ANÁLISE DE CUSTOS PARA A CONSTRUÇÃO DE UMA HABITAÇÃO POPULAR COM AVALIAÇÃO DE DOIS SISTEMAS: estrutura de concreto armado com alvenaria de vedação em bloco cerâmico e estrutura de light steel frame

Abstract

The present work deals with a cost analysis, where it is proposed to make a comparison between the direct expenses to construct a single-family dwelling of popular standard using two different systems, being the industrialized constructional method light steel frame, in which the structure is composed of galvanized steel profiles, and the conventional constructional method, which uses reinforced concrete elements and masonry sealing. Due to the great housing deficit existing in the country, it is relevant to study ways of finding an economic solution for the mass construction of housing. It was defined a house model to be studied, as well as the direct cost worksheet for the construction using the conventional constructive method, and the same procedure was performed for the light steel frame system. Finally, the comparisons and final considerations were made, where reasons were indicated for the observed differences in costs. The costs for the conventional masonry work were defined based on the survey of the general quantitative of the project, considering all stages of the work, using SINAPI as a basis for obtaining the analytical compositions of the services and unit prices, for the job with the light steel frame system the budget was developed through price quotes made by the author himself. With the budgets made, it was possible to conclude that the unit costs per square meter of the study project are close, and belong to the same order of magnitude of the Basic Unit Cost indices, for both construction systems.
