摘要
Between 2005 and 2015,the Brazilian real estate market experienced strong growth,driven by the stable scenario of the Brazilian economy and policies to encourage real estate credit.With this demand,the companies of the sector sought to be more competitive in the market.One of the measures adopted is the search for more efficient executive processes.While the traditional manual methodology for underlayment predominates in the country’s construction sites,a self-levelling underlayment presents a tendency towards mechanization of executive construction procedures.This paper aims to present a case study of a residential construction in Rio de Janeiro,which used self-levelling underlayment technology.Comparisons regarding cost and productivity of both methodologies were made to evaluate the viability of the self-levelling underlayment in future construction sites.Data obtained from other constructions were used to estimate the productivity and cost of the traditional underlayment levelling.The results demonstrate that the use of self-levelling underlayment has potential to be widespread and used in the constructions in Brazil.
