Abstract:
Building Information Modeling (BIM) is the second technology revolution of the application of information technology, and it has become an inevitable trend in the informatization of construction industry and high-efficiency application management. Urban rail transit involves various professions, and the communication and coordination between these professions could be difficult. In this paper, management based on spatial visualization using BIM was applied in domain of urban rail transit development. The application of BIM started from five stages, which were preparation of project, modeling for different stages and professions, model integration, application in construction, and collection of feedback information in the late period. BIM technology was used in the basic applications such as three-dimensional instruction, construction simulation, construction application, guarantee of progress, control of cost, supportive management of safety and quality and so on. Furthermore, it was exploited in applications such as analysis of energy conservation, assistance in modification of pipeline and simulation of emergency evacuation. Based on the mentioned applications, BIM technology was utilized throughout the subway construction period. BIM technology helps to achieve the informatization management of subway construction project and creates construction sites with intelligence and civilization.
