A Study on Vertical Zoning Algorithm of Real-Time Construction Lift Control for High-Rise Building

For the past few years, numerous super high-rise buildings have been built around the world. Among them, movement management of materials and labors is closely related to productivity of super-high rise construction. The objective of this study is to develop an algorithm which can increase productivity of lift operation on twin-cage and multicage temporary lift for construction site. The algorithm is expected to enable efficient response to complex movement in a super high-rise construction site by applying principles of the vertical lifting operation. It is expected that the algorithm may reduce working hours and traffic line through operation optimization. The developed algorithm can optimize lift operation time by using lifting cycleestimating method which is generated based on the fundamental concerns when lift scheduling is planned. Lifting cycle-estimation has become a vital part of an arithmetic computation based on lift selection algorithm which controls factors such as distance between each lift, among passengers, and distances among lifts according to moving direction. This and a follow-up study aim to develop unmanned smart construction hoist with a goal to improve productivity and safety of vertical lifting in super high-rise construction site.
