Developing a Toolkit for Assessing Labor Productivity on Construction Sites

Together with cost and schedule, labor productivity is an aspect of concern in construction. These aspects are closely related with each other. In the Vietnamese construction industry, labor productivity is low when compared to other countries. Most construction activities are directly undertaken on sites. Therefore, construction organizations are facing various challenges in managing on-site productivity. Currently, there is a lack of tools to manage productivity on construction sites. This paper aims to develop a toolkit to support labor productivity management at construction sites. Specifically, the toolkit includes a system of representative elements that could help to assess the labor productivity management level of project construction components according to the built-in scale. The toolkit was developed based on the productivity management factors of the American Society of Civil Engineers (ASCE) organization and then evaluated using the 5-levels rubrics scale. The labor assessment model includes main components that are decomposed into representative groups of factors. In each representative group, there are also criteria for evaluating sub-measures labor productivity. Finally, the proposed tool is evaluated by experts.
