Research On Investment Control Of General Contracting Project In Employer's Perspective

The construction industry is the pillar industry of the national economy.The rapid development of the construction industry,the continuous improvement of construction capability,the continuous expansion of the industrial scale,driving a large number of related industries,have made important contributions to the development of economy and society and the construction of new urbanization.At the same time,our country has built a large number of landmark projects with advanced design concept,large construction difficulty and high quality in super high-rise buildings,high-speed railway and other fields with great difficulty,large volume and complex technology.However,the construction industry is still large and not strong,the way of construction organization is backward,the system and mechanism of supervision is not perfect,and the architectural design level needs to be improved.These problems have restricted the overall competitiveness promotion of the construction industry.Therefore,in order to promote the sustainable and healthy development of the construction industry and improve the mode of construction organization,China has taken the lead in implementing the general contracting mode in government investment projects and prefabricated buildings.The general contracting mode is an internationally accepted mode of construction project organization and implementation.In our country,vigorously promotion to the project general contracting is conducive to enhancing the project feasibility study and preliminary design depth,and realizing the in-depth integration of various stages of design,procurement and construction so as to improve the level of engineering construction and realize the ultimate functional value of the project.However,at the present stage of the Chinese construction market context,the trust environment and risk culture are not yet mature,the employers only follow the international practice of general contract under the premise of trust and copy the contract system and pricing method without corresponding check and balance mechanism,likely causing out of investment control in the general contracting project.Based on the above theoretical basis,this paper from the perspective of the employer,carries out the research on investment control of the general contracting project as follows:First,study on the structural process of the employer's requirements list of the general contracting project based on QFD.First of all,clarify the application process of employers' requirements list in general contracting project and its important role in the investment control.Then,determine the framework based on the contract model,policy guidance and actual cases,and identify the exact employer's requirements by the prototype approach.Finally,put forward the employer's requirements as the input of the quality function development,and realize the structural development into the four phases of "employer's requirement-implementing element-project objective-function index".Second,study on investment control goal's determination of the general contracting project based on the functional cost method.Firstly,based on the theory of target cost management theory,analyzes the important role of setting the employer's investment control goal and reasonably determining the process of the investment control goal.Then,using the salient function modules as the evaluation unit and seeking the similar function modules based on fuzzy clustering,accurately determines the investment estimate with the functional cost method.Finally,regulate and review the initial design by the employer of the general contractor,including functional review,feasibility review and economic review.Third,study on the price adjustment risk about investment control of the general contracting based on the vulnerability diagnosis,First of all,based on the contract and policy provisions,diagnose the investment control target system's own vulnerability of the general project and identify vulnerability through the contract term;and then based on the literature and cases,identify the price adjustment risks of the general contracting project that employer should bear,and match with the vulnerable point of the target system.Finally,after the occurrence of the risk events,the employer conducts the blame analysis,the vulnerability diagnosis and the price adjustment review respectively to ensure the accuracy of price adjustment.To sum up,based on the theory of target cost management,this paper uses the methods of literature review,quality function deployment,functional cost method and vulnerability diagnosis,through the structure of the employers' requirement list,the reasonable determination of the investment control objective and the effective control of the employer's price adjustment risk,establish a set of investment control system of general contracting project adapted to China's application scenarios,to provide practical and theoretical support for the employers to complete the investment objective and achieve the ultimate value.
