The Productivity Analysis by Slab Formwork of Structural Frame Work in Tall Building Construction

초고층 골조공사의 바닥 거푸집별 생산성 분석;기준층 3일 공정을 중심으로

A tall building construction is needed to reduce the construction duration for project profitability. Reducing the cycle time of typical floor in the structural frame work which have the largest duration in the whole construction, greatly affects construction duration. Nowadays, some projects are accomplished in the 3 day cycle. In order to accomplish efficiently 3 day cycle, productivity information of similar projects is supported. Therefore, this study proposed labor productivity and application by slab formwork to construct by the 3 day cycle. In order to perform an analysis, we selected 3 cases and analyzed the labor productivity on the basis of the amount of slab forms, labors, and durations. Then, we performed the questionnaire to analyze the application by formwork of tall building construction engineers. This study will contribute to establish a reasonable scheduling in structural frame work of a new similar project.
