To prepare future building professionals for interdisciplinary collaboration, the model of a vertical “Collaborative BIM Studio” was developed and performed in the academic year of 2008/09. Students of six different disciplines - architecture, landscape architecture, construction, structural, mechanical, and lighting/electrical engineering - were given the task to revise the prototype design of an elementary school while using building information modelling (BIM) technology for data collection, analysis, design development, data coordination, and project presentations throughout the semester. They were instructed by faculty of architecture, landscape architecture, and architectural engineering. The studio was evaluated using internal and external observation methods and surveys. The gathering of all design information in coordinated digital models provided the students with tangible experience in team organization and BIM workflow. All disciplines were closely engaged in each other's work, and feedback and synchronous communication were facilitated. Workflow observations and design actions indicated that the planning of model content and workflow at the beginning of a project are critical to successful design collaboration. The integrated environment and the use of BIM led to an intensive collaborative educational experience for both undergraduate and graduate students of the participating disciplines and to mutual understanding of technical, aesthetic and social aspects of a collaborative design process.
