1.3 Concrete and steel in buildings structures – Expected life prediction for maintenance

Challenge

In this project, we address the challenge from a socio-economic perspective by developing a model to support decision-making. We use, among other things, cost–benefit analysis to estimate the costs and benefits associated with extraneous water and the measures taken to reduce it. In addition to purely economic aspects, we also include social and environmental factors, such as the inconvenience caused by basement flooding and the environmental impact of overflow discharges into lakes and watercourses.

Other key components of the project include analyzing how different system boundaries affect the results, and how and in what way measurements in the sewer network should be conducted to maximize positive impact.

Expected results

This project evaluates sensor-based inspection technologies using drones. This inspection method can help streamline and future-proof inspection processes. Drone inspections provide a clear overview of the condition of concrete structures, and this condition can easily be monitored over time.

Another tool for evaluating maintenance needs of concrete structures is the simulation of their condition over time. For example, chloride concentration and pH levels in the concrete can be estimated for a specific structure in a given geographic area.

Societal Impact

• Drone inspections can support and simplify the inspection of concrete bridges.

• Simulations of how concrete structures change over time can support future inspections.

• A foundation for more efficient and future-proof inspection methods.
