O setor da Construção Civil possui participação significativa na economia brasileira, estando diretamente ligado ao desenvolvimento e produção nacional do país. A participação do setor representou 5,3% da economia nacional nos últimos anos, com forte influência na geração de empregos. Além de políticas habitacionais e obras de infraestrutura, os megaeventos esportivos também impulsionaram o crescimento do setor. Contudo, os problemas da gestão ineficaz nas ações governamentais para realização desses eventos desencadearam na recente crise econômica e subsequente retração do setor da construção civil. O presente trabalho tem como objetivo analisar os reflexos da atual crise econômica no mercado da construção civil brasileira, iniciada em 2014. A partir das análises estatísticas foi possível avaliar o comportamento do setor bem como a relação entre os indicadores econômicos e os da construção civil. O tema possui relevância para todos os interessados no setor da construção civil que buscam informações verídicas e confiáveis. Os resultados obtidos indicam correlação forte entre o PIB do Brasil e o PIB da Construção Civil, bem como influência na taxa de desemprego. O setor da construção civil encontra-se em lenta recuperação, seguindo em paralelo com a recuperação econômica do país, sendo o setor que mais sofreu impacto da crise e apresentou uma retração de 32,6% nos últimos seis anos.
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.
In a context of expansion and densification of cities, themes related to mobility and the improvement of the quality of life have aroused the interest of researchers and county managers. Using the case of the main urban mobility intervention in Niterói, the TransOceânica Road Corridor (CVT), this work aims to identify the perception of the population affected by the project in relation to the occurrence of the impacts predicted in the project planning phase, as well as to identify which of these impacts most influenced the standard of living and mobility of this population. The survey results showed that the respondents’ perception of the impacts—as the change of air quality, the change of noise levels, the alteration of the local dynamics and neighborhood disturbance—did not confirm the scenario envisaged when planning the project.
