A Study on the Effectiveness of Worker in Steel Roof Structure Installation

Abstract

      The objective of this study was to determine the effectiveness of the steel roof structure installation. The data collected on the workers in the housing project in Chonburi. There are two parts for data collection which are the project overview data by using Field Rating technique and collecting data of group of workers in steel roof structure installation by using Five Minute Rating technique. After that, data of workers in steel roof structure installation activities are analyzed by using Crew Balance Chart method and proposed methods to improve the work effectiveness. The data collected in this study consisted of the project overview of the worker, the work process of the steel roof structure installation, and the work data of each worker. In the analysis of the data, it was found that the effectiveness of the overall project assessment was equal to 66.31%. The steel roof structure installation activity effectiveness was equal to 45.83%. The steel roof structure installation, it was found that the workers with the highest effectiveness were 95% and two workers with an effectiveness value of 0. To improving the work effectiveness was using the Crew Balance Chart technique. Therefore, the effectiveness of steel roof structure installation increased from 45.83% to 68.75%. Suggestions for improving work process are shifting the way each worker works to increase the effectiveness and reduce the number of unnecessary workers, thereby reducing labor costs and increasing the efficiency of the work of the steel roof structure installation.
