Avaliação do custo de produção, produtividade e qualidade dos sistemas de alvenaria estrutural com blocos de concreto e de paredes de concreto, na construção de salões de festas de condomínio residencial na Região Metropolitana do Recife

Abstract

Building systems for residential condominiums are increasingly associated with characteristics such as short schedules, good quality and low cost. Therefore, a designer can opt for the structural masonry system, using reinforced concrete walls or structural concrete blocks, for example, depending on the purpose of the construction process and aspects such as cost or productivity. The construction of cast-in-place concrete walls, to the detriment of structural concrete blocks, has become an excellent alternative for construction companies, due to the speed of production. On the other hand, masonry with structural blocks, despite dispensing with the use of forms, which have high costs, require longer execution time. This article presents a case study, based on an analysis of two types of masonry systems, the result of monitoring the construction processes and comparisons between them, using non-conformities, control of the executive process, productivity and costs as general parameters. direct. The analyzes were carried out following the construction of ballrooms, in two condominiums, of two works located in the Metropolitan Region of Recife. Through simple methodologies and tools available at the construction site, it was possible to obtain information to generate comparative indices between the respective construction methods, in order to analyze costs, productivity and quality. The study concluded that for each type there are advantages and limitations, therefore, the most relevant parameters should be analyzed in the design decision, generally considering factors such as costs and productivity. In this study, the system adopted with structural blocks provided the greatest advantage, due to the cost parameter, which is a determining factor for the company to choose projects with this constructive system for the annexes, such as the ballroom.
