The one of main characteristics of Korean traditional wooden architecture is the change of wooden structure through the flow of time. So the survey report deals with the change of wooden structure importantly. The purpose of this study was to find the change of wooden structure in same architectural heritage through the flow of time. Recently, the 3D scanner is widely used for survey way of architectural heritage unlike the conventional method. And it is rare to survey same architectural heritage again. So there is no data of same method in same architectural heritage with the time interval. And the survey equipment and method will change more rapidly to get the more acurate and efficient data. To find the change of wooden structure through the flow of time, it need to understand the characteristics of survey methods through the comparison and analysis. This study was to compare with the survey report in 1988 and 3D scan survey in 2011 about the change of the column-leaning in Heungchunsa Geungnakbojeon. 3D scan survey is more accurate than the conventional method as for the column-leaning. The cloumn-leaning of Heungchunsa Geungnakbojeon already had the tendency of leanning toward the front of the building. But the leaning of colunms toward the front of the building is not tend to progress from 1988 to 2011. And the tendency of column-leaning shows the various directions. So, it need to regular survey for the change of wooden structure in architectural heritage and need to study on the comparision with the surveying ways.
