Resource allocation methodology of virtual desktop infrastructure in cloud computing BIM: Focusing korean small and medium sized architectural design firm

BIM (Building Information Modelling) technology has been expanded for using in construction project during the past 20 years. However, recently its spread has been delayed than the initial expectations, due to the high-cost of BIM infrastructure development, the lack of regulations and process. In design phase, especially, collaboration based on BIM system has being a key factor for successful next generation building project. In the many analysis of current research about virtualization and BIM service, convergence of cloud computing and virtual server system can be proposed as a most successful solution for data exchange such as drawing, 3D model, object data, properties,. Therefore, this study has a purpose DaaS(desktop as a service) for BIM user design phase by phase. By analysis user's desktop resource data from Predesign phase to Schematic design, Design develop and Construction design phase, we defined criteria to resource distribution on virtual desktop environment. The goal of the study is to enable the BIM customized cloud computing server. It will bring cost saving, high-performance quality of working environment and cooperation's convenience and high security when doing BIM work in small and medium sized architectural design firm.
