Implementation of SHM in existing bridge structures

The structural health of bridges is a crucial point of attention for municipalities, provinces and asset managers in the Netherlands. Due to the increasing ageing of bridges and higher traffic loads, Structural Health Monitoring (SHM) is increasingly used as a smart solution to ensure the safety and lifespan of this infrastructure. But how do you successfully implement SHM in existing bridge structures?

Bridges under pressure throughout the Netherlands

In regions such as the Randstad, North Holland, Zeeland and Limburg Hundreds of bridges are under constant stress from heavy traffic, vibrations and weather influences. Traditional inspection methods are inadequate to detect damage early. This increases the risk of failure, traffic disruption and high repair costs.

What is SHM and why use it on existing bridges?

Structural Health Monitoring (SHM) is an advanced monitoring system that uses sensors to continuously measure the condition of bridges. Think of strain, vibration, deflection, temperature and cracking. By applying SHM to existing bridges, managers can:

• Early detection of problems (predictive maintenance)
• Track critical components in real time
• Plan reinvestments based on measurement data
• Meet stricter safety standards and audits

Technical and organizational approach to SHM implementation

Successful implementation of SHM in existing bridges requires a structured approach:

1. Construction analysis and risk profile

Map the current state of the bridge. Based on construction type, age and usage load, it is determined where sensors should be placed.

2. Selection of suitable sensor technology

Depending on the type of bridge (steel, concrete, movable or fixed), different sensors are selected, such as:

• Strain gauges and accelerometers
• Inclinometers and fiber optic sensors
• Wireless IoT sensors for hard-to-reach locations

3. Installation with minimal disruption

Installation often takes place during scheduled maintenance times. Many sensors are plug-and-play and wireless, which speeds up the process.

4. Data integration and visualization

The sensor data is linked to a central data platform, where administrators can track deviations, trends and alarms in real time.

5. Continuous evaluation and maintenance

Based on the measurement results, maintenance measures are implemented in a timely and targeted manner. This extends the lifespan and significantly reduces the chance of failure.

Take the next step towards data-driven bridge management

Are you responsible for bridge management within a municipality, province or water board in the Netherlands? Then consider a SHM pilot for an existing bridge in your area. Our specialists support feasibility studies, sensor selection and implementation – with specific experience in, among other things, South Holland, Twente, the Amsterdam region and the Brabant cities.
