Research On BIM Technology Application Risk Based On EPC Mode

With the continuous and rapid development of my country’s construction industry,the pace of marketization is also accelerating.The investment method and management mode of construction projects have also undergone profound changes.The choice of the market has promoted construction companies from general construction contracting to EPC.The transformation of the model(integration of design,construction,and procurement),especially the formal implementation of the "Management Measures for General Contracting of Housing Construction and Municipal Infrastructure Projects"(referred to as the "Management Measures")issued by the Ministry of Housing and Urban-Rural Development,has accelerated the development of the EPC model The progress of market popularization indicates that the EPC model will be the strategic direction for the transformation of the construction industry in the future.The promulgation of the "Management Measures",jointly led by the Ministry of Housing and Urban-Rural Development and the Development and Reform Commission,strengthened the determination of enterprises to transform and accelerated the pace of transformation from general construction contracting to the EPC model.If the emergence of CAD(Computer Aided Design)improves design efficiency and transforms paper drawing into computer drawing,thus triggering a revolution in the design method of the construction industry,then the emergence of BIM(Building Information Modeling)will lead to architecture The value of the second revolution of the industry is even greater than the first revolution.The value of CAD is only reflected in the design stage,while the value of BIM lies in the full life cycle of construction projects(design,construction,operation and maintenance),and it faces a wider range of objects..The Ministry of Housing and Urban-Rural Development of the People’s Republic of China issued a series of documents for the promotion of BIM technology,which further promoted the development of BIM technology in the construction industry.It is foreseeable that the use of BIM technology in the EPC model is an inevitable trend in the digital transformation of the construction industry.However,under the current form,the application of BIM technology is not mature enough.The use of BIM technology in the EPC model can avoid certain risks,but there are still Part of the risks need to be studied and dealt with.First of all,this paper studies the advantages and disadvantages of the EPC model,combined with the related theories of BIM technology,analyzes the application of BIM technology in the EPC model,and through researching relevant domestic and foreign documents,initially establishes 26 risk factors,and then adopts the Delphi method to The 26 risk factors were revised,combined with the characteristics of the EPC model,and some currently inapplicable factors were deleted.19 risk factors related to the BIM application of the EPC model were summarized,and the 19 risk factors were sorted according to the characteristics of the risk factors.Classification,summarized into 5 categories,and established a risk level indicator system.Secondly,through comparative analysis of the currently used risk evaluation methods,combined with the research objects of this article,the fuzzy hierarchical risk method combining qualitative and quantitative is selected as the risk research evaluation tool of this article,and an actual engineering case of an EPC model in Guangdong is used.Constructed an EPC model BIM technology application risk evaluation model,and used the fuzzy analytic hierarchy process to obtain the weight of risk factors and the project risk evaluation grade.Finally,based on the risk factor weight table of the EPC model BIM technology application,this project is analyzed,the proportion of the weight of risk factors,and put forward different countermeasures to the corresponding risks.Based on the results of the EPC model BIM application risk assessment research,this paper provides a useful reference for construction companies that adopt BIM technology in the EPC model,and reduces the impact of risks.
