Analysis of operation efficiency of tower crane in form work construction for multi-family housing

Abstract

High-rise apartment projects in Korea have been built up to twenty stories with three to fifteen hundred multi-family units. When these projects are under construction, operation of lifting equipment such as tower cranes substantially influences project costs and scheduling. In other words, the operation of an appropriate crane based on its lifting load is highly related to the execution of construction projects. Although many researchers have attempted to examine the optimal site selection for a tower crane, thus far, operation efficiency analysis of tower cranes has been fairly limited. The objective of this study is to analyze operation efficiency of tower cranes used for multi-family housing construction in Korea. The data were collected by measuring operation time and lifting load. The findings of this study will help project managers to make better informed decisions when they are planning to use tower cranes for multi-family housing. Additionally, the results will provide essential information to assess lifting capacity for additional loads by applying new construction methods.
