Diretrizes de orçamentação e planejamento de obras – proposta para minimizar desvios de custos

Abstract

A good budget, aligned with good planning consistent with the conditions of a work can be responsible for a significant savings in the final value of the construction. When thinking about planning a work, the way in which it should be executed as well as its constructive method is a decision of paramount importance. The present work aims to carry out a comparative analysis of a work with conventional masonry using ceramic block, and a work with masonry using structural concrete block, from a model of standard housing unit Caixa Econômica Federal. Far beyond comparing the final cost of the work by both methods, the objective is to generate parameters that can directly influence the planning of the work, from results such as the ABC curve. In addition, to present parameters of incidence of high prices of inputs of great proportion in the work as a whole, based on the increasing price increase since the beginning of the covid- 19 pandemic, thus allowing to estimate increases during the execution of the work. The main result was a saving of about 10.72% in the final budget using structural masonry.
