• Abstract: This article examines the main challenges and strategies for structural cost estimation in public works under the integrated procurement regime, as defined by Brazilian Laws No. 12.462/2011 (RDC) and No. 14.133/2021. The study compares three structural estimation methodologies applied to the 8J Block project at the Federal University of Uberlândia: (1) empirical rates; (2) preliminary design based on a similar project; and (3) AI-assisted estimation. It evaluates the technical, economic, and contractual implications of each approach, revealing significant variations in costs and input volumes. The conclusion emphasizes the importance of using multiple estimation strategies to mitigate risks and guide decision-making in complex public construction projects.
