BIM-based Building Permits: An Assessment of The Current State and Prospects in Germany and Internationally

Abstract

The ongoing digital transformation is catalyzing significant shifts across various industries, including the construction sector. A central focal point of this transformation lies in the realm of Building Information Modeling (BIM), where the digital model of the building provides the basis for the innovative method. This transparent and collaborative approach increases process efficiency and reduces the susceptibility to planning errors. This study examines the impact of the digital transformation on the building permit process, both in Germany and on a global scale. It encompasses a comparative analysis of civil and construction projects. The methodology encompasses a systematic review of relevant literature from international databases, coupled with a nationwide survey of permitting authorities within Germany. This dual approach aims to illuminate the expectations and perspectives of personnel working within German building administrations and to contrast these with the international landscape. The primary objective of this study is to conduct a comparative assessment of the status of digital and BIM-based permitting processes while identifying best practice examples. By adopting an international perspective, the research provides valuable insights into industry standards and charts a course towards a more efficient and streamlined future for the building permit process within Germany. Results of this study reveal that the digital transformation has indeed influenced the building permit process in both Germany and on a global scale. However, compared to countries like Singapore and Estonia, Germany lags in implementing BIM-based building permit processes. The study emphasizes the importance of learning from global best practices to enhance Germany's construction sector.
