Case Study: Olympia Odos achieves predictive maintenance, improved safety and lower tunnel maintenance costs with Ex Machina’s Smart Tunnel IoT platform

Smart tunnel monitoring and predictive maintenance solution for Olympia Odos

Olympia Odos, operator of the strategic 201.5 km Greek motorway, needed a more efficient way to monitor tunnel equipment and move from heavy, reactive maintenance to predictive maintenance. The company had envisioned a wireless IoT solution with cloud-based big data and machine learning; Ex Machina was engaged to turn that vision into a pilot “Smart Tunnel” system using its IoT platform and a custom gateway.

Ex Machina designed and deployed the Smart Tunnel solution—including a bespoke IoT gateway, a unique network topology and a sensor suite covering jet-fan vibration, pumps and generators, batteries/UPS and transformer conditions—and coordinated sensor installation and connectivity. Data are fed into Ex Machina’s IoT platform for real-time analysis and ML, already producing actionable insights, delivered on schedule and slated for roll‑out to all tunnels; the system enables predictive maintenance, better planning, longer equipment life, improved safety and service levels, and expected maintenance cost savings.
