Railway Station Engineering Information Classification And Coding Based On BIM Research

China’s railway construction has entered a high tide in recent years, as the railway construction, safety, quality, progress, investment, use maintenance put forward higher requirements, Construction phase of the BIM technology application is necessary. Railway construction project contains many professional, the application of BIM technology to construction management work, need to store large amount in the BIM model geometry information and geometry information. In determining the BIM model size and information content, we need for BIM components and contains information classify and coding. It can put the BIM model and information model organically together, realize information sharing, and for the different stages of construction projects, provide service of participants for various applications.BIM implementation of the basic work is Analysis the demand of the railway project BIM, the granularity of BIM information models, information content, information classification and coding. SO, it is helpful for that we better apply BIM technology, which have great significance of the railway construction.This article through the BIM technology application in railway construction project are analyzed the construction of the information.which is needed in various applications,and all kinds of information classify and coding, how to use the codecompleteconstruction management tasksPut forward the solutions. Based on the information classification and coding,it set upall kinds of information in different stages of project, and establishthe connection between the different contractors, BIM for data sharing in different applications has building foundation, to the popularization and application of BIM technology in railway construction project have great significance.
