In view of the problems of short construction period,insufficient design depth,multidisciplinary crossing and frequent quality defects in the railway electric/electronic systems engineering construction,BIM is introduced to support construction management,which makes it possible to detect and solve such problems in advance,avoid reprocessing and material waste,and improve quality and economic benefit.This paper discusses technology features of BIM,analyses status of BIM adoption,proposes such BIM systematic application solutions in railway electric/electronic systems engineering construction period as establishment of BIM application organization,integration and deployment of software/hardware,and creation of BIM application standards.This paper studies BIM-based professional applications,including parametric modeling approach of overhead contact line,pre-calculation of cantilever,optimization of mistake/omission/conflict/missing,engineering material statistics,and cable layout optimization.The paper also studies BIM-based integrated management applications,including information management of catenary pole,progress and inventory management.The application of BIM technology can intuitively reflect the construction process,enhance data sharing,timely detect errors and omissions among various majors,reduce re-work,improve work efficiency and quality,and shorten construction period.This study provides valuable experience for BIM application in railway electric/electronic systems engineering construction.
