The pipeline network layout in the terminal land area is extensive,with a wide variety of pipeline types.Moreover,as a hidden project,the pipelines are difficult to maintain and inspect later on.This paper proposes the use of building information modeling (BIM)+augmented reality (AR) technology to enhance the reliability of the design scheme and improve the precision of pipeline layout.At the same time,it aims to accumulate data assets to lay a foundation for later digital operation and maintenance.Due to its three-dimensional visualization advantages,BIM technology can play a significant role in pipeline network design.BIM+AR technology can further conduct on-site layout of pipeline design results,thus expanding the application value of BIM technology.However,the application practice of BIM+AR technology in the pipeline network of the terminal yard is currently limited.This paper presents the implementation steps and application methods of BIM+AR technology in the pipeline network integration of the terminal yard and verifies them through phaseⅠcontainer terminal renovation project in Luojing port area of Shanghai Port.The results show that BIM+AR technology can be used for scheme optimization and briefing,construction progress,quality and safety management,guiding the construction of complex nodes,and serving later operation and maintenance.The technology is replicable and can be promoted.
