AEC industry has been known for budget overruns and delays for a long time. One important reason for weak performances is the difficulty to visualize the production flow, and the deficient information transmission between the different stakeholders involved in a construction project. The use of 3D models plays a significant role in facilitating the implementation of Lean principles, as it significantly improves the process visualization and supports the planning and coordination activities. This study portrays the utilization of VSM on a train station renovation project and proposes the use of a combined approach of BIM tools and Lean techniques for the coordination of MEP works.. BIM-Lean synergies were identified and set the foundation for the proposal of a team coordination approach combining BIM tools and Lean techniques. Besides an important reduction of non-added value activities and durations, the implementation of this approach achieved the alignment of interests of all stakeholders towards a common objective of meeting the overall project schedule. The findings show how a combined BIM-Lean approach improved workflow in MEP maintenance projects, and opens perspectives towards the generalization of the proposed approach into a practical Lean-BIM based production management method.
