Research On Real Estate Cost Control During Design Phases Based On BIM

Since 2010, the government has strengthened the regulation on real estate market, through a series of policies such as the “credit limit, the purchase restrictions and the price ceiling ", which is known as the most stringent regulation in history. Due to the dual pressure of declining sales and increasing development costs,the profit margin of Real Estate Development Enterprise has been close to 10%, which is the red warning line of the whole industry. In such a tough market situation,the real estate development enterprises not only want to survivethe hard time but also to go forward continuously.How toreduce expenditurebecomes an important issue on the condition of limited "open up source".By the method of literature research,expert interviews and questionnaires, this thesis has studied the cost control in design stage based on BIM technology, which is used to check construction drawing collisions, optimize the spatial structure,integrate mechanical and electrical engineering wiring and designthe parametric of the curtain wall. It not only reduces frequent changes during construction, but also implements feed-forward controlling of construction cost in the design stage, which effectively reduces the unreasonable investment and invalid cost, and ensures the real estate enterprises obtaining great cost advantages as well as laying the foundation for the future development in a fiercely competitive market, especially in such a downturn economic environment.
