基于云计算的建筑全生命期BIM集成与应用关键技术研究

According to the existing deficiencies and urgent requirements of applying current BIM technologies to the AEC/FM industry, this research proposes a BIM architecture framework for various stages and applications in building lifecycle, based on industry foundation classes (IFC) standard and cloud computing technology which is a newly-emerged IT technology worldwide. Then, a progressive and multi-participants oriented modeling method is established, followed by in-depth researches on some key technologies, such as distributed storage and management of BIM data, BIM data integration and fusion, sub-model extraction, BIM server and application mechanism based on process, etc. Finally, a cloud-computing-based BIM integration and server platform (BIMISP) will be developed. The purpose of this research is to present a set of theories, methods and technologies, and develop an integrated platform, to support BIM data sharing, lossless delivery and application among the whole building lifecycle including planning, design, construction, and operation and maintenance phases. The prospective findings will be useful for improving efficiency and quality of building activities, reducing resource consumption, and implementing sustainable development strategy during building lifecycle.
