Research On Risk Sharing And Income Distribution In Construction Project Of IPD Mode

With the increasing demands of high efficiency,low cost,close cooperation and information technology,the traditional delivery mode can not meet the needs of the project construction.As a new delivery mode,IPD(Integrated Project Delivery,integrated project delivery mode)can effectively optimize the construction process of the project,improve construction efficiency,reduce the cost of the construction project,in order to promote the realization of the overall objectives of the project better.However,because many parties are involved in the construction process,the risk sharing and income distribution of IPD mode is more complex,which has hindered its application and development in the domestic construction industry.Therefore,it is significant that doing research on the risk sharing and income distribution of IPD mode.First of all,the paper reviews the development and research situation of the IPD model in the construction industry at home and abroad,introduces the aspects of definition,feather and organizational structure,finds that IPD mode is suitable for the AIAC195 contract,thoroughly analyzes the text of the contract,identifies the basic requirements of IPD mode participation and risk sharing and income distribution.Secondly,this paper makes a further research on risk sharing and income distribution of IPD mode.As to risk sharing,this paper uses the features of IPD mode to identify the risk of the IPD construction project,uses interpretative structural model(ISM)to clarify the relationship with various risk factors,divides the risk factors into the macro level,the medium level and the micro level.According to the principle of complete control,this paper establishes the risk index system,uses FAHP to calculate and identify the proportion of risk sharing.This paper bases on the principle of income distribution,identifies the content and mode of income as contribution,input and risk,establishes the income distribution model,uses the Shapley value method to identify the contribution of each participant,which only considers the contribution,and according to the principle of consistency of input and income,in the situation that only considers the contribution,identifies the income distribution of each participant,and according to the principle of the risk sharing proportion,identifies the income distribution of each participant which only considers the contribution.Based on the above study,this paper uses the gray correlation method to analyze correlation degree of the distribution of the income from the three aspects of contribution,investment and risk,identifies the income distribution of the participant.Finally,this paper makes a case analysis,puts forward the specific application of risk sharing and profit allocation method and calculates the proportion of risk sharing and income distribution,verifies that the method which is proposed in this paper has feasibility and rationality to provide reference for the IPD construction project risk sharing and profit allocation scheme.This paper makes a comprehensive research on risk sharing and profit distribution of IPD mode construction project,and provides a new method of risk sharing and profit distribution.This paper enriches the theoretical research on risk sharing and profit distribution of IPD mode,provides some theoretical guidance for the practical application and extension of IPD model in China,which can promote the development of high efficiency and information technology in construction industry of China...
