Exploração e reflexões sobre o processo de documentação as-built, com uso de BIM e nuvem de pontos aplicadas em edificações

Abstract

In recent years, the adoption of Building Information Modeling (BIM) technology has been gaining ground in the architecture, engineering, construction and operations (AECO) sector. This is a result of the numerous advantages that this technology offers at different stages of the building life cycle, such as assisting in the recording of reliable data and enabling collaboration on projects. Despite these advances, it is still common for traditional approaches to project delivery to not provide complete documentation at the end of construction, or for operational activities, such as data collection, to involve the manual transfer of the information obtained. This can lead to an increase in the duration of on-site surveys, as well as a greater propensity for errors between the transfer of measurements and the interpretation of the information obtained. Some research has explored 3D scanning techniques and the use of BIM for as-built documentation, demonstrating that it is essential for end users and other stakeholders in construction. However, it is still a subject little explored in the literature. The objective of this work is to propose guidelines to optimize the as-built documentation work process using BIM and point clouds. As a framework for the development of the work, the methodology adopted is Design Science Research (DSR), as it aims to create an artifact to solve a real problem. The research uses bibliographical research to identify the main problems throughout the workflow, in addition to practical application through case studies, throughout the as-built documentation phases.
