Research On The Key Factors Of Collaborative Design Management Of Large Project Under The Design General Contracting Management

With the booming development of China’s construction industry,architectural design technology is constantly updated,among which co-design has been applied in the process of architectural design.In order to improve the efficiency of architectural design,co-design is mainly to organize resources in the collaborative process,reduce the design cycle reasonably.But in the practice of the collaborative design process also exposed some shortcomings,especially in large projects in collaborative management show problem is more apparent,the reason is that a large project in the design process is facing such as the construction of large scale,complex technology,coordinate the participation subject more,high quality and functional requirements of many influence factors,Therefore,how to apply collaborative design method to solve many challenges in large projects,in order to achieve efficient management of project architectural design becomes particularly important.However,at present,the maturity of architectural co-design and management is not high,and its application needs continuous research and exploration.In recent years,the rapid development of emerging technologies such as virtual reality,the building information model,prefabricated building,further promote the popularization of the collaborative design.The method of co-design and management has become an important direction to study.The efficiency of architectural design is decided by application of management and vision in co-design’s perspective.In this study,the main factors of co-design were defined and labelled by analysing various literature about the engineering procurement construction.Then,experts in related fields of architectural co-design were selected to attend in-depth interviews,and their opinions and suggestions on the influencing factors of co-design management about the engineering procurement construction were collected.Their opinions and suggestions would be used to establish framework of factor hierarchy and co-design management.Moreover,the hierarchical structure model of the main factors has been accomplished by experts’ perspectives which based on scoring method and results from term weighting analyse.After the main factor hierarchy model was set up,using the AHP analytic hierarchy process(AHP)to calculate term weight factors and importance degree.At the same time,relative weight and combination weight of every hierarchy were calculated.The actual significance of the weight should be exposed and given after calculating.Finally,the practical engineering case of C project is introduced to explain the effect of project which accomplished by co-design management,analyzed problems in this case,and presented improvement methods and suggestions.
