BIM is an important technology to achieve full life cycle of green building, while decoration project is an indispensable part of achieving a full life cycle of green building.Therefore, it is significant to investigate the process of BIM application in decoration engineering. This paper first presents the researches on BIM application in the decoration engineering and the current practice. Then it analyzes features of the whole design and construction processes of traditional decoration engineering and application software. Based on the features of BIM technology application, the paper proposes the entire process workflow for BIM application in decoration engineering. It also makes a summary on the obstacles Revit-based BIM technology features, initially proposed decoration works in today's BIM technology application of the basic processes and summarizes the current project implementation process in the decorative application obstacles, to explore its application in decorative works seamlessly ideas, look to the future direction of development.
