Hazard Analysis in Building Construction Projects

Abstract

The activities of construction workers results to accidents happening more frequently at construction sites since building construction activities and trades are embodiments of health and safety risks and hazards. The aim of the study is to analyze the risk level of work items in building construction projects. Purposive sampling technique was adopted for data collection. The mean score method was used to analyze the most risky work items on building construction projects, result revealed that lift installation, electrical work, roof work and steel structure, with mean scores of 4.03, 4.00, 3.95, and 3.80 respectively were the riskiest work items. The risk prioritization number was used to analyze safety risk assessment, result revealed that roof work, steel installation, reinforced concrete and cladding had similar top three critical hazards, fall from high level, struck by falling object and building structure collapse. It was concluded that work related risk are strongly associated with construction trades, implying that construction safety risk management requires multiple management approaches. It was recommended that different approaches should be applied in the management of construction safety risks across building trades. The study will improve construction safety professionals' knowledge and awareness on safety risks and will enhance quality and reliability of risk assessment.
