Resumo
O presente trabalho aborda e relaciona os sistemas de alvenaria estrutural e alvenaria convencional, ambos utilizados em grande escala atualmente, com um terceiro sistema composto de paredes de concreto armado moldadas in loco, definindo-os, apresentando suas características construtivas e comparando analiticamente os seus respectivos custos e produtividade, através de três empreendimentos, um para cada sistema. A metodologia utilizada na revisão da literatura e no estudo de caso baseou-se em informações de artigos, trabalhos e livros desta área do conhecimento, além da coleta de informações sobre composição orçamentária e produtividade para a execução das construções, por meio de orçamentos e cronogramas das obras. Para a produção das tabelas de quantitativos e preços das composições, utilizou-se a tabela SINAPI, permitindo a comparação de preços para a execução de um pavimento tipo intermediário e, posteriormente, o preço do metro quadrado para cada sistema construtivo. Entre os resultados encontrados, pode-se observar que, apesar do preço mais elevado para execução do empreendimento em paredes de concreto, obteve-se um prazo para a entrega final da obra de aproximadamente metade do tempo em relação aos outros dois, mostrando ser uma alternativa atraente em relação as demais.
The present work addresses and relates the systems of structural masonry, conventional masonry, both used in big scale now a days, with a third system composed of bearing walls moulded on the spot, defining them, presenting their constructive characteristics and analytically comparing their respective costs and productivity, through three buildings, one for each system. The methodology used in the literary revision and on the case study was based on article information’s, projects and books related to these topics, in addition to collected information’s about budget compositions and productivity for the execution of the constructions, through budgets and chronograms of the constructions. To elaborate the quantitative tables and prices for the composition, it was used the table SINAPI, allowing the comparison of prices for the execution of one intermediate floor plan, and, afterwards, the price per metre squared for each constructive system. From the obtained results, it is possible to observe that, even though the price is higher for the execution of a building with bearing walls moulded on spot system, it’s deadline is approximately half in relation to the other systems, therefore, being an attractive alternative in relation to the others.
