The SAIN technology uses acoustic sensors and machine learning to continuously monitor infrastructure assets like bridges, dams, and railways in a non-intrusive way. It analyzes the acoustic signatures of structures to detect changes that may indicate issues. This allows for remote, long-term monitoring without direct sensor attachment. The system provides real-time alerts, monthly health reports, and integrates with existing asset management tools. It aims to improve on current sporadic monitoring techniques by providing a comprehensive, low-maintenance monitoring solution for the many aging infrastructure assets worldwide.

The idea;
to use a solar analysis technique to probe the
internal structures of assets.

4. Increasing Rail Bridge Risk Factors
4
Ageing
infrastructure
coming under
increased
pressure
Flood damage
Wind damage
Earthquake risk
(natural and
man made
‘fracking’)
Heavier traffic
Bridge
Collisions
Increased
speed of trains
Increasing
length of trains
Increased
frequency of
trains
5. The Challenge (bridges opportunity)

UK
• 35,000 rail bridges
• 3% year on year growth of
rail traffic
• 30% of bridges >100 years
old
• 74,000 road bridges
• 3,000 dams
USA
• 614,000 road bridges
• 1 in 11 road bridges rated
structurally deficient
• 40% of rail bridges >50 years
old and near end of design
life
• 100,000 rail bridges
• 91,000 Dams
Europe
• 300,000 rail bridges
• 300 bridges at risk of
failure in Italy 2019
Worldwide
• 10 major bridge failures in
2018 alone
Asia
• High frequency of seismic
activity
