THE INFLUENCE OF THE OPEN ENVIRONMENT ON THE WORK PRODUCTIVITY OF CONSTRUCTION PROJECT WORKERS

Abstract

Work productivity is the amount of work achieved by workers in a certain time and place. It is an indicator of whether a construction project can run effectively. Therefore, this study aims to determine the influence of the open environment on the work productivity of construction project workers, namely: solar radiation temperature, project contours, safety, relative humidity, work layout, wind, weather conditions, light intensity, visibility distance, color scheme, and pollution. Data was collected using the purposive sampling method and analyzed using the Structural Equation Modeling (SEM) program. The results showed that the variables with a positive effect of 35%, 35%, and 22% on work productivity are security, weather conditions, and work layout. The factors that demonstrated a negative effect of -31.6% and -33.3% are solar radiation temperature and light intensity. Results also indicated that the security and weather condition variables have the highest influence on worker productivity, hence, they are the guarantor of workers’ health and safety.
