Combined with Large-scale Commercial Complex and Metro Integration Project of Beijing Changping Future Science and Technology City, this paper explores how to apply BIM technology to improve the efficiency of engineering, such as integration structure optimization, process interspersing, multi-plot field coordination, quality safety, and business work coordination. Also, this paper explores the ways and possibilities of the integration of BIM standards in parks planning. According to the project′s emphasis and difficulties. BIM planning is carried out effectively in advance, combined with scientific and technological innovation, process simulation, 3D laser scanning, 3D printing, virtual roaming, software development, and other BIM technologies, comprehensive application modeling developing is achieved, engineering management and performance quality are improved effectively. This research provides a reference for the formation of smart park.
