Research On Qingrong Railway Preliminary Cost Management And Control

Railway plays a very important role in the social and economic activities， as therailway construction in China has entered a period of rapid development， investmentgrowing，shortage of funds has become the major problems faced in the developmentof Chinese railway， railway construction project cost effective identification andcontrol of more and more attention. At early stages of railway construction projectinvestment control effect obvious phase， there is an urgent need to strengthenresearch， to effectively control investment.In this paper， theories and methods to pre-determine and control of project coston the basis of the China Railway Construction System， the main railwayconstruction project pre-investment estimates， estimates from the investment andinvestment estimates of the underlying data for troubles and propose a completeestimation process，and finally combine the features of the early railway constructionproject cost control， and preliminary cost control methods and measures.The first program of basic construction of the railway construction project tosummarize and clarify the cost determination process based on the analysis ofcorresponding with the cost to determine the various stages of railway constructionproject cost to determine the method and basic investment estimate for the currentproposed budget， the budget is relatively complete specification actually out of line，clear of the early railway construction project cost control focus on investmentestimated，it is the investment to estimate the improvement of elementary data accessand investment estimation methods.Followed by estimation methods on existing investments and summarized， theintroduction of content，including uncertainty analysis and risk analysis of investmentestimation accuracy of the analysis to establish a computational model， and theinvestment in railway construction projects to estimate the original process， whichstandardized and accurate estimates for the investment to provide a guarantee.Control theory is based on the full life cycle of the project cost in the railwayconstruction project cost control phase， the integrated use of value engineeringoptimization， quota design， life cycle cost analysis methods and measures to ensurethat the goals of early railway construction project cost control.
