Contact Surface System Analysis And Research In The Building Cost Of Projects Management

In recent years,the building cost of projects management's theory weeded through the old to bring forth the new unceasingly,the hundred flowers contended,"the entire life cycle construction cost management" the theory,"the entire process construction cost management" the theory,"the comprehensive construction cost management" the theory was the fundamental research achievement,at the same time,the contact surface concept also gradually appeared in the construction cost domain.The contact surface is a concept of the system theory,in the building cost of projects management develops gradually in the process,the contact surface concept is also introduced in which.In the building cost of projects system the project contact surface divides into the technical contact surface,the contract contact surface,the organization contact surface,the entity contact surface.These contact surfaces involve the engineering project each aspect,profound influence project expense,progress,quality.From the angle of strengthened the construction cost control supervisor,it has the important theory significance and the practical significance regarding engineering project's in each kind of contact surface's analysis and the research.This article takes building cost of projects system's in project each kind of contact surface as the object of study,obtains from the influence construction cost's various seeds contact surface, carries on the analysis to each kind of contact surface,establishes the technical contact surface,the contract contact surface,the organization contact surface,the entity contact surface three big subsystems.This article key the technical contact surface subsystem,the contract contact surface subsystem carries on the multianalysis,through the graph union example elaboration technology, the contract contact surface and the construction cost relations,has summarized the organization contact surface and the entity contact surface subsystem,proposes some guiding principle to each contact surface subsystem's interface management.Finally this article proposed in the conclusion part the establishment perfect quantification index system's predict that the perfect interface management,causes interface management from the fundamental research to the practice application spanning,becomes the building cost of projects management the practice means and the tool.
