Implementierung der Circular Economy in den Modulbausektor : Identifikation und Bewältigung sektorspezifischer Anforderungen auf der Grundlage eines Strategiemodells

The construction industry is one of the most resource- and waste-intensive sectors. Currently, singular planning perspectives in construction projects steer the focus especially towards a more efficient orientation of the execution as well as the operation phase. In addition, traditional project delivery methods in the building construction and infrastructure sectors predominantly include only the design and construction of the building facilities. At present, there is hardly any holistic consideration of all lifecycle phases and the lifecycle costs incurred by a building facility.In addition to ecological and social benefits, the concept of the Circular Economy also provides economic incentives for companies to proactively counteract the linear view described above and the increasing challenges posed by climate change and the growing scarcity of resources. In view of the stationary manufacturing conditions and modularity, among other things, the modular construction method represents an ideal starting point for implementing the concept of the Circular Economy in the construction sector.The overall objective of this dissertation is to conceptualize a holistic contribution to the implementation of the Circular Economy in the modular construction sector, taking into account the specifics of the German construction market, thus contributing to support the transformation process towards a sustainable German construction industry and providing a research basis for further scientific penetration of the topic in the future. In detail, a yet non-existing strategy model for the implementation of the concept of the Circular Economy for modular construction manufacturers in Germany will be developed, taking into account the sector-specific requirements. The strategy model and the associated recommendations for action serve as a framework for integrating the concept of the Circular Economy strategically and holistically, for making it professional, replicable and controllable, and for implementing it effectively.
