Research On The Collaborative Management Of Engineering Construction Based On Cloud-BIM

BIM technology has been gradually developed from stage application to depth application.Integrated with a variety of advanced information technologies,BIM technology provides strong technical support for solving many technical problems in the process of project construction.The huge scale and advanced design ideas of modern projects put forward higher requirements for the construction technologies of the construction organizations;at the same time,they also put forward higher requirements for the way of project management.In the mode of construction general contracting,a series of management problems(such as numerous participants,the complex tasks,a large and scattered amount of information,multi-disciplinary intersections and so on)seriously affect the efficiency of engineering construction.Therefore,it will be a trend to meet the needs of engineering construction management by making full use of the cutting-edge technology innovation management methods,upgrading or transforming management tools.Based on the way of social network analysis of Cloud-BIM collaborative management implementing,through the analysis of the centrality of the points and lines in the binary directed network diagram,seven key demand factors are obtained.In response to these seven key demand factors,this paper sets up the theory system of Cloud-BIM collaborative management,providing a feasible and comprehensive collaborative management scheme for the construction general contracting unit in the actual construction process.The main research results are as follows:(1)Through dividing the dimension of collaborative management objectives,detailed design management is included in the scope of responsibility of the construction contractor,which can undertake the collaborative management in the construction stage.This paper also sorts out the responsibilities of BIM work among relevant participants in the project construction and the functional departments within the general contractors.BIM workstation is positioned as information integration deployment center in the management organization structure,and the project management organization structure centered on the general contract contractors is restructured based on this.(2)The whole collaborative work process of each participant is combed in this paper,and the working mechanism of Cloud-BIM collaborative management is put forward.This paper explores the Cloud Computing and BIM technology after the information integration of Cloud-BIM platform,and it also sets the permissions of each participant in the platform.Furthermore,the information collaboration and organization collaboration are realized,and the Cloud-BIM-based collaborative management theory system of engineering construction is constructed.(3)From the perspective of the requirements of Cloud-BIM platform for collaborative management function,the framework of Cloud-BIM collaborative management platform is designed,including detailed design management system,construction management system,knowledge management system,platform management system.This paper sorts out the information transmission relationships among the various systems,and also compiles the workflows of single-line and multi-line among the various functional modules under each system.(4)The level of management in detailed design will have a direct impact on the construction;as a result,in the process of collaborative management platform framework design,according to the detailed design management and its system,this paper proposes the detailed design management control system,which includes one work system and four management systems.Through this system,the complex work is transformed into progressive linear work,and the four management systems can effectively strengthen the supervision and control of the detailed design work.This ensures the accuracy and efficiency of the work in the detailed design phase,while ensuring the information in the detailed design phase transmitted completely in the construction phase.(5)A hospital project in Yantai was selected as a case study to integrate the actual project situation and the existing management model of the construction contractor with the results of this paper,which include organizational structure,work responsibilities,division of responsibilities of each participant in Cloud-BIM platform and workflow.Detailed design management,the inspection of quality and safety and schedule management are selected as three application points for practical application,in order to promote the implementation of collaborative management,test the practicability and explore the shortcomings.
