The present invention relates to a 3D BIM object modeling server for implementing 3D modeling by using BIM information and GIS information, and a 3D BIM object modeling system including the same. According to an embodiment of the present invention, the 3D BIM object modeling server comprises: a server communication unit performing a function of interworking with a user terminal via a wired or wireless communication network; a server storage unit storing GIS data which integrate BIM data for virtually modeling a building, geographic data occupying a spatial location, and attribute data related to the geographic data; and a server control unit transmitting primary modeling data to the user terminal in response to a primary request transmitted from the user terminal, and transmitting, to the user terminal, secondary modeling data about a specific object when a secondary request for the at least one specific object is transmitted from the user terminal having received the primary modeling data. The present invention can improve user convenience.
