Evaluation of risk for construction safety of fabricated buildings based on analytic hierarchy process

Abstract

In order to assist the construction safety risk control of fabricated building, 17 safety risk factors were identified from the five dimensions of man, machine, material, management, and environment. The safety risk evaluation index system of the fabricated building construction stage is constructed based on the AHP (Analytic Hierarchy Process). The risk level is divided according to weight. The results show that the focus should be on the on-site safety staffing, the professional ability of the operators, the quality of additional tools, and the overhaul and maintenance of mechanical equipment. Enough attention should be paid to material storage and maintenance, operator safety awareness, deployment of safety protection measures, transportation protection measures, operator protection work, mechanical equipment selection, natural environment, safety inspection work plan, prefabricated component production quality, mechanical equipment installation, and removal. General attention should be paid to the surrounding environment, the safety production responsibility system, and the construction site environment.
