Analysis Of Factors Affecting Construction Cost Of Prefabricated Buildings And Study Of Control Measures

With the vigorous implementation of sustainable development in China,traditional cast-in-place buildings are gradually eliminated due to their pollution of environment and waste of resources,replaced by prefabricated buildings.However,when prefabricated buildings are used,their high construction cost becomes an obstacle in the process of market promotion.This thesis compares the construction costs of prefabricated buildings and cast-in-place buildings,finds out the cost differences and analyzes the influencing factors,seeks for the cost control measures of prefabricated buildings,in order to provide reasonable Suggestions for the popularization and development of prefabricated buildings.This thesis firstly USES case analysis method to find the cost difference between prefabricated building and cast-in-place building.Secondly,based on the cost control theory,22 factors affecting the construction cost of prefabricated buildings are screened out by literature analysis and frequency statistics.Thirdly,the case analysis and questionnaire survey were used to add and delete the preliminarily determined influencing factors and score their importance.Finally,17 influencing factors were determined and classified according to design dimension,production and transportation dimension,installation dimension,policy dimension and coordination dimension.Then,the entropy method is used to determine the weight of 17 influencing factors and determine the main influencing factors.Finally,according to the categories of influencing factors,the main causes of high construction cost of prefabricated buildings are put forward targeted cost control measures.The research on the influencing factors and cost control measures of prefabricated building in this thesis provides reference for the effective control of prefabricated building construction cost and is conducive to promoting the process of construction industrialization in China.
