Abstract

The Civil Construction field embraces constant development. This development concerns constructive, planning, management and design methods. The absence of professional elaboration in any of those areas brings risks and costs for Civil Engineering and for society. The arising of pathologies due to inappropriate constructive methods, fault or absence of projects, as well as flaws during execution carries pathological problems, which overtax the contractor. Therefore, the NBR 13755, which deals with Ceramic covering of facades and external walls utilizing adhesive mortar, brought in 2017 a review to provide the need for controlling of the façade systems aiming the improved development of the construction field. The present work concerns the evolution of this regulation to fight the most frequent pathologies found in building facades, mainly regarding the requirement of a building facade project. To reach the goal, this work approaches the bibliographical research made on the subject. Then the methodology used for the study above was presented, approaching an specific survey done with professionals of the construction field about pathological manifestations and about the knowledge of the update of the regulation. Afterwards a general survey was made on the population about the way they see the importance of the facade aesthetic appearance, being able to see that it has high relevance for the final costumer. Then, based on the regulation constructive and design recommendations were made in order to avoid the arising of pathologies. It could be concluded that the aesthetic aspect has high importance both for the professionals and for the population, and showing how often these reviews of the regulation are known and used in the current buildings, also showing that the regulation approached the recommendations that were already made in literature, therefore providing technical support to ceramic covering of facades executed nowadays.
