The Study Of Evm Method For Actual Applications In The Bill Of Quantities Mode

With the domestic construction market gradual opening up,the BOQ valuation method which is the general valuation method in the international construction market has been used widely.The using of BOQ is more and more perfect and go with the International standards,when the new BOQ valuation method has published in2008.How to take full advantage of the BOQ to control the target of construction investment, that is a worthy problem to studyExperience has shown that,after the total investment of construction project determined,more the70percent investment will consume in the phase of the construction.In this phase,saving investment is almost imposable,but there are many uncertain factors in construction process,these factors would cause project investment out of control.So during the construction phase, it is necessary to control the investment target effectivelyThis article analyzes the cost form and the pricing characteristics of BOQ,under the premise of the assumption that the quality of construction project is stationary,from the angle of construction supervision,on the basis of the home and abroad theory and research of Earned Value Management method(EVM) which is a common project management method in international,trying to build a method and process which would fit the required of construction projects under the BOQ mode,use to control the target of investment and duration simultaneously. It can effectively solve the practical problem that the investment goal and the duration goal can not be controlled simultaneously in the course of our country engineering supervisions’work.In this paper,author put forward the theory and principle that investment and duration target integrated management in construction project,and analysis the key elements of earned value management theory in the process of construction projects deeply,including Setting up the Work Breakdown Structure (WBS) based on the BOQ,building the determine baseline of earned value management performance index, Selecting the forecasting methods and indicators of the project earned value management,using the data of Progress payment settlement to set up the structure of investment and duration targets control data,analyzing the reason of control target deviations and selecting the appropriate methods to correct the deviations. Finally, use the target control processes and methods which has been set up in actual cases, achieve using Earned Value Management method to control both investment and duration targets and monitor the conduct of them, then qualitative analysis and correct the deviations of measurement and payment data, in order to achieve the purpose that controlling the construction project targets systemically. At the same time, it can promote supervisors to understand Earned Value Management deeply, provide technical tools and implementation for more systematic and in-depth construction project management, guide construction projects management running healthily and effectively.
