Abstract：
The construction stage is the main stage of cost and resource consumption, and the cost of controlling the stage is the key content of the construction industry to improve efficiency and increase profits. There are many problems in the control of construction stage in our country. From the technical level and management level analysis, and foreign engineering cost construction stage management has a larger gap. By combining the traditional engineering cost with the modern information technology, it can reduce the building energy consumption, rational use of resources and construction cost, in which BIM technology has become a key link in the construction of information technology.
