A Study On The Cost Control At Construction Stage Of Architectural Project Based On Earned Value Method

With the steady growth of investment in infrastructure construction in China,the domestic construction industry has gradually accelerated.In the context of the continuous development of the construction market,construction enterprises are facing fierce market competition,we must find a favorable way to enhance their core competitiveness.The construction stage of the architecture project is the stage of the largest proportion of capital investment in the whole process of construction,which is also the key stage of the conversion of funds into a building entity of the critical stage,so the cost control of the construction stage is the main way to obtain the economic benefits for the construction enterprises.In the promise of ensuring the quality and duration of the project,the construction enterprises must always control the cost of the project with the budget.Exploring the cost control during the construction phase will improve the investment system reform and the management level of the construction enterprises.Firstly,this paper systematically studies the basic theory of cost control in the construction stage,including the connotation,principles and specific steps,etc.,and describes the main methods of the cost control in the construction stage in detail,including value engineering,activity-based costing,linear regression method and earned value analysis,whose basic concepts,principles and other contents are all analyzed.Especially,the earned value method is recognized to be the rational method in the process of cost control.Secondly,this paper analyzes the cost control of a university's teaching building project using earned value analysis.After briefly introducing the project profile,we analyze the progress and cost of the construction stage,and find the deviation between the actual value and the planned value in the construction process,and put forward the corresponding corrective measures.Finally,the paper puts forward some suggestions on how to strengthen the cost control in the construction stage,including building the early warning system of cost control,strengthening cost management in the construction process including material costs,mechanical costs,labor costs and non-productive expenses,establishing the system of cost responsibility through the responsibility distribution of the cost controland enhancing the cost management of non-productive activities to reduce the cost of non-productive activities for the cost control tasks of the construction project.
