Impactos das falhas de projeto na execução do rebaixamento da Av. João XXIII em Teresina-PI: um estudo de caso

Abstract

The study analyzed the impacts of design flaws in the execution of the lowering of João XXIII Avenue in Teresina, Piauí, one of the main road interventions in the capital of Piauí and part of the city's ring road. The research is based on the recognition that deficiencies in the design and compatibility of engineering projects are recurring causes of delays, cost overruns, and loss of efficiency in public works. The overall objective was to assess the technical, financial, and time impacts resulting from design and compatibility flaws. Specifically, it sought to identify inconsistencies, analyze contract amendments and schedule extensions, comparing the results with technical standards and specialized literature. The research is characterized as a case study, with a qualitative and quantitative approach, based on the documentary analysis of technical reports, executive projects, contract amendments, and the Project Review during the Construction Phase (RPFO). Geotechnical, structural, and drainage failures were identified, such as inadequate excavation methods, inconsistencies in bracing beams, incompatibility of the drainage system, and lack of pile coating. These deficiencies resulted in an approximate 9.9% increase in the cost of the project and a 180-day extension of the execution deadline. It was found that design flaws were decisive for the impacts observed, confirming the importance of interdisciplinary compatibility, timely executive review, and the use of technologies to prevent failures and increase the efficiency of public works.
