The Light Rail Way Station On The Ground Of Engineering Change Management In Cost Control Application Research

Light rail traffic has become a public travel choice, alone with the light rail is astraddle-type monorail traffic light, in the technology of straddle type monorail is anational initiative, in the local Chongqing straddle type monorail is the city’s first railtraffic, both have their "first "meaning.The straddle type monorail has multitudinous stations, therefore the author in ascientific and objective manner chose the straddle type monorail ground stations as theobject of study. Analys the monorail project change,to summarize the reasonabledesign change management measures, finally establish a scientific and rational designchange scheme selection model.First, describes the research background, puts forward the existing Chongqingstraddle-type monorail engineering change problem, significance and research at homeand abroad; the city track transportation cost and change management are summarized,and pointed out the existing research and lack of research links; elaborate on the detailsof contents.Secondly, the direct and indirect effects on cost management change, be necessaryto control cost;definition of the light rail engineering change, engineering changeclassification, and analyzes different types of change management focused, play acertain role in cost control; the simple description of the definition of valueengineering and its application in project change, theoretical basis for the engineeringchange.Thirdly, according to the analysis of two aspects of theory and practice, to find outthe characteristics of Chongqing straddle-type monorail change, the analysis of thecause of Chongqing straddle-type monorail change characteristics; from the actualcollected data analysis, found the design change occupy a considerable proportion inthe engineering change, as for the management of design alteration theory groundworknecessary and practical data support.Finally, the design is obtained by a section of the change of importance inengineering change in the proposed method, management of design change, designleads to establish the base of value engineering change scheme selection model based on a list of indicators, the indicators; role; how to use this model and thesignificance, finally carries on the example analysis. In the city of Chongqingstraddle-type monorail as an example, according to the characteristics of the mountaincity, combining with the data and information have, as well as model put forward inthe fifth chapter, join the instance data. Finally through the design change schemedesign than the selected model, achieve the straddle type monorail project changemanagement, project cost control effectively from a specific aspect.
