Research On Payment Control Of Specialty Sub-contract Project Of Prime Cost Sum

With the rapid development of the construction industry, large and extra largeconstruction projects is gradually increasing, and the implementation of many projects areincreasingly complex,which makes specialty sub-contracting work to become an inevitablechoice. Prime Cost Sum of Specialty Sub-contract Project is a kind of sub-project, andsubcontractors can be determined by the employer and contractor in BQ in China. AlsoConstruction Contract (Demonstration version)（2013）proposed that the employer, the contractorand the subcontractor the signed the Prime Cost Sum contracts of tripartite whensubcontractors determined by the employer and contractor.However, there is no relevant thePrime Cost Sum contracts of tripartite at home, which result in a serious problems thatpayment is arrearsed and plague the smooth progress of the project. There are two aspects ofthis reason, one is due to the penment contents is not clear, especially the price adjustment, onthe other hand is the payment process have objections. Therefore, in order to ensure PrimeCost Sum of Specialty Sub-contract Project’s payment well paid, the paper achieve thepayment control through the configuration of the rights of control,and the analysis of paymentadjustment,and the improvement of payment processes.The risk-sharing of parties involved in the contract and the process of contract paymentare eestricted by the rights of control of project. The risk-sharing of parties involved in thecontract should match with the rights of control of project,and the process of contractpayment will different with the different the contract price of rights of control.So the basis ofrisk-sharing of parties involved in the contract and the process of contract payment is theconfiguration of the rights of control in Prime Cost Sum of Specialty Sub-contract Project.Meanwhile, the risk-sharing of contract payment adjustment factors will also affect theprocess of payment. Shows that the improving of payment process is based on theconfiguration of rights of control. Based on the above analysis, the main research contentsare as follows.Firstly, the rights of control of sub-projects are abstracted by analyzing constructioncontracts model text abroad through applying summary method. Then analyzing configurationof the rights of control of general subcontracting and nominated subcontracting,finding thatthe differences and incentives, this gives the recommendations that configuration of rights ofcontrol of Prime Cost Sum of Specialty Sub-contract Project in tripartite contractualrelationship.Secondly, identify the risk factors affecting contract payment of Prime Cost Sum ofSpecialty Sub-contract Project through the analysis of each construction contract template based on Text-analysis model. And then dividing the responsibilities of risk factors Combinedwith the theory of risk-sharing, in order to determine the causes and conditions of the contractpayment adjustment and adjustment method.Thirdly, based on Determining the payment points in the both construction contract orgeneralizing the payment points tripartite agreement in the presence of project practice,combining with the particularity of Prime Cost Sum of Specialty Sub-contract Project, todetermine important content of advance payment,interim payment and final account atcompletion. Then improvement of payment progress of Prime Cost Sum of SpecialtySub-contract Project would be conducted.
