The purpose of this study is to suggest and verify drawing required information standards in order to write BIM-based architectural design document required in construction environment in korea. Korea public procurement service is intending to increase subjects applied to BIM extensively by making BIM design compulsive in any construction from 2016. In architectural work environment, however, the guidelines are insufficient for preparing BIM architectural floor plans and institutional elements needed to utilize BIM, and among the problems, especially the lack of BIM architectural design document standards is essentially needed to be solved. Accordingly, the ministry of land, infrastructure and transport and related ministries in korea are promoting a variety of r&d projects to build up plans to optimize how to write BIM-based architectural design document. To draw drawing required information standards, this researcher extracted common factors from 50 architectural design floor plans in 15 small and medium and large architectural design offices being prepared by current practice and comparatively analyzed existing standards to write the architectural design document of related institutions such as association of registered architects and association of architects. Based on that, this author has drawn standards by classifying them into architectural object factors, those that can be visualized based on BIM, and non-architectural object factors which are the other factors. Also, to enhance the effectiveness of drawing required information standards suggested in this study and secure objectivity, this author held public hearings for those in charge of construction consent, architects, and related experts and conducted a survey. This study is expected to improve work efficiency and design quality in architectural practice.
