Abstract: Objective: As an essential component of new infrastructure, urban rail transit projects are characterized by their large construction scale, diverse disciplines, and data archiving difficulties in. Digital delivery, as a crucial part of construction project informatization, serves as a fundamental data carrier for digital twins and metaverse field, effectively addressing issues such as missing data, inaccurate information, and difficulties in retrieving operation period documents in conventional paperbased completion and delivery process. Through digital delivery based on BIM (building information modeling) technology, the project efficiency and enterprise informationoriented management can be improved, driving the modernization process of the construction industry.Method: Based on existing research on digital delivery, focusing on the urban rail transit industry, a systematic study is conducted on the implementation plan, delivery process, key technology solution schemes, and platform application of digital delivery application based on BIM technology. Key technical aspects that impact digital delivery including the implementation scope, modeling requirements, attribute information maintenance, component coding, and lightweight engine are examined through elaborative practices.Result & Conclusion: Through practical engineering project application, the feasibility of digital delivery in urban rail transit projects is verified. The characteristics and challenges of implementing BIMbased digital delivery are summarized, and corresponding optimization direction for technical solutions is proposed.
