A reabilitação de edifícios é uma prática diferente de novas obras, envolvendo a caracterização prévia dos elementos existentes e do seu estado das condições de conservação. Toda a recolha de dados existente, a análise de projetos e o gerenciamento de projetos podem estar em uma dimensão em que o manuseio não digital é um fator de dificuldade para o projeto como um todo. Isso pode contribuir para a perda de dados importantes relacionados com aspectos técnicos e com a gestão de decisões das partes interessadas. As tecnologias Building Information Modeling (BIM) são conhecidas por serem uma excelente opção para lidar com informações de novos projetos. No entanto, seu uso e potencial em trabalhos de reabilitação, em geral, permanecem desconhecidos ou não utilizados por várias razões.
O principal objetivo desta pesquisa é determinar, usando a ferramenta de análise SWOT, as várias fases dos projetos de reabilitação de edifícios conectados ao potencial do BIM. Além disso, espera-se determinar se essa tecnologia é uma solução viável para esses casos e quais são as restrições envolvidas. Por meio de recolha de dados em fase de projeto e entrevistas após a pesquisa e análise BIM, foram efetuados três casos de estudo. Paralelamente à análise do BIM, a metodologia SWOT foi aplicada com o objetivo de entender as vantagens, restrições e também identificar as oportunidades.
A metodologia BIM foi aplicada aosprojetos estudados nas dimensões 3D e 4D. A análise 3D teve como objetivo detectar incompatibilidades entre as diversas disciplinas dos projetos e informações relacionadas aos elementos existentes. Já a análise 4D consistiu em associar todos os elementos construtivos de acordo com o plano de trabalhos e analisar o comportamento de sequenciamento da construção.
A utlização de BIM veio demonstrar nos casos de estudo aplicados, que é possível determinar maior número de falhas e de erros em fase de projecto, eliminando as mesmas da fase de obra, o que se traduz numa melhor gestão da obra, em termos de prazos, gestão de recursos, de mão de obra e aumento da qualidade.
The retrofitting works of buildings are a different practice of the new construction works, involving the previous characterization of the existing elements and their conservation conditions. All existing data collection, project analysis and project management might be in a dimension where non-digital handling is a difficulty factor for the project. That could contribute losing important data related to technical support and for stakeholder’s decision. The Building Information Modelling (BIM) technologies are known to be an excellent choice handling information for new projects. However, its usage and potential in retrofitting works may remain unknown or not utilized for several reasons. The main goal of this research is to determine, using SWOT analysis tool, in the various phases of building retrofitting projects, the potential of BIM. In addition, it is expected to determine whether this technology is a feasible solution for these cases and what are the constraints involved. Through data collection in design phase and interviews after the research and BIM analysis, were used in three different design retrofitting works. At the same time of the BIM analysis, SWOT methodology was applied aiming to understand the reasoning, constraints and also to identify opportunities. The BIM methodology was applied to three design projects studied in 3D and 4D spheres. The 3D analysis aimed to detect incompatibilities among the various disciplines of the projects and information related to the existing elements. The 4D analysis consisted in associating all the building elements with the construction scheduling plan in order to analyse the activities sequencing behaviour. The use of BIM has shown in the case studies that it is possible to determine the largest number of failures and errors in the project phase, eliminating them as they are in the project phase, or translating into better project management in terms of time, resource management, labor and quality enhancement.
