Since the construction industry in developed countries has encountered a serious shortage of construction workforce, one of the solutions is to brought in foreign workers where the labor cost is relatively lower. However, productivity issues are still encountered due to the poor management system for foreign workers. Constant monitoring of foreign labor activities can obtain comprehensive information in determining root causes of inefficiency. Column formwork activity is used in this study since the activity is involved in nearly every building construction project and is easily identifiable. This study presents a construction worker productivity evaluation by comparing the productivity of the foreign worker to the local worker with the integration of a deep learning method, named You Only Watched Once, to recognize workers’ actions. Based on the result findings, the YOWO model recognized the worker’s actions with proper evaluation metrics of 78.3%. The recognized actions are then used to measure the productivity for each of the worker based on the duration and identify the ineffective action of the foreign worker’s activity. The result shown that the assemble action of foreign worker is identified as the ineffective action and has the highest priority to be enhanced through training and education.
