Study On The Maturity Evaluation Of High-rise Residential Buildings In The Whole Process Of Cost Management

Today,high-rise housing has become the main form of housing in large and medium-sized cities in China.As one of the important types of residential construction,high-rise housing has the advantages of alleviating the urban land tension,increasing urban residential plot ratio and unit land development value.However,the high investment of high-rise residential buildings and the difficulty of construction have brought some difficulties to the owner's cost management.Therefore,to improve the cost management capability of the high-rise residential buildings throughout the process,the owners can reasonably determine and effectively control the cost of each stage of the project to achieve the project expectations Benefits are of great significance to enhance the competitiveness of enterprises.Based on the owner 's perspective,firsty,this article combines the maturity model theory with the high-rise residential whole-process cost management theory to define the concepts and dimensions of the high-rise residential full-process cost management maturity model,and discusses from three dimensions,which are mature.Degree level,high-rise residential construction process,maturity index system.When establishing the maturity evaluation index system,the data was obtained through a questionnaire method,and the data results were analyzed using SPSS statistical analysis software.Finally,the entire process of high-rise residential cost management with 5 primary indicators and 21 secondary indicators was established Degree evaluation index system.Secondly,based on the gray whitening weight function,a high-rise residential full-process cost management maturity model is established,the FAHP-entropy weight method is used to determine the index weights,and the gray whitening weight function clustering method is used for comprehensive evaluation.Finally,the established maturity model is applied to the actual high-rise residential project case,and its cost management capability is evaluated.It is concluded that the project owner's full-scale cost management maturity level is a normative level,and the evaluation results are consistent with the actual.According to the evaluation results of the case,corresponding countermeasures and improvement suggestions are proposed to enhance the owner's overall process cost management ability,and at the same time provide reference for the entire process cost management of other high-rise residential projects.
