| With the implementation of our country’s strategy of "one belt,one road" and the increasingly intensified economic globalization,it brings unprecedented opportunities to the development of the construction industry,.At the same time,it provides higher requirements for construction project management.Under the environment of increasingly fierce competition in the construction market,enterprises must constantly improve and enhance their own cost control level if they want to achieve considerable development.In the whole process of engineering construction,the construction stage is the highest proportion of capital investment.It is also the key stage of the whole management process.Therefore it is significant for the construction enterprises to strengthen the cost control during the construction period of the project.JH company is a large state-owned construction enterprise.It established a set of cost management system for the construction period after a long period of developments.However,cost overrun occurred in the early stage of C project construction,so there is plenty of room for improvement in cost management during the construction period.In this paper,the theory and methods of project cost control are combed in detail.It uses the earned value method to analyze the status of the construction cost management of the JH company C project.It is found that there are some problems in the cost management of C project,such as backward concept of cost control,careless consideration of cost forecast,ineffective dynamic control of cost and imperfect responsibility system.According to this problem of construction cost management,this paper attempts to solve it by PDCA cost control mode.It involves making a dynamic plan for cost control,executing dynamic cost planing,assessing the effects of cost control by use of earned value analysis method,Summarizing the experience about dynamic cost control.As a result,PDCA cycle for dynamic cost control is formed.After multiple cycles,project cost and schedule are controlled in coordination.Through theoretical research and practical analysis,this paper draws the following conclusions: Earned value method can realize the cooperative control of construction project cost and schedule,avoiding the disadvantages of evaluating project cost control by a single index.At the same time,the utilization of PDCA cost control mode can effectively improve the cost control level during the construction period of the project.In view of these problems of construction cost management,the earned value method is applied to analyze the cost of the project.Then the paper optimizes the construction scheme,so as to coordinate the construction cost and construction schedule by PDCA cost control mode.The cost of labor,materials and machinery has been effectively controlled.So this cost control approach has been successful on the project.It can provide a reference for other construction companies to improve the level of construction cost control and improve the efficiency of cost management.As a result,the market competitiveness of enterprises continues to improve. |
