Desenvolvimento de ferramenta com suporte da tecnologia BIM para elaboração de orçamento de obras

Abstract

The traditional approach to budgeting, based on manual extraction of quantities from 2D draw ings, poses significant risks of human error, impacting accuracy and resulting in losses. The disruptive methodology of Building Information Modeling (BIM), coupled with the concept of interoperability, emerges as an effective solution, enabling the automation of quantity takeoffs and reducing errors. While most BIM software in the market supports the IFC format, its use for automating the budgeting process is limited to a few expensive tools, posing a financial challenge for designers or companies. In this context, this work aimed to develop an accessible BIM tool, successfully applying it to a construction budget based on an IFC-format BIM model. From this work, it is concluded that, despite the challenges of BIM usage, especially in maintaining model quality, the benefits in terms of speed, precision, and accessibility outweigh the difficulties. Fur thermore, the application of the developed tool for budgeting a construction project demonstrated the effectiveness of the BIM methodology in handling complex projects.
