| description |
Industrial production – the automatic cutting and bending – of rebar for reinforced concrete structures represents an improvement when compared to the traditional production method, wherein reinforcing bars were processed at the construction site. Nevertheless, the efficiency of this process requires synergy among supply chain stakeholders. Problems related to the poor reliability of rebar's detailing drawings and orders affect the industrialized process efficiency. The design information is usually provided through paper-based documents and must be transcribed manually by the manufacturer before fabrication. Notwithstanding, some solutions that enable digital exchange and data reuse of the reinforcement by the fabricator are available. Besides, it is considered that BIM potentially contributes to mitigating problems related to the design quality. In this paper, the digital design-fabrication interface of cut and bent rebar is analyzed, alongside with the use of the BIM in the reinforcing detailing. Through a survey with rebar's fabricators and BIM software providers, the main standards used in the rebar data exchange and the BIM authoring tools that support this feature were identified. It was found that despite the rebar cutting and bending equipment, production planning management systems and BIM tools already support the rebar digital fabrication, this practice is still not established by the Brazilian market leading to the occurrence of automation islands linked by manual data transfer. |

Industrial production – the automatic cutting and bending – of rebar for reinforced concrete structures represents an improvement when compared to the traditional production method, wherein reinforcing bars were processed at the construction site.

A industrialização do processo de corte e dobra de aço para estruturas de concreto armado representa uma evolução em comparação ao método tradicional de produção de armaduras, em que o aço é processado no canteiro de obras. Entretanto, a eficiência desse processo demanda sinergia entre os agentes que atuam em sua cadeia produtiva. Problemas relacionados à qualidade do Projeto de Detalhamento de Armadura (PDA) e imprecisão nos pedidos podem comprometer a confiabilidade do processo industrializado. As informações contidas no PDA, usualmente fornecidas por meio de documentos impressos, precisam ser transcritas manualmente pelo fabricante antes do início da produção. Não obstante, encontram-se disponíveis soluções que viabilizam a transferência digital dos dados contidos no PDA e o reuso dessas informações na etapa de fabricação. Ademais, acredita-se que o emprego do processo BIM na elaboração dos projetos contribua para mitigar os problemas relacionados à qualidade do PDA. Este trabalho tem como objetivo analisar a interface digital entre o projeto e a produção industrial de aço cortado e dobrado e o uso do processo BIM no desenvolvimento do PDA. Mediante consulta a prestadoras de serviço de corte e dobra e representantes de software BIM, foram identificados os principais padrões utilizados no intercâmbio de dados e ferramentas de autoria BIM que suportam sua exportação. Identificou-se que, apesar dos equipamentos, sistemas de gestão utilizados pelas centrais de corte e dobra e ferramentas BIM possuírem suporte à interface digital, esta prática ainda não é adotada pelo mercado brasileiro, caracterizando-se por ilhas de automação ligadas por transferência manual de dados.
