Avaliação do atendimento à NBR 15575-3 quanto aos requisitos para os sistemas de pisos em empreendimentos habitacionais de interesse social

Abstract

Given the growing demand from users and also the number of pathological manifestations in the flooring systems in social housing developments, NBR 15575 defines the requirements to be fulfilled by the component systems of buildings, attending to the performance requirements in order to ensure the quality of the delivered product. Thus, the present study intends to evaluate the compliance with NBR 15575-3 regarding the requirements for flooring systems in social housing projects. As a way of obtaining data, a checklist was elaborated, comprehending all the items of NBR 15575-3, which was applied to four constructions, integrating social housing programs, located in the city of Toledo/PR. In order to do this, were analyzed projects, descriptive memorials, quality plans made available by the construction companies and technical reports from the suppliers of materials. For the evaluation, the data were grouped according to the type of requirement, the agent responsible for its compliance and also the projects analyzed and, for each category, the compliance rate with the standard was identified. The main negative points found were in relation to structural requirements, fire safety and health, hygiene and air quality, in addition to problems concerning the design process of the buildings. Besides this, a lack of standardization in the services provided by the evaluated construction companies was observed, which contributes to a significant variation in the quality of the buildings. Thus, several corrective measures were indicated, such as the assignment of professionals responsible for verifying and ensuring the performance of the buildings and training employees about the requirements of the performance standard. The insufficient compliance with NBR 15575 is worrying, especially in relation to social housing projects, but with simple measures it is possible to improve this scenario and deliver higher quality products to the families.
