Loss of life, death, and harm to the property are the implications that will arise if the crane handling processes and standards are not properly performed. There are several factors that affect the safety of tower crane operation in construction that can be put into four main factors that are project condition, environment, human factor and safety management. From those factors, the human factor is the most common reason for the accident that related to tower crane operation to occur. Human error such as lack of communication, inexperienced worker, disobeying the safety procedure that provided and lack of supervision has been the contributor to this accident happened. This research, therefore, addressing the issue about the most common causes of tower crane accidents that happen on the construction site.
