Construction of roof structure, cable suspended structure, for Pusan main stadium is adapted a lifting method that is VSL lifting system. 5 precesses are practiced for erection of the roof structure including the first lifting process for erection of upper cables and the second lifting process for erection of lower cables. Since all cables of this roof structure with two open speller sockets are determined their length, some cable were wrong length, the roof structure would be unstable. But At complete of erection for the roof structure each cab3e is attained to theoretical tension force with average $4\%$ errors.

In this study, interviews are held with the faculties of two elementary schools on narrow sites located in Seoul to examine the existing problems of the elementary school on narrow site and the need for the new facilities of the elementary school on narrow site in order to derive the implications for the planning guidelines of such school construction. As a result of the survey, it was found that the substitutes of the playground installed in the elementary school on narrow site were not suitable for physical play activities, physical education class activities, and other curriculum operations. In order to secure an adequate physical activity an space for elementary schools, faculty members were demanding that the entire floor or rooftop of the school building be spatialized for physical activities. Additionally, problems such as noise generation and the lack of special rooms and public space were occurring in the elementary schools on narrow sites and are being deteriorated by accommodating an over number of students, and therefore policies are required to ensure that the appropriate number of students are maintained in the case of the schools on narrow sites.
