With a strong foundation in aerospace and defense applications of SHM, Acellent has expanded to civil infrastructure, providing advanced sensing solutions that can continuously assess structural integrity.

At the core of Acellent’s offering is its proprietary SMART Layer® technology. This is essentially a thin flexible sheet embedded with a network of tiny sensors and actuators (often piezoelectric transducers) that can be bonded onto structures. The SMART Layer acts as the “nervous system” of a structure, capable of sending and receiving stress waves to detect cracks, delamination, or other forms of damage in materials. Acellent pairs these sensor networks with dedicated hardware modules and software, creating a full end-to-end SHM system. The system can localize damage, estimate its severity, and even predict remaining structural life using AI algorithms on the collected data.

Key Technologies and Solutions:

• SMART Layer® Sensor Networks: Acellent’s signature product is the SMART Layer, a sensor mat that can be permanently attached to the surface of structural components (such as a concrete beam, a steel girder, or a composite aircraft panel). The layer contains an array of piezoelectric sensors and possibly fiber optics or other sensor types, all integrated in a thin film. These sensors can actively send ultrasonic pulses through the structure and listen for echoes, effectively performing automated ultrasonic inspections continuously. This technology is valuable for detecting internal flaws like cracks or corrosion patches that are not visible from the outside.

• Diagnostic Hardware Units: To drive the SMART Layer sensors, Acellent provides portable or installed data acquisition hardware. These units generate the electrical pulses for active sensing and collect response signals from the sensor network. They are built to be deployed on-site (some are even small enough to be placed on moving structures) and often have wireless communication capability to send data back to a central server. The hardware is optimized for high-speed sampling and can be programmed to run scheduled inspection routines on the structure.

• Software with AI Analytics: Acellent’s software platform analyzes the sensor data to identify damage and trends. It uses advanced algorithms to pinpoint the location of a crack or impact event and to assess damage severity (for example, estimating the crack length). The software incorporates machine learning and pattern recognition to improve damage characterization over time. It also integrates with IoT cloud frameworks – meaning engineers can receive alerts and examine structural health reports remotely via web interfaces.

Notable Projects:

• Bridge Monitoring Deployments: Acellent has applied its technology to bridges for real-world evaluation. In one pilot project, a highway bridge in California was instrumented with SMART Layer sensor strips on critical girders to monitor crack formation and growth under traffic loads. The system successfully detected hairline cracks developing in the steel girders and sent automatic alerts, demonstrating the potential to catch structural issues long before they become visible or hazardous.

• Aircraft and Aerospace Structures: Although outside civil construction, Acellent’s origins in aerospace showcase the capability of its SHM systems. The company’s sensors have been used on military aircraft fuselages and helicopter rotor blades to continuously check for fatigue cracks. This same technology is now being transferred to civil infrastructure; for example, concepts like monitoring wind turbine blades or large storage tanks for early crack detection are being tested.

• Large-Scale Infrastructure Health Programs: Acellent is involved in infrastructure monitoring programs where multiple structures are equipped with sensors feeding data into a centralized system. One example is a state-wide pilot in which dozens of aging metallic bridges and overpasses were each fitted with a small Acellent sensor network. The sensors measure strain changes and impact events (like vehicle strikes or seismic tremors) on the structures. All data streams into a cloud platform, giving transportation officials a dashboard of bridge health across their network, and highlighting which bridges may need maintenance or detailed inspections.

The company is known for integrating various sensor brands and types, choosing the best technology for each measurement task.

• Acoustic Monitoring Systems: A special capability Sixense offers is acoustic emission monitoring for prestressed cables and metal structures. They use sensitive acoustic sensors to “listen” for the sound of wire breaks or crack growth in critical components like bridge cables or tendons inside concrete. This real-time acoustic monitoring can catch sudden failures (like a snapping cable strand) immediately, prompting inspection crews to intervene before a minor break propagates into a serious issue.

• Data Management and Visualization Software: Sixense’s digital platform collates data from all installed sensors and presents it in user-friendly ways. Engineers and operators can view live sensor readings on dashboards, such as displacement graphs of a bridge span or tilt readings of a building over time. The software also provides automated alerting – for example, if a tunnel’s convergence measurements exceed a safe threshold, the system triggers alarms. Sixense often customizes these software systems to client needs, including predictive models and structural analysis tools that forecast future behavior based on the sensor data.

