Diagnóstico sobre a perda de recursos físicos na execução de emboço interno: um estudo de caso

Abstract

The NBR 13749 - Revestimento de Paredes e Tetos de Argamassas Inorgânicas (ASSOCIAÇÃO BRASILEIRA DE NORMAS TÉCNICAS, 1996), suggests that the permissible lining thickness of walls is at least 5 mm and not exceeding 20 mm. Thickness larger than 5 cm into trouble not only overloads, but also to shrinkage and cracking likely. In this work it was observed that the plaster internal walls, very underestimated by step estimators and engineering staff, including academics, requires care in implementation, especially in the earlier steps. We chose the case study as research methodology, applying measurements worksheets for professionals involved in the process, which are directly involved with the performance indicators obtained in this work. It also made it possible to observe that in the Building, where it still reigns craftsmanship, good or bad execution of the step considered is directly related to psychological factors empirical hand labor. Finally, the study has resulted in the fact that the productivity of the team that will run the internal plaster have influence in significantly higher total cost than if the step loss percentages are deemed incorporated and generation of debris.
