases of geotechnical and geomorphological information, SGAM analyzes and interprets data from multiple sources to accurately identify areas at risk in real time.
Technologies such as Photomonitoring™ and A-DInSAR analyze satellite data to give you a comprehensive view of landslide and flood prevention, subsidence, and seismic risk, considering the environmental impact of geotechnical works.
Automatic classification is the answer to mitigating potential hazards and planning predictive maintenance to ensure the safety of infrastructure and people.
Analysis of structure-environment interactions
Geological risk analysis is completely redefined with SGAM.
The goal is to understand the impact of hydrogeologic hazards on the mitigated infrastructure. Our analysis evaluates the impact of multiple geohazards, such as ground motion, hydrologic changes, and seismic activity, on the stability and integrity of structures.
By mapping specific vulnerabilities, you can use the data to implement hazard mitigation strategies and increase the resilience of your infrastructure.
Integration of satellite and terrestrial data
SGAM’s true strength lies in the integration of satellite and terrestrial data, bringing together geotechnical data from the space industry, global and regional databases, and structural monitoring systems. This approach is key to harnessing the full potential of remote sensing for geotechnical applications, providing a comprehensive view of subsurface conditions.
Our model processes a large set of qualitative and quantitative data, creating a unique and dynamic database for predictive analysis that is enriched as new information is continuously added.
We combine traditional tools with innovative satellite data acquisition technologies such as PhotomonitoringTM and A-DInSAR.
