Execução e controle de obras de casas térreas em alvenaria estrutural

Abstract

Although late, structural masonry gained ground in the construction processes used in Brazil, mainly due to its high level of rationalization and greater speed of execution when compared to the traditional construction system (reinforced concrete and sealing masonry). However, to guarantee the advantages of this process, it is necessary that the means of execution get improved, in order to achieve the greatest possible efficiency. In addition, it is essential that there is a correct technological control of the procedures and materials used to ensure the safety of structural masonry buildings. However, it is seen that in many constructions these requirements are not correctly followed, often because they are seen as onerous or irrelevant, especially when applied to small buildings. Thus, this work aims to identify the main methods of execution and control of structural masonry works for one-story houses and to assess (through standardized forms) whether the actions taken by construction companies in the interior of the state of São Paulo follow the instructions of the updated Brazilian standard NBR 16868-2/2020. Using the case study methodology, the level of service of companies of different sizes to the demands of current technical standards was verified and the forms of management of companies linked to the execution and control of works were analyzed. In the end, it was noticed that companies with more market experience tend to meet the execution criteria better. Construction companies that undergo audit processes are more concerned with control procedures through laboratory tests. In general, the potential of structural masonry is still not fully achieved by the builders of single-story houses.
