Research on Key Technologies of Railway Electric and Electronic Systems Engineering Construction Management based on BIM

In view of the problems of short construction period, insufficient design depth, multi-disciplinary cross and frequent construction quality problem in the railway electric/electronic systems engineering construction, introducing BIM(Building Information Modeling) to support construction management is able to detect and solve problems in advance, avoid reprocessing and material waste, enhance the quality and economic performance. This paper discusses technology feature of BIM, analyses status of BIM adoption, proposes BIM systematic application solution in railway electric/electronic systems engineering construction period, including building BIM application organization, integration and deployment of software/hardware, BIM application standards. This paper studies BIM-based professional applications including parametric modeling approach of overhead contact line, pre-calculation of catenary wrist arm, mistake/omission /conflict/missing optimization, engineering material statistics, cables layout optimization. Also studies BIM-based integrated management applications including information management of catenary mast, progress management and inventory management. By adopting BIM technology, the application can intuitively reflect the construction process, enhance data sharing and timely detect the errors and omissions among various majors, leading to reduce re-work, improve building efficiency and quality. This study provides valuable experience for BIM application in railway electric/electronic systems engineering construction.
