Crane overlap and operational flexibility: balancing utilization, duration, and safety

Abstract: Purpose With tower cranes being the site hubs, thoroughly planning and managing their operations can result in better construction performance. As urban spaces become more constricted, overlapping working radii of tower cranes becomes inevitable. While project planners are concerned with safety hazards, research has not comprehensively addressed workload distribution and synchronization of overlapping cranes. Therefore, this study aims at exploring the impact of overlapping cranes, used on high-rise buildings,… Show more

“…The third criterion considers hook position. If two crane hooks are within the intersection area, space conflict is likely (Al Hattab et al 2018). The fourth criterion further formalizes the previous criteria according to category, height, and motion path.…”

“…In earlier studies, the possibility of space conflicts was incorporated into tower crane planning as the objective index or constraint (Zhang et al 1999;Irizarry and Karan 2012). Later studies began to focus on quantitative evaluation of the lifting delay caused by potential space conflicts among tower cranes (Al Hattab et al 2018;Younes and Marzouk 2018;.…”

“…Cranes layout planning (CLP) is a complex combinatorial problem involving a series of decisions/factors to determine the crane type, quantities, location and supply points. These factors include site configuration and logistics, workload demand, space restrictions, weather conditions and construction support facilities that impose limitations on optimal crane layout (Warszawski, 1990; Marzouk and Abubakr, 2016; Al Hattab et al , 2018). Crane layout has been a challenging issue, especially the location problem, as it requires sufficient coverage of the lifting activities (Younes and Marzouk, 2018).…”

“…(Al-Hussein et al, 2006). Also, 4-D simulation was applied to validate the logic and setup of a lifting task scheduling model, identify spatial and capacity constraints for tower cranes, detect potential collisions among tower cranes during lifting tasks, analyze the utilization of each tower crane for balancing workload and planning deployment, simulate the tower crane operator's viewpoint, and so on (Irizarry and Karan, 2012;Wang et al, 2015;Marzouk and Abubakr, 2016;Sugimoto et al, 2016;Al Hattab et al, 2018;Ji and Leite, 2018).…”
