T/XJBX 0141-2025 Highway BIM Digital Application Specification

Scope

Highways projects are characterized by large investment scale, multiple participating units, strong interdisciplinary collaboration, long construction periods, and high requirements for operation and maintenance. The traditional information management approach dominated by two-dimensional drawings and scattered documents is prone to information disconnects and version conflicts in multi-disciplinary collaboration involving route planning, roadbed and pavement construction, bridges and culverts, tunnels, traffic and electrical safety, and environmental protection and landscape design. This results in insufficient transmission of design intentions, inadequate control of construction processes, incomplete basis for change and claim settlements, unclosed quality and safety traceability chains, and missing asset data in the operation and maintenance phase. The integrated application of BIM (Building Information Modeling) and digital technologies enables the use of information models as a unified data carrier to achieve continuous management of project information from survey and design to construction, acceptance, and operation. This enhances collaboration efficiency, process transparency, risk early warning capabilities, and asset management levels. Transportation authorities have issued industry standards for the application of BIM in highway projects, clarifying model requirements, application and delivery processes, providing a unified foundation for BIM application in highway engineering. Meanwhile, international standards such as ISO 19650 series propose a common framework for BIM-based information management, which can serve as a reference for digital information organization, delivery, and safety management in highway projects. Against this backdrop, it is necessary to align with the full life cycle management needs of highway projects to develop feasible, verifiable, and deliverable BIM digital application standards, unifying implementation planning, mo
