Study On The Delicacy Management Of The Project Cost Incurred In The Transaction Phase Of The PPP Project

In order to deeply improve the quality of building products of the supply side and strive to provide more high-quality and convenient public services for the social public,the construction projects of infrastructures and public services in today's China need more investments than ever before,which undoubtedly has greatly increased the financial pressure of governments at all levels.For the purpose of getting rid of this dilemma and accelerating the transformation of government functions,China has been actively promoting the application of the PPP(Public-Private Partnership)model in the areas of the construction projects of infrastructures and public services.The construction projects of infrastructures and public services,represented by urban integrated pipe galleries,municipal roads,high-speed railways,river crossing bridges and sea crossing bridges,have prominent characteristics such as the large amount of investment of a single construction project,the complicated factors affecting the project cost and the numerous effective points of controlling the project cost.The traditional “Owner's extensive” and “Governmental housekeeped” cost management models have been difficult to meet the new requirements of the current cost management of projects.So as to adapt to the requirements of the construction projects of infrastructures and public services and hope to manage and control the project cost more accurately and effectively,the paper carries out relative study on the theory and practice of the delicacy management of the project cost incurred in the PPP project.Firstly,the theory of PPP project transaction stage,the theory of delicacy management of the project cost and the theory of evaluating the cost of the prefabricated component are analyzed,which lays a theoretical foundation for the follow-up study.Secondly,on the basis of the traditional process of the project transaction stage,the process of the PPP project transaction stage is optimized.Next,the content of the delicacy management of the PPP project transaction stage is elaborated,including the composition and reviewing of the bidding documents,bid opening,evaluation of bids,determination of the bid,negotiation and signing of the PPP project contract,the composition and reviewing of the control price after the determination of the bid,the mutual second review of the control price after the determination of the bid and thesigning of the PPP project sub-contract.Thirdly,the deviation of the control price of the PPP project and its reason are studied.On this basis,the reasons for the deviation of the control price are analyzed.Then,the composition of the control price,the review of the control price and the second review and negotiation of the control price have been studied and discussed to clarity the method of the delicacy management of the control price.Fourthly,the contract system and contract documents of PPP project are briefly discussed.Then,the process of contract management of PPP project is studied and summarized.At the same time,the content of the contract management of PPP project is elaborated from two aspects of the mutual negotiation of contract terms and the management of supervision contract.Finally,the first-stage pilot PPP projects of the integrated pipe galleries in Changsha high-tech district and the municipal roads in Liaojiaping street were taken for instance,the application effect of the above theoretical achievements in the actual project was studied and discussed.Practice has proved that the research results of this paper basically meet the expected requirements of the delicacy management of the project cost and have the meaning of certain reference and guidance to the delicacy management of the project cost incurred in the transaction phrase of the similar PPP project.