Notable Projects:

• Iconic Bridge Monitoring: Sixense has implemented SHM systems on many notable bridges globally. In France, the Île de Ré Bridge is equipped with more than a hundred sensors installed by Sixense to track bending, vibrations, and environmental effects on this long sea-crossing structure. Likewise, in Greece, the Rion–Antirion Bridge (one of the world’s longest multi-span cable-stayed bridges) relies on a Sixense monitoring system with over 300 sensors, including strain gauges on cables and accelerometers on the deck, to ensure its long-term performance against seismic activity and heavy traffic.

• Tunnels and Metro Systems: Sixense provides continuous monitoring for tunneling projects and operational tunnels. During the construction of the Crossrail tunnels in London (UK), Sixense instrumentation was used to monitor ground movements and existing building displacements in real time, using a network of automated total stations and tilt sensors. In operation, transit authorities have used Sixense’s services to keep tabs on tunnel linings – for example, the Paris Metro lines have sections fitted with sensors that report any structural shifts or water ingress, enabling proactive maintenance.

• High-Rise Buildings and Industrial Structures: Sixense has also worked on skyscraper monitoring in seismic regions. In one project, a tall building in Istanbul, Turkey was instrumented with a Sixense SHM system including roof-top accelerometers and wall-mounted strain sensors to monitor its response to earthquakes and strong winds. Additionally, Sixense has monitored nuclear power plant structures and offshore platforms – environments where their expertise in handling extreme conditions and strict safety requirements is crucial. Across these projects, Sixense’s combination of on-site sensor technology and remote data analysis has helped extend the life and improve the safety of critical structures.

Company 5: Pure Technologies – Overview, Notable Projects, Key Technologies

Pure Technologies is a company originally founded in 1993 in Canada that rose to prominence with its innovative approaches to infrastructure monitoring, particularly for water pipelines and large structures. Now part of Xylem Inc. (after an acquisition in 2018), Pure Technologies has a global footprint and is known for developing the SoundPrint acoustic monitoring system and other novel sensor-based solutions. Pure’s focus has been on providing asset owners with continuous information about the condition of their structures, allowing for a shift from reactive repairs to proactive maintenance. While their strongest niche is in pipeline and water infrastructure health, Pure Technologies has also applied its sensor expertise to bridges, parking garages, and buildings.

The hallmark of Pure Technologies’ approach is the use of continuous monitoring with minimal intrusion. For example, their SoundPrint technology can be installed in an existing structure without major modifications and will listen passively for signs of distress. Over the years, Pure has expanded its technology portfolio through R&D and acquisitions, including tools for pipeline inspection (using robotics and fiber optics) and structural monitoring sensors. By integrating these tools with software analytics, Pure provides clients with actionable insights – such as warning when a pre-stressed cable in a bridge is corroding or when a pipeline section is beginning to crack.

Key Technologies and Solutions:

• SoundPrint Acoustic Monitoring: This is Pure Technologies’ flagship sensor system for structures. It uses a network of highly sensitive acoustic sensors (basically listening devices) attached to a structure to detect the high-frequency sound signatures of wire breaks, cracks, or leaks. In a bridge, for example, SoundPrint sensors on the cables or beams will pick up the “ping” of a snapping steel strand or the crack of concrete micro-fracturing. The system can triangulate the sound source location and time, alerting engineers to a potential issue that warrants inspection. SoundPrint has been notably used in monitoring prestressed concrete water pipelines and suspension bridge cables around the world, where early detection of wire failures is critical.

• Fiber Optic Strain Monitoring: Pure Technologies has also employed fiber optic sensor systems for continuous strain and temperature monitoring. These involve running fiber optic cables along a structure (such as inside a pipeline or along a bridge deck) that can measure minute changes in strain over long distances. Fiber optic sensors are immune to electromagnetic interference and can cover large structures with a single cable. Pure has utilized this technology to monitor deformation in pipelines and also for dynamic monitoring of structures under load (since fiber optics can sample at high speeds to capture vibrations).

• Remote Data and Asset Management Software: Under Xylem, Pure’s solutions feed into cloud-based asset management software that helps infrastructure owners make maintenance decisions. Their software can combine real-time sensor data with predictive analytics – for example, estimating how many more wire breaks a bridge cable can sustain before its load capacity is reduced. By presenting this information in dashboards and reports, the technology supports a strategy known as predictive maintenance, where repairs or strengthening can be done just in time to prevent failures, rather than on a fixed schedule or after damage is visible.

Notable Projects:

• Suspension and Cable-Stayed Bridges: Pure Technologies has monitored several large bridges using SoundPrint. One example is the Jason Bridge (a pseudonym for a major North American suspension bridge for confidentiality) where Pure installed an array of acoustic sensors inside the main cables. Over years of operation, the system has detected multiple wire breaks within those cables, enabling the bridge owners to take maintenance actions (such as cable wrapping and dehumidification) to extend the life of the cables. Similarly, in Texas, Pure’s technology was used on a series of post-tensioned concrete bridges to catch tendon failures; the sensors successfully alerted officials to failing strands in the bridges’ tendons that were later confirmed and replaced.

