The rapid development of BIM technology proposes higher requirements for the configuration of hardware resources, which can lead to exorbitant cost for simply upgrading hardware. This paper builds a virtual cloud desktop using desktop virtualization technology based on IDC (Internet Data Center) hardware and network resources. The combination of the BIM technology and virtual cloud desktop technology is able to meet the needs of 30 users at the same time, to build a BIM exclusive cloud desktop with personalized configuration of hardware and software, and to achieve the configuration upgrades only using the thin terminals, intelligent terminal or existing PC devices. The goal is to create a convenient, safe, efficient, low-cost and energy-saving way of work, and to provide technical support for BIM collaborative design, construction management and professional operation and maintenance.
