Comparação de custos entre os processos construtivos em concreto armado e em alvenaria em blocos de concreto: estudo de caso em Toledo, PR

Abstract

Because of the competitiveness in the construction industry, a major priority of companies in the field of construction is the reduction of costs in running a project, so the savings generated in the construction process makes possible the transfer of property to customers. This fact highlights the importance of studying alternatives that balance price and quality. Why meet these requirements and generate greater rationalization in the construction process, the structural masonry has been widely used. This work presents a comparative, through a case study of the performance of the structure of a building in structural masonry and reinforced concrete. For this we analyzed the projects in the two structural building systems, a survey was made of the quantitative composition of materials and costs for each of the major subsystems that comprise the building structure. It was then possible to observe that the structural masonry building in the final savings is 20% compared to the same work with reinforced concrete building. This value applies for a job in the city of Toledo-PR, and therefore it is not recommended to extend this result to other regions.
