Otimização do uso de cremalheiras na construção civil: um estudo de cronoanálise e desempenho operacional

Abstract

In the construction industry, the search for efficiency and waste reduction drives techniques such as Lean Construction. This study focuses on optimizing the use of temporary elevators, aiming to reduce waste and improve operational efficiency. The objective is to study and apply chronoanalysis techniques and Lean principles to optimize the time and performance of two temporary elevators with different specifications. The methodology included the collection of quantitative and qualitative data, recording transportation, loading, and unloading activities. The main concepts used were chronoanalysis and Lean principles, which identify and minimize waste, such as waiting time and empty transportation. The results indicated that such waste reduces productivity and efficiency. The discussions propose low-cost improvements, such as a preventive maintenance schedule, and investments in smart sensors. The discussions propose practical and low-cost solutions to promote efficiency gains. This study highlights the importance of chronoanalysis and waste management to improve processes and increase competitiveness in the construction industry.
