Otimização da orçamentação de obras na construção civil utilizando o software bim altoqi visus

Abstract

EThis study presents an applied approach to optimizing the budgeting process of public construction works through the BIM (Building Information Modeling) methodology and through the use of the AltoQi Visus software. The case study focuses on budgeting a public school located in the interior of the state of Ceará, whose projects follow one of the FNDE standard models and were developed in BIM. The research explores the strategic role of budgeting in civil construction, highlighting common cost estimation methods, the application of the BDI (Budget Difference Index), and the main public cost databases. The theoretical framework also addresses the fundamentals of construction planning and the Work Breakdown Structure (WBS), emphasizing the potential of 5D BIM for integrating the three-dimensional model with automated quantity takeoff and cost compositions. The methodology includes the practical application of AltoQi Visus, encompassing IFC model importation, WBS definition, composition association, 4D simulation, and technical report generation. The results demonstrate productivity gains, greater accuracy in quantity takeoffs, and enhanced budget traceability, proving the software’s effectiveness as a tool for achieving greater efficiency and transparency in public works budgeting.
