4.0 technology has now become the main focus of discussions around the world, looking for alternatives to improve productive performance and reduce costs using cutting-edge technology such as the internet of things, cloud computing, BIM ( Building Information Modeling), Machine learning and Big Date. In this context, the main objective of this article is initially to show what is industry 4.0 and the revolutions that preceded it, how it works in the Brazilian construction sector, the main advantages and disadvantages of using new technology in construction sites, such as will affect the worker and what are the challenges for deployment in Brazil. Given this, the article is characterized as an applied research, considered a basic research, and its approach is qualitative and quantitative, with the exploratory and descriptive objective. Thus, an online questionnaire was formulated for professionals, so the target audience was around 30 professionals, but only 18 respondents completed the submission of information, totaling the participation of 60% of professionals in the area, in order to To gather their opinion about the use of industry 4.0 in Brazilian civil construction, it is observed that most professionals work in the academic and business sectors. The survey results were compared with the current situation of the construction industry.

Equipment failure and production shortfalls can cause significant impacts on companies. Preventive maintenance can potentially increase equipment reliability and availability, helping companies achieve their corporate goals while reducing operation and maintenance costs. However, determining the optimal interval between maintenance interventions involves balancing various factors such as maintenance costs, equipment availability, risk of failures, and the need for corrective maintenance, as well as potential operational and financial impacts. Under this context, this paper aims to define the interval between preventive maintenance interventions for a key production equipment in a steel company located in Southeast region of Brazil. Upon documental analysis and interviews with experts, an AHP was applied to hierarchize the maintenance periodicity, based on the following criteria: part replacement based on service life, downtime hours for preventive maintenance, equipment reliability, and cost of materials and labour. A biweekly preventive maintenance periodicity was identified as the most adequate for the analysed device. An implementation plan was approved and preliminary results indicate no availability deterioration, while maintenance costs are below historical average.

A manufatura se constitui de um natural espaço gerador de riscos, sujeito à ocorrência de problemas de diversas naturezas, tais como falha humana, indisponibilidade de equipamentos, problemas com fornecedores entre outros. O inesperado, ou pelo menos o não planejado, ocorre e, de alguma forma, deve ser gerenciado. Os problemas que os gestores buscam solucionar hoje foram, em algum momento, riscos que não foram prevenidos no passado, ou seja, riscos que foram ignorados. Dessa forma, medidas preventivas para não permitir que os riscos se tornem problemas são fatores condicionantes para a perpetuação de uma organização. Como solução, ou pelo menos minimização dos efeitos indesejados oriundos desses problemas, diversos pesquisadores recomendam a adoção da Flexibilidade de Manufatura. Entretanto, sua característica multidimensional e as particularidades de cada empresa, dificultam o correto estabelecimento do grau de flexibilidade com base nas variáveis existentes, ou seja, em quais tipos de flexibilidade uma organização deve investir para minimizar seus riscos. Diante de tal situação, realizou-se uma pesquisa empírica em uma indústria química, baseado em levantamento da percepção dos funcionários de nível gerencial do departamento de produção, onde foram analisados os principais problemas que afetam seu ambiente operacional e os tipos de flexibilidades mais requeridos por essa empresa para a solução de seus problemas. Como achado da pesquisa, observa-se que, apesar da vasta tipologia de flexibilidades de manufatura, apenas quatro tipos são seguramente demandados pela empresa estudada: mão-de-obra, mix, produção e volume. Tal achado permite à organização pesquisada priorizar seus investimentos em flexibilidade, de forma a minimizar/solucionar seus problemas produtivos.