• Water Pipeline Networks: Pure Technologies built its reputation on monitoring critical water transmission mains. For instance, the Washington Suburban Sanitary Commission (WSSC) in the United States employed Pure’s acoustic monitoring on large-diameter prestressed concrete cylinder pipes. The sensors continuously listened for the telltale “ping” of snapping steel pre-stressing wires in the buried pipes. Thanks to this system, WSSC was able to identify specific pipe segments that were deteriorating internally and replace them on a planned basis, avoiding catastrophic bursts. This approach has been recognized as a best practice in water infrastructure management.

• Parking Structures and Buildings: In addition to bridges and pipes, Pure has applied SHM sensors in structures like parking garages and high-rise buildings. For example, a multi-story parking garage that showed signs of cracking was instrumented with acoustic sensors and strain gauges by Pure’s team. The continuous data helped differentiate between normal crack growth and serious structural issues, guiding the repair strategy. In high-rises, Pure’s fiber optic sensors have been installed during construction to monitor how the building settles and moves over time, providing engineers with valuable feedback on their design models and assurance that the structure is performing as expected.

FAQs 

How do sensor companies in structural health monitoring improve construction safety?

Answer: Sensor companies enhance construction safety by enabling continuous oversight of structural integrity. They provide devices such as strain gauges, accelerometers, and crack sensors that are installed on critical components of a structure. These sensors deliver real-time data on stresses, vibrations, or movements. If the data indicate abnormal behavior (for example, an unusual spike in strain on a bridge beam or rapid widening of a crack), the monitoring system triggers alerts. Engineers and maintenance teams can then take immediate action to inspect and fix the issue before it leads to a failure. In essence, the technologies from sensor companies allow for early detection of potential problems, which significantly reduces the risk of accidents and catastrophic structural collapses.

What technologies are used by top sensor companies in structural health monitoring for construction?

Answer: Leading sensor companies in structural health monitoring use a variety of advanced technologies. Key examples include wireless sensor networks (battery-powered sensors with radio transmitters that send data without needing cables) and fiber optic sensors (which can measure strain or temperature changes along a structure using light signals). They also utilize vibrating wire sensors (a highly stable sensor type for long-term measurements in bridges and dams) and acoustic emission sensors (which listen for sounds of cracks or material failures).

Additionally, these companies provide sophisticated data loggers and IoT gateways that collect sensor data and upload it to cloud-based monitoring software. On the software side, technologies like machine learning and AI are used to analyze patterns in the sensor data, helping to predict future performance or detect subtle signs of damage that humans might miss.

Which structures benefit most from the solutions provided by sensor companies in structural health monitoring?

Answer: Virtually any large or critical structure can benefit from structural health monitoring, but certain types of structures see particularly high value. Bridges (especially long-span bridges and heavily trafficked highway overpasses) are prime candidates – continuous monitoring helps manage aging components and heavy load effects. High-rise buildings and towers also benefit, as sensors can track sway, foundation settlement, or seismic responses, ensuring the building remains safe over time.

Dams and hydroelectric structures use SHM to monitor pressure, leakage, and structural movements, which is crucial for preventing water inundation disasters. Other examples include tunnels (monitoring deformation and lining integrity), stadiums and large roofs (watching for excessive deflections or vibrations), and historical monuments that need preservation (sensors can alert if cracks in a heritage structure are growing). In summary, any structure where failure would pose significant risk or where maintenance is challenging benefits from the continuous insights provided by SHM systems.

Is it true that sensor companies in structural health monitoring offer predictive maintenance to prevent failures?

Answer: Yes. One of the major advantages of modern SHM systems is their ability to support predictive maintenance. Sensor companies achieve this by combining real-time monitoring with data analytics. The sensors continuously collect information on the structure’s condition – for example, measuring how strain on a bridge girder changes with each passing truck. Over time, the system learns what “normal” behavior is and can identify trends indicating deterioration.

Many companies integrate predictive algorithms that estimate when a certain component will likely need repair or replacement if current trends continue. For instance, if crack sensors on a parking garage show a crack growing a few millimeters every month, the system can project when that crack might reach a critical size. This allows maintenance crews to fix the problem well in advance of failure. While no system can predict every possible issue with 100% certainty, these technologies greatly improve foresight. They shift maintenance from a reactive approach (fixing things after damage occurs) to a proactive one (addressing issues before they cause downtime or safety hazards).
