Análise do projeto de reforma de um estabelecimento assistencial de saúde utilizando a captura da realidade e o BIM

Abstract

Documents management of the built environment, when effectively implemented, allows secure access to information. In Brazil, some governmental institutions have promoted the safeguard of the architectural design of their buildings, however, in some situations, this process is not efficient and requires reverse engineering efforts to recover missing technical information in order to enable the development of news designs. This study aims to analyze the retrofit design of a Health Care Establishment (EAS), using the BIM/VDC assisted by 3D Laser Scanning and Thermographic techniques, applying the Constructive Research method. To support the study, the architectural parametric modeling of the existing building and its surroundings was initially developed, based on point cloud data generated by the captured reality, since the EAS did not have any of its original building designs. The As-is BIM model included the operational phase of the built environment, mapping the areas of EAS that would be most affected by the implementation of the proposed retrofit design. Subsequently, design simulations in the virtual environment were used to help define the modeling work scope for the retrofit design and also to support the site technical inspection. The data collected on site provided the informations needed to analyze the results of the following stages, connecting the built environment and the BIM system. In the first stage, the CAD files of the retrofit design were used as inputs for the modeling software, generating the architectural and foundation models. Then, they were exported in open format Industry Foundation Classes (IFC), to the compatibility software Solibri Model Checker (SMC), in which they were previously validated aiming the qualitative control of the informations. In the third stage, automated compatibility between the models was promoted. The construct of this research established a new line of work in the application of the concept architecture design. Moreover, it demonstrated the feasibility of using the applied technologies, even in the initial phases of the design, adding a real value gain in the work process.
