The research activities in the field of monitoring of structures and components can be divided into the following areas:

• Structural Health Monitoring of bridge structures
• Material and component bank

The institute has a large experience in the monitoring and testing of bridge structures, particularly in condition assessment through the analysis of dynamic and static behaviour. In collaboration with the Bridge and Road Administration in Luxembourg, in-situ tests were conducted on intact bridges prior to their demolition.

This allowed for gradual damage introduction and the investigation of its effects on the bridge structure. This led to the development of the Deformation Area Difference Method (DAD method) and the application of most modern measurement techniques such as photogrammetry and drones, with ongoing intensive research in these areas.

To fully harness the potential of a circular economy in the construction industry, the reuse of components from old buildings at their end-of-life must be promoted as a key driver of sustainability. A major obstacle to this is the uncertainty regarding the guarantee of components for reuse. Therefore, a thorough condition assessment of these components is required to determine their remaining capacity and lifespan. Existing literature often does not address the consideration of physical factors such as geometry, aging, location, and environmental influences like temperature and humidity in the condition assessment. The goal is to develop an innovative model that integrates these factors and facilitates the transition of components from old buildings to new construction. The model will be embedded in a BIM-based digital system, which will be continuously updated with relevant information throughout its use. This will allow future building planners to easily identify the availability and condition of reusable components at any time.
