Lifting planning for Roof system of Large span spatial structure is important because it is critical path. Purpose of this study is to investigate the influential factors of lifting planning of Roof system by analyzing the actual condition of lifting planning and to systematize the method of lifting planning. Range of this study is 14 internal Large span spatial structure which be truss system and rigid system. And method of this study is to analyze the date concerning the lifting planning. The result of this study is to classify the 5 types of the influential factors of lifting planning of Roof system and the 5 categories for the connection of support structure and lifting of main truss. This study classify the characteristic of each lifting method of construction on condition according to the classification of influential factors and the result of a correlation analysis.
