A very important task to improve the sustainability of existing structures is to extend their service life especially in terms of resource conservation and sustainability. Therefore, the assessment and the required safety level of an existing structure are of particular importance (condition monitoring). This contribution focusses on how data from established inspection and monitoring approaches are essential and examines the more advanced, additional approaches currently under review. Both the load‐bearing capacity and the serviceability must be guaranteed over a certain period of time at or above the required safety level. The serviceability of a structure can be measured by performance indicators. It is examined how the definition and measurement of performance indicators in conjunction with a well‐designed life cycle management action can be used to extend the service life while ensuring safety levels.

“…When the condition of a structure has been assessed, the question arises as to how this will develop in the near future and what the remaining service life will be. In addition, extending the service life of buildings and structures has an enormously positive effect in terms of sustainability [2].…”

One very important contribution to improving the sustainability of existing structures is to extend their service life. This also makes a valuable contribution to resource conservation. Therefore, the assessment and the required safety level of an existing structure are of particular importance. This is one of two contributions which together summarize the past, current and developing approaches to extending service life while ensuring safety. Herein it is presented the reasons why many existing structures no longer meet structural safety requirements. Both the loadbearing capacity and the usability must be guaranteed over a certain period of time at or above a certain safety level. It is examined how these, and their future development, can be reliably assessed by collecting and analysing key data and how this can be used to extend the service life of structures.

“…The assessment of existing NB structures is nowadays often based on the subjective visual evaluation of the examiner or the responsible consulting engineer. However, designing new NB structures and evaluating existing NB structures as conducted with common engineering methods, does not yet include all the relevant information needed to predict the structural behaviour over its lifetime [1][2][3][4][5]. The inclusion of information from visual inspections as well as information, which, due to the technical progress of monitoring systems, is feasible but is not yet performed regularly, has great potential to improve the accuracy of condition assessments and the prediction of the remaining service life for NB constructions.…”

Railway noise barrier constructions are subjected to high aerodynamic loads during the train passages, and the knowledge of their actual structural condition is relevant to assure safety for railway users and to create a basis for forecasting. This paper deals with deterministic and probabilistic approaches for the condition assessment and prediction of the remaining lifetime of railway noise barriers that are embedded in a safety concept that takes into account the damage consequence classes. These approaches are combined into a holistic assessment concept, in other words, a progressive four-stage model in which the information content increases with each model stage and thus successively increases the accuracy of the determined structural conditions at the time of observation and the forecast of the remaining service life of the structure. The analytical methods used in the first stage of the developed holistic framework are based on common static calculations used in engineering practice and, together with expert knowledge and large-scale fatigue test results of noise barrier constructions, form the basis for the subsequent stages. In the second stage of the data-driven condition assessment and life cycle analysis approach, linking routines are implemented that combine the condition assessments from the visual inspections with the additional information from temporary or permanent monitoring systems with the analytical methods. With the application of numerical finite element methods for the development of a digital twin of the noise barrier in the third stage and the probabilistic approaches in the fourth stage, a maximum determination accuracy of the noise barrier condition at the time of observation and prediction accuracy of the remaining service life is achieved. The data-driven condition assessment and life cycle analysis approach enables infrastructure operators to plan their future investments more economically regarding the maintenance, retrofitting, or new construction of railway noise barriers. Ultimately, the aim is to integrate the presented four-stage holistic assessment concept into the specific maintenance and repair planning of infrastructure operators for aerodynamically loaded railway noise barrier constructions.
