Análise da duração das atividades construtivas de duas subestações de energia Elétrica em Pernambuco estudo de caso

Abstract

Although the acceptance of electricity was quite rapid in the 19th century, in the 21st century in Brazil thousands of people found themselves without access to electricity. In order to solve this problem, the federal government created the social program “Luz Para Todos” (Light for All), with the aim of bringing electricity to rural regions and/or to homes that did not yet have it. Several investments were and still are being made in energy generation, the construction of transmission lines and substations to guarantee the arrival of energy. Substations act as delivery points for energy to consumers. Although substations are basically an electrical installation, their construction requires a lot of civilian labor. In view of the importance of substations, this paper aims to analyze the physical schedule of two substations located in the municipalities of Tacaratu and Goiana (Tejucupapo) in Pernambuco, through the precedence activities, analyze the time of each work through the resource duration table, and analyze the analytical project structure. A well-executed physical construction schedule helps to verify the need for materials, labor and equipment. It is an instrument that allows stages to be adjusted to recover downtime, avoiding delays in delivery. According to the results obtained in this study, the Tacaratu substation had a longer duration than the one analyzed in the resource duration table, while the Tejucupapo substation went in the opposite direction, with a shorter duration than the one studied in the resource duration table, one of the possible causes being the logistics of materials between the cities of the substations and their capital Recife, which may also have affected the influence of labor.
