Digital restoration of non-verbal expressions is difficult to trust unless the documentation. The purpose of this study is a new documentation methodology that can intuitively confirm the basis for restoration. The technical method utilized the BIM program function by referring to Italia's VRIM and Korea's HBIM cases. And the direction of documentation distinguishes between 'positivism' based on archaeological data and 'interpretivism' based on hypotheses. Specifically, it was applied to the 'Mireuksa Restoration Project' and tried to document it experimentally. This documentation proposed a framework for recording evidence according to sources based on the context of regions. Technically, the data organized in the Excel DB were directly input into the 3D model using the BIM program function. So, the user was able to intuitively review by matching the absence of the model and document information. The documenting method of this study is flexible to modify the restoration information whenever new evidence is found. And it has the advantage of being able to easily inform by converting it to IFC format.
