Rotina de programação para geração de modelos BIM visando estimativas de custos

This study presents a comparison between general programming routine and reference from the literature. Both routines propose cost estimate in initial phases of project using generative associated to BIM, which involves generating model extracting quantitative data through Dynamo, Revit Excel software. The purpose this is refine allow variations construction by modifying only inputs, without having change structure for each new modeled solution. research strategy adopted work Design Science Research (DSR), oriented solution relevant pragmatic real-world problems. It has been divided into stages awareness, suggestion, development, evaluation completion. In order compare results, structural elements (beams, slabs pillars) building were routine. presented an error 12% relation budgeted was considered viable fast creation BIM models preliminary estimates, support decisions project.
