Da evolução do LOD ao LOIN: aplicação dos requisitos de informação do caderno BIM Paraná (2023) sob a perspectiva da ISSO 19650

Abstract

The advancement of Building Information Modeling (BIM) has been changing how the construction industry organizes and shares information throughout project development. This study examines how the concept of Level of Development (LOD) evolves into the Level of Information Need (LOIN), aiming to analyze how information management, aligned with the intended use of the model, influences BIM-based project deliverables. The research is grounded in the ISO 19650 standard, which establishes principles for structuring and managing information, and discusses how clearly defining information requirements contributes to more effective communication and more consistent results. The case study focuses on the BIM Paraná Guide (2023), a public document that applies the LOIN concept and the information requirements OIR, AIR, PIR, and EIR in practice, highlighting the PIR for concentrating the essential information needed for model development. The analysis covered elements such as walls, doors, columns, and conduits to discuss the level of information required according to project needs. The findings indicate that the BIM Paraná Guide effectively structures the definition of information requirements from a LOIN perspective, providing a foundation and offering flexibility for clients to adjust information needs according to their demands. It can be concluded that LOIN supports clearer and more efficient deliverables, aligned with information needs in BIM environments.
