Research on construction technology of BIM data exchange service based on SaaS

Data exchange during BIM application has become a critical bottleneck constraining information sharing and collaborative work. To address issues such as software silos, inconsistent data standards, and insufficient cross-platform interoperability, this study proposes and implements a SaaS-based BIM data exchange service platform. The research focuses on API interface integration and data services, transmission protocol optimization, data model converters, data template development and management, and engineering data dictionary creation and maintenance. A comprehensive data exchange workflow covering requirement definition, model conversion, exchange execution, and process monitoring has been constructed. Results demonstrate that the platform not only supports incremental updates and semantic completeness of BIM models but also enhances data reusability and delivery quality through data templates, data dictionaries, and automated mapping mechanisms. The research findings provide a feasible technical pathway for promoting standardized, normalized, and intelligent exchange of BIM data.
