Desperdício e gestão de mudanças: análise de um sistema de revestimento em edificação

Abstract

This study analyzes the application of textured coatings on façades, focusing on the importance of proper planning and compliance with technical standards to ensure performance and durability. In addition to providing aesthetics, the façade protects the building from harsh weather and preserves its internal systems. The case study conducted on a project in João Pessoa (PB) identified failures in the planning and execution of the façade, such as the inappropriate selection of textured coatings without proper assessment of costs, durability, and technical requirements. The lack of quality control and a suitable design compromised the system's performance, leading to additional costs and delays in construction. The study also points out gaps in Brazilian standards, which do not fully address the procedures and performance parameters for textured coatings, limiting the adoption of best practices. The applied methodology included a detailed investigation of the construction company, its internal practices, and the planning of the façade. The analysis highlighted discrepancies between the proposed design and its execution, suggesting that more careful planning, combined with better developed standards, could have prevented many issues. The proposed recommendations aim to enhance the design and execution of façades, considering criteria such as cost, climate, functionality, and aesthetics, as well as contribute to the development of more specific technical standards for textured coatings on façades, thereby improving the quality of construction processes in the industry.
