Assessment of the Effects of Deferred Maintenance on the Current Technical Condition of a Building: Case Study—A Former Fire Station in Nowy Raduszec

The degradation of building elements progresses with the age of a building as a result of natural ageing processes. The lack of regular maintenance, repair, and renovation works during the operational phase accelerates degradation processes, leading to the deterioration of the building’s technical condition and a decline in its functional performance. One of the primary responsibilities of building owners and managers is to maintain buildings in an appropriate technical condition throughout their entire service life. Deferred maintenance results in consequences of varying severity, ranging from minor defects, such as deterioration of aesthetic appearance, to major technical failures affecting the continued usability of the building. The aim of this study is to analyse the effects of deferred maintenance. The research analyses are illustrated by the example of the former fire station in Nowy Raduszec. The research was based on the assessment of the building’s technical condition and the prediction of changes in its functional performance. The obtained results confirmed that deferred maintenance constitutes a natural factor accelerating the building ageing process and adversely affecting the overall condition of the building.
