This article delves the use of organization modeling to assess the impact of Lean construction concepts on project performance. The research calibrated four virtual models of construction project organizations developed using the Virtual Design Team (VDT) method and SimVision® VDT computational tool. The models were validated comparing their predictions with actual results obtained in the projects, and the assessment and approval of technical experts of the companies in the study. Then, the four models were used to evaluate the impact on project performance using alternative organizational designs, each of them inspired in Lean production concepts and principles. The results proved that VDT models can be used to evaluate the impact of the Lean concepts in projects performance, representing these notions in the organizational design and showing the benefits of implementing them. In general, the models predicted positive impact in terms of cost, time, variability and waste reduction in organizations inspired by Lean principles and concepts. These outcomes contribute to expand the uses of VDT methodology, proposing a method to include Lean principles in the organization design, and allowing companies to model Lean Project Management concepts at the planning and design phase, achieving improvements in terms of cost, schedule and variability
