GeoBIM Implementation for the Development of Transmission Projects and Digital Twins for the Optimization of Substation Management in Operation

Environment (CDE) and integrated with corporate GIS systems.

The implementation is supported by structured technical requirements covering reality capture, georeferencing, “As-Is” modeling, parametrization, and information management. These requirements establish a consistent digital baseline that enables reliable representation of existing assets and supports the reuse of GeoBIM “As-Is” models as reference models for reinforcements, extensions, and modernization projects. This approach improves design coordination, reduces uncertainties in brownfield environments, and enhances data consistency across disciplines.

Within this context, the EletroBIM project represents a large-scale initiative aimed at the digitalization of transmission substations through GeoBIM. Reality capture technologies—such as terrestrial laser scanning, aerial photogrammetry, and GNSS surveys—are used to generate georeferenced point clouds, which are converted into parametric BIM models enriched with technical, operational, and regulatory information [1], [4], [10]. These models support engineering, documentation, and asset management activities throughout the project lifecycle.

The results demonstrate that the structured adoption of GeoBIM contributes to improved data reliability, design efficiency, and integration between engineering and operation. Furthermore, the implemented GeoBIM models provide a solid foundation for the future evolution toward

Digital Twin applications [12], [13], enabling the gradual incorporation of operational data, monitoring systems, and advanced analyses to support substation management.
