Innovation is at the heart of Systra Italy, and our latest breakthrough, ATAS (Advanced Tunnelling Assistance Systems), is set to redefine how we approach underground excavation.
What is ATAS?
ATAS is a platform that integrates real-time data analysis, machine learning, and advanced algorithms to optimize tunnelling operations. Much like ADAS (Advanced Driver Assistance Systems) in the automotive industry, ATAS monitors ongoing excavation, identifies risks, and assists in making fast, informed decisions.
HOW IT WORKS:
ATAS orchestrates a “symphony” of data, continuously interpreting information from TBM sensors to refine our understanding of the geological landscape. It employs multiple advanced methodologies:
Soil characterization
- Thrust analysis determines the friction coefficient between soil and shield.
- Torque analysis estimates the soil’s equivalent friction angle.
- Belt scale measurements detect soil density variations.
- Pressure discharge analysis evaluates soil permeability.
- TBM data clustering automatically classifies excavation areas.
Settlement predictions
- Analytical models provide real-time estimations.
- FEM simulations compute settlements under different conditions.
- Machine learning (LSTM networks) predict settlements with progressive retraining.
- Final settlement forecasts continuously refine calculations using monitoring data.
By analysing these parameters, ATAS transforms the tunnelling process into an intelligent, adaptive cycle. For every excavated ring, TBM parameters are analysed, soil characterization is performed, and settlements are calculated. If settlement thresholds are exceeded, ATAS suggests new excavation parameters for the next ring, ensuring a proactive approach to risk management.
Real-World Impact: Proven Success
ATAS has already proven its value in real-world projects. One of its first successful applications was the railway underpass excavation project, where complex and variable geology posed a significant challenge. ATAS provided critical insights that enabled the tunnelling team to navigate uncertainties, optimize operations, and ensure excavation safety and efficiency.
Following this success, ATAS is now being implemented in other railway and transportation projects worldwide. Its ability to adapt to changing geology, sand, clay, water tables, and historical building interactions makes it a revolutionary tool in underground engineering.
Award-Winning Innovation
We are honoured that ATAS was awarded Innovation of the Year at the ITA Awards 2024. This recognition highlights Systra Italy’s commitment to pushing the boundaries of tunnelling technology. ATAS is not just about optimizing excavation—it is about transforming how we build tunnels by making design a continuously evolving, AI-driven process.
Looking Ahead: The Future of Tunneling
By leveraging artificial intelligence, real-time data analysis, and advanced engineering techniques, ATAS is setting a new standard for the future of underground construction. It enables tunnelling crews to make faster, smarter, and safer decisions, reducing risks and maximizing sustainability.
At Systra Italy, we believe that engineering innovation and AI-driven adaptability will shape the tunnels of tomorrow. With ATAS, the industry is moving toward a future where tunnelling is not just planned but intelligently guided every step of the way.
