Gestão das tarefas na construção civil por meio do Last Planner System: estudo de caso em uma edificação vertical em Curitiba - PR

Abstract

The construction sector, although representing a significant share of the national economy, still faces challenges related to the efficient management of deadlines, labor, and material resources. The high incidence of waste, rework, and non-valueadding activities has driven the adoption of new construction management philosophies. In this context, Lean Construction emerges as a viable alternative, with its main tool for on-site implementation being the Last Planner System (LPS), which aims to improve predictability, collaboration, and production control. This study aims to simulate the application of the Last Planner System in task management for a vertical building with 22 floors and 3 underground levels, located in Curitiba, Brazil. The methodology involved planning meetings, constraint analyses, activity rescheduling, and monitoring of indicators such as Percent Plan Complete (PPC). The simulation allowed for the evaluation of the benefits of the Lean philosophy when applied systematically, highlighting improvements in schedule adherence, reduction of operational failures, and greater integration among stakeholders involved in the construction process. The results showed that the adoption of LPS provides significant gains in control, communication, and productivity, enabling a more stable and organized environment for decision-making. Thus, the study reinforces the importance of implementing collaborative planning systems as a strategic tool for the advancement of the construction industry.
