T/XJBX 0168-2025 Digital Engineering Archive Management and Storage Technical Specifications

Scope

Construction activities are characterized by long cycles, multiple participants, detailed professional division of labor, and complex types of outcomes. The resulting project archives serve as important evidence for project quality, safety, and compliance, as well as key data assets for the entire lifecycle of facility operation and maintenance, expansion and renovation, asset management, and risk tracing. With the advancement of digital transformation in engineering, the carriers of project archives have shifted from primarily paper-based to multiple types such as "electronic documents, images, model data, monitoring data, and system logs". The methods of archives formation and transfer have transitioned from offline collection to online collaboration, and the utilization of archives has evolved from manual retrieval to cross-system search and data reuse. Against this backdrop, project archives management faces practical challenges including scattered data sources, inconsistent formats, missing metadata, version confusion, insufficient storage reliability, long-term readability risks, unclear permission boundaries, and increasing security and compliance requirements. This document addresses the entire process of "digital project archives" from formation, collection, organization, filing, storage, preservation to utilization and migration, proposing technical requirements for management and storage. It emphasizes standardized metadata as the core, ensuring the integrity of the evidence chain as the bottom line, targeting long-term availability, and constrained by security and compliance, aiming to achieve "receivability, manageability, searchability, usability, migrability, and provability" of project archives. This document is applicable to construction units, survey and design units, construction units, supervision units, testing units, operation and maintenance units, and third-party archives service institutions in building digital project archives management a
