Application of Methods Analysis to Steel Erection Tasks: Identification of Factors Affecting Labor Performance

Abstract

Work methods play an important role in the performance of a task. When a worker is required to perform additional movements, use several tools and carry additional materials to perform a task, his/her performance can be affected. An analysis of task durations in the steel beam installation process showed that factors such as the use of personal protective equipment (PPE) can affect task durations. It is of interest to determine what aspects of the tasks are different (i.e. handling of tools and materials and difference in required motions, etc.) and can affect performance. An analysis of these differences provides valuable information that can be used to improve steel erection performance without adversely affecting the safety of the worker. This paper presents results of analysis of the method of the steel beam installation process considering the tasks involved in the process. The results show that factors such as the use of PPE and the length of steel beams play a role in differences in task performance.
