The Research On The Key Factors And Their Integration Of Collaborative Design For Industrialized Housing Based On The Use Of BIM

In the period of great change on information technology,there are many bottlenecks on the development of industrialized housing:the level of informatization being not high,the degree of industrialization being not adequate and the industrial scale being not large enough.The main contents and aim of this dissertation are to increase efficiency of industrialized housing development and to realize the informatization and industrialization of industrialized housing by using collaborative design pattern based on BIM tools.Besides the introduction and the conclusion,this dissertation is divided into three parts:research on the basic theories,research on the key factors,the integration of all key factors and application methods.In the introduction part,the contents of this research are presented after the analysis of the previous research;and the preliminary methods,key technologies and working ideas for the research are also described.Chapters 2 to 3 are about the basic theory of the collaborative design for industrialized housing.In chapter 2,the development history of industrialized housing is described.The reason of impeding industrialized housing's development is analyzed.It also indicates that industrialized housing needs to learn from manufacturing industry and its design pattern should transform from linear pattern to collaborative pattern.It comes to the conclusion that collaborative design should be used as the research starting-point for the industrialized housing.In chapter 3 the basic viewpoints and the development of the industrialized housing are introduced,the definition and the characteristics of the industrialized housing are pointed out,and some key technologies for the collaborative design of the industrialized housing are summarized.Chapter 4 is about the key factors and their order of importance.In this chapter,the key factors which may affect the collaborative design through literature review and expert interviews are firstly determined;some basic data about collaborative design by using questionnaires are then collected;through the data analysis,the five key factors and their importance ranking which can be used as the basis of the following research are finally concluded.Therefore,the first part of the dissertation is the groundwork for the research about collaborative design of the industrialized housing.Chapters 5 to 7 are the systematic description about the key factors.In Chapter 5 a comprehensive platform based on the BIM technologies is set up.It creates an implementation framework which can be extended for the collaborative design and provides a feasible implementation route.In Chapter 6 several methods which are based on BIM for the conflict resolution of collaborative design are concluded through the summarization of some operation methods for the conflict detection of collaborative design.In Chapter 7 the principles and management process for the BIM model library of components for industrialized housing are stated.Part 2 is the technology basis of the research.System-based integrated mode for the collaborative design of industrialized housing is discussed in chapter 8.It puts forward a system-based integrated mode based on BIM and IPD for the collaborative design which can solve the difficulties in collaborative design of life circle.This mode is not only the answer to the key factor "collaborative design for life circle" in chapter 4,but also the result of the integration of all key factors.Through this mode all key factors will be integrated together to form a systematic methodology.Based on the analysis of the content,the target and tools for collaborative design,systemic application methods are summarized in chapter 9.These methods will serve as operation basis for development and construction of industrialized housing.This research work is summarized in the conclusion part.The related works and future trends of research in this field are also listed.
