This research compared CAD and BIM, seeking to identify evolution, or revolution, in the field of building projects, focusing on municipal approval. The research sought to understand municipal, state and federal normative to approve architectural projects and studied CAD and BIM in the light of the technical documents generation submitted for building projects evaluation and approval. The aim was to compare the efficiency of 3D model for the analysis of projects in municipalities. The results identify adequacies and inadequacies on both platforms, but also formulate suggestions for improvements in the process of evaluation and approval of projects by local governments.
