Research on Cost Management of Prefabricated Steel Structure Housing
To scientifically and effectively manage and control the cost of prefabricated steel frame residential buildings,an approach was initiated by addressing the source of cost generation,identifying,and subsequently screening 25 influencing factors.This led to the construction of an impact indicator system for prefabricated steel frame residential building costs based on the Interpretive Structural Modeling(ISM)methodology.The system elucidates the interrelationships among these factors in a clear and intuitive manner.Concurrently,the Ideal Point Method was employed to compute the combined weights of each factor,thereby revealing the principal influencing factors.The research findings indicate that six factors,including the economic feasibility of steel component procurement and that of"Three-board"(referring to prefabricated wall,floor,and roof panels)element acquisition,exert substantial influence on the cost of prefabricated steel frame housing,hence being designated as critical elements for cost management.In order to effectuate effective cost control,according to analysis result,improvement recommendations were put forth in four domains,chief among them being the containment of expenses associated with steel components and"Three-board"elements,derived from the analytical outcomes.
