The invention discloses a substation construction complete period digitized management and control system based on a BIM. The system comprises a substation three-dimensional model and a cooperative management platform, and the cooperative management platform comprises a data input module, a data collection module, a database, a 3DGIS+BIM platform, an interactive module and a comprehensive application module; the data input module is used for inputting input-type data for substation construction; the data collection module is used for collecting collection-type data for the substation construction; the 3DGIS+BIM platform uses all kinds of data stored in the database to construct the substation three-dimensional model; the interactive module achieves information interaction and instruction interaction with the 3DGIS+BIM platform; the 3DGIS+BIM platform calls the comprehensive application module to conduct corresponding operation according to a control instruction. In this way, reliable and accurate control over the entire substation construction process and management of the entire substation construction process are achieved.
