Construction lifts are key equipment used in the vertical transportation of resources in supertall building construction. Also, according to the increase of vertical lifting distance, construction lifts are becoming more important for successful projects completion. However, a limited number of construction lifts were hard to handle the lifting load during peak-time in which the construction resources are concentrated. Also, a large number of stops caused a decrease of lifting efficiency. Consequently, these problems cause an increase of lifting time of the resources and construction delay can occur. Therefore, it is necessary to apply concept of double-deck elevators to construction lift in order to decrease the lifting time of the resources. In this study, two discrete event simulation models using the CYCLONE are developed to evaluate the lifting time of workers, who are required to be located on the upper floor workplace in the morning peak-time. Also, comparative analysis of lifting efficiency between single-cage lift and double-cage lift is conducted. As a result, the proposed simulation model of double-cage lift shows a remarkable decrease of 38.0% compared with single-cage lift. This result could contribute to set the direction of development for double-cage lift. Furthermore, it is expected to support construction manager to find optimal hoisting plan with minimum lifting time in supertall building construction.

More and more high-rise buildings are being erected in extensively populated countries such as China nowadays with the requirement of higher living standards. However, on the one hand, with the development of aging society, the labor shortage has become a remarkable problem; on the other hand, the danger and difficulties in construction increase significantly with the height of the buildings. Thus, the application of automation and robotics technology is expected to ease such problems and concerns. Up to now, various methods and systems using automation and robotics technology have been proposed to be used in high-rise building construction. This paper summarizes the major advance on the application of automation and robotics technology in high-rise building construction through a literature survey and suggests directions of further research in this field. First of all, the research scope, the method and the results of the literature survey are presented. Then, based on the survey results, the relevant applications are summarized regarding the three parts of high-rise buildings, i.e., earth and foundation work, superstructure erection and faç ade installation. Finally, the future directions and opportunities mentioned in existing research are summarized and discussed. This paper provides a valuable aid in future research and application of automation and robotics technology for high-rise buildings.

Purpose The objective of this study is to develop an algorithm which can increase productivity of lift operation on temporary twin-cage and multi-cage lifts for construction sites. the algorithm is developed for optimizing operation efficiency at high-rise construction sites. Moreover, it is expected that the algorithm can reduce working hours and traffic queues through operation optimization. Method The developed algorithm can optimize lift operation time by using a lifting cycleestimating method which is generated based on the fundamental concerns when lift scheduling is planned. Lifting cycleestimation is a vital part for an arithmetic computation based on lift selection algorithm which controls factors such as distance between each lifts, among passengers, and distances among lifts according to moving direction. Results & Discussion We carried out surveys and conducted interviews with mechanical and construction professionals to analyse fundamental considerations of material lifting operation planning. We extracted the weight of each of the relevant factors. Based on the weight of factors, we set the lifting cycle-estimate suitable for high-rise buildings. The optimized operating algorithm is extracted through lifting cycle-estimates. Finally, we propose the prototype of an interface that is embedded into the lift with the optimized operating algorithm.
