Unsafe behaviors are one of the most critical leading indicators of construction accidents; therefore, timely identification of unsafe behaviors, and understanding the rationale behind them, facilitate rectification, which mitigates the probability of accidents. Unfortunately, current inspection practices are heavily experience-driven and, thus, considered systematically vulnerable. In this presentation, a process-oriented inspection checklist was proposed for navigation purposes. An experiment was designed and conducted to validate this proposal. The results of this experiment purported that this navigation tool enhances selective attention on pre-determined critical risks without sacrificing overall inspection performance. Although preliminary results look promising, it is believed that network strategies should be utilized to identify critical risks with regard to spatial-temporal characteristics, facilitating optimization of inspection strategies.
