The 3D model based on BIM technology of digital information can calculate quantities automatically by graphical representation and provides forceful support for electric power engineering cost intuitively. With the aid of Revit platform, this paper has a very good analysis on the difference between the rules of Revit software to calculate the amount and the rules of fixed quantity calculation, which is based on BIM technology and combines the rules of Electric Power Engineering Construction Quotas of 2013. At last, the modeling process and requirements are improved and quantities are calculated automatically by the rules of electricity quota engineering calculation.
