Análise de aditivos contratuais em obras públicas de um município do interior do Amapá

Abstract

The significant investments of the public sector in civil construction in Brazil highlight the need to ensure transparency and efficiency in the management of public resources. In this context, the primary objective of this research is to analyze the technical documentation of public works in the municipality of Porto Grande, in the interior of Amapá, identifying the main causes of contract additions related to time and cost and comparing these findings with existing literature. The theoretical foundation of the research included a detailed study of the current legislation on contract additions in public works, as well as a comparison between the old Law (Law N° 8.666/1993) and the new Public Procurement Law (Law N° 14.133/2021). Methodologically, the research is classified as a case study and documentary research, involving the collection of data on public works contracts, with an analysis of procurement methods, execution regimes, types of work, contracted values, and timelines. The data were analyzed both globally and individually, allowing the identification of the reasons for the additions, the additional contract value, and the time delays in the works. It was identified that renovation works had the highest incidence of contract amendments, with an average increase of 45.27% in costs and deadline extensions of up to 485 days. The comparison with the literature reveals that the identified reasons, such as deficiencies in the planning and design stages, are common in other regions and do not present significant peculiarities in the context of Amapá. The research suggests that implementing the practices recommended by the new Public Procurement Law may contribute to reducing the need for additions, promoting greater efficiency and cost-effectiveness in public works, considering the inclusion of new provisions in the legislation and a clear evolution when compared to Law N° 8.666/1993.
