Abstract: Xi′an Maike Commercial Center is the first all-steel complex in the northwest area. BIM design, construction, operation and maintenance are integrated throughout the project life cycle. BIM technology is applied as early as in the design phase, and in addition to the basic design of the pipeline, the comprehensive arrangement optimizes the clear height, and also involves all aspects of hanger design, visualization correspondent, construction simulation, construction management and pre-processing factory. As a carrier, the project uses three-dimensional collaborative mode, and implements the BIM technology in the project, which greatly improves the construction quality, facilitates construction management, shortens the construction period, and lays a solid foundation for the operation and maintenance management of later stages.
