The Application of n-D BIM in Chinese Construction Projects

With the introduction of the concept of n-DIM and the advancement of research, the application of BIM in the architecture, engineering and construction industries, engineering and construction industries has been widely recognized, but it has not been clearly and deeply studied in construction projects in China. This chapter is concerned with studying the application of n-D BIM in China, from 3D BIM to 7D BIM. Firstly, based on literature research, this paper outlines some related concepts such as n-D BIM and SWOT analysis. Secondly, a Tencent Questionnaire is used for online distribution and collection, and SPSS 25.0 is used for descriptive analysis, difference analysis, multiple response analysis, etc. Finally, the strengths, weaknesses, opportunities and threats of n-D BIM in China’s construction projects are determined by SWOT analysis. Through cross-analysis, a series of strategies for promoting the development of n-D BIM are obtained. The results indicate that the recognition of n-D BIM application in Chinese construction projects is at the lower-middle level, poor overall utilization, insufficient management engagement with the software and a lack of supporting conditions. Visualization, high implementation cost, unified promotion and lack of BIM training are the four primary strengths, weaknesses, opportunities and threats of n-D BIM at present.
