Hazard identification and risk assessment in building construction projects in Abuja

Abstract

The study determined the most hazardous work item and assessed the risk level of hazard in building construction projects. The mean score method and the 5x5 matrix were used to analyse work, roof construction, lift installation, and steel structures with an average risk score of 11.48,11.01, 10.74,and 10.71 respectively, representing medium risk. The result of the hazards risk assessment of work items revealed that the most occurring hazards in the work items sampled were the collapse of building structures, falls from a high level, being struck or hit by falling objects, electrocution, and falls to a lower level. It was concluded that professionals in the industry would experience more medium-level risk in the study area. It was recommended that regular hazard risk identification and assessment should be conducted during project execution.
