Building Information Modeling (BIM) para gestão da segurança do trabalho em obras de habitações populares

 Civil construction has peculiar characteristics such as low communication between the designers and the site managers, in addition to a high turnover of construction workers, which creates difficulties to implement an effective safety culture. The emergence of technologies has contributed to the improvement of communication and security, an example is Building Information Modeling (BIM) that allows the computational modeling of the work, which provides detailed data of its progress even in the design phase. This research aims to model a vertical work of social interest. The modeling was based on the standards defined by NR 18. After the modeling was completed, the results were compared with the real scenario of the construction, aiming to assess incompatibilities with what is required by NR. For modeling, the software Revit, MS Project, and Naviswork were used. It was concluded that the work did not meet some aspects required by NR, in addition to a lack of projects, design errors, and execution problems. As for the site managers, it was evaluated that the use of BIM in their construction sites could bring benefits to their work and facilitate decision making.A construção civil possui características peculiares, como baixa comunicação entre os projetistas e os responsáveis técnicos pela execução da obra, além de grande rotatividade de operários, o que gera dificuldades para implantação de uma cultura de segurança eficaz. O surgimento de tecnologias vem contribuindo para a melhoria da comunicação e segurança, um exemplo é o Building Information Modeling (BIM), que possibilita a modelagem computacional da obra, que oferece dados detalhados do seu andamento ainda na fase de projeto. Esta pesquisa objetiva realizar a modelagem de uma obra vertical de interesse social. A modelagem baseou-se nos padrões estabelecidos pela NR 18. Finalizada a modelagem, os resultados foram confrontados com o cenário real da obra objetivando avaliar incompatibilidades com o que se é exigido pela NR. Para a modelagem utilizou-se os softwares Revit, MS Project e Naviswork. Concluiu-se que a obra não atendia alguns aspectos exigidos pela NR, além de falta de projetos, erros de dimensionamento e problemas de execução. Quanto aos responsáveis técnicos pela obra, foi avaliado que o uso do BIM em sua obra poderia trazer benefícios para o seu trabalho e facilitar a tomada de decisões

Construction delays: a case study in the Brazilian Amazon

The construction industry is one of the industrial sectors with the lowest rates of fulfilment of contract deadlines, especially in developing countries. This fact has been the focus of considerable discussions seeking to identify the causes of the delays. The main purpose of this paper is to use factor analysis to identify the factors that are correlated with delay, contemplating exclusively residential real estate projects and using a city in the Brazilian Amazon as a case study. Based on the database from the government agency that authorises constructions in the city of Belém (City Planning Department – Secretaria Municipal de Urbanismo, SEURB) and data from construction companies, the study investigated 274 construction projects from the past 11 years. Factor analysis and work with the variables that can be identified and measured in the initial phase of the project, i.e., during the feasibility study, demonstrate that the physical characteristics of the apartments and the construction project are the primary causes for variations in construction delays; these causes have not yet been reported in the literature. We hope that the results of this study will contribute to more consistent forecasting of construction time, minimising the risk of delays
