Nerve-Sensors along the gas pipeline
The section of new gas pipeline was equipped with 3DSensors and EpsilonRebars enabling geometrically continuous measurements of strain, displacement and temperature during a leak proof test and during the first months of gas pipeline exploitation. Obtained data allowed for identification of local disturbances relevant to changes in the pipeline geometry. The 3DSensors provided the possibility to identify the places where excessive deformations occurred due to e.g. local subsidence or landslides.

Naval Base of Gdynia
Along the rebuilt western dyke, performed work can generate high vibrations, which will have a negative impact on the technical condition of nearby structures. The designed and implemented automated vibration monitoring system will control these structures in real time 24/7, and in case of any irregularities will alert about it. Thanks to this, it will be possible to react immediately.

Warszawa Zachodnia train station
The scale of the investment and the responsibility of rebuilding the Warszawa Zachodnia train station requires effective protection and continuous vibration monitoring of the existing infrastructures generated by the construction work. In the next few years, monitoring will cover a total of 20 buildings, on which we will install several hundred measurement sensors. Implementation of such a large and extremely responsible system performing automated measurements in a 24/7, was possible thanks to the knowledge and many years of experience of SHM System engineers.

Slurry walls within a research project
Once again we had the pleasure to participate in a research project in which our unique sensors had a key role in the analysis of new technical solutions. The Soley company is currently developing the technology of fibrogrouted concrete walls and we are happy to continue our fruitful collaboration. After experience from two previous projects, where we performed automatic measurements with vibrating wire sensors, automatic inclinometric measurements using the Inclify system and geometrically continuous DFOS measurements, we are looking forward for a new challenge.

Inclinometric measurements of high embankments
The highest road embankments in Poland, reaching up to 30 meters, monitored by SHM System engineers! Such large embankments were constructed as part of the S-7 expressway between Warsaw and Krakow. The monitoring system controlling embankment settlement included both vertical and horizontal inclinometer displacement measurements, located in the area of three measurement plots.

SHM PROFILER – from the laboratory to the construction site
SHM Profiler is an innovative solution for automatic monitoring of vertical displacement, developed by SHM System engineers. The hydraulic measurement system, dedicated for applications in construcion and geotechnics, is characterized by a wide measuring range, easy installation and low costs. What is most important, it is equipped with our original system of temperature compensation, thanks to which its influence on sensor readings will be automatically compensated.

3DSensor – Ground displacement
The aim of this project was to determine the potential slip plane which occurred during pullout of concrete footing. For this purpose, 3DSensors (DFOS displacement sensors) were installed around the structure in two planes and vertical displacements were measured. Thanks to the cutting-edge technology of 3DSensors, an advanced analysis of the interaction between the footing and the surrounding ground was possible without any distortions and reinforcing effect in the ground.

Smart footbridge in Nowy Sącz equipped with DFOS sensors
EpsilonRebars in the form of composite rods being simultaneously the structural reinforcement for the concrete deck, were placed along the entire footbridge span of nearly 80 m. Thanks to the application of distributed optical fibre sensing technique it was possible to perform measurements of strains, cracks, displacements (deflections) and temperatures during the hydration of early-age concrete (thermal-shrinkage strains) as well as during the load tests.

A1 – Smart Highway equipped with integrated self-diagnostic system
The project involves a 100 m long section of the highway in Poland, which was reinforced only with composite bars, including EpsilonRebars from Nerve-Sensors family. The entire experimental section was concreting without any dilatations, what is a really pioneering approach in road engineering. Our DFOS-based monitoring system provided essential information on strain profiles and crack morphology, being at the same time the structural reinforcement.

Skyliner Skyscraper in Warsaw
One of the tallest skyscrapers in Poland, 195-meter high is being built in Warsaw. The scale of the investment and related engineering challenges have led to the start of cooperation between the General Contractor - Warbud S.A. and structural health monitorng experts - SHM System. The result of our work is a system providing the safety and quality of performed work by automatic measurements of selected engineering values and alerting system.

Multi-purpose indoor ARENA in Gliwice
The ARENA in Gliwice is one of the most modern sports and entertainment halls in Poland, unique because of the structural and geometric solutions applied, but also in terms of the fact that it is equipped with an advanced automatic monitoring system. Dozens of sensors carry out measurements of selected physical quantities (static as well as dynamic), relevant to the assessment of its operation, especially in the context of snow and temperature loads.

Office building “Brama Miasta” in Łódź
This investment is the second largest system for vibration monitoring in Poland, after the HighFive investment in Krakow. During our fruitful collaboration with SKANSKA S.A. we developed and successfully implemented an integrated system that allows real-time 24/7 control of vibrations transmitted to the surrounded buildings. All sources of vibration are recorded, not only generated by construction work, but also those made by telecommunication.
