According to 「Hwangnyongsa Temple Central Column Record」 among the remaining documents, under reconstruction the pagoda of Hwangnyongsa&s 9th floor was completed in July 872 on the lunar calendar. At that time, King Kyeongmun worried about sarira under its central column, saying the central column does not move, and then He ordered to lift the central column. So his servants lifted it on November 6th 872 and checked the sarira and put it back on November 25th on the lunar calendar. 「Hwangnyongsa Temple Central Column Record」 did not document how to lift the central column which is tens of meters. therefore, this study inferred the way the central column of the pagoda of Hwangnyongsa was lifted in 872, left as a mystery. For that, this study set various hypotheses and it researched and analyzed hoisting technique that is a way to lift the pagoda of Hwangnyongsa and a column. In conclusion, this study inferred the most suitable hoisting technique for the pagoda of Hwangnyongsa at that time, based on the research and analysis of each chapter.

The Cheomsungdae was built in the Silla dynasty during the reign of queen Seondeok. It has a round cylindrical structure with a flowing curved fa ade. The identity of the Cheomsungdae has not been revealed since there is not much historical evidence or documents about the building. This study is trying to investigate the building technique and method from the technical point of view of the past when it was constructed. There have been much work and studies done for the Cheomsungdae, but not much were focusing on the technical aspects of the building. In addition there are many questions and doubts about the hypothesis of the building technique of Cheomsungdae since there aren't any remaining documents or historical evidence supporting it. Among many questions, we think that the discussion on falsework technique is not considering traditional construction method of the Dujabee (a traditional construction technique using various tools and equipment for the stability of the building) technique. Therefore, it is hard to identify them as reliable historical facts. As the result of the study, we want to provide the basic data on the construction techniques of Korean traditional architecture and broaden the study scope of technical history by narrowing the errors. The study could be summarized into three points. 1. The historical architecture Cheomseongdae was constructed by using traditional crane techniques such as a Noklo (pulley ladder). Cheomseongdae was re-evaluated as a high level technology for the history of architecture. 2. The benchmark method on Cheomseongdae construction has been applied with a precise scientific method based on the geometrical principals using the central axis. 3. In terms of the history of Korean traditional architecture technology, as there aren't many studies done we proposed various basic data for the traditional crane techniques and criteria of Korean traditional architecture technology. We could expect various and active studies for the technical approach of the history of architecture.
