This article presents the development of an Augmented Reality (AR) application to assist in the assembly of a precast wood-frame wall, based on the BIM model of the wall execution sequence. The research study used the Design Science Research approach and its aim was to develop an AR application named "montAR" (version 2.0). This application offers a tutorial that combines a wall model visualized in AR in actual scale, followed by an audio with step-by-step instructions of the assembly process. Its applicability was simulated in a laboratory with the participation of volunteers (architecture and engineering students). Two visualization gadgets were used and compared: smartphones and smart glasses. The potentialities and difficulties of the use of the AR system were assessed through a questionnaire answered by the participants and through direct observation and result analysis by the researchers. The results demonstrated the potential of using AR for precast wall assembly. From a technological innovation perspective, this study emphasizes the potential use of AR as a technology suitable for training and for construction quality control.

Lina Bo Bardi’s Glass House (Casa de Vidro) is a National Historic Landmark designed and built in the late 1940s in São Paulo, Brazil. The house is one of the symbols of modern Brazilian mid-century architecture. It is a historiographical reference of the history of modern architecture in Brazil. This article reports the experience, outcomes, challenges, benefits, and limitations of the Heritage Building Information Modeling (HBIM) process. The HBIM was developed for Lina’s Glass House considering the following steps: modeling planning; data acquisition; model elaboration; recording of pathologies and damage; data management; documentation process. The HBIM developed includes historical information and geometric data from direct measurements, laser scanning, photographic survey, and pathologies documentation. The model allows professionals responsible for architecture, conservation, and restoration to access integrated information on projects and the current condition of the buildings easily and quickly. Good precision was achieved for important building elements, contributing to maintenance and restoration actions. This experience allowed the development of an integrated workflow of activities for collecting, processing, recording, and managing information that may serve as a baseline for future projects for the documentation of modernist buildings.

Um dos mais importantes documentos para a avaliação do estado de conservação do patrimônio cultural construído é o Mapa de Danos, cuja função é apresentar de forma sintética e precisa as informações referentes às anomalias identificadas nessas construções, assim como suas ações corretivas. No entanto, esse documento é usualmente produzido em sistemas de representação bidimensional, que não favorecem uma estruturação consistente dessas informações, tampouco a interoperabilidade. A Modelagem da Informação da Construção Histórica (HBIM) oferece novas possibilidades para o registro dos danos, uma vez que toda a documentação poderia ser associada a um banco de dados e atualizada ao longo do ciclo de vida das construções históricas. Portanto, essa pesquisa tem como objetivo principal apresentar os resultados qualitativos de uma Revisão Sistemática da Literatura (RSL), desenvolvida com a finalidade de identificar o estado-da-arte de pesquisas relevantes que correlacionam os conceitos de HBIM e Documentação de Danos do Patrimônio Construído. A pesquisa foi realizada em seis etapas: (1) Definição da Questão; (2) Estratégia de Busca; (3) Triagem e Elegibilidade; (4) Avaliação da Qualidade; (5) Síntese dos Resultados e (6) Apresentação do Estudo. Foram constatadas distintas finalidades para a documentação diagnóstica utilizando a metodologia HBIM, como avaliação estrutural e gestão de obras de restauro e conservação. Entretanto, foram ressaltadas dificuldades de interoperabilidade entre as ferramentas, que precisam ser aprimoradas de forma a possibilitar a comunicação e gestão das informações relacionadas ao Patrimônio Cultural Construído.

Built between 1911 and 1914 by architect Francisco Izidoro Monteiro, the former neoclassical building of the Belo Horizonte School of Medicine (BHSM) was located in a central area of the city. Its design, inspired by the European precepts at the time, was embedded in the same architectural language that characterized the cityscape of the capital of Minas Gerais, Brazil. The original building was gradually dismantled and completely demolished in 1960 to make way for the present headquarters. Few records of its existence remain. In order to contribute to the construction of the digital heritage of the old BHSM building, this article presents its virtual reconstruction, and demonstrates and analyzes the application of Heritage Building Information Modeling (HBIM) for this purpose. Based on data collection and the organization of numerous references (historical photographs, former students’ recollections, magazine articles, books, minutes, and photogrammetry of the remains), a hypothetical model of the building was developed to represent its condition as built and prior to demolition. Despite the difficulties in modeling, it was possible to perform a virtual historical reconstruction of the building, providing a better understanding of the building that does not currently exist. The preservation of the digital heritage of the demolished building aims to raise public awareness of its memory, which is consistent with the collection of the Memory Center of the UFMG School of Medicine (CEMEMOR).
