Gestão de obras públicas : análise da utilização de planilhas referenciais no desenvolvimento de projetos

Abstract

This study aims to analyze the problems and limitations of the reference spreadsheets hypothetically used preferentially in public works bids, mapping the lack of available items in these databases and identifying possible economic consequences in contracts and execution difficulties in the works. For this purpose, exploratory research was conducted due to the high availability of publicly available data in this field, notably through the Transparency Portals of municipal governments. Both quantitative and qualitative approaches were used in budget spreadsheets of recent public works bids conducted by the Municipal Department of Works and Urban Services of the Municipality of Contagem/MG in the years 2018, 2019, and 2020. Particularly, a case study was adopted, focusing on the financially most relevant item of a project from this department - asphalt pavement. It was concluded that there is a clear preference for the use of existing reference spreadsheets, such as those from the National System of Costs and Indices of Civil Construction - SINAPI, to the detriment of composing specific spreadsheets for the services comprising a project, both due to the convenience of their adoption and the influence of Brazilian legislation itself. This choice inhibited the use of customized items for each project and generated generic budget spreadsheets, compromising the quality and durability of engineering services, as evidenced by the studied example of road pavement in the aforementioned city.
