GSS monitoring solutions are the ideal answer to the monitoring requirements of all types of civil engineering projects: dams, pipelines, canals, railways, highways, ports, airports, tunnels, bridges and buildings, among others.

In order to avoid disasters, very strict safety and maintenance standards are now required by governments, not only in construction phases, but also throughout the life-cycle of civil infrastructures. Our monitoring solutions address these needs and further reduce maintenance and operational costs.


LIM: Linear Infrastructure Monitoring

Linear infrastructures pose a great challenge to wireless monitoring systems. The duration of most projects and lack of redundancy over a certain area require robust monitoring solutions that don’t rely on a single, critical path. Specific monitoring systems need to cover the entire infrastructure without critical points, specifically along railways, highways, pipelines, embankments, tunnels, and bridges. We provides just this type of linear monitoring by means of its long-range radio, which ensures direct coverage of all points throughout the infrastructure without repeaters.

SHM: Structural Health Monitoring

Structural health monitoring is emerging as a necessary tool for helping engineers improve the safety and maintainability of critical structures. SHM concentrates more and more on designing intelligent infrastructures. This means having smart, real-time control of the structure to control multiple parameters, such as: vibration, inclination, differential settlement, etc. The goal is to implement real-time data for health assessment in order to prevent collapses or other structural damage. GSS solutions combine many different sensing applications that provide complete solutions from beginning to end.

Geotechnical monitoring

Geotechnical monitoring is essential for the successful completion of most civil engineering projects, both in the construction phase as well as during operational life-cycle performance. Geotechnical monitoring is the first and most critical step in projects such as slopes, excavations near sensitive structures, land reclamation sites, retaining walls, embankments, foundations, and many others. GSS solutions deliver real-time site information to our customers in order to facilitate decision-making, and improve overall project performance in terms of both safety and productivity.


Dam monitoring is especially critical, because it encompasses a dam’s various structural parameters (strain, load, vibration, cracks and tilt) as well as those of the surrounding areas (water pressure, flow, turbidity, soil movement and settlement).  What is more, dams are often located in harsh and remote environments, which require the most flexible monitoring systems in order to adapt to changing conditions. GSS solutions meet these requirements while always keeping in mind the need for user-friendly installations and remote real-time access.


24/7 assessment of infrastructure health status to ensure safety and minimize costs.


Our client was awarded a contract to build a tunnel that would connect Hong Kong to China. For tunnel lining, the client planned to use steel fiber frames to reinforce concrete segments instead of the conventional rebar frames, which would significantly reduce costs. They developed a numerical model to assess the segment structural behavior, and were looking for a solution to obtain actual data for comparison. The comparison between the numerical and experimental results would be used to assess the effectiveness of the adopted numerical model in predicting the behavior of segmental lining under a thrust simulating the effect of the tunnel boring machine (TBM) during excavation. GSS was engaged to develop the instrumentation solution to provide strain results for concrete segments cast using both conventional rebar and steel fiber frames.

  • Limited Access: The data logging must be completely self-contained within each segment and allow wireless transmission of the data
  • Low Power Consumption: Must function for 3 months minimum, and plan to collect readings for up to 16 months. Vibrating wire strain gauges embedded in pre-cast concrete lining are not suitable
  • No Trailing Wires: The solution must function completely encased in concrete. External wires can be easily damaged and would also interfere with the vacuum pads used during erection
  • Hostile Environment: The concrete curing temperature was expected to reach 70⁰C.
  • Limit Internal Cables: The number and size of cables to be limited due to concerns the cables could affect the structural behavior of the segments.


GSS identified strain gauges specially designed to be embedded in concrete. As there is no solution in market, GSS designed and built devices specifically to meet the project requirements. In addition to providing accurate strain readings, the following challenges needed to be addressed when developing the solution: Limited Access – Self-contained battery powered DLM with PC application for wireless management Lower Power Consuption – 2 x “C Cell” batteries in the DLM powered all 7 SGMs and 21 strain gauges No Trailing Wires – All SGMs and cables were embedded in concrete Hostile Environment – All embedded components used were rated to operate between -10⁰ and +85⁰C Limited Internal Cables – RJ11 cables with protective cover used to daisy chain SGMS to provide redundancy and reduce cable requirements. The project completed successfully and the client was happy with the results, and are in the process of developing a whitepaper to share their success with the industry. The ability to measure actual strain on concrete is important to the civil engineering industry and in particular tunneling. It can have safety and commercial benefits. Our client saved US$ millions in reduced steel rebar requirements.


GSS provides low-power wireless mesh solutions for several types of natural hazards and environments. Our low power, wireless mesh networking capabilities provide reliable monitoring of many processes in endangered areas –places where precision, fast response times and reliability are needed for ensuring the safety of human settlements and infrastructures.


Subsidence and Collapse

Several regions around the world are affected by subsidence, which can produce fatal consequences in buildings as well as large-scale damage to infrastructure. The monitoring of buildings, slopes or infrastructures is crucial for keeping track of subsidence activity and assessing hazards. And while implementing a monitoring system to cover a large area is typically difficult and costly. GSS offers long-range wireless monitoring solutions that are the ideal tools for exactly these kinds of situations.


