Abstract: With the emergence of BIM (Building Information Model) technology, the second digital revolution in the construction industry arrives, symbolizing the continuous development and recognition of BIM technology in the whole industry. The decoration engineering is an important part of the whole life cycle of buildings, and it is also a trend to improve the experience of the householder and the quality of the project. This paper takes the apartment type of standard floor in double tower of the Dream Building in South Korea as an example, to explore the standard process and application of BIM in the indoor hardcover engineering. A high precision 3D model is built to achieve a comprehensive, multi angle, information-based model effect display of the project, and to further prospect its future application direction.
