Determining Intervention for Behaviour-Based Safety (BBS) Implementation in Building Construction Project

The construction works value in country has been increased for the last 5 years, so does the workplace accident number that boosts consideration of safety issue in industry, including the listed private construction firm. Its revenue growth in the last 3 years, was offset by decreased total number of workplace accidents in contrary to the increased workplace’s major accidents number. About 75% of company’s workplace accident involved subcontractors, over 60% of its root causes were dealing with Unsafe Behavior, and 68% of workplace accidents in 2019 caused by Unsafe Action. It triggers a strong impetus to initiate Behavior Based Safety implementation, by the DO-IT (Define-Observe-Intervene-Test) approach using in-depth interview, structured self-assessment questionnaires and statistical tests. The findings deal with Safety Key Behavior (SKB) criteria in 17 areas of entire construction works through formulating at-risk behavior that leads to unsafe action by the workers, grouped into 3 circles of processes, i.e., execution, supervision and planning/ management. This study contributes to address mutual obligation between company and subcontractors in prioritizing safety behavior improvement to help the policy makers enhancing safety performance in the industry.
