fibrisTerre is delighted to be a Sponsor of the 11 th International Course on Geotechnical and Structural Monitoring in Poppi starting June 23.
The lessons will cover the design of a monitoring program, monitoring sensors and system installation, data acquisition and management, and the process of translating data into actionable information.
The event also includes group work on various topics (e.g., dams, linear infrastructures, natural hazards) and a visit to the experimental and permanent monitoring site for the Poggio Baldi landslide, one of the largest rock and debris landslides in the Emilia-Romagna Apennines.
This bridge has it all! An infrastructure asset owner’s dream, all packed into 45 m and 4.5 m wide, managed by scientists.
It is the brainchild of the Infrastructure Data Analysis with Artificial Intelligence (IDA-KI) research project, which aims to develop methods for the automated analysis and evaluation of monitoring data.
The bridge has a rail-guided load vehicle. Hydraulic presses and a load traverse apply force for static load tests. Thanks to a ‘shaker’ mechanism, its dynamic structural behavior in different frequency ranges can be investigated.
Let’s talk monitoring: air temperature, relative humidity, solar radiation, and precipitation are recorded. There are strain gauges, inductive displacement transducers, an accelerator sensor, and Distributed Fiber Optic Sensing (DFOS).
About 1.5 km of sensing fibers are installed in the pre-cast elements and in situ. They record strain and temperature, providing ‘the nerves of the structure’.
The high-frequency monitoring data is incorporated into the associated BIM model.
Real-time visualization of both raw sensor readings and aggregated system status are available via a browser. Threshold-based alarms can be automatically triggered to flag anomalies or critical conditions.
The project is funded by the Federal Ministry of Digital and Transport (BMDV) as part of the mFUND research initiative.

fibrisTerre collaborated with Network Rail and Senceive in the U.K. to provide event detection and location for a robust, comprehensive automated rockfall warning solution.
fibrisTerre’s distributed fiber optic sensing system, integrated into a catch fence, provides rapid detection and location of rockfall events, and can monitor over many kilometers. Initial tests were completed in Switzerland.
The benefits of detecting and locating rockfall remotely, in real time, allow for rapid mitigation. For example, knowing the exact location of the event, response crews can be dispatched precisely where they are needed, ensuring a swift and efficient response.
The system is shortlisted in the Award for Equipment Innovation category.
Initial lessons learned, key challenges, and how these were overcome on a first-of-a-kind project to monitor both piles and connecting rafts over at least two years:
“If you cannot measure, you cannot improve. Learning from real-time monitoring of piled raft foundations in a deep basement in London”
will be presented during Ground Engineering Magazine’s Basements and Underground Structures event on October 3 by:
*Dr. Dimitrios Selemetas, Technical Director, AKT II,
*Will Argent Geotechnical Design Engineer, AKT II,
*Adrian Bywaters Operations Director-Engineering, Mace and
*Dr. Nicky de Battista, Director, Epsimon Ltd.
The Conference is colocated with Smart Geotechnics.

Salerno, Italy 4-6 September, is the place to be for Smart Monitoring, Assessment and Rehabilitation of civil structure, co-organised by the Structural Engineering Laboratory of Empa, the Swiss Federal Laboratories for Materials Science and Technology, and the Department of Civil Engineering of the University of Salerno, Italy.
MS09/1 and 2 (sessions 3G and 4G)are Mini Symposia on Advances in Fiber Optical Sensing Solutions for Infrastructure, Geotechnics and Earth Sciences.
Covering applications in soil stabilisation, landslides, water pipelines, boreholes, subsidence, bridges, tunnels, and rail displacement, presentations highlight the latest advances in monitoring with distributed fiber optic strain sensing.
fibrisTerre is presenting:
“Distributed Fiber Optic Smart Geosynthetics for Geotechnical Applications in Transportation”

September 5, Session 4-G MS09/2 Advances in Fiber Optical Sensing Solutions for Infrastructure, Geotechnics and Earth Sciences
“We present the latest works in the design, development, validation and industrial application of geosynthetic materials equipped with integrated fiber-optic sensing cables for distributed strain and temperature measurements. The integration of fiber-optic sensors into geotextiles and geogrids – as they are commonly used in geotechnical construction for soil stability improvement, erosion protection, draining, filtering and other tasks – provides a feasible integration method for the sensors into the structure under monitoring. The one-dimensional characteristic of a longitudinal fiber-optic strain sensor is thereby transformed into a two-dimensional shape sensing plane, providing distributed, uninterrupted information on deformation, sinkholes, slope movements, settlements and many more geotechnical indications on structural failure.”
Full papers will be collected in the
Conference Proceedings, which are going to be published by Elsevier in a dedicated issue of Procedia Structural Integrity (Online ISSN: 2452 – 3216), an open access journal publishing under a CC – BY – NC – ND license full papers presented in scientific conferences.
We look forward to meeting you in Salerno!
‘Challenges of Geotechnical Engineering to meet current and emerging society needs’ is the theme of the upcoming conference in Lisbon, Portugal, August 26-30th
We look forward to welcoming you on stand 76 and would love to hear about your project and how you plan to monitor structural deformation, strain or displacement – during construction and in operation.
Distributed fiber optic sensing offers reliable, precise and cost-effective monitoring offering:Want to know more or share a fiber optic monitoring experience experience? Visit fibrisTerre on stand 76!

Research is in fibrisTerre’s DNA, so it was exciting for Nils Nöther to meet fellow scientists from the University of Clausthal and Freiberg University of Mining and Technology for the inaugural meeting of the MOVIE project team.
MOVIE is part of the Georesearch for Sustainability (GEO:N) program funded by the German Federal Ministry of Education and Research (hashtag#BMBF)
A digital twin, in the form of a virtual laboratory, will be developed based on: a real underground laboratory provided by “Reiche Zeche” research and training mine with monitoring data from fibrisTerre Systems’s distributed fiber optic sensing
The virtual laboratory will investigate and support sustainable mining practices and promote efficient and responsible management of underground systems.

fibrisTerre is honored to be part of the MULTICLIMACT project.
The project builds on the experience of 23 partners from 10 European countries, leveraging a vast amount of knowledge and expertise to develop a framework and a tool for supporting public stakeholders and citizens to assess the resilience of the built environment.
fibrisTerre’s contribution is based on continuous, real-time monitoring using distributed fiber optic sensing to provide early warning of potential failures in dikes and linear infrastructure assets.
‘Innovative risk assessment and prediction technologies will be tested at four pilot sites in Camerino (Italy), Barcelona (Spain), Riga (Latvia) and Leischendam-Voorburg and Roermond (The Netherlands). Four pilot sites with diverse climatic conditions are therefore susceptible to different types of climate-related environmental disasters.’
The International Society for Soil Mechanics and Geotechnical Engineering (ISSMGE) is ‘the pre-eminent professional body representing the interests and activities of Engineers, Academics and Contractors all over the world that actively participate in geotechnical engineering.’
Founded in 1936, the ISSMGE provides a global focus for professional leadership to some 90 Member Societies and around 20,000 individual members.
The ISSMGE provides a valuable online library which is freely available.
Here is the ISSMGE video and yes, fibrisTerre loves geotechnical engineering:
