Análise funcional e econômica da obra de requalificação da rua Iati – Jaboatão Guararapes com o uso dos parâmetros topográficos e do índice de suporte Califórnia

Abstract

Brazil is a country in the world where its road network predominates over other modes. However, the low quality of existing infrastructures in the country is clear. One example is the large urban centers where they are increasingly suffering from flooding, poor street and avenue conditions and scarcity of resources to implement new infrastructure. In addition, in several works the use of practical knowledge not linked to the existing technicians is observed, which leads to reduce the durability of new constructions. In this context, this research aims to compare the functional and economic performance in the requalification of Rua Iati, located in Cajueiro Seco in Jaboatão dos Guararapes, carried out by the municipal administration of the city, with some project scenarios of that same street with various solutions that adopt topographic parameters and routine soil tests in road works. To develop this study, Iati Street georeferencing, soil testing based on the main ABNT and DNIT standards, plani-altimetric topographic survey, street design in software Autodesk Civil 3D, project budgets and street measurements performed were performed. based on the actual unit costs of the companies responsible for performing these urban infrastructure services in the city of Jaboatão. It is demonstrated that there is a high use of financial resources, lack of technical parameters used and a lack of visibility in the quality of services performed, which leads to a reflection on how to use economic resources and ensure durability in newly refurbished streets of the Brazilian cities.
