Fluxo de trabalho para o desenvolvimento de modelos BIM a partir de levantamentos tridimensionais: estudo de caso

Abstract

The Civil Engineering sector increasingly demands precision and efficiency, especially in the digital representation of existing buildings. In this context, the integration of Building Information Modeling (BIM) methodology with 3D Surveying technologies (such as Laser Scanning) emerges as the Scan-to-BIM solution, important for renovation, restoration, and asset management (Facility Management) projects. However, the direct conversion of point clouds into parametric BIM elements presents significant challenges related to interoperability, processing time, and ensuring the necessary Level of Development (LoD). This work proposed and detailed an optimized Scan-to-BIM workflow that minimizes bottlenecks and maximizes the accuracy of the final model. To this end, a review of work methodologies was carried out to map best practices and the most effective software in processing and modeling. The proposed workflow details everything from data acquisition in the field to the delivery of the BIM model, providing a practical and theoretically sound guide for professionals in the field. This study is expected to contribute to the standardization and improved quality of as-built BIM building models in the international context.
