Abstract
Background and Aims: Safety performance indicators play a crucial role in supporting managerial decision-making and evaluating control measures within safety management systems. Given the growing use of tower cranes in developing countries, this study aimed to develop a safety performance index for tower cranes during the operational phase.
Materials and Methods: In this study, tower crane safety performance measures were identified through expert judgment using the Delphi technique, and a checklist for assessing the safety performance of tower cranes was developed accordingly. In the next step, weights proportional to the impact of each safety measure on overall safety performance were assigned, and the safety performance index was calculated based on existing frameworks. Finally, the index was applied to two construction sites equipped with tower cranes in the city of Isfahan. All ethical considerations were observed throughout the study.
Results: A total of 56 safety performance measures were approved by the expert panel. The highest weights were assigned to “inspections by regulatory authorities”, “implementation of worker competency certification systems”, and “crane operating height”. A safety performance checklist for tower cranes was developed. The safety performance index ranged from 0 to 100, with scores of 81 and 91 obtained for the two studied construction sites, corresponding to moderate (yellow) and good (green) safety levels, respectively.
Conclusion: In this study, factors affecting the safety of tower cranes during the operational phase were identified through a comprehensive literature review and expert judgment, and safety performance measures with adequate coverage and high consensus were selected.
