Desafios de planejamento e logística na execução de fachada complexa em obra de grande porte: um estudo de caso

Abstract

This study analyzed the main planning and logistics challenges in the execution of complex façades in a large-scale project located in João Pessoa – PB, Brazil. Through a case study, the research sought to understand how architectural and constructive particularities directly influence productivity, site logistics, and quality management. The methodology combined direct observation, interviews with site professionals, document analysis, and photographic records, enabling a critical evaluation of construction processes in light of technical literature and applicable standards. The results revealed that executing façades with asymmetrical volumetry and mixed cladding systems significantly increased construction complexity. Team productivity was affected, particularly in critical activities such as plaster guides and ceramic tile installation, whose outputs remained below planned levels due to irregular geometry and the constant repositioning of suspended scaffolding. Additionally, material storage logistics, adverse weather conditions, and workforce turnover emerged as decisive factors for delays and rework. The critical analysis, however, highlighted that management tools such as the Last Planner System (LPS) and the Percent Plan Complete (PPC) contributed to greater planning reliability and helped mitigate the impacts of observed constraints. It was also found that adopting mixed cladding systems offered both advantages and limitations: paint and texture allowed for faster progress but with lower durability, whereas ceramic tiles provided higher resistance but required stricter technical control and showed reduced productivity. In conclusion, the execution of complex façades demands detailed planning, integrated logistics, and adaptive management in order to balance aesthetic innovation, technical performance, and construction feasibility. As a practical contribution, this study proposed improvements related to the use of 4D/5D BIM, just-in-time logistics, workforce training, preventive maintenance of equipment, and climate protection strategies, reinforcing the role of efficient management as a central element for the success of projects of this nature.
