The investigations cover all aspects of the whole life cycle of a structure \u2013 from the design stage until demolition, which ranges over several decades. One aspect entails selecting and characterizing reliable and durable materials, including the service-life design in the design phase, especially for structures exposed to severe environments. During the service life, non-destructive condition assessment followed by performance prediction is of major importance, which could result in repair and rehabilitation and, in the worst case, demolition of a structure. In every phase of a structure&#8217;s life, in addition to the reliability of the structure, every decision in service life management affects the sustainability of a structure, which requires further decision-making. Our research provides the basis to design, build and sustainably maintain our structures with low emissions and resource efficiency in the future.<\/p>\n<p><strong>Research
