Aditivos contratuais em obras públicas municipais: um estudo na região administrativa de Araçatuba (SP)

Abstract

The materialization of public works is one of the most tangible vectors of public policies in the territory, being essential to the promotion of urban development, social justice and the exercise of the right to the city. Despite the quality, deadline and cost, the works are constantly affected by interferences that hinder the fulfillment of the initial scope, making it necessary to enter into contractual amendments. In this context, the main objective of this work was to discuss the contractual amendments in public works of the Secretariat of Government and Institutional Relations (SGRI) in the region of Araçatuba (SP). The methodology adopted is descriptive in nature, with a mixed quantitative and qualitative approach, configuring itself as a multiple case study. The data obtained through the Official Gazettes and the Transparency Portals were analyzed with non-parametric statistical tests (Kruskal-Wallis, Mann-Whitney and Test U), comparing five portfolios of works (Building – Construction; Building – Renovation; Urban Infrastructure; Square; Leisure System). Among the 190 works analyzed, 129 (67.90%) presented additives: 33 only for the deadline, 44 only for cost and 52 with both. The deadline amendments reached an average of 108.68% in relation to the original schedule, predominating in renovation and construction works; Cost additives presented an average of 12.84%, with higher percentages also in renovations. The most recurrent causes involved unforeseen services, project changes, delays in transfers, and external factors, such as the Covid-19 pandemic. It is concluded that the weaknesses of the initial planning, the low technical capacity of the small municipalities and the inconsistency of the basic projects are the main determining factors of the additives. In addition, the analysis highlights the need to improve the preliminary stages, contractual management and the adoption of governance tools capable of reducing the incidence and intensity of additions in public works.
