This paper summarizes the current status of BIM application in a number of large-scale landscape architecture design projects of a German-based landscape architecture firm during the years 2016 and 2021. In light of the increasing amount of infrastructure projects where Building Information Modelling (BIM) is applied, the knowledge spreads that only with BIM can competitiveness be ensured and new assignments obtained. An approach to projects based on BIM offers many significant advantages. These could be less need for reworking, fewer mistakes, better collaboration generally, and layout data which can be used in retrospect to support operation, maintenance, and property management. Clients that request infrastructural buildings, including public authorities, do not want to forego these advantages and increasingly demand the use of BIM in their projects. The current BIM experience is shown by several projects explored in this paper.
