Construction project information system management framework strategy based on version control and collaboration

Modern construction projects widely rely on digital systems such as Building Information Modeling (BIM), Common Data Environments (CDEs), and cloud-based collaboration platforms to manage complex information workflows. While these tools support basic data exchange and model coordination, they lack structured mechanisms for fine-grained version control, asynchronous change auditing, and traceable multi-role collaboration. As a result, issues such as version confusion, delayed approvals, and fragmented workflows frequently arise. To address these limitations, this study proposes a version-controlled and role-driven information management strategy that introduces an active request–review–merge loop, a trunk–branch–freeze versioning protocol, and lifecycle-based traceability tagging. By integrating standardized information generation, version tracking, change auditing, and feedback-driven collaboration mechanisms, the proposed framework systematically addresses information fragmentation and coordination challenges. A scenario-based simulation and expert Delphi evaluation were conducted to assess the strategy's effectiveness. Results demonstrate significant improvements in version traceability (94.3%), collaboration response time (3.8 h), and information flow integrity (96.5%), outperforming traditional methods. This research establishes a lightweight, role-driven collaboration governance model, offering a theoretically grounded and practically viable approach to enhance construction information systems.
