The purpose of this study was to establish methodology for building up Architectural Expert Network using Social Network Analysis. For this study, Researcher Network in the field of BIM Technology was built up and analyzed using Social Network Analysis. BIM Technology was chosen since nowadays it is one of the most active fields of study in Architecture. To build up Expert Network and analyze it, analysis tool called UCINet 6 for Windows was used. For next study, process model was also presented, which can allow to analyze Expert Network in the other fields of Architecture. The results of this study can be utilized as follows. It can lead to develope Expert Recommendation System in the each field of Architecture and make Knowledge map in all fields of Architecture later.
