Interface Management Of Cost Management Through Whole Processes Of Building Project

In recent years, in our country engineering construction domain, how to assign the fund which invested in the project reasonable, enabled these projects to obtain the maximum economic efficiency and the social efficiency by the most economical way, will be one of core questions which current urgently awaited to be solved.Although at present, we have already established the entire process construction cost management idea, realized to the entire process construction cost management necessity, but there still had many problems in the entire process construction cost control, have affected the entire process construction cost management effect. Traces to the source, we has not pay attention even to neglect in the entire process construction cost management process contact surface management.Therefore, develops to the items of basic constru -ction entire process construction cost contact surface management studies into the urgent matter.This article first to give the definition of entire process construction cost management,the entire process construction cost intersurface management, and introduce the intersurface elementary theory, namely characteristic and classification of intersurface, intersurface contradictory formation and law of development and so on.On this foundation this article has discussed intersurface management countermeasures in view of the intersurface contradictory establishment period, the divergent period, the running-in period, the stationary phase and the crisis time and so on various stages.On the basis of the intersurface management theory and the entire process construction cost management theory, has established the entire process construction cost management intersurface system,and analyzes the intersurface barrier and the reason of the entire process construction cost management from macroscopic and the microscopic two aspects.Through analysis the intersurface contradictory formation and reason during the entire process construction cost management,discuss the essence of cost management gradualness comes apart the phenomenon. Proposes the pointed solution and the measure.It includes: The enhancement of project integration management thought, establish the coordinated mechanism,the fuzzy control,strength contract management, use the information technology fully and so on.This article finally study how to appraise the entire process construction cost, intersurface management level of the building project.Proposed based on the analytic hierarchy process building project entire process construction cost intersurface management hierarchical indicator structure, analyzes in different environment, in the different situation various targets relative importance, provides the help for the management decision-making.Utilizes the grey system theory and the fuzzy mathematics method, designs the entire process construction cost inteersurface management level appraisal the pessimistic cluster method, to estimate the entire process construction cost intersurface management level.This article research has certain guiding sense to our country items of basic construction entire process construction cost management, specially cannot link up well to at present items of basic construction various stages construction cost management, have gradualness to come apart the phenomenon, but how to use the theory to the items of basic construction entire process construction cost management practice also needing truly further the thorough real diagnosis research.
