The Application of Building Information Modelling in Landscape Design for Ecological Protection

Over the last decade, the widely use of Building Information Modelling (BIM) has significantly improved the efficiency of architectural, engineering, and construction (AEC) industry in China. Many studies have been dedicated to how BIM could help in construction works. However, due to lack of BIM application in landscape filed, limited researches could be found on how many excessive works could be prevented by BIM and its ecological value in protecting local environment, especially for those hillside areas with relatively vulnerable ecosystem, which covers over two thirds of the land in China. This paper aims to set up a BIM-based landscape design workflow and examine its effectiveness in reducing construction waste produced in design process. One project case of hillside residential district planning design was carried out by applying the established BIM workflow, showing that earthworks were reduced significantly, and the final net cut/fill volume was controlled at 32.45m3 after project completion. Minimizing earthworks prevents the local topsoil and vegetation from been destroyed by unnecessary constructions. Utilizing BIM in landscape design enables the architects to pursue a more ecological and integrated design solution, paying more attention to the relationship between human beings and nature
