Risk Analysis of Worker Movement Paths in the Heavy Equipment Operation Zone on the XYZ Surabaya Building Construction Project

Abstract

In a dynamic field work environment, the interaction between workers and heavy equipment is one of the most important sources of safety risk. The movement of workers in field areas operating with heavy equipment has a high risk potential, especially when the worker's path of travel intersects with the machine's work zone. Worker movement paths that are not safely designed can increase the potential for accidents, especially when crossing or adjacent to heavy equipment operating zones. This research was conducted on the XYZ Surabaya building construction project which has a high level of heavy equipment activity and a dense work area, giving rise to the potential for dangerous interactions between worker movement paths and heavy equipment movements in the field. Therefore, this study aims to analyze how much the level of danger that may be experienced by workers and show several danger hotspots with a high level of risk in the field using the multi objective function method in determining the field safety index value. The results showed that in the XYZ Surabaya Building construction project involving heavy equipment such as drilling bores, crawler cranes, and excavators, worker movement paths have varying levels of risk based on the working radius of the heavy equipment. The path with the highest level of danger is the movement from the container to the parking area, with a safety index value of 100. Followed by the path from the container to the iron fabrication area, which has a risk level of 75. Meanwhile, the path with the lowest risk level is found on the journey from the parking area to the diesel tank, and from the forming area to the diesel tank, each with a safety index value of 10.
