One of the main factors responsible for the reduction of the overall performance and efficiency of buildings is poor project management. Studies have found the integration between design and construction processes has become an important requirement for improving project performance. Considering Lean philosophy has the potential to better integrate design and construction activities. This paper evaluates the request for information (RFI) associated with the interface between architecture and structure of a BIM model. Methodology was qualitative and research strategy was case study of a virtual construction of a residential building in Fortaleza, Brazil, with 15.925,67 m² of floor area and an estimated cost of $9, 2 million dollars. 260 RFI were analysed, 110 of which were associated with conflicts between structure, architecture and the MEP systems. That represents 42% of the total RFIs, the highest percentage among other RFI categories, such as plumbing systems, architecture vs. MEP, electrical systems, architecture, and fire protection and gas systems. This study aims to improve the architecture-structure design interface, and to assist virtual construction crews on what to watch for and how to identify design problems before they are taken to construction site.
