Research On The Key Influencing Factors Of Cost Control In Assembled Buildings

In recent years,in order to further increase the development of green buildings and energy-saving buildings,the state has vigorously supported the development of fabricated buildings.Many companies have also made useful attempts in the main structure of fabricated buildings and achieved certain results.However,compared with the United States,Japan,Singapore and other countries,the development of China's assembly-type building is still in a relatively backward stage.Among them,the cost control of assembly-type buildings is low,resulting in the high cost of assembly-type construction has become a hindrance to assembly-type construction.One of the main reasons for development.The paper is based on this study of the key factors affecting the cost control of prefabricated construction,and strives to proceed from the key influencing factors and propose corresponding cost control countermeasures to provide a certain degree of promotion for the development of prefabricated buildings in China and to enhance the cost control of prefabricated buildings in construction enterprises.Reference for reference.Through literature research and questionnaire surveys,the paper analyzes the characteristics of prefabricated buildings and divides their cost components into four phases: design stage costs,construction production stage costs,transportation stage costs,and construction stage costs.The research of the paper centers on The four stages of cost control mainly do the following:A related overview and theoretical analysis of cost control for prefabricated buildings.Firstly,the related concepts,status quo and problems of prefabricated buildings and project cost control are analyzed.Secondly,relevant theories are expounded,including project cost management theory and structural equation model related theory introduction.Identification of the influencing factors of cost control for fabricated buildings.Using literature research,preliminary identified part of the cost control influencing factors;using the case analysis method as a supplement to further identify the influencing factors of the cost of assembly-based construction;finally,by summing up,analyzing,summarizing and integrating,the impact of assembly-type construction cost control was determined.List of factors.Applicability of the structural equation model and model assumptions.The applicability of the structural equation model in the dissertation is analyzed.Based on the identified cost control factors,the theoretical model of the structural equations of the influencing factors of the cost of the prefabricated building is constructed and the hypothesis test is performed.Empirical analysis.A survey questionnaire on the importance of the cost control factors of the prefabricated building was collected to collect the relevant data,and the reliability and validity of the questionnaire were tested.The structural equation model was used to fit,evaluate and correct until a good fit was obtained.The structural equation model validates the theoretical model,validates the hypothesis test results,and then analyzes the empirical results.Assembly construction cost control countermeasures.Aiming at the identified key factors that affect the cost of construction-based construction control,combined with the theory of project cost management,a corresponding proposal for cost control of assembly-based construction is proposed.The dissertation has studied the key influencing factors of assembly-based construction cost control in depth.According to the key influencing factors,it proposes corresponding countermeasures for construction-based construction cost control.The research results can not only enrich the theory of assembly-based construction cost control,but also provide Raising the cost control level of prefabricated buildings provides reference for reference,which has certain theoretical and practical significance.
