Your benefits

Six years is a long time for a structure

Between two main inspections, what determines the condition happens. Whoever knows the trend decides earlier and with better arguments.

The trend instead of a snapshot

The structural inspection provides one picture every six years. Monitoring captures the development in between and shows whether something is changing, how fast and in what context.

All measured variables in one place

Cracks, moisture, corrosion, tilt, vibration and movement run into the same portal. Instead of isolated readings without context, a picture of the whole structure emerges.

Retrofittable on existing structures

The sensors are wireless and need no continuous cabling. They can be cast into new builds and retrofitted to existing structures, without scaffolding just for the instrumentation.

Decisions backed by measurement data

Closure, remaining service life, refurbishment timing and inspection effort are decisions with money behind them. A measurement series backs them more reliably than an assumption in an expert report.

Inspection and monitoring

Inspection assesses, monitoring observes

Structural inspection to DIN 1076 is the expert assessment on site, at fixed intervals. Monitoring runs in between and makes visible what changes in the meantime. Together they give a complete picture.

Structural inspection

Main inspection every six years, a simpler inspection in between. Assessment by the inspection engineer, hands-on and documented.

Monitoring

Readings around the clock, with thresholds and automatic notification. Shows development and speed instead of a single state.

From objective to monitoring concept

Four steps before the first sensor sits

  1. 01

    Clarify the objective

    What should the measurement answer? Condition surveys during construction work, remaining service life of an ageing structure or observing a known defect lead to different concepts.

  2. 02

    Define the measured variables

    The damage pattern determines what is measured: crack width, moisture, corrosion, tilt, vibration, movement at a bearing or a combination of these.

  3. 03

    Plan the measuring points

    We identify the critical points on the structure and the number of sensors. A baseline measurement fixes the starting condition to which all further readings refer.

  4. 04

    Set thresholds and the alert path

    Every measured variable gets warning and alarm limits and a group of recipients. This clarifies in advance who is informed at which value and what happens then.

Explore measuring points

Where a structure is measured

Each point has its own question and therefore its own measured variable. Choose a point and see what is captured there and which solution stands behind it.

Measured variable

Crack width

Displacement transducers continuously record the change in crack width. It becomes visible whether a crack is dormant or active, and how it responds to temperature and traffic.

To crack monitoring

All measured variables

Seventeen solutions under one roof

Which of these come together depends on the question. Often it is two or three that explain each other.

The applicable standard depends on the measured variable. Vibrations are checked against the limits of DIN 4150, structural inspections to DIN 1076, construction work on the track to RIL 883.8100A01. We assign this within the monitoring concept.

Single source

One point of contact for the entire monitoring

From the free concept through installation to ongoing evaluation in the online portal, we accompany you through the whole project, as a complete solution, not isolated parts.

Matching sensors

The devices behind the measured variables

Structural health monitoring means combining several measured variables on one structure. These are the devices that most often come together.

Typical use cases

When an assumption becomes too costly

Closure, refurbishment and replacement builds are decisions involving large sums. A measurement series shifts them from an estimate to the data.

  • Accompany ageing structures through to the planned replacement build
  • Condition surveys at neighbouring buildings during construction work
  • Observe known damage between two main inspections
  • Support remaining service life with measurement data instead of assumptions
  • Keep structures with restricted accessibility permanently in view
  • Provide evidence towards clients, authorities and insurers

For operators

Maintenance by condition instead of by calendar

Whoever knows the trend brings measures forward where they are needed, and defers them where the measurement series stays calm. That is the basis for reliable refurbishment planning.

For engineers and inspection engineers

Data for the structure file

The measurement series are historised and exportable and are available at the next inspection. The assessment remains with the inspection engineer, the data basis is better.

FAQ

Frequently asked questions about structural health monitoring

What is structural health monitoring?
Structural health monitoring, also called structural monitoring, is the continuous sensor-based monitoring of a structure. Instead of a snapshot during an inspection, a continuous measurement series emerges for the variables that determine the condition: crack width, moisture and corrosion in the concrete, tilt and settlement, vibration and movement at bearings and joints. The trend reveals whether damage is developing, how fast and under which influences.
Does monitoring replace structural inspection to DIN 1076?
Inspection to DIN 1076 remains in place and is complemented by monitoring. The main inspection provides an expert assessment on site every six years, monitoring the development in the years in between. The measurement data feeds into the structure documentation and is available to the inspection engineer. The assessment remains theirs.
Which measured variables can be monitored?
Crack width, moisture in the concrete, corrosion at the reinforcement, tilt and settlement, deformation, vibration and peak particle velocity, movement at bearings, groundwater level and pore water pressure, deflection of roofs, leaks and the opening of manholes and doors. Which of these come together depends on the objective, not a catalogue.
Can an existing structure be retrofitted?
Yes, that is the standard case. The sensors are wireless and need no continuous cabling. Sensors are bonded, bolted or inserted via core drilling, gateways are powered by solar module or battery and reach even remote structures. Scaffolding just for the instrumentation is not required for this.
How do the measurement data reach me?
The sensors send their readings via gateways over the mobile network into the cloud-based Infrasolute software. There they are presented graphically, historised and fitted with warning and alarm limits. You can check the condition online at any time and are automatically notified by email or SMS when a threshold is exceeded. The passive concrete sensors are additionally read on site with a reader.
What does structural health monitoring cost?
That depends on the structure, measured variables, number of measuring points and duration, which is why we do not quote a flat rate. The concept is free with us: you tell us about the structure and the question, we propose measured variables, measuring points and thresholds and state the cost within it.
