Research On Fine Cost Management Of Assembled Building Enterprise Based On EPC Model

With the increase of technical,economic and environmental requirements,the construction period of prefabricated production and assembly construction of assembly building is promoting the construction industry,and the construction mode of the lean construction industry with its short construction period,environmental protection and energy saving.The transformation and upgrading has injected strong vitality into the development of the construction industry.The EPC general contracting mode is the management mode of the key application of the prefabricated building project.Lots of construction enterprises actively upgrade into a prefabricated building enterprises and expand the assembly-type construction project business.In recent years,a large number of assembled-type construction EPC enterprises have emerged.Assembled building EPC companies are therefore in a challenging market environment,different from traditional building products,different business operations,targeted ways to reduce costs and methods to control assembly-type construction enterprises.Operating costs,thereby increasing the competitiveness of fabricated construction companies and traditional construction companies.In order to enable the EPC enterprise of the prefabricated building to realize the strategy of comprehensive and sustainable development and realize the maximization of enterprise benefits,the cost refinement management is the only way to improve the cost management capability and realize the core competitiveness of the enterprise in the era of “micro-profit” of such construction enterprises.way.The cost-refinement management is guided by modern and advanced cost management ideas.Through in-depth analysis of the various links of the business processes of the assembly-type construction enterprises and the links between the various links,it seeks ways and means to reduce the cost of enterprises and improve the cost management of enterprises.The efficiency and precision of the company enhances the core competitiveness and benefits of the company.In order to determine the content of cost management of EPC enterprise in prefabricated building,this topic firstly uses the WBS method to sort out the refined cost management content of the EPC enterprise of the fabricated building,and breaks down into the easy management and control independent according to theprocess involved in the cost management content.Unit,establish its cost-refinement management work breakdown structure;secondly,based on the above content,through the use of Hall three-dimensional structure,the paper studies the EPC enterprise cost refined management system from the three dimensions of logical dimension,time dimension and knowledge dimension.Framework;Then,based on the established three-dimensional system framework structure,the process integration(IDEF0)method in integrated management theory is introduced to analyze the process between planning,manufacturing,assembly and operation,operation and maintenance from the perspective of integration and integration.Integrate models to determine the direction and focus of process integration management.For the construction of the 3D cost refined management system and integration model,from the enterprise cost management process,namely,cost refinement forecasting,cost refinement planning,cost refinement control,cost refinement accounting,cost refinement analysis and cost refinement assessment.In this respect,the specific implementation plan of the cost refinement system is proposed,which provides an operational reference to fulfill cost-based management of the assembly-type construction enterprise.Finally,combined with a prefabricated construction enterprise to conduct case analysis and analyze the implementation effect.Applying cost-refinement management to a prefabricated construction enterprise can drive the advancement of prefabricated buildings,promote the transformation of cost management ideas in the construction industry,and improve the efficiency and competitiveness of enterprises.
