Heritage buildings are of great importance to the human perception of the culture of a community. HBIM (Historic Building Information Modelling) tools offer a possibility of an improved data set of information related especially to the restoration and preservation of historical buildings. This work aims to assess the damage of a historic house by means of integrated HBIM tolls and experimental procedure. 3D modelling with REVIT, 3D modelling with point cloud data and visual inspection of the historic house were performed. The comparison between the two 3D modelling techniques showed a level of damage consisting of a difference between the levels of the roofs. In addition, the visual inspection detected presence of cracks in the walls which agrees with the damage observed from the 3D models comparison. Results indicate that HBIM tools significantly contribute to damage assessment in heritage constructions.

A estabilidade de estruturas é fator essencial para as atividades desenvolvidas pela engenharia civil e estão diretamente relacionadas ao comportamento do solo sobre o qual se encontra. Todavia, não se pode utilizar conceitos voltados a materiais homogêneos e bem definidos em análises do solo, uma vez que esses possuem estruturas heterogênea e descontínuas impedindo a aplicação de conceitos da mecânica do sólidos. Assim, percebe-se a importância da compatibilidade entre o esforço aplicado pela infraestrutura de uma edificação no solo com a resistência do terreno. Embora os estudos geotécnicos garantam uma certa segurança às obras, a ocorrência de acidentes não previstos durante o desenvolvimento do projeto podem vir a prejudicar o desempenho das construções com a presença de manifestações patológicas. Dessa forma, o presente artigo objetiva a investigar, apresentar e avaliar incidentes que interferem no desempenho da interação solo-estrutura e na sequência, caracterizar a distribuição das tensões. Para isso, realizou-se análises numéricas através do Métodos dos Elementos Finito (MEF) possibilitando a visualização de esforços provenientes de eventos como recalques diferenciais em uma construção advindos da redução do desempenho do solo em conjunto com as estruturas de fundação. Assim sendo, o trabalho encontrou resultados que demonstram comportamento característicos e de grande importância para o entendimento do surgimento de danos, especialmente fissuras, além de apresentar uma ferramenta eficiente de modelagem e análise facilitando a compreensão de eventos imprevistos.
