Development of Safety Plan Based on Work Breakdown Structure to Determine Safety Costs for Building Construction Projects. Case Study: Lower Structure Building

Abstract

The construction industry has an important role in the economic development of the country, especially developing countries. However, along with the increase in the construction sector, work accidents in the construction sector also increased. This accident has a negative impact on the project, such as loss of life, material, time, and others. The risk of workplace accidents can be prevented through a well-designed safety management system. The prevention of the workplace accidents can be done by identifying potential hazards that occur in each activity contained in the work breakdown structure (WBS). Identification of potential hazards is needed to be planned well so that the construction companies can take the best preventive action against any potential hazards that exist in each activity of the construction projects, so the safety performance can be improved. After the potential hazards have been identified, then the preventive actions are taken to control the hazards to minimize the safety risk rate. The implementation of safety programs requires costs. But there is no separate budget in this sector that make the implementation of the safety management is still not optimal. Thus, the financing of the safety management system was taken from the project budget, which led to a reduction in the profits of construction companies. This study aims to develop the cost of safety management system based on work breakdown structure on the building lower structure work. The results of this study are the standardized WBS of the lower structure of buildings, potential hazard sources in the lower structure of the building construction projects, the preventive action to each potential hazards in each activity, and finding the safety cost components based on work breakdown structure with the aim of improving the quality of the occupational health and safety management system and reducing work accidents in the building construction projects.
