Project: Life cycle management for bridges

The life cycle management (LZM) allows to optimally manage large stocks of bridges. Monitoring data help to describe the condition of the building better and allow better statements to be made about key performance indicators (KPI), such as the remaining useful life and life cycle costs.

In this project we have developed an overview of methods and areas of application of monitoring procedures for bridges. In doing so, we consistently formulated the validity of monitoring results on the condition of buildings and finally the KPI and developed a concept for a monitoring-based LCM. Pilot studies illustrate the applicability.

The result allows an optimization of the LZM at network level, it reduces forecasting uncertainties for essential KPIs, enables more reliable multi-year planning with derivation of the investment requirements and finally a better allocation of scarce resources. The work can also be transferred to other portfolios such as energy (e.g. offshore wind), infrastructure (e.g. bridges and tunnels) and building construction with the aim of supporting optimal decisions in LCM and extending the useful life.
