Abstract:

The visualization characteristics of building information modeling(BIM) technology is fully used to solve the discreteness problem of information in the construction schedule management of Beijing Metro Line No. 19, and ensure the orderly integration of various construction information with the construction logic. The construction schedule management based on BIM in Ping′anli Station on Beijing Metro Line No. 19 is analyzed. Firstly, the logic of BIM schedule management is determined, and the partition mode of BIM model and the additional information behavior in the process of model establishment are described through modeling to ensure the accuracy and validity of model schedule tracking. And then, the information addition, tracking and integration are further improved through the development of information platform. Finally, the new means of adding, tracking and integrating process information, material information and cost information in the construction process by BIM technology are explored, and the conclusion that BIM technology can effectively comply with the construction logic to add, track and integrate construction process information is drawn. Its advantages are mainly embodied in visual information transmission, information tracking and integration.
