Research On Risk Management Of PPP Project Based On BIM

The PPP project market in China has entered a large-scale development stage.The domestic and international practice research shows that the failure of the PPP project still exists because of the improper planning and the failure of the franchise period supervision and so on.The key problem lies in the poor information management of the construction industry.With the continuous maturity of BIM technology theory and practice research,based on the perspective of information management,BIM technology is applied to the PPP project with modern information technology as a means.By collecting and organizing the data of each phase of the project,the BIM information platform and the BIM operation and maintenance system are set up to realize the information integration management of the whole life cycle of the PPP project.Management and risk control will further open up the information channel between the government and social private enterprises,and promote the healthy development of PPP mode.Based on this starting point,this paper tries to combine BIM technology with PPP project risk management.The main contents of this paper include the following parts.First,based on the literature research,this paper combed the various factors affecting the implementation of PPP project,and combined with the questionnaire investigation,formed the PPP project risk list,including 28 risk factors.Secondly,the risk assessment model is established by fuzzy comprehensive evaluation,and the importance degree of PPP project risk and the key risk management objects are analyzed in detail.Besides,the specific application of BIM technology in PPP project risk management and control is analyzed in detail,including cost overrun risk and construction process risk.Finally,a PPP project in Qingdao is selected as the case study,and the application of BIM technology in this project is analyzed in detail,including the establishment of BIM organizational structure and the analysis of the function of the BIM team,and how to improve the risk problems of the BIM technology.To sum up,the results of this study effectively enrich the BIM and PPP project risk management theory,to improve the risk management level of PPP project and guide the construction of PPP project has certain guidance and solution value in the future.