Earthquakes are one of the most dangerous and destructive natural hazards, and monitoring their of direct consequences is of great interest worldwide. In many seismic areas, it is compulsory for buildings, to be monitored for vibrations as well as the occurrence and evolution of cracks. GSS offers wireless, low-power wireless mesh solutions for monitoring buildings and their surroundings.


Floods cause substantial economic losses and casualties every year around the world. One of the biggest problems lies in obtaining information on how floods spread and evolve in relation to potentially affected catchments. Monitoring flow depth, water discharge and other parameters is a valuable tool for prevention and protection against floods. The long-range communication capabilities of GSSs’s products are the perfect solution for stations stretched out along rivers or stations spread further inland across catchments. Our low-power consumption technology allows for years of unattended precise monitoring.


Monitoring volcanic activity and its associated processes (such as gas emissions or the occurrence of lahars, among others) is crucial to early warning systems. Volcanic areas can be dangerous, so it is often mandatory that monitoring networks be easily and quickly deployed. GSS offers versatile and flexible solutions that are based on two key factors: our devices are low-power, thus requiring almost no maintenance; and they employ long-range wireless communications, which is highly important for dispersing sensors over large areas.

Debris Flow Movement – Slope Integrity

Landslides, debris flows, rock falls and avalanches are some examples of hazardous processes that endanger populations and infrastructures around the world. Monitoring systems are currently being used more and more to increase knowledge about these processes. And thanks to their warning and alarm systems, they protect people. They need for high reliability and accuracy in monitoring mass movements makes it a challenging work. GSS’s low-power, long-range wireless mesh network  meets this challenge and provides the perfect solution for monitoring in these environments

Blast Monitoring

Blast operations require highly reliable data capture and robust reporting capabilities. Our remote wireless mesh sensor network  systems ensures we are able to offer the highest level of data available.

Open Pit Mines and Underground Mines

Long-term mine planning is often particularly challenging. To ensure safety and productivity, geologists and engineers need to rely on accurate and timely data from wells and surface piezometers as well as other underground instruments.

In order to monitor so many data points in the mine teams must travel regularly to take manual readings. This is an intensive and difficult process, as many instruments are remotely located. GSS wireless networks reduce this time requirement and improve the efficiency of data-collection as well as real-time monitoring.

Our wireless network provides open-pit mines with the means to automatically collect slope wall data for storage, analysis and early warning provisions. The movement of open cast mine walls poses a major safety issue that puts personnel and expensive equipment at risk. Manual data collection can be dangerous, and cabling can be prohibitive if even an option at all. This creates the need for a low-power and low-range wireless solution.

Monitoring Key Infrastructures

Mining operations require a set of complex assets, many of which are mobile or in remote and hard-to-reach locations. Furthermore, it can be a considerable challenge to monitor the health and performance of equipment.

For reasons of production and concerns for safety and the environment the integrity of crucial installations must be maintained. Such installations include: tailings ponds, waste piles, conveyor belts and other critical mining infrastructures and assets.

Asset data can be used in maintenance programs to mitigate risks and ensure that critical equipment operates as expected.

GSS’s wireless solutions contribute significantly to implementing a proactive and preventive maintenance policy.

Conveyor Monitoring

Utilizing our best in class 3D remote wireless mesh tilt, vibration and orientation sensor technology, operators have the ability to predict when conveyors may fail or need servicing. This drastically reduces conveyor downtime, improving efficiency and overall ROI for the operator.

GSS offers complete solutions for geophysical exploration and the monitoring of industrial processes. Enhanced production, optimal safety and maintenance cycles provide the correct tools for informing the right decisions.


Digital Oilfields and Production

Operations on digital oilfields profit most when costs are low and are driven by the need to maximize recovery with predictive maintenance and enhanced production. Oil production requires extensive monitoring along flow lines, which in turn need reliable control for assessing integrity. GSS solutions provide real time monitoring with alarm levels set for all stages of production, thus reducing risk and uncertainty while delivering optimized maintenance management. The ultimate goal is to improve safety and maximize production efficiency.

Reservoir Monitoring

Reservoir monitoring as well as controlling gas and CO2 reservoirs are important for ensuring the safety of input and output operations. Cap rock integrity and fluid movements should be carefully controlled in order to verify reservoir stability and to guarantee that activities are at optimal performance. GSS integrated solutions include micro seismic remote monitoring and control. Combining these two factors has proven to be essential in providing the right tools for monitoring reservoir behavior and fluid migration through the subsurface.

Exploration and Passive Seismicity

European regulations stress the need to monitor oil and gas activities especially in populated areas. Exploration trends have begun to shift from active methods to passive methods, with a focus on natural seismicity as a cost-effective source of data monitoring and control, while at the same time having less impact on the environment. Our monitoring systems characterize this natural and passive seismicity with precision and provide valuable information on terrain characteristics. The Our solution includes precise wireless broadband instrumentation as well as data processing and output.

Transport Pipeline

One key to optimizing oil and gas outcomes is the ability to control the downstream operations of storage and distribution. Having complete oversight over all stages of transport is essential for maximizing efficiency. Ensuring transport security involves monitoring not only pipelines but also the surrounding areas and the stability of the terrain. Our solutions address these needs by facilitating the means to monitor pipeline deformation and stress, joint leakage, ground settlement, groundwater pressures, and seismic events.
