The Relative Factors Shaping Construction Workers' Behaviors and Leading to Accidents

Abstract

Most construction workers’ behaviors are shaped by task objective constraints and their capability during the operation. This research describes the construction workers’ behaviors are an interaction between the task demand and the worker capability. The relative factors that influence construction workers’ behaviors have been determined through the Delphi process and Analytical Hierarchical Process (AHP). The panel participated in these processes was represented by 9 safety experts who were specialized in high-rise building construction. Results of the analysis showed that 23 task demand factors and 12 worker capability factors were determined by 2 rounds of the Delphi process under the expert’s consensus. The weights of these factors were determined by utilizing the AHP. The most weighted factor of the task demand was the Societal and Environmental Impact Awareness Factor. The Foreman’s Communication Ability Factor was the dominant weighted factor of the capability. The factors and their relative weights can guide practitioners to manage the project resources safely and efficiently.
