Research On Integrated Management Of Urban Rail Transit Project Cost Under Agent Construction System

Urban Mass Transit is entering the phase of rapid and orderly development, which will usher an unprecedented large-scale construction. At present, China's Mass rail transit are characterized with divers form,high investment. The high project cost has become a barrier to thriving urban mass transit. Facing the large-scale construction tasks and urgent need for cost control, agent construction system will provide an opportunity as an international more sophisticated construction management model.The urban mass transit project cost management is studied under the premise of agent system in this dissertation, incentive and restrictive mechanism mode,cost risks/ income distribution model of the construction contract and all elements integrated model of the implementation phase. It researches on the composition, methods and measures of Total Factor Cost Management. It puts forward new ideas and methods for project cost management. Main innovations are:(1) The incentive and restraint mechanisms for urban rail transit construction cost management are designed. It clearly analyzes the rights and responsibilities of all parties from the main parties and their relationship through constructing game model with the application of principal-agent theory. The main measures of incentives and constraints are identified.(2) The cost risks and income distribution model are elaborated basd on the urban mass transit project construction contract. The traditional method of risks and income distribution coefficients for contract has been changed which provides a clear quantitative method for the determination of the ratio coefficients. It makes cost management more scientific.(3) The methods and measures of the total factor cost management in phase of urban rail transit construction implementation are prompted. It breaks the traditional ideas of project cost management, innovating the application of comprehensive cost management thinking.It optimizes project cost in the whole process under the guidance of Life Cycle Cost Management Thought, and introduces Total Factor Cost Management. It gives an integrated research involves all elements on the various stages, improving the urban rail transit project cost management.
