Abstract: The teaching of BIM will be a major topic in design implementation of landscape architecture in the next years as the building and construction industry worldwide transitions fully to the digital. This paper explains an approach to teaching Building Information Modeling (BIM) in landscape architecture and how digital grading and its application play a major role in a BIM site design project. Digital grading is the access road to BIM. Landscape architecture education must include the BIM modeling method, and process in its teaching.
