SEM - based construction cost analysis of prefabricated building

Prefabricated buildings have comprehensive advantages over traditional buildings, but the reasons for the incremental cost in the construction stage are complex and need to be solved urgently. This paper takes the prefabricated components that have the greatest impact on the construction cost of prefabricated buildings as the research object, divides the construction process of prefabricated components into three stages: production, transportation and site installation of prefabricated components, studies the interrelation of each stage in combination with the application of information technology system of prefabricated components, and establishes a model by using structural equation. The results show that the production cost of prefabricated parts has a positive influence on the transportation and installation cost. Transportation and the application of information technology have the greatest impact on construction costs; the production and assembly of prefabricated parts have relatively little influence on the construction cost.
