Civil Engineering

Monitoring has never been so easy

Solutions for All Types of Assets

Key Advantages

Our AIMsight structural health monitoring (SHM) offers comprehensive advantages over other monitoring solutions across all civil engineering applications.

  • Global measurements: A single camera monitors the global behavior of a span. It can also make measurements of the displacements of columns and pile caps due to scour, settlement, or landslides. These displacement measurements are more direct than an inclinometer measurement and often easier to interpret.
  • Dynamic SHM: Perform modal analysis and follow extreme events. High-speed video-based enables remote vibration measurements. The main modes can be measured remotely, without accelerometers!
  • Durable: Passive markers tracked on the image. No batteries or electronics in hard-to-reach locations.
  • Remote diagnostics: The camera-based system enables a global remote diagnosis after special events (earthquakes) or abnormal sensor readings, with potential visual identification of the cause
  • Verifiable SHM: Interoperability with land surveyor measurements, image data available to check the context of the measurements. Remote visual inspection by certified inspectors is available on demand.
  • Scalable: Leverage the progress of image sensors with our dedicated edge-processing camera or with your own cameras and our cloud-based SHM solution
  • Extensible: We offer a state-of-the-art crack monitoring system for the continuous inspection of cracks on metallic structures, see here. Our UPEC front-end electronics and our AIMcloud platform can accommodate a wide range of sensors relevant to civil engineering.

Customer Value

  • Standardized and synthetic overview of the structural health state of many structures
  • Prioritization of the maintenance projects to focus on the structures where abnormal settlements, deflection, or vibration have been detected
  • Understand the root cause of cracks or premature degradation
  • Consistent data enabling a machine learning approach to aging mechanisms

Bridges

Bridges are aging, and maintenance resources are not sufficient. State-of-the-art processes cannot cope with the problem. The situation will become increasingly acute as more bridges built in the ’60s and ’70s reach the end of their design life. As a consequence, bridges are failing, and more may do so in the future.

We provide remote inspection systems able to measure bridge deformation, displacement, and cracks to deliver continuous data compliant with professional standards. The key advantage of our solution is its low cost and easy implementation, which does not require traffic interruption or heavy work on the structure.

As illustrated above, a single camera can monitor many points (10 to 100) and capture a wealth of information about the bridge state evolution as well as behavior:

  • Static and dynamic span deflections
  • Bridge sway and vibrations
  • Pile cap displacement due to scour or settlement
  • Column and pier displacement due to scour or settlement
  • Pillar displacement and sway
  • Bridge/deck position shifts due to accidental collisions
  • Thermal expansion joint and bearing motion
  • Traffic-induced thermal expansion joint and bearing motion

Static and Dynamic Span Deflection Measurements

Deflection and sag measurements are useful for evaluating the condition of bridges, in particular, that of prestressed concrete structures that are often difficult to inspect.

For example, an increase in the deformation of prestressed concrete structures was measurable before the failure of the Morandi Bridge. The sag increased over 10 years, with a marked acceleration over the last year, see https://www.mdpi.com/478498.

In addition to static deformations, dynamic deformations under vehicle load as well as vibration data captured by the AIMsight camera system, can track a reduction in the stiffness of the structure.

Bridge Applications Portfolio

Buildings

Capture global building motion or slab deflection, whether during the commissioning or as part of lifetime extension measures, with the AIMsight system. These measurements are particularly useful when coping with older prestressed concrete structures, where a direct assessment of tendon health is often impossible.

Dynamic deflection measurements are performed of these prestressed concrete slabs. These give meaningful inputs in structures where the state of the tendons is degraded or unknown.

The facade of this landmark building is monitored using an AIMsight solution, with two strain gauges per steel column measuring abnormal roof load transfers.

Tunnels

Control subsidence of the ground around the tunnel as well as tunnel convergence.

  • Data shared with all stakeholders: Experts, engineering firms, construction company
  • Web access to the data + construction metadata such as construction phases/events
  • Detailed assessment of settlement causes and amplitudes before reaching a built zone
  • Pinpoint the most critical phases of tunneling work and quickly adapt techniques based on the findings.
Prisms used for tunnel convergence measurements
Surveillance of ground subsidence over a wide area over the tunnel front. 45+ markers are tracked with a single system!

AIMsight for Railway Applications

The AIMsight autonomous optical measurement system is ideally suited for a wide range of monitoring and measurement applications on and around railway tracks. Its compact design and ease of deployment — including the option to operate on battery power for short-term campaigns — make it a flexible solution for both dynamic and long-term monitoring needs.

Key Applications: Track and Infrastructure Monitoring

  • Optical 2D displacement monitoring of rail ties and track sections.
  • Detect track displacement during construction activities near rail corridors.
  • Long-term observation of rail curves, embankments, and terrain stability.
  • Continuous monitoring of railway bridges to document compliance, optimize restoration work, and perform commissioning load tests with confidence.

Railway Station Monitoring

Monitoring the deflection of prestressed concrete prefabricated elements in station environments.

Providing long-term assurance of structural integrity in high-load areas.

Track Behavior Monitoring

Dynamic Rail Motion Measurements: Capture transient behaviors such as vibration, emergency braking events, or the effects of passing rolling stock.

High-precision, real-time measurement of 2D rail motion under operational loads.

Railway Bridge Monitoring

Achieve more targeted restoration work and document the compliance of older structures. Commission new structures with confidence by performing load tests and efficiently achieving real-time monitoring.
