The delay in civil construction works is observed globally and affects the economy of countries. Therefore, identifying the causes of delays is of paramount importance to minimize their consequences. This paper aims at identifying the causes of delay in construction works and their analysis and existing correlations through statistical factor analysis. The research methodology included a Systematic Literature Review (SLR), a Survey Research through questionnaires and interviews was conducted, as well as the identification of the main causes of delay through the Relative Importance Index (RIL) and the ABC Curve. Finally, factor analysis of the causes of delay was performed, not limiting only to their identification. The results showed that the 12 identified causes are correlated to 4 delay factors, which account for 69.18% of the sample variance: supply management (21.41%); workforce management (20,79%); project management (17.64%) and management of climatic conditions (9.34%). It is concluded hereby that the delay factors mentioned herein can be considered management deficiencies in the projects and that the research has expanded the knowledge on construction delays, thus contributing to the frontier of knowledge to mitigate this problem in several countries, especially developing ones.
The world experienced several economic, social and environmental transformations during the COVID-19 pandemic, and today, society assesses all these changes in the different stages of the pandemic process. In this sense, this research aimed to evaluate the educational and environmental impacts on the academic community of the largest educational institution in the Brazilian Amazon. The perception of the quality of teaching of undergraduate and graduate engineering students during remote teaching was assessed by means of an exploratory research work carried out at the Federal University of Pará (Brazil). Ecological and carbon footprint indicators were also measured through the Global Footprint Network®. In social terms, students pointed to a reduction in the quality of teaching. Despite the incentives through institutional initiatives for both students and professors, the community was not prepared to fully migrate to the virtual world, and that made the teaching–learning process difficult. In environmental terms, the reduction in the ecological footprint that was observed could have reached values higher than those that were found, to the order of 2.33%, with the mobility sector achieving the greatest reduction.
Trabalhadores que atuam na indústria da construção são expostos a diversos fatores estressantes, e realizam tarefas exigentes em ambientes de trabalho perigosos, afetando a saúde, a segurança e o bem-estar. O objetivo desta pesquisa é identificar os principais aspectos que estão sendo relacionados ao bem-estar no trabalho (BET) em profissionais do setor da construção. O método consiste na execução de uma Revisão Sistemática da Literatura (RSL) em 10 bases de dados internacionais. Um total de 93 publicações apontou 89 aspectos relacionados ao tema. Dentre os principais aspectos encontrados, 31% referem-se a medidas de BET e estresse, 19,8% a saúde física, 14,5% a segurança, 6,1% a saúde mental e 4,4% a aspectos gerais. Os achados desta pesquisa refletem razoavelmente a singularidade dos profissionais da indústria da construção e ratificam a necessidade de uma abordagem convergente a respeito do tema, que, certamente, poderia proporcionar práticas mais eficientes e objetivas de fomento ao bem-estar
