The design stage is decisive for the Product Development Process, as it is in this stage that the main guidelines of the projects are defined, which directly affect costs, deadlines and production methods. In this sense, virtual prototypes have been used to approve project alternatives, perform engineering analysis, support production planning and present the product to customers. Thus, they allow the reduction of time and resources in decision-making, in addition to predicting problems that may lead to difficulties in execution. In this context, the research sought to optimize pre-existing projects of a popular standard residence through the development of a virtual prototype through the Autodesk Revit tool where it was possible to reconcile the structural, electrical, hydraulic and architectural projects, in addition to adapting such projects with the construction techniques used by the construction company. In this interactive process, the automatic method of detection of interferences (crash-detection) and the manual were applied, through the contribution of the stakeholders of the work. The estimated direct savings obtained per house built was around BRL 905.00, knowing that this development was a housing complex of 90 houses, a reduction of approximately BRL 81 thousand reais was obtained in total.
