The Whole Process Cost Management Of Hydropower Construction Project

With the rapid development of China’s hydropower projects，the cost management ofhydropower projects has become the focus of the construction enterprises. By thetraditional planned economic management model affects, hydropower construction projectslack of a comprehensive and systematic method of cost control. Projects widespread thethree-overbudget phenomenon: the proposed budget over estimate, budget over theproposed budget and the accounts over budget. In order to improve the competitiveness ofenterprises of China’s hydropower construction and increase the economic benefits ofconstruction enterprises, it is important to establish a complete system to adapt to the costmanagement of hydropower projects. This article will discuss the cost management of theconstruction stage of the project cost management system using the method of combiningtheory and practice.(1)This article briefly describes the mode of foreign construction project costmanagement, analysis of the problems of China’s hydropower construction cost of theproject characteristics and construction cost management, described in detail of theinevitability, scientificity and rationality of the whole process of cost management modelused in hydropower construction project cost management.(2)on the basis of in-depth analysis of cost management model, with the main lineof cost forecast, cost planning, cost control, cost management of the scientific process. ncost forecast stage,Use can effectively reduce dimension of the principal componentanalysis and avoid the local optimum RBF artificial neural network established costforecast phase of cost estimation model, In cost plan management phase, Put forward theconstruction enterprise should implement multi-level management layers of managementthoughts level, Further clear organizational structure and function, Work out the cost of themain elements of the control measures, In order to achieve the effective control of the costsof the purpose of the spending,In the cost control stage,Based on the genetic algorithm isestablished cost balance optimization model, In time to ensure that under the premise ofwithout delay make construction cost in the rational flow of project, Achieve costequalization purpose.(3)for the case of a hydropower construction project, Using the whole process ofcost management mode stage of the project cost estimates, the cost of the programmanagement stage, cost control in the construction stage of detailed analysis and research,establishing a more complete cost management system. Provide more theoretical basis forthe whole process of cost management for the success of China’s hydropower constructionenterprise application project, to increase the controllability of the hydropower constructionproject cost management, improve the effectiveness of the whole process of costmanagement, promote the development of faster and better cost management andconstruction of China’s hydropower construction projects.
