Análise das principais causas de desvios de prazo na construção civil : estudo de caso de um empreendimento de implantação de rede de gás em São Paulo/SP

Abstract

Deviations of costs and deadlines are recurring challenges in civil construction. Increases in costs and deadlines in public and private works are recurrent in Brazil and in many other developing countries. Civil construction is one of the industrial sectors with the lowest rates of compliance with contractual deadlines and, according to studies carried out by the Construction Industry Institute (CII), it has the greatest waste and/or efforts without added value (58%) compared to the results of automobile industry which is only 26%. In this work, the author aimed to review the literature related to deadline deviations in order to determine the main causes associated with this theme. In a second moment, a case study of a gas network implementation work is presented, illustrating the main causes that implied deviation from the physical schedule of the work, comparing these causes with those presented in the literature. Despite the heterogeneity in relation to the contexts and global regions of the articles studied, there was support, based on the case study, of the factors identified in the survey of the bibliographic literature. At the end of the study, it was possible to verify that the problems of scope changes by the client and low productivity were the main factors that led to the delay in the schedule of the work studied.
