| Abstract |
The purpose of this study is to analyze the production system and actual conditions of the erection process of steel construction in Japan and Korea. On this paper I studied the difference and the sameness of the steel construction by contrast of the selection type of a specialist contractor and job-site work. The study has been performed by job site research and site observation. The results of this study are as follows: 1) The selection type of steel construction in Japan have a horizontal division and a vertical division. 2) But in Korea have a several vertical division only. 3) We must to reflect upon the temporary-bolt connecting by the exclusive temporary-bolt. 4) About 20% of the whole-time working is consists of over-time working. 5) The working time of Erection & Fit-up bolting worker is changes by number of member rather than steel weight. 6) The working time of Final tightening worker is strongly relate with the number of final tightening bolts. 7) From 164 to 214 sets of final tightening bolts can be tighten by 8-hour working/day. |
