Study On The Dynamic Cost Control Of Real Estate Project Based On Contract Planning

With the national macro policy regulation and the intensified of industry competition, the real estate market is becoming more and more standardized,and profit level gradually return to rational, The traditional “post-accounting” cost management theory has been unable to meet the needs of real estate enterprises, so the cost management concept of contract planning is gradually introduced and widely recognized. Because there are many problems in the process of its practice, so we need to clarify the impact of the introduction of contract planning methods on cost control, and research on the specific content of the method and the problems in its practice to improve the contract planning cost control system and make the contract planning method play the value of the cost control.Firstly, based on the development and present situation of cost management theory, methods and cost management system, this paper uses the method of literature research, investigation, case analysis to expound the basic theory of the cost management of contract planning and the current situation of the practice in the field of real estate, and the introduction of multi-dimensional matrix WBS model is initially proposed to solve the problems in the practice of dynamic cost control system.Secondly, the cost management factors of contract planning control system is decomposed, and based on this to build a two-dimensional matrix of the related elements, construction of the multi-dimensional matrix WBS dimension by increasing tissue dimension and engineering dimension, at the same time combined with multi-dimensional matrix WBS and full life cycle cost management theory to construct multi-dimensional matrix WBS model from the perspective of the whole life cycle.Thirdly, multi-dimension matrix WBS is applied to the whole process of dynamic cost control system. To study and discuss the concrete working principle, process and method of each stage in the dynamic cost control system.Finally, through the research of NZ enterprises’ project J, empirically analyzes the second phase of the project J based on the practice of dynamic cost control of the contract planning, and summarizes the key factors in achieving effective cost control.This research provides a workable method for dynamic cost control of real estate project. It can effectively improve the efficiency of dynamic cost control in real estate project, and promotes the reform of the construction industry and real estate development enterprises. At the same time, it can also provide reference for the future study of the cost control system.
