| At present,China is in the period of rapid development of industrialization and urbanization.Speeding up railway construction and development has become an important national development strategy,which is of great practical significance to promote the sustainable development of economy and society.Railway construction and operation involves a series of different stakeholders or participants.As the builders of railway projects,the cost management level of construction enterprises has an important impact on maximizing the overall benefits of enterprises and promoting the rapid and good development of railway engineering projects.Based on this,how to improve the cost management level of railway construction enterprises has become an urgent problem.Taking GG railway project as an example,this paper focuses on the cost management of railway project.In this paper,based on the summary of project cost management,earned value method and other related theory and application research,combined with their own work practice,the cost management of GG railway project is studied.Firstly,the general situation and organizational structure of GG railway engineering project,the existing cost management mode and operation situation,key impact events,etc.are analyzed in detail.Then,according to the general situation and overall objective requirements of GG railway engineering project,the overall planning of project cost and schedule control is made,mainly including WBS decomposition,division of work responsibility,determination of work sequence and schedule It includes five parts: preparation and cost plan preparation,and selects "December31,2011" and "December 26,2014" as the interim inspection node and final inspection node.Finally,on the basis of defining the three basic parameters of BCWS,BCWP and ACWP,the earned value method is applied to GG railway project to check the deviation degree between the actual cost schedule and the expected plan,find out the reasons for the deviation,and give the deviation solutions.It provides a reference for the cost optimization of railway engineering projects,and also provides a reference for the cost control of other industries in China. |
